Silent Knight IDP-ISO Line Isolator Module

The Silent Knight IDP-ISO is an SLC loop line isolator module for Silent Knight IFP-series fire alarm control panels that helps protect the signaling line circuit from short circuits. It automatically opens when SLC loop voltage drops below four volts to isolate the affected section, allowing the remaining devices on the loop to continue operating normally. Key Specifications: Type: Line isolator module Core Function(s): Isolates short circuits on the SLC loop to protect the rest of the connected devices Loop/Protocol: SLC Power: 15 to 32 VDC operating voltage; 450 uA standby current when not isolating and relay is closed; 17 mA alarm current Indicators/UI: Panel-controlled status LED flashes green in normal condition and lights solid red in alarm Device Spacing: No more than 25 devices are recommended in each protected group 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 0.25 inches D Electrical: 40 Ohm SLC line loop resistance Environmental: 32 F to 120 F; 10% to 93% non-condensing Compatible Accessories: SMB500 - 4 inch square surface-mount electrical box System Compatibility: Silent Knight IFP-series fire alarm control panels that support IDP addressable modules
