ABSTRACT:
An exit device includes an electroluminescent exit sign assembly, preferably mounted on a push rail actuator of the exit device. An electroluminescent illuminator, an opaque material and a transparent protective cover form the electroluminescent sign assembly. The push rail actuator operates a latch mechanism and opens an associated exit door when pressure is applied. An inverter may be located within the exit device to power the electroluminescent illuminator with an AC or voltage. The electroluminescent sign assembly is preferably removable for repair or replacement without removing the exit device from the exit door and is located within a surface cavity in an electrically insulating touchpad on the exit device actuator. Additional transparent nonconductive material surrounds the electroluminescent material to provide further electrical insulation.
