• EN54-certified, wireless addressable point smoke detector for integration with EN54 systems and compatible Ajax CIE/hubs.
• Dual‑spectrum optical smoke sensor (blue + infrared LEDs) with protected chamber and HazeFlow 2 algorithm to reduce false alarms from steam and contamination.
• Jeweller two‑way encrypted radio protocol for secure reporting and device addressability; open-space range up to ~1,700 m (actual range depends on region and environment).
• Battery powered (2 × CR123A pre‑installed). Battery life up to 5–6 years depending on polling settings.
• Tamper detection, device QR/ID for pairing, LED status indication, and SmartBracket mounting (option to lock base).

Who it’s for: installers and system integrators specifying EN54‑compliant wireless detectors for commercial and residential fire detection systems across regions that accept EN54 certification.

Important notes & compliance:

• EN54 is a European fire standard (EN54‑7 / EN54‑25 applicable to this detector family). Verify local regulatory acceptance before specifying for installations outside EN54 jurisdictions.
• Ajax EN54 devices are region/frequency specific (e.g. EU 868 MHz vs US 915 MHz). Confirm the SKU frequency and hub compatibility before sale—EU‑frequency units will not operate with US hubs unless the device variant matches the region.
• This listing refers to the smoke‑only variant (119921.275.WH1). Sounder and VAD variants differ in certification and performance (e.g., EN54‑3 for sounders) — confirm variant before publishing technical or pricing information.

Installation & safety: Follow the product manual and local fire code when siting and installing detectors. For monitored systems ensure correct addressing and CIE configuration. For full specifications and installation instructions see the manufacturer manual/datasheet.
