Product Code: SK-ZONE


The SK-Zone is an intelligent two-wire interface module for use with Silent Knight IntelliKnight series fire alarm control panels (FACPs). The SK-Zone allows a Silent Knight FACP to interface and monitor two-wire conventional smoke detectors. The SK-Zone is addressed through the signaling line circuit loop of the FACP. It transmits the status of one full zone of two-wire detectors to the FACP. Status conditions are reported as normal, open, or alarm. The SK-Zone supervises the zone of detectors and the connection of the external power supply. All two-wire detectors being monitored must be UL compatible with the SK-Zone.
