## Summary description

HEIMAN HM-5HW is a wireless, battery-powered heat sensor alarm designed to detect rapid temperature rise or high temperatures indicative of fire. The device supports interlinking with compatible alarms for synchronized alerts, enabling whole-property notification. Ideal for homes, apartments and small businesses, it provides standalone heat detection without relying on smoke sensing and simplifies installation where smoke detectors are unsuitable.

## Long description

Heiman HM-5HW Interlinked Wireless Heat Detector Alarm is a wireless heat sensor designed to detect rapid temperature rises and provide audible warning. The device activates an 85 dB alarm and a red LED indicator when the measured temperature exceeds the static response threshold. It operates across a wide temperature range and can be linked with multiple units to form a combined alarm network suitable for homes, hotels, offices and industrial premises.
Advantages
The HM-5HW supports wireless interconnection with up to 40 other alarms, ensuring that when one unit detects heat, all linked sensors sound simultaneously. Its heat-based detection makes it suitable for environments where smoke detectors may underperform, such as kitchens, boiler rooms and garages. The housing is made of durable ABS material with resistance to moisture and corrosion, and the unit features simple radio-based installation without complex wiring. The alarm can be silenced via remote control for user convenience.

How to use

The sensor monitors ambient temperature and triggers the alarm and LED indicator when the response threshold (54–65°C) is exceeded. Use the remote control to silence the audible alarm temporarily when needed, following safety procedures before resetting the device.
Recommendations
Install the HM-5HW where rapid temperature rises are most likely to occur but avoid placing it too close to direct heat sources. Regularly test the unit and replace batteries as recommended in the manual. For full-area protection in larger buildings, connect multiple HM-5HW units (up to 40) to ensure simultaneous notification across all zones.
