Ajax FireProtect 2 (Heat / Smoke / CO) Jeweller

A next-generation wireless fire detector combining heat, smoke, and carbon monoxide (CO) sensing in one compact device. Designed for smart homes and security systems, it offers early warning from multiple hazards while minimizing false alarms. ajax.systems+2ajax.systems+2

Key Features & Capabilities

• Triple hazard detection — includes a dual-spectrum optical smoke sensor, temperature (heat) sensor, and electrochemical CO sensor to detect fire, smoldering, and dangerous gas situations. ajax.systems+1

• Dustproof smoke chamber — designed to resist contamination from dust and insects, and does not require regular cleaning. ajax.systems

• False alarm suppression — intelligent algorithm (HazeFlow 2) analyzes data from the dual-spectrum sensor to distinguish smoke from vapor or steam. ajax.systems

• Heat alarm behavior — triggers on rapid temperature rise or when threshold temperature is exceeded (for instance, rise of ~50 °F within 1 minute or above ~147 °F) ajax.systems

• CO detection dynamics — the CO sensor is tuned to detect dangerous gas concentration levels early (e.g. 50 ppm in ~90 minutes, 100 ppm in ~40 minutes, 300 ppm in ~3 minutes) ajax.systems+1

• Built-in siren & LED alerts — 85 dB siren for audible warning, plus LED indications for alarm, fault, and status. ajax.systems+2ajax.systems+2

• Wireless connectivity (Jeweller protocol) — secure two-way radio link to the Ajax Hub, supporting encryption, device authentication, and rapid alarm transmission. ajax.systems+2ajax.systems+2

• Interconnected alarm logic:
    • Primary interconnect — via the Hub: when one detector triggers, the hub propagates alarm to all detectors (within ~20 seconds) securityonscreen.com+1
    • Fallback interconnect — if hub is unreachable, detectors notify each other directly (within ~60 seconds) securityonscreen.com+1

• Versions with battery options:
    • RB (Replaceable battery) version — uses CR123A batteries; up to ~7 years of operation. ajax.systems
    • SB (Sealed battery) version — sealed internal batteries; up to ~10 years of lifetime. ajax.systems
    • AC version (mains-powered with battery backup) — alternative for installations where continuous power is available. ajax.systems+1

• Tamper & reliability features — includes tamper detection (removal from mount), supervision for communication loss, and alerting on low battery or end-of-life. ajax.systems+2ajax.systems+2

Technical Specifications

Applications & Use Cases

• Ideal for residential, commercial, or mixed-use installations where comprehensive fire and carbon monoxide protection is desired in one device.

• Excellent in areas where both smoke and CO danger exist (e.g. near gas appliances, heating systems, bedrooms, utility rooms).

• Useful for installations where false alarms must be minimized (kitchens, bathrooms) thanks to advanced filtering.

• Can function independently (standalone) or as part of a full Ajax security+fire system with real-time remote monitoring and logs.
