Glass Break Detectors — Specs, Brands & Hong Kong Installation

Acoustic detectors that listen for breaking glass across a room — useful for shopfronts and glazed offices.

Glass break detectors for Hong Kong shopfronts and glazed interiors

What this sensor does

Glass-break detectors cover several windows from one device by analysing the flex and shatter frequencies of breaking glass. They suit rooms where putting a contact on every pane is impractical — meeting rooms, living rooms with full-height windows, and street-level retail glass.

Honeywell 5853 is the wireless 5800 option for finished interiors. Bosch DS1101i is the wired acoustic detector we use on G-series commercial jobs.

  • 7.5 m class detection radius
  • Dual-frequency flex / shatter analysis
  • Walk-test LED for commissioning
  • Wired and wireless options

Hong Kong / local context

Street-level glass with heavy traffic can confuse cheap vibration sensors. Acoustic glass-break is usually cleaner on Nathan Road / Causeway Bay shopfronts.

The detector needs line of sight to the glass — do not hide it behind signage or dense displays.

Installation notes

  • Mount on wall or ceiling with a clear path to protected glass; run manufacturer walk-test.
  • Combine with a door contact on the shop shutter so opening and breaking are separate zones.

We survey, supply, mount, walk-test, and name every zone so the keypad makes sense in English or Chinese.
