Ajax FireProtect 2 RB HS

The smoke detection system uses optical sensors with infrared LEDs. The LEDs emit light with different wavelengths, which allows the detector to determine the size of the volatile particles and react only to smoke. The optical system is designed so that non-volatile particles or insects cannot be in two beams simultaneously and cause a false alarm. FireProtect 2 (Heat/Smoke) also detects a rapid temperature rise with two built-in thermistors that are located outside the detector for faster threat detection. If the room temperature exceeds 64 °C or increases at more than 10 °C per minute, the detector recognizes this as a rapid temperature rise and raises the alarm. The temperature alarm can trigger even if there is no smoke in the room.
