Glass Break Sensor Planner
An acoustic glass-break sensor listens for the sound of breaking glass across a room, so one unit can watch several panes instead of a contact on every window. Enter how many rooms have glazing, their typical size and the sensor’s listening radius to get how many sensors you need — per room and in total. Planning figures; runs in your browser.
- Rooms with glazing4
- Sensors per room (ceil 18 ÷ 177 m²)1
- Total sensors (4 × 1)4
Planning estimate only — verify against the product datasheet and a site test. Mount the sensor with a clear line-of-sight to the glass (not blocked by curtains or furniture); soft furnishings and double-glazing shorten the range. Combine glass-break with door and window contacts for confirmed alarms, and check each unit with a clap-tester on install. Glass-break suits rooms with lots of glazing where a contact on every pane is impractical.
