The Ajax FireProtect is a wireless smoke and temperature detector designed for indoor safety. It uses a photoelectric sensing element with an infrared emitter and photodetector to identify smoke, while integrated temperature sensors trigger an alarm if the heat reaches +59°С ±2°С. When a threat is detected, the device alerts you via a light indicator and a built-in siren with a volume of 85 dB, delivering the signal in just 0.15 seconds. To prevent unnecessary disruptions, it includes a false alarm filter. This black, compact device measures 132 × 132 × 31 mm and weighs 220 g. It is powered by two CR2 batteries and a CR2032 backup, providing a service life of up to 3 to 4 years. For those using Ajax hubs, range extenders, or bridges, the detector can communicate over distances up to 2000 meters in direct visibility and supports interconnected alarms. A built-in tamper button ensures you are notified if the unit is opened or removed from its mounting. Installation is straightforward using the included SmartBracket and mounting kit. It operates reliably in environments with temperatures between 0°С and +65°С and humidity levels up to 80%, making it a dependable choice for homeowners who want a connected fire safety system that integrates seamlessly with their security hub.
