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

Ajax FireProtect 2 SB (CO) Jeweller is an Ajax wireless carbon monoxide detector. It uses the following sensors: a chemical carbon monoxide (CO) sensor that tracks the accumulated dose: above 50 ppm it alarms within 90 minutes, above 100 ppm within 40 minutes and above 300 ppm within 3 minutes.

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.
