GSA-CC1/MCC1 Single Input Signal Modules and GSA-CC2/ MCC2 Dual Input Signal Modules are part of Kidde's Signature Series system. They are intelligent analog addressable devices used for connecting, upon command from the loop controller, supervised Class B signal or telephone circuits to their respective power inputs. The power inputs may be polarized 24 Vdc to operate audible and visible signal appliances or 25 and 70 VRMS to operate audio evacuation speakers and firefighter’s telephones.

The actual operation of the GSA-CC1/MCC1 and GSA-CC2/ MCC2 is determined by the “personality code” selected by the installer. It is downloaded to the module from the Signature loop controller during system configuration.

The GSA-CC1 and GSA-CC2 mount to standard North American two-gang electrical boxes, making them ideal for locations where only one module is required. Separate I/O and data loop connections are made to each module.

The GSA-MCC1 and GSA-MCC2 are part of the UIO family of plug-in Signature Series modules. They function identically to the GSA-CC1 and GSA-CC2, but take advantage of the modular flexibility and easy installation that characterize all UIO modules. Two- and six-module UIO motherboards are available. These can accommodate individual risers for each on-board module, or risers that are shared by any combination of its UIO modules. All wiring connections are made to terminal blocks on the motherboard. UIO assemblies may be mounted in Kidde enclosures.
