Silent Knight IDP-ZONE Two-Wire Interface Module

The Silent Knight IDP-ZONE is an addressable two-wire interface module for Silent Knight IFP-series fire alarm control panels that converts a conventional two-wire detector zone to the SLC loop. It supervises one full zone of compatible two-wire smoke detectors, reports normal, open, or alarm status to the panel, and also supervises the detector circuit and external power supply. Key Specifications: Type: Addressable two-wire interface module Core Function(s): Interfaces and monitors one zone of compatible two-wire conventional smoke detectors Loop/Protocol: SLC Power: 15 to 32 VDC operating voltage; external power supply current 90 mA per module in alarm; 12 mA nominal standby current at 24 VDC; 300 uA maximum SLC standby and alarm current at 24 VDC with LED enabled Indicators/UI: Panel-controlled status LED flashes green in normal condition and lights solid red in alarm Circuit Configuration: Supports Style B and Style D wiring Addressing: Rotary address switches for fast installation Electrical: 3.9K Ohm end-of-line resistance; 40 Ohm SLC loop impedance; 25 Ohms maximum initiating device circuit wiring resistance Mounting: Mounts to a standard 4 inch square electrical box with a minimum depth of 2-1/8 inches Physical: 4.5 inches H x 4 inches W x 1.25 inches D Environmental: 32 F to 120 F; 10% to 93% non-condensing System Compatibility: Silent Knight IFP-series fire alarm control panels that support IDP addressable modules
