PROTECTING LARGE ROOMS WITH
MULTIPLE WINDOWS
Most large rooms have several windows, often widely spaced from each other.
The most economical way to protect large rooms with multiple windows is with a
single, long range acoustic sensor. However, care should still be taken to match
sensor range to room size. A sensor whose range extends well beyond the
boundaries of the room is acoustically “hot” and vulnerable to false alarms.
For protecting glass on more than one wall, ceiling mounting is most desirable.
Make sure that all protected glass is within the radius coverage of the sensor. For
any glass to be protected by an acoustic sensor, the distance from the bottom of
the window to the sensor must be no more than the sensor’s maximum range.
For protecting one wall of glass, mounting an acoustic sensor on the opposite wall
is best (if all the glass to be protected is within the sensor’s range).
Always confirm range with a Sentrol 5709C hand-held tester.
For glass areas less than 10 ft. (3.05 m) or behind heavy curtains use a Sentrol
5725T ShatterSwitch mounted on the frame. For protecting large glass areas, a
single 5810A ShatterPro II, with its 25 ft. (7.6 m) range, can protect up to four walls
of glass. The 5820A Recessed ShatterPro II mounts in a 1 in. (2.54 cm) hole in the
ceiling, opposite wall or adjacent walls.
