The inputs on the SK-ZONE-6 share a common FACP signaling line circuit (SLC) input, and the initiating device circuits share a common external power supply. Otherwise, each input on the module operates independently from the others. If needed, you can disable a maximum of two unused inputs on the SK-ZONE-6 board. It transmits the status of a zone of two-wire detectors to the FACP. Status conditions are reported as normal, open, or alarm. The SK-ZONE-6 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-6 Interface Module Main Features Converts a conventional two-wire loop to an SLC loop Six zone inputs Fully supervised Support for Class B and Class A wiring Removable 12 to 18 AWG plug-in terminal blocks Individual LED for each relay contact Two module mounting in the IDP-ACB cabinet Up to two unused modules can be disabled Rotary address switches for fast installation Mounting hardware included UL Listed
