Thank you for selecting the GB-30 "glass break" detector, designed for professional security applications. Please follow the instructions in this manual carefully to optimize use of your glass break detector, which has been 100% quality control tested to ensure proper operation and unit
durability. Glass break innovative Model GB-30 incorporates stateof-the-art audio frequency glass break detection and infra-sound impact analysis in its full spectrum. Model GB-30 can simultaneously recognize the low frequency signal generated whenpressure is applied to glass surfaces in
protected areas, as well as the characteristic sound created when glass is broken. The result of this dual analysis is virtually "false alarm free" glass break detection. Combine bi- level an alysis with sensitivity adjustment and you've got GB-30, the most advanced glass break detector
available on today's security market.
RFI / EMI Low Frequency 4.5m - 9m Range Glass Break Alarm Motion Detectors With 2 Colors
Glass break delivers effective coverage in the presence of plate, tempered, and laminated glass, without the need for special
sensitivity adjustments. However, since optimal performance is dependent on secure, vibration-free mounting, there must
be no play between the panes under surveillance and their framework. Glass break can be used in most protected areas, inc
luding rooms with blinds, curtains, or multiple windows, as long as careful coverage tests are conducted using Test trek 1.
Breakage in panes of glass 16" X 24" or larger will be detected, for every standard thickness of plate (1/8"-1/4") and tempered
glass (1/8"-1/4"). Breakage in panes of glass 28" X 28" or larger will be detected for every standard thickness of laminated
glass (1/8"-1/4"). Glass break detector should not be connected to 24 hour protection zones. Installation is not recommended
in protected areas that contain any of the following:
1.windows with closed wooden interior shutters
2.windows with insulated, lined, or sound-muffling drapes;
3. rooms with ceilings higher than 15' (if ceiling mounted);
4. rooms smaller than 10' X 10' where loud noise is common (due to use of kitchen appliances or stereo systems);
5. rooms where machinery noise is present (air compressors, etc.)
