ABSTRACT:
A manually actuatable integrated contact module connecting to an output access module by means of a common communications link. The integrated contact module has an electrical contact, a logic circuit, a communications circuit and a communications terminal mounted on a common printed circuit board. The printed circuit board provides communication between the electrical contact and the logic circuit, between the logic circuit and the communications circuit, and between the communications circuit and the communications terminal. The printed circuit board is enclosed within a protective housing. A contact operator is slidably mounted with respect to the printed circuit board such that it is partially enclosed within the housing and movable between a first position and a second position. An operator interface device in mounted on one side of a control panel and the integrated contact module is attached to the operator interface device an the opposite side of the control panel such that the operator interface device is in communication with that portion of the contact operator outside the protective housing. The contact operator, in response to movement of the operator interface device, causes the contact to change state thereby initiating a signal to be processed by the logic circuit and communications circuit prior to being placed on the common communications link.
