Detetor de fumo e calor/CO Ajax FireProtect 2 SB — alimentado por bateria, preto, alcance 1700 m, 86×86×43,5 mm

Ajax FireProtect 2 SB is a compact combined smoke, heat and carbon monoxide detector in a black housing, powered by batteries and equipped with a built-in fire horn. The device is designed for early detection of smoke, sudden temperature rise and elevated CO levels in homes and small commercial premises. With a wireless communication range up to 1700 m in open space and dimensions of 86 × 86 × 43.5 mm, the detector provides autonomous operation, continuous status reporting and audible alerts to notify occupants and external monitoring via Ajax apps when connected to the system.

Advantages

FireProtect 2 SB integrates three sensing functions — smoke, heat and carbon monoxide — in one compact unit, enabling rapid and reliable detection of different fire and combustion hazards. The detector features a powerful built-in siren (85 dB) and configurable alert patterns, low-battery advance notifications, and multi-mode wireless interconnection that triggers group alerts both via the hub and directly between detectors if the hub is unavailable. Two-way secure radio communication with encryption and automatic power adjustment ensure stable data exchange and long battery life, while the mounting design and in-app setup streamline installation and maintenance.

Suitable for

• Residential apartments and houses
• Small commercial premises such as offices, studios and retail spaces
• Rooms where combined smoke, heat and CO detection is required (kitchens, living rooms, bedrooms)
• Properties that require wireless integration with a monitoring hub or standalone battery operation

How to use

Install the detector on a ceiling or high on a wall following local fire-safety recommendations, using the SmartBracket mounting plate to fix and level the unit without disassembly. Insert the battery version supplied with the device if required and pair the detector with an Ajax hub using the Ajax app for remote configuration and monitoring; the detector can operate standalone on battery power if a hub is not used. Verify correct placement and perform a manual test via the app or by pressing the detector’s front panel to confirm the sensor, siren and communication functions. The device performs automatic self-tests and reports status to the hub or app.

Recommendations

Place detectors in sleeping areas and on each level of the premises, avoid mounting directly above stoves or in very dusty or humid locations that may cause false triggers, and follow local regulations for spacing and number of required devices. Regularly check battery status through Ajax apps and run manual tests after installation or maintenance to ensure reliable operation.
