Wireless indoor glass‑break detector — GlassProtect U (Jeweller)

The GlassProtect U is a compact, battery‑powered acoustic glass‑break detector designed for indoor wall mounting. It uses an electret microphone and a DualTone two‑stage detection algorithm (impact + fragment ringing) to reduce false alarms and reliably detect glass break events, reporting to an Ajax hub via the Jeweller encrypted two‑way protocol.

• Key features:
• DualTone acoustic detection (impact + ringing) for fewer false alarms.
• Detection coverage up to 9 m and ~180° horizontal angle; three sensitivity levels (Low/Normal/High).
• Pre‑installed CR123A battery with multi‑year life (Ajax rates up to ~7 years depending on polling interval).
• Jeweller wireless protocol (encrypted two‑way comms) with up to 1,000 m open‑space range to the hub/repeater.
• SmartBracket mounting and anti‑tamper protection; terminal for one wired NC contact.

Use cases

• Domestic and commercial indoor protection for windows and glazed areas.
• Ideal where acoustic detection complements accelerometer/impact sensors or where line‑of‑sight coverage is limited.

Installation & safety

• Mount on an interior wall aimed at the protected glazing, following the datasheet mounting heights and orientation for reliable coverage.
• Test sensitivity and placement to avoid nuisance alarms from routine impacts or strong vibration sources.
• Use only the specified CR123A battery type; replace with the same specification and observe polarity.

Compliance & notes

• Intended for indoor use only (IP50). Check regional certification (CE / UKCA) and confirm the exact SKU (130351.05.WH1) for compliance and variant details.
• Refer to the official datasheet and user manual for full installation and commissioning guidance.
