A push plate assembly sends a signal to a receiver. The push plate includes a housing, a push plate, a signal generator, a biasing member, a first latch element, a second latch element, and a button. The push plate is movably mounted to the housing. The signal generator includes a switch. The switch is in electrical communication with circuitry through which a signal is transmitted. The biasing member is disposed between the push plate and the signal generator. The biasing member biases the push plate away from the signal generator. The first latch element is connected to the push plate. The second latch element is disposed in the housing. The first latch element and the second latch element engage with one another to limit the movement of the push plate away from the signal generator as the biasing member acts on the push plate. At least one of the first latch element and the second latch element is accessible from outside of the housing by an associated hand tool such that the hand tool can contact at least one of the first latch element and the second latch element to disengage the first latch element from the second latch element so that the push plate can be selectively removed from the housing. The button is interposed between the push plate and the signal generator. The button is disposed in relation to the push plate and the switch so that when a force is applied to the push plate moving the push plate towards the signal generator, the push plate contacts the at least one button to activate the switch.
