PROTECTING STOREFRONT GLASS
Merchants often want glass break protection on their front windows, in order to
have the alarm sound as soon as the glass breaks. While this does not prevent
“smash and grab” losses, it will prevent most burglars from actually entering
the building.
For storefront windows shock sensors are always the best choice. A shock sensor is
visible from the outside, which might deter burglars before the glass is broken.
And shock sensors are less likely to be set off by street noise, or by rolling metal
shutters, than are acoustic sensors. Due to range limitations, however, shock
sensors can be more expensive to install. Multiple sensors may be required to
cover the same glass area that one acoustic sensor can protect.
Acoustic sensors can be successfully used to protect storefront glass if store
personnel are properly trained to not block the glass. Acoustic sensors must be able
to “see” all the glass that they are protecting. If a sensor’s line of sight to the glass
is blocked by store displays or furniture, the sensor is unlikely to detect a break-in
through the blocked glass.
If selecting an acoustic sensor, in stores which do not have window displays, mount
a ShatterPro in the ceiling inside the room. For stores with window displays,
mount a ShatterSwitch directly above the glass.
Use the 5115/20 for on-the-glass shock sensor protection, or use the 5425 for
frame mounting.
For acoustic sensor protection, use a ShatterPro II 5810A, a Recessed ShatterPro
5820A, or a ShatterSwitch 5725T.
