The Ajax FireProtect 2 RB is a next-gen heat detector designed for residential fire safety. With two thermistors, the detector quickly reacts to the synthetic materials burning and notifies about danger with a built-in powerful siren and critical alerts from Ajax apps. Thought-out design, mounting, and in-app settings make installation straightforward and quick. Everything meets the most modern fire safety standards.FireProtect 2 is equipped with two A1R-class thermistors to detect smokeless fire threats. They give a significant advantage in detecting a rapid temperature rise when synthetic materials burn, or a fire starts from smoldering. Thermistors are located outside the enclosure to eliminate life-saving detection delays. So FireProtect 2 is ready to detect a fire as fast as possible, even if it starts imperceptibly.Features:-An interconnected alarm of all fire detectors at the facility in 20 seconds-Built-in siren with a volume of 85 dB at a distance of 3 meters-Ability to operate autonomously without an Ajax hub-10 years of operation with sealed batteries, and up to 7 years — with replaceable batteries-SmartBracket mounting panel with the ability to align the detector after installation-Remote control and configuring via Ajax app-Pairing with the Ajax hub via QR code-Two built-in thermistors-Monitoring with PRO Desktop
