CTX-95

The Gamewell-FCI City Tie Expander (CTX-95) is a singlecircuit, reverse-polarity transmitter that provides the interface between the Fire Alarm Control Panel (FACP) and a municipal system or central station. The CTX-95 connects to the panel via a three-wire SLC circuit. The most common usage is transmitting supervisory signals and their faults on a separate city tie from the main system, and to transmit alarms to a central station to indicate building alarm or arrival entrance to building.

The CTX-95 is either surface or flush mounted and has an integral LED that lights at device activation.
