Silent Knight IFP-300BD (Replacement Electronics Assembly, Main Board)

The IFP-300BD is the replacement electronics assembly for Silent Knight IFP-300 series control panels. This field-replaceable main board restores full functionality to existing IFP-300 or IFP-300B cabinets. When installed, it provides one SLC supporting up to 159 IDP/SK detectors and 159 IDP/SK modules per loop, or 127 SD devices per loop. System capacity is up to 300 addressable points with IDP/SK devices or 254 points with SD devices. Four Flexput circuits can be configured as NAC outputs or auxiliary power. Series features remain available, including JumpStart auto programming, drift compensation with maintenance alerts, a 4×40 LCD, and networking for up to 32 panels via SK-NIC with copper or fiber options.
