GB-02-2014 | Acoustic Glassbreak Sensor

Scope and Benefits

SIA developed these recommendations as an advisory to Underwriters Laboratories for enhancing UL 639 Intrusion Detection Units, adding false alarm tests for acoustic glassbreak detectors and room specifications for glassbreak detection tests.

To the security industry at large, SIA recommends the tests in this report as a measure of an acoustic glassbreak detector’s ability to reject false alarm sounds and maintain its detection capability.

These test are not exhaustive but are thought to represent several classes of common false alarm sounds.

They were selected by a ranking process of known false alarm sound sources. They represent the most common false alarm sounds that can be accurately and consistently reproduced for testing detectors.
