Transform your indoor fire safety with the Ajax FireProtect 2 RB (Heat/Smoke) Wireless Fire Detector in Black (52251.136.BL1)—a groundbreaking Jeweller-enabled guardian that combines advanced smoke and heat detection to outpace modern threats like synthetic-material blazes, ensuring early warnings and swift evacuations. Engineered for high-risk residential and commercial spaces such as kitchens, garages, basements, or living rooms, this sleek black detector employs a double-spectrum optical smoke sensor that identifies particles by size—reacting to true smoke while ignoring water vapor, dust, or insects—backed by a patented smoke chamber that eliminates routine cleaning for hassle-free longevity. Dual external A1R-class thermistors deliver precision: alerting to temperature spikes exceeding +10°C in under a minute or thresholds above +64°C, meeting EN 54-5 and BS 5446-2 standards for Class A1R compliance.

Why the Ajax FireProtect 2 RB (Heat/Smoke) Black is Your Essential Fire Sentinel: In an era of fast-igniting synthetics, this detector excels with interconnected alarm innovation: primary sync activates up to 200 units in just 20 seconds via Ajax hub, while fallback mode coordinates 50+ devices in under a minute during disruptions—using distinct siren patterns and LED indicators (green for normal, yellow for faults, red for alarms) to pinpoint smoke or heat threats for targeted responses. Effortlessly pair via QR code to Ajax hubs for up to 1,700m range (extendable with ReX boosters), unlocking real-time app alerts (iOS, Android, macOS, Windows) with event details like room and timestamp, plus automation: auto-cut power with WallSwitch, trigger emergency lights via Relay, or verify with MotionCam photos. The 85 dB piezoelectric siren blasts at 3m for audible evacuation, with a front-panel button for instant self-tests (hold 1.5 seconds) or temporary muting (5 minutes for alarms, 12 hours for faults)—all while logging 500 events for compliance and review.

Seamless, Secure, and Future-Proof Design: Installation is intuitive: SmartBracket mounting on ceilings or walls (90° adjustable, no tools needed), covering 50–60 m² per unit in IP20 indoor environments (32°F to 122°F, up to 80% humidity). Jeweller's AES-encrypted, frequency-hopping protocol thwarts jamming and spoofing, with tamper detection flagging detachment or sabotage in seconds—plus 36-second loss alerts for unwavering connectivity. Powered by pre-installed CR123A batteries for up to 7 years (optimized mode), it signals low battery 30 days ahead via beeps and notifications, with end-of-life warnings after 10 years for proactive replacement. Certified to EN 50131 Grade 2, CPR (EN 14604), RED, RoHS, EMC, LVD, UL/ULC, FCC, IC, and PSTI UK standards, this Red Dot Design Award winner blends minimalist black aesthetics into any decor while supporting CMS integration (SurGard, SIA, ADEMCO) for professional setups.
