The Silent Knight SK-HEAT is a commercial thermal detector designed for compatible Honeywell Silent Knight fire alarm control panels. It uses a thermistor-based sensing circuit to provide reliable fixed-temperature detection and initiates an alarm when the surrounding temperature reaches 135°F (57°C).
The detector provides individual device identification, continuous panel supervision, rotary address selection, and visible status indication. Its plug-in construction simplifies installation, inspection, testing, and replacement. This product is intended exclusively for commercial fire alarm installations.
The SK-HEAT operates on a compatible Silent Knight signaling line circuit with an operating voltage range of 15 to 32 VDC. Rotary decimal switches allow technicians to assign an individual device address directly at the detector.
The fire alarm control panel continuously monitors detector communication and operating status. A compatible mounting base is required and may be sold separately.
The Silent Knight SK-HEAT installs on a compatible plug-in detector base. Field wiring terminates at the base, allowing the detector head to be removed for testing, inspection, or replacement without disturbing the installed wiring.
The detector is designed for ceiling or wall installation where permitted by applicable codes, approved system documentation, and project requirements.
Suitable for:
Compatible with selected:
Always verify control-panel protocol, detector-base compatibility, firmware requirements, and approved system documentation before installation.
