SIGA-CC2A and SIGA-MCC2A Single/Dual Input Signal Modules are part of Edwards’ Signature Series system. They are intelligent analog addressable devices used for connecting, upon command from the loop controller, supervised Class A or Class B signal or telephone circuits to their respective power inputs.

Module power inputs may carry polarized 24 Vdc current to operate audible and visible signal appliances, or 25 and 70 VRMS to operate audio evacuation speakers and firefighter’s telephones. The SIGA-CC2A/MCC2A may be configured as a three-state or four-state telephone riser selector.
