How to choose and place a glass break detector
Acoustic detectors cover several windows at once, which makes them practical for rooms with large glazed walls where fitting a contact on every pane is not possible.
- Wired or wireless: the ARD511 connects to a zone on a wired panel, while the ARD512-W2 pairs with a Dahua wireless hub.
- Range and line of sight: check the rated detection distance on the datasheet and mount the unit facing the glass, with no curtains or partitions in between.
- Glass type: laminated and filmed glass breaks differently from plain sheet glass, so confirm the detector covers the glass you have.
- Noise sources: keep detectors away from speakers, bells and machinery that could cause false alarms.
Glass-break sensing protects the perimeter. Combine it with motion detectors inside and door contacts on every entry point for layered coverage.
