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.
What we stock here:
- Silent Knight smoke detectors - photoelectric, combination smoke and carbon monoxide, and heads with remote test capability
- Heat detectors, including fixed temperature and rate of rise types
- Duct smoke detectors and replacement duct housing covers
- Monitor, mini monitor, relay and addressable control modules
- Single and dual action pull stations, break rods and cabinet keys
- Detector bases, including relay and sounder bases
Silent Knight panels stay in service for decades, so we also keep discontinued and superseded parts for older installations that are not being replaced.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.
