Ajax EN54 FireProtect (Smoke/Sounder) — Jeweller is a wireless, addressable point smoke detector with an integrated audible sounder for indoor fire detection and local annunciation. Designed for professional and commercial installations as well as advanced residential systems, the unit communicates with Ajax control panels using the Jeweller two‑way radio protocol.

• EN54‑certified smoke detector with integrated sounder for compliant fire alarm systems.
• Dual‑spectrum optical sensor (blue + infrared) in a dust and insect‑protected chamber to reduce false alarms (e.g. steam).
• Built‑in sounder (up to ~85 dB @ 1 m) with multiple selectable tones and system synchronisation for coherent alarm signalling.
• Wireless Jeweller communication with fast alarm transmission to the control unit (reported under 3 s) and long open‑space range.
• Two tamper protections (SMARTBracket removal and smoke‑chamber lid removal) and long battery life from 2 × CR123A pre‑installed cells.

Use cases: Suitable for commercial and residential fire detection projects requiring EN54 compliance, or for security installers deploying Ajax EN54 systems where wireless, battery‑powered point detectors with local sounders are required.

Safety and compliance notes: Check the supplied datasheet and EN54 certification documents for project tender requirements. Verify regional radio variant (EU vs US frequencies) for compatibility with local Ajax control units. Installation must follow manufacturer instructions and local fire regulations; professional installation is recommended for EN54 systems.
