The Edwards EST SIGA-CC1 intelligent addressable single input signal module switches a supervised Class B riser for 24 Vdc notification appliances, 25 or 70 VRMS audio evacuation speakers, or firefighter telephones under command of a Signature loop controller. It supports selectable personality codes for signal power, audio, or telephone-with-ring-tone applications, supervises the output wiring for faults, and mounts directly to standard 2-gang or 4-inch square boxes using Signature mounting plates.
