## Long description

The Ajax FireProtect 2 RB Heat Smoke Fire Alarm (black) is a compact residential detector combining smoke, heat, and carbon monoxide detection with a built-in 85 dB siren and wireless communication. Designed for straightforward installation and long autonomous operation, the detector provides timely alerts to users via Ajax apps and supports synchronous interconnection between detectors to ensure fast notification across a home or apartment. The device is available with different battery options and offers a radio range up to 1,700 meters in open space when paired with an Ajax hub.
Advantages
FireProtect 2 delivers stable performance with long battery life and continuous data exchange with an Ajax hub for real-time analysis and false-alarm filtering. The detector issues low battery warnings at least 30 days before full discharge and provides visible and audible indications. A powerful 85 dB siren and distinct alarm tones make alerts hard to miss. Enhanced wireless interconnection ensures that all detectors activate quickly via a primary hub-initiated interconnect or a fallback direct interconnect if the hub is unavailable. The device uses secure two-way Jeweller radio protocol with encryption, authentication, automatic power adjustment, and radio hopping to increase range and resistance to interference.
Suitable for
Residential apartments and houses
Rooms where both smoke and heat detection are required
Homes that use Ajax security hubs or standalone detector setups
