Opening the Unit PowerG 2-way Glass-break PGx922 is a supervised, wireless 2-way glass-break detec- that detects the breaking of framed glass mounted in an out- wall. The PGx922 is protected by a front and back tamper that transmits a tamper message when the cover is or when the base is forcibly detached from the wall. detector is wall/ceiling mountable and suitable for most of window/door glass: plated tempered, laminated, wired, and sealed insulating glass. No adjustment is necessary installation – the detector is fully pre-calibrated. 1. General View Microphone LED To be installed by service persons in non-hazardous only.

After completing the system default, download the programming. Sensor acoustic sensor module of the PGx922 is omni-directional, full coverage. Coverage is measured from the sensor the point on the glass farthest from the sensor. The sensor can mounted as close as 1.5m (5 ft) from the glass. Figure 2. Typical Range Measurement mounted on opposite wall, on adjoining walls or on the the range is 7.6 m (25 ft) for plate, tempered, laminated, coated, and sealed insulating glass.The coverage range depends on the angle between the detector and the glass – a higher angle, maximum range is reduced.

Do not use where white noise, such as air compressor is present. Avoid rooms smaller than 3 x 3 m (10 x 10 ft) and rooms multiple noise sources such as small kitchens, noisy garages, small bathrooms, etc. to avoid: Glass airlocks and glass vestibule areas Noisy kitchens Residential car garages Small utility rooms Stairwells Small bathrooms For glass break protection in such applications, use shock on the windows or window frames. not install in humid rooms Wireless PGx922 is not hermetically sealed. Excess mois- on the circuit board can cause a short and a false alarm. 24-Hour Loop Applications PGx922 is recommended for perimeter loops and is to function in an occupied area. In 24-hour loop appli- where the sensor is armed all day and all night, the alarm prevention technology will be pushed to its limit. sounds can duplicate the glass break pattern the acoustic detects. Install the PGx922 on a perimeter loop which is whenever the door and window contacts are armed. Occupied Areas false alarm immunity is best in rooms with only moderate For 24-hour occupied area protection, use shock sensors. Testing PGx922 is designed to detect the breaking of framed glass in an outside wall. Testing the sensor with unframed broken bottles, etc., may not trip the sensor. The sensor does not trip to glass breaking in the middle of the The PGx922 may not consistently detect cracks in glass, bullets which break through the glass. Glass-break sensors always be backed up by interior protection. Travel Considerations the sound of breaking glass travels directionally out from broken window, the best location for mounting the sensor is the opposite wall – assuming the glass to be protected is the sensors range and line of sight. The ceiling and (side) walls are also good sensor locations. When on the opposite wall,
