The present disclosure relates generally to emergency equipment and devices including illuminated signs and emergency lighting units and particularly relates to emergency exit panels having multiple emergency functions in a single device.
Emergency lighting capability is mandated by building codes throughout most of the world for commercial buildings, schools and in some instance large residential homes. The most common type of emergency lighting is a so-called “Exit Sign” which is also the most noticed due not only to its ubiquity but also due to the fact that most exit signs are constantly illuminated and are therefore readily seen.
Exit signs are typically placed above doorways or on emergency exit routes to indicate (in a time of emergency) the most efficient or safe manner of exiting a particular building. Another common form of emergency lighting is generally referred to as an emergency lighting unit and typically operates two spaced lamps which are often referred to as “frog eyes”. Emergency lighting units operate only in the event of emergency and are intended to supply an acceptable degree of ambient illumination under emergency conditions, these conditions usually including loss of normal power.
Since emergency conditions requiring the most immediate and effective use of both exit signs and emergency lighting units are normally associated with main power loss, backup power is necessary for the continued operation of an exit sign and for start-up and continuing operation of an emergency lighting unit. These two forms of emergency lighting, the exit sign and the emergency lighting unit, are placed in a building structure at locations requiring a particular function of each form. Certain situations require the use of both forms of emergency lighting in one location. Rather than use separate lighting fixtures in one particular location, common practice has been to use a “combination” exit sign and emergency lighting unit, this type of fixture being commonly referred to as an exit/unit combo.
The “exit/unit combo” has previously taken the form of an emergency lighting unit mounted to an exit sign, the emergency lighting unit most often being mounted along the top of the exit sign. In most instances, the exit sign and the emergency unit operate separately although certain functions can be shared between the exit sign and the unit by providing common circuitry such as would be useful to detect power line failure for switching the exit sign to DC battery power and for initiating operation of the emergency lighting unit.
A particular exit/unit combo which has enjoyed substantial market acceptance is the QUANTUM Exit/Unit Combo manufactured by Lithonia Lighting, Inc. of Conyers, Ga., a wholly owned subsidiary of National Service Industries, Inc., of Atlanta, Ga., QUANTUM being a trademark of National Service Industries, Inc. The widespread use of the Lithonia Lighting combo has been brought about at least in part due to the reduced labor costs associated with installation of the Lithonia combo on site, the exit sign and the emergency lighting unit being factory assembled and pre-wired for shipment to a job site in a configuration allowing rapid and simultaneous final wiring of both the exit sign and the emergency lighting unit. Further, the Lithonia combo manufactured and marketed under the QUANTUM mark is comprised of a substantially all-plastic exit sign and a substantially all-plastic emergency lighting unit, thereby resulting in a combo product which is light in weight.
While the QUANTUM combo evidenced significant advantages in this art, it lacks many additional features which may be needed for emergency detection and/or required during an emergency condition. Accordingly, the art has experienced a long-felt and continuing need for improvement of a combination exit sign and emergency lighting unit or combo unit.

The emergency display panel 10 may be configured to include pre-recorded messages (e.g., programmed into PCB 60) which are automatically broadcast in case of emergency or selectively broadcast from the remote networking source 600 and/or an emergency response station 700. Moreover, the emergency display panel 10 and/or the display surface are made from a group of materials consisting of plastic construction materials, acrylic materials, metals, polypropylene, propylene and combinations thereof. The emergency display panel may be powered by AC 110 V/220 V circuitry with at least one battery backup, AC only or battery standalone systems.
In one particularly useful envisioned embodiment shown in
In the instance that the remote device is a smoke or heat detector, the secondary function may be to lock the exit door and/or provide a warning on the display surface 330. The remote device 340 may also be used to as a safeguard for assuring safe passage through a particular door or window in a building structure and may cooperate with the display surface 330 to sound or display an “ALL CLEAR” or “SAFE PASSAGE” message to escapees. The remote device 340 may also be utilized by fire or security safety personnel to facilitate or coordinate exit routing during an emergency situation.
As shown in
It is envisioned that the remote networking source 600, the emergency response station 700 and/or one or more emergency display panels 400a-400c may include an algorithm which configures each of the display surfaces 430a-430c with respective indicia 432a-432c or provides an audible warning relating to the hazardous condition. The indicia 432a-432c displayed on the respective display surfaces 430a-430c (or audible warning) may include information relating to a safe exit route, an alternate exit route, a hazardous condition, a warning, a caution, a prompt and/or combinations thereof. Directional indicators 459a, 459b and 459c may also be disposed on the housings 420a-420c and integrated into the control circuitry of the network (or each individual panel 400a-400c) to provide directional information (i.e., directional arrows) or status information (“caution”, “safe”, “okay”, etc.).
The panels 400a-400c may include wireless connections or be hardwired via electrical leads 610a, 610b and 610c to the remote networking source 600, the emergency response station 700 and/or other panels 400a-400c.
