GLASSPROTECT

The AJAX GlassProtect is a compact wireless indoor detector that recognizes glass breaking up to 9m away using a sensitive electret microphone and DualTone algorithm, which verifies both impact (low-frequency) and shattering (high-frequency) sounds within 1.5 seconds to prevent false alarms from dogs, traffic, or thunder.
It supports three adjustable sensitivity levels via the Ajax app, includes a NC terminal for third-party wired detectors, and uses Jeweller encrypted communication up to 1000m with up to 7-year battery life.
