Ajax EN54 FireProtect (Heat) — Jeweller is a wireless addressable point heat detector for indoor use as part of the Ajax EN54 fire line. It detects rapid temperature rise and fixed‑temperature thresholds using two built‑in thermistors and reports events over Ajax's secure Jeweller radio protocol to compatible Ajax EN54 hubs/CIEs. The detector ships with pre‑installed CR123A batteries and includes tamper protection and LED status indication.

  • EN54‑5 & EN54‑25 compliant — suitable for EN54 line integration (verify local certification requirements).
  • Dual thermistor detection — rate‑of‑rise and fixed temperature modes; multiple heat response classes configurable (A1/B/C and R/S variants).
  • Jeweller wireless protocol — addressable communication with Ajax EN54 hubs and range extenders (regional radio band dependent).
  • Pre‑installed batteries — 2 × CR123A supplied; tool‑free replacement. Typical battery life up to 5–6 years with default polling.
  • Tamper & LED status — anti‑tamper SmartBracket and multi‑colour LED indicators for alarm/state.

Installation & compliance: Designed for indoor installation where smoke detection is unsuitable (e.g. kitchens, garages). Installers must follow local fire codes and the official Ajax EN54 installation manual. Verify radio band compatibility (region) and confirm model SKU before installation.
