It listens for breaking glass rather than watching for movement, so it raises the alarm at the moment of entry rather than after the intruder is already inside.\u003c\/p\u003e\n\u003cp\u003eA sensitive electret microphone covers glass from 1 to 30 ft away across a 180° angle, with three adjustable sensitivity levels. Jeweller radio reaches up to 3,250 ft in open space and the pre-installed CR123A battery lasts up to 7 years.\u003c\/p\u003e\n\u003cp\u003eThe DualTone digital algorithm is what keeps barking dogs, traffic and slammed doors from triggering it: the detector must hear the dull low-frequency sound of the impact followed by the ringing high-frequency sound of breaking glass within 1.5 seconds before it reports an alarm. Terminals accept a third-party wired detector with a normally closed (NC) contact. The SmartBracket panel lets an installer mount the device on the wall without disassembling the enclosure, and the detector pairs with the hub by scanning a QR code. Correct installation at a height of 2.4 m with the lens perpendicular to the likely intrusion path is what delivers the stated detection pattern and pet immunity. It can be reconfigured remotely from the Ajax apps without a site visit. Supplied in the black finish. The same device in white is stocked as 42805.05.WH3.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWireless glass break detector for windows, glazed doors and
