Silent Knight Fire Alarm Panels and Devices
Silent Knight is Honeywell's fire alarm line for small and mid-sized commercial buildings, installed widely by fire and security contractors across the US. The range runs from addressable and conventional control panels through SLC loop expanders, intelligent power supplies, digital and cellular communicators and LCD remote annunciators to the field devices themselves.
The field devices include photoelectric and combination smoke and carbon monoxide detectors, heat detectors, duct smoke detectors, monitor, relay and addressable control modules, single and dual action pull stations, and detector bases with relay or sounder options. Cabinet keys and break rods are here too.
Silent Knight panels stay in service for decades, so we also keep discontinued and superseded parts for older installations that are not being replaced. If the Silent Knight part you need is not listed, request it on our quote page.
