The XG-HD020 Wireless Heat Detector is a highly reliable fire detection solution engineered for environments where traditional smoke alarms might trigger false positives — such as kitchens, garages, or high-dust areas. Instead of detecting smoke, it identifies rapid temperature rises, ensuring accurate fire risk warnings without unnecessary alarms. Built according to the BS5446-2 fire safety standard, the XG-HD020 provides trusted protection for both residential and commercial spaces. Equipped with a loud buzzer and bright LED indicator, it guarantees clear alerting even in noisy environments. The device is powered by a built-in non-replaceable 3V battery, delivering 10 years of maintenance-free operation and sending a low battery alert when reaching 2.7V. Operating over 433MHz wireless frequency, it integrates easily into existing alarm systems using the eV1527 protocol, making it a robust, smart choice for heat-based fire detection.
