Ajax EN54 FireProtect (Smoke) — Wireless addressable smoke detector (Black)

Professional EN54‑certified wireless point smoke detector using the Ajax Jeweller two‑way radio protocol. Designed for integration into EN54‑compliant systems, the detector combines a dual‑spectrum optical sensor with the HazeFlow 2 algorithm and a patented dust/insect‑resistant smoke chamber to reduce false alarms.

• EN54‑certified for professional fire alarm systems (addressable events, zone assignment and monitoring station protocols supported).
• Dual‑spectrum optical sensor (Blue + IR) with HazeFlow 2 for improved detection and false‑alarm rejection.
• Jeweller encrypted frequency‑hopping radio — long range (up to 1,700 metres open space) and addressable reporting to Ajax PRO/CIE.
• Battery powered (2× CR123A pre‑installed) with tool‑free replacement; typical battery life up to 6 years under standard settings.
• Tamper detection (SmartBracket removal and smoke‑chamber lid tamper) and detailed event reporting (Contact ID / SIA / ADEMCO 685 etc.).
