## Summary description

The Reliable Performance HD 912-4 is a fixed-temperature heat detector designed to respond when ambient temperature reaches its set activation threshold. As a stand-alone heat sensor it is suitable for environments where smoke detectors are impractical. Typical uses include kitchens, boiler rooms and garages. The detector provides reliable thermal detection for fire alarm systems and helps trigger alerts or control circuits to improve safety.

## Long description

The Reliable Performance HD 912-4 is a fixed-temperature heat detector engineered to trigger an alert when the ambient temperature reaches a predefined activation threshold. Designed as a stand-alone heat sensor, it is intended for locations where smoke-based detection is not suitable or may give false alarms. Typical installations include kitchens, boiler rooms, garages and other environments with dust, fumes or steam. The device supports fire safety systems by providing dependable thermal detection and initiating alerts or control actions when the set temperature is exceeded.
Advantages
The HD 912-4 offers stable detection based on a fixed temperature point, reducing nuisance alarms caused by transient smoke or dust. Its stand-alone design simplifies installation in challenging environments where smoke detectors underperform. The detector’s construction is optimized for consistent thermal response and long-term reliability, enabling integration with existing fire alarm circuits or simple local control systems. The unit requires minimal maintenance compared with more complex sensing technologies.
Suitable for
 Kitchens and commercial cooking areas where smoke detectors may trigger false alarms
 Boiler rooms and mechanical spaces with high heat or airborne particulates
 Garages, workshops and storage facilities with vehicle exhaust or dust
 Industrial or utility areas where thermal detection is preferred over smoke sensing
Key specifications
 Detection principle: fixed-temperature heat sensing
 Activation: responds when ambient temperature reaches the preset threshold
 Mounting: ceiling or wall mount compatible with standard detector bases
 Environmental suitability: intended for areas with dust, fumes or steam where smoke detectors are impractical
 Output: signaling contact or compatible interface for fire alarm/control circuits
 Maintenance: low maintenance design with periodic visual inspection recommended
How to use
Install the HD 912-4 on a ceiling or wall according to local codes and the mounting instructions provided by your fire safety system supplier. Position the detector away from direct heat sources such as ovens, furnaces or ventilation outlets that could cause false activation. Connect the detector output to the control panel or local alarm circuit following standard wiring practices. After installation, verify operation by following the test procedure specified for fixed-temperature detectors and record the result. Perform routine visual inspections and functional checks at intervals required by applicable regulations.
Usage recommendations
Use the HD 912-4 in locations where thermal rise indicates a fire risk and smoke detection is unreliable. Combine with other types of detectors in mixed-technology fire protection schemes for comprehensive coverage. Follow local fire safety codes for spacing, placement and periodic testing to ensure continued reliable operation.
