Ignite proactive fire safety in your living spaces with the Ajax FireProtect 2 RB (Heat/CO) Wireless Fire Detector in Black (63211.167.BL1)—a next-generation guardian that detects smokeless blazes and invisible carbon monoxide dangers before they escalate, blending advanced sensing with seamless Ajax ecosystem integration for unmatched residential protection. Tailored for high-risk zones like kitchens, garages, barns, basements, or boiler rooms, this compact black detector employs two external A1R-class thermistors to spot rapid +10°C rises in under a minute or temperatures exceeding +64°C, while its built-in chemical sensor alerts to CO buildup at thresholds as low as 50 ppm over 90 minutes—ensuring early warnings without false alarms from vapors or drafts. Whether operating standalone with piercing 85 dB siren blasts and LED strobes or synced to your Ajax hub for app-driven evacuations, it delivers peace of mind through intelligent, tamper-proof design that notifies of sabotage, low battery, or end-of-life in real-time.
Discover Why the Ajax FireProtect 2 RB (Heat/CO) Black Excels in Modern Fire Defense: In an era of synthetic materials fueling fast-spreading, smoke-free fires, this detector rises above with interconnected alarm technology: primary sync activates up to 200 units in just 20 seconds via Ajax hub, while fallback mode rallies 50+ devices in under a minute—distinguishing heat from CO threats with unique sound patterns and color-coded LEDs for swift, targeted responses. Customize via intuitive Ajax apps (iOS, Android, macOS, Windows) to automate scenarios: trigger WallSwitch to cut power, Relay to illuminate escape routes, or MotionCam PhOD for photo-verified alerts—transforming passive detection into active lifesaving. Its Jeweller protocol ensures encrypted, anti-jamming communication up to 1,700 m in open spaces, extendable with up to 5 ReX boosters for multi-story homes or concrete-heavy builds, all while sipping power for up to 7 years on replaceable CR123A batteries (or 10 years sealed in SB variant).
Effortless to install and maintain, the FireProtect 2 mounts via adjustable SmartBracket in seconds—no disassembly or tools needed—positioned at ceiling height for optimal coverage of 50–60 m² per unit. Tamper detection flags detachment or damage instantly, self-tests sensors with a single app command or front-panel press (activating the 85 dB test siren), and logs 500 events for forensic review. Compliant with EN 50131 Grade 2 standards, it's eco-friendly, maintenance-free, and future-proof with over-the-air updates—ideal for homeowners, Airbnb hosts, or small businesses seeking scalable fire solutions without monthly fees.
Elevate your safety quotient with the Ajax FireProtect 2 RB (Heat/CO) Black—where cutting-edge thermistors, decade-long CO vigilance, and Ajax's trusted wireless prowess converge to outsmart fire's silent threats. Deploy in every room for synchronized serenity, and rest assured: in emergencies, it doesn't just detect—it deploys your defense. Discover why Ajax fire detectors lead in reliability, earning global acclaim like the PSI 2025 award for saving lives through innovation and simplicity.
