The Ajax FireProtect 2 RB is a comprehensive safety device designed to protect indoor spaces by detecting heat and smoke. It utilizes a double-spectrum optical smoke sensor that distinguishes smoke particles from water vapor, while a patented smoke chamber prevents dust and insects from triggering false alarms. For thermal threats, the detector triggers an alarm if temperatures exceed 64°C or if there is a sudden spike of more than 10°C within a single minute. Communication is handled via the proprietary Jeweller wireless technology, providing a range of up to 1,700 meters in open spaces through encrypted two-way signals. If a fire is detected, the built-in 85 dB siren sounds immediately, and the device can notify other detectors via the hub within 20 seconds or directly between units within a minute as a fallback. The unit is powered by two pre-installed CR123A batteries that can last up to 7 years, reducing the need for frequent maintenance. Measuring 124 x 124 x 45 mm and weighing 274.5 g, the detector comes in white or black finishes to match your interior. It includes a SmartBracket mounting panel that allows you to adjust the position during installation for a precise fit. To ensure reliability, the system includes anti-sabotage features that alert you if the device is removed or if communication is lost for more than 15 minutes.
