GLASS BREAK-ROUND-FRM C-TAMPER

The 5812-RND detects in a full 360 coverage pattern, with a
maximum 25 (7.5m) radius from sensor to glass. Using the
patented Pattern Recognition Technology™, the sensor listens for
actual patterns of breaking glass while eliminating most false
alarm patterns. The 5812-RND listens across the glassbreak
frequency spectrum for greater false alarm immunity.
In independent lab tests, the 5812-RND technology provides 25%
better false alarm immunity than industry leading glassbreak sensors.
The 5812-RND can be tested without opening the sensor by
activating a hand held glassbreak tester at close range. A simple
hand clap feature lets end users confirm at any time that the
5812-RND is powered up.
