Ajax FireProtect 2 RB (Heat/Smoke/CO) is a wireless fire detector with three sensors: a dual-spectrum optical smoke sensor, a temperature sensor and a carbon monoxide (CO) sensor. Three hazards in one device means one detector on the ceiling instead of the previous two or three.
The smoke sensor judges the size of air particles and does not react to water vapour, and the patented smoke chamber protects it from dust, dirt and insects. The temperature sensor raises an alarm when the room exceeds 64 °C or when the temperature rises by more than 10 °C in a minute. The CO sensor tracks the accumulated dose of carbon monoxide and alarms when it exceeds the permitted limit.
The built-in 85 dB sounder signals the alarm immediately, and interconnected detectors pass the alarm on to other rooms. The detector can be tested with the button on the front panel, an LED shows power and state, and the tamper reports removal. The batteries are replaceable and last up to 7 years; the detector's service life is 10 years.
