DC 9V Battery (HD-505) Standalone Heat Detector

The HD-505 Standalone Heat Detector is powered by a 9V battery, providing an energy-efficient solution for heat detection. With a static current of less than 50μA and an alarm current of up to 30mA, this device ensures reliable and efficient operation. The detector is designed to trigger an alarm when temperatures reach 57℃, emitting a loud alarm sound of ≥85dB at 1 meter. The alarm is further enhanced with a flashing LED for visual indication. Suitable for use in environments with humidity levels up to 95% RH (non-condensing), the HD-505 operates effectively within a temperature range of -10℃ to +50℃. It complies with EN54-5 standards and has dimensions of 105mm in diameter and 53mm in height. The heat detector can be easily installed via ceiling mount and offers an optional RF signal output at 433.92MHz for enhanced monitoring and connectivity.
