Silent Knight SK-ISO Line Isolator Module

The Silent Knight SK-ISO is an SLC loop line isolator module for compatible Silent Knight 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, isolating the affected section so the remaining devices on the loop can continue operating. Key Specifications: Type: SLC line isolator module Core Function(s): Isolates short circuits on the SLC loop to help protect the rest of the connected devices Loop/Protocol: Silent Knight SLC Power: 15 to 32 VDC operating voltage; 450 uA maximum standby current when not isolating and relay is closed; 17 mA maximum current in isolation Indicators/UI: Panel-controlled status LED flashes green in normal condition and lights solid red in alarm Circuit Configuration: Automatically opens the SLC line during a short-circuit condition Addressing: Automatic isolation based on SLC loop voltage Device Spacing: No more than 25 devices recommended per 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 Environmental: 32 F to 120 F; 10% to 93% non-condensing Compatible Accessories: SMB500 - 4 inch square surface-mount electrical box System Compatibility: Compatible Silent Knight fire alarm control panels that support SK addressable modules
