Empower your home or business with life-saving vigilance using the Ajax FireProtect 2 RB (CO) Wireless Carbon Monoxide Detector in Black (63213.166.BL1)—a state-of-the-art Jeweller-enabled sensor that detects lethal CO buildup before it becomes deadly, integrating flawlessly into Ajax's ecosystem for unmatched responsiveness and peace of mind. Engineered for indoor environments like kitchens, garages, boiler rooms, or offices, this compact detector uses advanced chemical sensing to trigger alarms at critical thresholds: 70 ppm over 60–240 minutes, 150 ppm in 10–50 minutes, or 400 ppm in 4–15 minutes—stopping only when levels drop below 40 ppm. As part of Ajax's fire detection lineup, it operates 24/7 in Always Active mode, unaffected by system arming, and supports autonomous standalone use with built-in LED and siren alerts for ultimate reliability.
Discover Why the Ajax FireProtect 2 RB (CO) Black is Essential for Modern Safety: Carbon monoxide—the silent killer produced by fuel-burning appliances—claims lives annually, but this detector changes the narrative with rapid response and intelligent features. Its piezoelectric siren blasts up to 85 dB at 10 ft to evacuate occupants, while Interconnected Alarm syncs with other FireProtect devices in seconds, broadcasting the exact threat via unique sound/LED patterns for precise action. Customize via the Ajax app: enable automation scenarios to auto-shutoff ventilation with WallSwitch, activate emergency lights, or notify CMS via SurGard/SIA protocols—reducing response times and enhancing compliance. The tamper-resistant SmartBracket mount sends instant sabotage alerts, and the Test/Mute button silences alarms for 5 minutes or faults for 12 hours, with a simple press activating self-tests that verify functionality in under 30 seconds.
Seamless Integration, Longevity, and User-Centric Design: Pair effortlessly with Ajax hubs (OS Malevich 2.15+) up to 5,577 ft away, extending via ReX for larger spaces, and monitor real-time states like temperature, battery (up to 7 years with optimization), and Jeweller signal strength through iOS/Android/macOS/Windows apps. Battery Life Optimization (enabled by default) stretches CR123A cells without delaying alarms, while end-of-life warnings (after 10 years) prompt timely replacement—keeping sensitivity sharp. Ideal for proactive protection, it transmits detailed events (device ID, room, group) to PRO Desktop for central oversight, and its eco-friendly design avoids false alarms from VOCs or high airflow. Wall or ceiling mount at 4.92 ft for optimal coverage (every room recommended), with Jeweller's encrypted, anti-jamming protocol ensuring secure, forgery-proof communication.
Backed by EN 50131 Grade 2 certification, UL/ULC compatibility (for UL version), and a 2-year warranty, the Ajax FireProtect 2 RB (CO) Black isn't just a detector—it's your invisible shield against CO poisoning, blending cutting-edge tech with intuitive controls for families, facilities, and pros. Install in minutes with QR-code pairing, run monthly tests for confidence, and join millions protected by Ajax's innovative ecosystem—elevate your fire safety today and breathe easier knowing danger is detected, not just hoped against.
