Ajax EN54 FireProtect (Sounder) — Red
EN54‑certified wireless addressable fire alarm sounder designed to operate as part of an Ajax EN54 fire system (requires compatible Ajax EN54 Fire Hub/CIE). Provides a high‑volume local audible alarm with selectable tones and levels, two‑way Jeweller radio communication for addressability and supervision, and battery operation with tool‑free replacement.

• EN54 certified audio annunciation for compliant installations (EN54 family / EN54‑3 applicable).
• Jeweller two‑way radio protocol — long open‑space range (advertised up to ~1,700 m).
• High sound output — up to ~100 dB at 1 m (model/setting dependent); dozens of selectable tones and alarm synchronisation.
• Battery powered (pre‑installed CR123A cells), tool‑free replacement and long service life (typ. up to ~5 years depending on settings).
• Quick SmartBracket mount for fast professional installation (wall or ceiling); tamper detection and optional locking.

Use cases: professional fire alarm installations in commercial and residential buildings requiring EN54 compliance, retrofit systems where wireless addressability reduces cabling, and monitored sites where supervised two‑way radio reporting is needed.
