Silent Knight SK-HEAT-W Addressable 2-Wire Fixed Heat Detector

Product Overview

The Silent Knight SK-HEAT-W Addressable 2-Wire Fixed Heat Detector is an intelligent, addressable heat detector designed for reliable thermal detection in commercial fire alarm systems. Factory preset to 135°F (57°C), this fixed-temperature detector provides effective property protection in applications where heat detection is preferred or where smoke detection may not be suitable.

The SK-HEAT-W uses a two-wire Signaling Line Circuit (SLC) connection and supports device-level addressability through rotary decimal switches. This allows individual detectors to be identified by their specific address and location within a compatible Silent Knight fire alarm system.

The detector features advanced thermal technology for fast response and a contemporary design suitable for modern fire detection installations. Its built-in LED indicators blink each time the detector is polled, providing a visible indication of communication with the fire alarm control panel.

The SK-HEAT-W is a direct replacement for the previous SK-HEAT heat detector and is supplied with a 6-inch mounting base and trim ring, providing the components needed for installation as specified.

The SK-HEAT series is available in multiple thermal configurations, including fixed-temperature, rate-of-rise, and high-temperature models. The SK-HEAT-W specifically is the fixed-temperature version with a factory preset of 135°F (57°C).

Fixed-Temperature Heat Detection

The SK-HEAT-W is designed to activate at a fixed temperature of 135°F (57°C). Its thermal sensing technology provides heat detection for applications where fixed-temperature detection is appropriate.

The SK-HEAT series also includes other thermal configurations, such as the SK-HEAT-ROR-W rate-of-rise model and SK-HEAT-HT-W high-temperature model. These models should not be confused with the SK-HEAT-W fixed-temperature detector.

Addressable Fire Alarm Integration

The Silent Knight SK-HEAT-W communicates through a two-wire SLC connection and provides individual device addressing using rotary decimal switches. Device addressing allows the fire alarm system to identify the specific detector reporting an alarm or status condition.

The LED indicator blinks whenever the unit is polled, providing a visual indication of communication with the system.

Direct Replacement for SK-HEAT

The SK-HEAT-W is specified as a direct replacement for the Silent Knight SK-HEAT heat detector. Its addressable design and supplied mounting components make it suitable for replacement and new installation applications where the SK-HEAT-W specifications are appropriate.
