AJAX 52253 FireProtect 2 RB Wireless Smoke/Heat/CO Detector Black Jeweller 85dB Siren 5yr Battery IP20 124x124x45mm

Ajax FireProtect Wireless Fire Detector - Black (4823114030703)

The Ajax FireProtect 52253 is a professional-grade wireless fire security detector designed for 24/7 monitoring of residential and commercial premises. This high-precision device features a dual-detection system that combines a photoelectric smoke sensor with a sensitive thermistor for heat detection. It triggers an alarm immediately upon detecting smoke or if the ambient temperature reaches 60°C, as well as during rapid temperature spikes (rate-of-rise). Finished in a sleek black housing, the unit operates as part of the Ajax security system via the Jeweller radio protocol, maintaining a secure connection at a range of up to 1,300 meters from the hub. The detector is equipped with an integrated 85dB siren for local alerts and can operate completely independently of a central hub if necessary. It features a built-in battery with a lifespan of up to 4 years and provides automated self-testing and low-battery notifications via the Ajax mobile application.
