## Long description

The Ajax FireProtect 2 RB is a compact heat and smoke alarm designed for residential fire safety. It combines a carbon monoxide sensor, a powerful built-in siren and wireless connection to the Ajax ecosystem. The detector supports long battery life, real-time data exchange with a hub, and an intelligent alarm analysis system to reduce false alarms. Available in versions with different battery options and offering up to 1,700 m radio range in open space, the device is suitable for a wide range of home installations.
Advantages
FireProtect 2 provides stable performance for years thanks to advanced hardware and software engineering and efficient power management. The detector issues low-battery notifications at least 30 days before full discharge and signals this with app alerts, LEDs and audible beeps. A powerful 85 dB siren and distinct alarm tones ensure alarm recognition, while synchronous primary and fallback interconnection modes allow detectors to alert together within seconds, even without hub connectivity. The product uses the Jeweller two-way encrypted radio protocol with automatic frequency hopping for reliable and secure communication.
Suitable for
Residential apartments and houses
Bedrooms, living rooms and hallways
Kitchens and utility rooms (as part of a comprehensive safety plan)
Detached rooms where wireless coverage up to 1,700 m in open space is required
