Ajax FireProtect 2 SB (Heat) (8EU) white

Ajax FireProtect 2 SB (Heat) Jeweller is an Ajax wireless heat detector. It uses the following sensors: a temperature sensor (class A1R, EN 54-5) that alarms above 64 °C or when the temperature rises by more than 10 °C a minute.

The SB version has two built-in lithium batteries that last the detector's whole 10-year service life – no battery replacement is needed. The built-in sounder (85 dB at 3 m) signals the alarm immediately, and interconnected detectors raise the alarm in other rooms too. The front button tests the detector and silences the alarm, and an LED shows power and faults. The tamper switch reports removal; communication with the hub is over Jeweller radio at up to 1,700 m.
