The present disclosure relates generally to security/automation systems, and more particularly, to addressable devices in security/automation systems.
The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.
An example implementation includes an addressable device having a base unit mountable on a structure. The addressable device further includes a device head removably mountable onto the base unit. A removable addressing mechanism is removably mountable onto the base unit and is configured for setting an address for the addressable device. The device head includes an optical address detection mechanism that, when the device head and the removable addressing mechanism are mounted onto the base unit, is configured to align with the removable addressing mechanism to optically read the address configured in the removable addressing mechanism. The removable addressing mechanism is electrically isolated from the base unit, the device head, and the optical address detection mechanism.
Another example implementation includes a removable addressing mechanism having multiple designated positions for configuring an address for an addressable device. The removable addressing is removably mountable onto a base unit of the addressable device. The base unit is mountable on a structure. The addressable device further includes a device head that is removably mountable onto the base unit. The device head includes an optical address detection mechanism that, when the device head and the removable addressing mechanism are mounted onto the base unit, is configured to align with the removable addressing mechanism to optically read the address configured in the removable addressing mechanism. The removable addressing mechanism is electrically isolated from the base unit, the device head, and the optical address detection mechanism.
A further example implementation includes a base unit of an addressable device. The base unit includes a receiving portion configured for removably mounting a removable addressing mechanism thereonto. The removable addressing mechanism is configured for setting an address for the addressable device. The base unit is mountable on a structure. A device head of the addressable device is removably mountable onto the base unit. The device head includes an optical address detection mechanism that, when the device head and the removable addressing mechanism are mounted onto the base unit, is configured to align with the removable addressing mechanism to optically read the address configured in the removable addressing mechanism. The removable addressing mechanism is electrically isolated from the base unit, the device head, and the optical address detection mechanism.
To the accomplishment of the foregoing and related ends, the one or more aspects comprise the features hereinafter fully described and particularly pointed out in the claims. The following description and the annexed drawings set forth in detail certain illustrative features of the one or more aspects. These features are indicative, however, of but a few of the various ways in which the principles of various aspects may be employed, and this description is intended to include all such aspects and their equivalents.
The disclosed aspects will hereinafter be described in conjunction with the appended drawings, provided to illustrate and not to limit the disclosed aspects, wherein like designations denote like elements, and in which:
The detailed description set forth below in connection with the appended drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well known components may be shown in block diagram form in order to avoid obscuring such concepts.
Some present aspects implement an addressing mechanism into a base unit onto which a device head of an addressable device in a security/automation system is mounted. The addressing mechanism in the base unit according to the present aspects is removable, non-electronic, and optically readable. In some non-limiting aspects, for example, the addressing mechanism may be a removable non-electronic switch array, a removable address pennant, a tag, etc. The addressing mechanism allows for configuring an address for the device. The device head, which is powered by electricity, determines the device address by reading the addressing mechanism in the base unit of the device, without needing to pass any electrical current through the base unit. If the device head has to be replaced, the device address remains with the base unit, thus no further addressing configurations are needed upon replacement of the device head. Also, since the addressing mechanism is removably implemented in the base unit, an installer may remove the addressing mechanism from the base unit, configure or re-configure the addressing mechanism to a certain device address, and then plug the configured or re-configured addressing mechanism back into the base unit.
In some aspects, the device head may include, for example but not limited to, a sensor/detector unit, a notification unit, etc. For example, in some aspects, the addressable device may be a fire alarm peripheral such as an activation or notification device. The fire alarm peripheral may include a base unit that is permanently installed on a wall or ceiling, and a device head which mounts onto the base unit. The addressing mechanism in the base unit may be used for setting a unique address for the addressable device in a security/automation system that includes multiple addressable devices, so that each addressable device in the security/automation system may be uniquely and individually recognized and addressed. In one non-limiting aspect, for example, the security/automation system may include a loop of up to 250 fire alarm sensors/notification devices (e.g., a pair of wires that provides power and signal connectivity between a fire alarm control panel and up to 250 fire alarm peripherals), where each sensor/device is configured with a unique address. In one non-limiting aspect, for example, the addressable devices in the security/automation system may include an emergency alarm system peripheral, such as a hazard detector, an intrusion detector, a notification appliance, etc., where the peripheral includes a base unit that is in permanently installed on a wall or ceiling, and a device head which mounts to the base unit. In these aspect, the addressing mechanisms provided herein easily and efficiently assign addresses to such emergency alarm system peripherals.
Some other systems may implement an addressing mechanism in the base unit of a device or in the device head, where the addressing mechanism includes electronics and dip switches configurable for setting an address for the device. However, in order to read the address of the device, these systems may require an electric current to be run through the addressing mechanism. Some other alternative systems may implement a purely-electronic addressing mechanism that does not include any dip switches. However, these systems may require a special tool (e.g., a software mechanism) to update the address of the device. Unlike the aforementioned systems, some present aspects implement a non-electronic addressing mechanism that does not require any electricity to be run through the base unit of the device. Also, the non-electronic addressing mechanism according to the present aspects is implemented in the base unit and stays with the base unit during replacement of the device head. Therefore, replacement of the device head does not pose the risk of corrupting the device address.
Some other systems may implement a non-removable addressing mechanism in the base unit of a device. In these systems, should a base unit need to be replaced, a service technician would have to set the address for the replacement base unit, and there is a chance that the technician might make a mistake, thus costing time and energy to trace where the error lies. Further, the base unit may be placed on a ceiling or high up on a wall, thus causing difficulty for the technician to change an address when necessary. Unlike the aforementioned systems, the removable addressing mechanism according to the present aspects allows for an installer to remove the addressing mechanism from the base unit, move to a convenient location, configure or re-configure the addressing mechanism to a certain device address, and then plug the configured or re-configured addressing mechanism back into the base unit that is located on a ceiling or high up on a wall. For example, in some non-limiting aspects, the addressing mechanism may be implemented using a removable address “pennant” on which the address can be configured away from the base unit (for example, while the installer/technician is standing on the floor rather than on a ladder and reaching overhead), and thereafter the configured address pennant is pluggable into the base unit.
Turning now to the figures, example aspects are depicted with reference to one or more components described herein, where components in dashed lines may be optional.
Referring to
While some aspects below may be directed to smoke detectors, the present aspects are not so limited and are applicable to other systems where addressable devices are fixed to building walls or ceiling or other structures, for example, but not limited to, notification appliances or other emergency detectors or annunciators, home automation devices, etc. In some aspects, the terms “device head,” “detector head,” and “sensor head” may refer to the transponder part of a notification appliance device that can attach to a base unit of the device.
The base unit 104 of the addressable device 100 includes a removable non-electronic addressing mechanism 108 for setting an address for the addressable device 100. An optical address detection mechanism 106 in the device head 102 is configured to “see” the address configured in the removable non-electronic addressing mechanism 108 in the base unit 104. There are no electronics in the base unit 104.
In the non-limiting example aspect illustrated in
In one non-limiting aspect, for example, the optical address detection mechanism 106 in the device head 102 may include an array of light-emitting diodes (LEDs which may be visible or IR) and a corresponding array of optical sensors/receivers. The optical address detection mechanism 106 is align-able with the removable non-electronic addressing mechanism 108 in the base unit 104 so that, when properly aligned, the optical address detection mechanism 106 in the device head may “see” the address configured in the removable non-electronic addressing mechanism 108 in the base unit 104. In one non-limiting aspect, for example, the optical address detection mechanism includes multiple LED/optical sensor pairs, and each LED/optical sensor pair is configured for aligning with and optically reading one address bit configured on the removable non-electronic addressing mechanism 108 in the base unit 104.
More specifically, for example, the LED in an LED/optical sensor pair is configured for aligning with and illuminating an address bit configured on the non-electronic addressing mechanism 108 in the base unit 104, and the optical sensor in the LED/optical sensor pair is configured for determining whether light generated by the LED to illuminate the address bit is reflected back toward the optical sensor by the address bit. In an aspect, for example, the optical sensor may be configured to read an address bit of “1” if the amount of light reflected back is above a threshold, and to read an address bit of “0” if the amount of light reflected back is below a threshold, or vice versa. Further details of the operation of the optical address detection mechanism 106 are described below with reference to various non-limiting example aspects.
Referring to
Each slide-able button portion 202, when mounted onto the base portion 204, is slide-able between an “ON” position and an “OFF” position. In an aspect, for example, the “ON” position may represent an address bit of “1,” and the “OFF” position may represent an address bit of “0,” or vice versa. In some aspects, bumps and dents may be configured in the non-electronic switch array 200 to latch each slide-able button portion 202 into one of the two positions. The optical address detection mechanism 106 in the device head 102 includes an optical transmitter/receiver system configured to determine the status of each slide-able button portions 202 (e.g., whether each slide-able button portion 202 is in an “ON” position or in an “OFF” position). Each slide-able button portion 202 may represent a designated position in the non-electronic addressing mechanism 108 and is configurable into a first state having a first reflectivity level or a second state having a second reflectivity level. For example, each slide-able button portion 202, depending on whether configured in an “ON” position or an “OFF” position, either acts as a mirror/reflector and reflects light from an LED back to an associated optical sensor in the optical address detection mechanism 106, or deflects light so that the associated optical sensor in the optical address detection mechanism 106 does not detect any light (or only detects an insufficient amount of light).
For example, referring to
However, the present aspects are not so limited. For example, in some alternative aspects, the “ON” and “OFF” positions illustrated in
Referring to
The address pennant 402 in the base unit 104 includes multiple configurable positions 410 arranged as a knock-out array 416. Each configurable position 410 represents an address bit and is configurable into one of two states by either leaving a knock-out 412 in the configurable position 410 or by removing the knock-out 412 from the configurable position 410. Accordingly, each configurable position 410 is configurable into a first state having a first reflectivity level or a second state having a second reflectivity level. Each knock-out 412 is removable by breaking along corresponding perforations 414 configured in the address pennant 402. In one non-limiting aspect, before the address pennant 402 is configured for the first time, all of the knock-outs 412 in the knock-out array 416 are in place. Subsequently, an installer may knock out one or more of the knock-outs 412 to set a desired address in the address pennant 402. For example, in an aspect, each intact knock-out may represent an address bit of “1,” and each removed knock-out may represent an address bit of “0,” or vice versa. In an aspect, once inserted into the receiving portion 404 of the base unit 104 (e.g., a slot in the base unit 104), the knock-out array 416 is aligned over a cut-out 418 configured in the base unit 104 to allow for optical address detection as described below with reference to various example aspects in
In one non-limiting aspect, for example, referring to
Referring to
The address pennant 402 may be configured over an opening 510 of a cavity 502 (e.g., a hole) configured in the base unit 104. In some aspects, the opening 510 of the cavity 502 may be defined by the cut-out 418 described above with reference to
For example, in one non-limiting aspect, referring to
In another non-limiting aspect, for example, referring to
In another non-limiting aspect, for example, referring to
In some aspects, the cavity 502 may also be configured to prevent dust or other particles or environmental contaminants from getting through the base unit 104.
Although the above example aspects of the address pennant 402 are described with reference to the base unit 104 that includes the cavity 502, the present aspects are not so limited.
For example, in some alternative non-limiting aspects, the base unit 104 may not include the cavity 502, in which case the address pennant 402 may instead be configured over a non-reflective or substantially non-reflective surface (e.g., a black surface) on the base unit 104. For each knock-out in the address pennant 402, an LED in the optical address detection mechanism 106 may be configured to radiate light toward the position of the knock-out. The light is reflected back to an optical sensor in the optical address detection mechanism 106 by the knock-out when the knock-out is not removed. Alternatively, when a knock-out is removed, any light radiated by the LED toward the position of the knock-out passes through the hole left by the removed knock-out and is mostly absorbed by the black surface under the hole.
In yet another alternative non-limiting aspects, the address pennant 402 including the knock-out array 416 may have a non-reflective or substantially non-reflective surface (e.g., a black surface), and may be configured over a reflective surface (e.g., a white surface) on the base unit 104. For each knock-out in the address pennant 402, an LED in the optical address detection mechanism 106 may be configured to radiate light toward the position of the knock-out. If the knock-out is removed, the light is reflected back to an optical sensor in the optical address detection mechanism 106 by the reflective surface exposed through a hole left by the removed knock-out. If the knock-out is not removed, any light radiated by the LED toward the knock-out is mostly absorbed by the black surface of the knock-out.
Alternatively, in some aspects, the removable non-electronic addressing mechanism 108 in the base unit 104 may be implemented using a tag (e.g., a paper or plastic tag) including a row of boxes on which an address may be marked (e.g., using a black marker). In these aspects, the optical address detection mechanism 106 in the device head 102 may include an optical transmitter/receiver system configured to determine the status of each box on the tag (e.g., whether each box is marked or unmarked). For example, for each box on the tag, an LED in the optical address detection mechanism 106 may be configured to radiate light toward the box. The light is reflected back to an optical sensor in the optical address detection mechanism 106 by the box when the box is not marked, and is not reflected back to the optical sensor in the optical address detection mechanism 106 when the box is marked (e.g., the box is marked using a black marker and is therefore not reflective or minimally reflective).
In another alternative aspect, the removable non-electronic addressing mechanism 108 in the base unit 104 may be implemented using a tag including a row of white boxes covered with a peel-able layer, and the optical address detection mechanism 106 in the device head 102 may include an optical transmitter/receiver system configured to determine the status of each box on the tag (e.g., whether the peel-able layer on each box is peeled away or not). In an aspect, for example, the peel-able layer may be made of creased aluminum foil, and any light directed toward the creased aluminum foil is scattered away. For each box on the tag, an LED in the optical address detection mechanism 106 may be configured to radiate light toward the box. The light is reflected back to an optical sensor in the optical address detection mechanism 106 by the box when the peel-able layer on the box is peeled away, and is not reflected back to the optical sensor in the optical address detection mechanism 106 when the peel-able layer on the box is left thereon.
In yet another alternative aspect, the removable non-electronic addressing mechanism 108 in the base unit 104 may be implemented using a tag including a row of black boxes covered with a peel-able layer, and the optical address detection mechanism 106 in the device head 102 may include an optical transmitter/receiver system configured to determine the status of each box on the tag (e.g., whether the peel-able layer on each box is peeled away or not). In an aspect, for example, the peel-able layer may be made of smooth reflective aluminum foil. For each box on the tag, an LED in the optical address detection mechanism 106 may be configured to radiate light toward the box. The light is reflected back to an optical sensor in the optical address detection mechanism 106 by the smooth aluminum foil on the box when the smooth aluminum foil on the box is not peeled away and is left intact thereon. The light is absorbed by the black box and is not reflected back to the optical sensor in the optical address detection mechanism 106 when the aluminum foil on the box is peeled away.
In a further alternative aspect, the removable non-electronic addressing mechanism 108 in the base unit 104 may be implemented using a tag including a row of boxes that each can be covered by a sticker, and the optical address detection mechanism 106 in the device head 102 may include an optical transmitter/receiver system configured to determine the status of each box on the tag (e.g., whether or not the box is covered by a sticker). In an aspect, for example, the boxes may be white and the stickers may be black. For each box on the tag, an LED in the optical address detection mechanism 106 may be configured to radiate light toward the box. When the white box is not covered by a black sticker, the light is reflected back to an optical sensor in the optical address detection mechanism 106 by the white box. When the white box is covered by a black sticker, the light is absorbed by the black sticker and is not reflected back to the optical sensor in the optical address detection mechanism 106.
In another alternative aspect, the boxes may be black and the stickers may be white. For each box on the tag, an LED in the optical address detection mechanism 106 may be configured to radiate light toward the box. When the black box is covered by a white sticker, the light is reflected back to an optical sensor in the optical address detection mechanism 106 by the white sticker. When the black box is not covered by a white sticker, the light is absorbed by the black box and is not reflected back to the optical sensor in the optical address detection mechanism 106.
In some non-limiting aspects, the optical address detection mechanism 106 in the device head 102 may include an IR transmitter/receiver system. In these aspects, the removable non-electronic addressing mechanism 108 in the base unit 104 may include the address pennant 402 configured over the cavity 502 and including the knock-out array 416. Each knock-out 412 reflects IR radiation when the knock-out 412 is not removed. When the knock-out 412 is removed, the IR radiation passes through a hole left by the removed knock-out and gets dissipated within the cavity 502.
Alternatively, the removable non-electronic addressing mechanism 108 in the base unit 104 may include a white plastic tag with a row of boxes, where each box reflects IR radiation when the box is not marked, and does not reflect the IR radiation when the box is marked with black paint.
In another alternative aspect, an address detection mechanism in the device head 102 may include a sonar transmitter/receiver system, and the removable non-electronic addressing mechanism 108 in the base unit 104 may include the address pennant 402 configured over the cavity 502 and including the knock-out array 416. Each knock-out 412 reflects a received sonar signal when the knock-out 412 is not removed. When the knock-out 412 is removed, the sonar signal passes through a hole left by the removed knock-out and get dissipated within the cavity 502. For example, the interior surface of the cavity 502 may be covered with a soft rubber material that absorbs/diffuses any sonar signal that enters the cavity 502.
Alternatively, the removable non-electronic addressing mechanism 108 in the base unit 104 may include a tag with a row of boxes, where each box may have either a hard surface that reflects a received sonar signal, or a soft surface that absorbs a received sonar signal. For example, the tag may be made of rubber that absorbs a received sonar signal, in which case each box may be covered by a solid metal sticker to reflect a received sonar signal. Alternatively, the tag may be made of a solid metal that reflects a received sonar signal, in which case each box may be covered by a soft plastic sticker that absorbs a received sonar signal.
In another alternative aspect, an address detection mechanism in the device head 102 may include a radio-frequency (RF) transmitter/receiver system, and the removable non-electronic addressing mechanism 108 in the base unit 104 may include the address pennant 402 configured over the cavity 502 and including the knock-out array 416. Each knock-out 412 reflects a received RF signal when the knock-out 412 is not removed. When the knock-out 412 is removed, the RF signal passes through a hole left by the removed knock-out and get dissipated within the cavity 502. For example, the interior surface of the cavity 502 may be covered with an RF-absorbing material such as an RF-absorbing polymer or iron ball paint that absorbs RF signal that enters the cavity 502.
Alternatively, the removable non-electronic addressing mechanism 108 in the base unit 104 may include a tag with a row of boxes, where each box may have either a hard surface that reflects a received RF signal, or a soft surface that absorbs a received RF signal. For example, the tag may be made of an RF-absorbing polymer or may be covered with iron ball paint that absorbs a received RF signal, in which case each box may be covered by a solid metal sticker to reflect a received RF signal. Alternatively, the tag may be made of a solid metal that reflects a received RF signal, in which case each box may be covered by an RF-absorbing polymer sticker or by iron ball paint that absorbs a received RF signal.
In yet another alternative aspect, an address detection mechanism in the device head 102 may include an RF identification (RFID) system, and the removable non-electronic addressing mechanism 108 in the base unit 104 may include an address pennant. In one non-limiting aspect, for example, in order to configure an address for the addressable device 100, a removable RFID tag or sticker may be placed on the address pennant, and the address pennant may then be inserted into the base unit 104 of the addressable device 100.
The present aspects allow for a removable and configurable addressing mechanism (e.g., a removable and configurable address switch, pennant, tag, etc.) to be implemented as a common part that can be shipped to various job sites and can be configured/replaced in the field. In particular, for example, a removable and configurable address pennant or tag according to some present aspects provides a low cost addressing mechanism which does not require assembly and can be configured/replaced in the field. In an aspect, for example, the removable and configurable address pennant or tag can be quickly and readily configured/replaced in the field with minimal complexity.
Although the above aspects are described with reference to a binary detection mechanism (e.g., whether a switch is “ON” or “OFF,” whether a box is checked or not, etc.), the present aspects are not so limited. For example, in various alternative aspects, an address detection mechanism in a device head may be configured to detect which one of three or more states is configured for each address digit of the addressing mechanism in the base unit. For example, in one non-limiting aspect where the addressing mechanism is implemented using a tag including a row of mark-able boxes, the address detection mechanism in the device head may include an optical transmitter/receiver capable of detecting which one of a multitude of colors the box is marked with (e.g., whether the box is marked black, white, red, etc.).
In some aspects where the removable non-electronic addressing mechanism 108 in the base unit 104 includes the address pennant 402 including the knock-out array 416, each knock-out 412 may be removable by breaking along corresponding perforations 414 configured in the address pennant 402. For example, each knock-out 412 may be configured as a circular disk in the address pennant 402, where the circular disk has a perforated perimeter and is removable from the address pennant 402 by applying sufficient pressure to the circular disk to break the perforations 414. However, the present aspects are not so limited, and the address pennant 402 according to some alternative aspects may not include any removable knock-outs 412. Instead, each address pennant may be pre-configured with an address, in which case an installer may select an address pennant pre-configured with a certain address and then insert that address pennant into the base unit of a device.
The processor 602 may be a micro-controller and/or may include a single or multiple set of processors or multi-core processors. Moreover, the processor 602 may be implemented as an integrated processing system and/or a distributed processing system. The computing device 600 may further include a memory 604, such as for storing local versions of applications being executed by the processor 602, related instructions, parameters, etc. The memory 604 may include a type of memory usable by a computer, such as random access memory (RAM), read only memory (ROM), tapes, flash drives, magnetic discs, optical discs, volatile memory, non-volatile memory, and any combination thereof. Additionally, the processor 602 and the memory 604 may include and execute an operating system executing on the processor 602, one or more applications, display drivers, etc., and/or other components of the computing device 600.
Further, the computing device 600 may include a communications component 606 that provides for establishing and maintaining communications with one or more other devices, parties, entities, etc., utilizing hardware, software, and services. The communications component 606 may carry communications between components on the computing device 600, as well as between the computing device 600 and external devices, such as devices located across a communications network and/or devices serially or locally connected to the computing device 600. For example, the communications component 606 may include one or more buses, and may further include transmit chain components and receive chain components associated with a wireless or wired transmitter and receiver, respectively, operable for interfacing with external devices.
Additionally, the computing device 600 may include a data store 608, which can be any suitable combination of hardware and/or software, that provides for mass storage of information, databases, and programs. For example, the data store 608 may be or may include a data repository for applications and/or related parameters not currently being executed by the processor 602. In addition, the data store 608 may be a data repository for an operating system, application, display driver, etc., executing on the processor 602, and/or one or more other components of the computing device 600.
The computing device 600 may also include a user interface component 610 operable to receive inputs from a user of the computing device 600 and further operable to generate outputs for presentation to the user (e.g., via a display interface to a display device). The user interface component 610 may include one or more input devices, including but not limited to a keyboard, a number pad, a mouse, a touch-sensitive display, a navigation key, a function key, a microphone, a voice recognition component, or any other mechanism capable of receiving an input from a user, or any combination thereof. Further, the user interface component 610 may include one or more output devices, including but not limited to a display interface, a speaker, a haptic feedback mechanism, a printer, any other mechanism capable of presenting an output to a user, or any combination thereof.
