In the illustrated example, the mounting plate 12 (
The illustrated terminal clip 14 (
In the illustrated example, the notification device accepting portion 42 of the terminal clip 14 includes a slot 58 for accepting a portion of a circuit board 60 extending from the notification device 16 when the notification device 16 is connected to the terminal clip 14 and the mounting plate 12. The slot 58 includes five contacts 62 electrically connected to the five screw receivers 50. Therefore, when the notification device 16 is connected to the terminal clip 14 and the mounting plate 12, the notification device 16 will have five connections 51 with the wiring (five of them) through the contacts 62 in the slot 58 and the screw receivers 50. As illustrated in
The illustrated notification device 16 includes at least one notification member 18 for notifying people adjacent the evacuation appliance 10 of an evacuation situation. For example, the evacuation situation could be a fire in the building. The at least one notification member 18 can include an audible notification, a visual notification or a combination of the audible and visual notification. The notification device 16 includes a housing 66 having the at least one notification member 18 therein. The housing 66 preferably includes a top wall 68, a bottom wall 70, a first side wall 72, a second side wall 74 and a front face 76. The front face 76 preferably includes a plurality of slots 78 for allowing an audible notification from the at least one notification member 18 that emits the audible notification to exit the notification device 16 easily. The front face 76 also preferably includes a light 80 located behind a front transparent or translucent shield 82. The first side wall 72 includes a slide member 84 for selecting a candela of the at least one notification member 18 that emits light. The second side wall 74 includes the circuit board 60 extending therefrom and a sound selection device 86.
In the illustrated example, the notification device 16 is slid onto the mounting plate 12 to connect the notification device 16 to the mounting plate 12. The top wall 68 and the bottom wall 70 of the notification device 16 each include a pair of connection flanges 88 extending upward and downward, respectively. In order to connect the notification device 16 to the mounting plate 12, the notification device 16 is positioned on the base 21 of the mounting plate, with the connection flanges 88 positioned to the left of the upper flanges 32 and the lower flanges 34 of the base 21. The notification device 16 is then slid to the right, thereby moving the connection flanges 88 of the notification device 16 under the upper flanges 32 and the lower flanges of the base 21. The connection flanges 88 preferably include a nub on a top thereof configured to abut a bottom of the upper flanges 32 and lower flanges 34 to frictionally connect the notification device 16 to the mounting plate 12. Furthermore, as the notification device 16 is slid to the right, the circuit board 60 will slide into the slot 58 of the terminal clip 14. The circuit board 60 includes five traces on a bottom surface thereof to electrically connect the notification device 16 to the five connections as discussed above. When the notification device 16 is fully connected to the mounting plate 12, a fastener can be inserted through an opening in the front face 76 of the notification device 16 and into the device opening 38 of the ect the mounting plate 12 to a wall. e a plurality of wall connection openings 36 configured to accept fasteners lower panel 30 of the base 21 of the mounting plate 12 to securely connect the notification device 16 to the mounting plate 12.
The illustrated at least one notification member 18 of the notification device 16 that emits an audible signal is preferably adjustable to select any one of a number of audible signals using the sound selection device 86 (
As can be seen from the above chart, the whoop sound preferably does not have either a continuous or interrupted selection as the sound only has one selection.
In the illustrated example, the visual notification of the at least one notification member 18 of the notification device 16 includes activation of the light 80. Preferably, the light 80 is a strobe light. Furthermore, the light 80 preferably emits a selected one of 15, 30, 60, 75 and 110 candella. However, it is contemplated that the light could be continuous or could emit light at any number of intensities. The illustrated slide member 84 is slid to select one of the desired intensities. The slide member 84 includes the intensities written on a top thereof that are visible from a front of the notification device 16 without removing the notification device 16 from the mounting plate 12. The slide member 84 is slid to align the intensity with a prong 100 on the housing to select that intensity. The slide member 84 preferably includes a depressible tab 102 that has to be depressed to allow the slide member 84 to slide. The tab 102 includes a projection that fits into recesses on a slide member base 108 located below and to a side of the slide member 84. Therefore, the tab 102 has to be depressed to move the slide member 84.
The illustrated slide member 84 preferably includes a hole 104 configured to accept a pin 106 therein for locking the slide member 84 in a selected position. A slide member base 108 located below the slide member 84 preferably includes a plurality of apertures 110 configured to be aligned with the hole 104 in the slide member 84. During use, the intensity is selected using the slide member 84. Thereafter, the pin 106 is inserted into the hole 104 and into one of the apertures 110 to lock the slide member 84 in position. In order to change the intensity of the light 80, the pin 106 must first be removed from the hole 104 and the associated aperture 110. This is done by pressing the pin 106 through the hole 104 and the associated aperture 110 and through the bottom of the slide member base 108. However, when the notification device 16 is connected to the mounting plate 12, the pin 106 will abut against a top of the mounting plate 12. Therefore, the pin 106 can only be removed by first removing the notification device 16 from the mounting plate 12 for security.
The illustrated evacuation device 10 can also include a bezel 200 that snaps over the mounting bracket 12 and the notification device 16. The bezel 200 includes a side wall 202 and a front opening 204. The notification device 16 is configured to extend through the front opening 204 when the bezel 200 is connected to the mounting plate 12. The side wall 202 of the bezel 200 includes a plurality of tabs that snap under the mounting plate 12 to connect the bezel 200 to the mounting plate 12.
In the illustrated embodiment, the terminal clip 14 includes the test nodes 300 for testing the evacuation device 10. The test nodes 300 are configured to be contacted by a test lead 302 in order to ensure that all of the five connections are properly connected. The test leads 302 measure a voltage across the notification device 16. Since the test nodes 300 are exposed when the notification device 16 is connected to the mounting plate 12, the evacuation device 10 can be tested without removing the notification device 16 from the mounting plate 12. Therefore, the evacuation device 10 can be tested after it is installed by only removing the bezel 200 or before the bezel 200 is connected to the mounting plate 12. Furthermore, the evacuation device 10 can be tested easily to determine which device in a series of devices is not working properly without taking each evacuation device 10 apart. Therefore, the evacuation device 10 can be easily tested in a non-intrusive manner. Accordingly, there is no need to remove the notification device 16 from the mounting plate 12, the wiring to the evacuation appliance 10 and a source for signaling the evacuation appliance 10 in order to gain access to the terminals as there is provided a hole or series of holes having the node or nodes 300 therein through which testing could be performed using test leads 302. Furthermore, one of the evacuation appliances 10 in a series of evacuation appliances can be deliberately short circuited to check the source for signaling the evacuation appliance 10 to ensure the source is working correctly. However, the test nodes 300 are preferably used during installation to demonstrate that the installation has been completely correctly or to locate wiring issues.
Another embodiment of the present invention provides the test nodes 300 accessible outside of the side wall of the bezel 200 but still concealed by a protective outside housing. This would be used in a situation where aesthetics are significant as there would be no holes or access ports on the exterior of the device. Additionally, it is contemplated that the printed circuit board can be directly accessed via holes in the housing of the notification device or a tab coming through the housing. Furthermore, it is contemplated that the evacuation device 10 could have a system wherein the evacuation device 10 could be tested remotely by using a signal. For example, the evacuation device 10 could be tested by sending a radio or Bluetooth signal to the evacuation device 10.
It is to be understood that variations and modifications can be made on the aforementioned structure without departing from the concepts of the present invention, and further it is to be understood that such concepts are intended to be covered by the following claims unless these claims by their language expressly state otherwise.
