Abus Funk-Glasbruchmelder  FUGB50000

The acoustic Secvest wireless glass breakage detector detects the specific sound of breaking window panes. The characteristic low- and high-frequency pitches of shattering glass are detected on two levels: a spike in amplitude during the glass breakage followed by a decreased amplitude triggered by the glass shards falling and hitting the surfaces below. The detector only informs the alarm panel when it detects the initial glass breakage followed by the impact of the shards, causing it to trigger an alarm.
