Silent Knight sk-heat-w Addressable Heat Detector 135F

Product Description

The SILENT KNIGHT sk-heat-w is an addressable heat detector with an integrated base, designed for use in fire alarm systems that require precise, fast-response thermal sensing. It uses a thermistor sensing circuit to monitor ambient temperature and triggers a fixed-temperature alarm at 135 degrees F. This detector is an addressable device, meaning it communicates individual status and alarm data back to a compatible fire alarm control panel. Licensed fire alarm technicians and low-voltage contractors are the primary installers of this device.

The sk-heat-w is suited for residential and commercial applications where smoke detectors are not appropriate, such as kitchens, garages, attics, and other environments with dust, steam, or combustion byproducts. The fixed-temperature thermistor design provides a reliable trigger point without requiring rate-of-rise compensation, making it straightforward to apply in spaces with predictable ambient temperature ranges below the alarm threshold.

Key Features

• Addressable design reports individual device status to the fire alarm control panel
• Thermistor sensing circuit enables fast thermal response
• Fixed-temperature alarm point at 135 degrees F
• Integrated base included, simplifying installation and wiring
• Suitable for environments where smoke detection is not practical

Compatibility

Designed as an OEM-style addressable heat detector for use with compatible SILENT KNIGHT addressable fire alarm control panels and loops. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation must be performed by a licensed fire alarm technician or low-voltage contractor in accordance with NFPA 72 and applicable local codes. Disconnect and lock out power to the fire alarm control panel loop before wiring or removing any addressable device. Verify the device address is set correctly per the system design drawings before restoring power. Do not install in areas where ambient temperatures regularly approach or exceed the 135 degrees F alarm threshold.
