PROTECTING GLASS DOORS AND
WINDOWS THAT OPEN
Protecting glass doors and windows that open can be a challenge because of the
difficulty of running wires from the glass to the frame. Glassbreak and forced-open
protection can, however, be achieved with a single detector.
For shock sensor protection, both on-the-glass and frame-mounted sensors can be
used. The 5120C shock sensor ships with 3 ft. (.91 m) of coil cord. The sensor
mounts in a corner on the glass, and the coil cord reaches to a termination on the
frame. As the window or door opens, the coil cord stretches as needed.
Frame-mounted shock sensor models are available which also have a built-in reed
switch with magnet. These sensors provide both glass break detection as well as
forced open detection. Mount the sensor’s magnet on the door or moveable
window, and mount the sensor on the frame as close as possible to the magnet.
For acoustic sensor protection use a Sentrol ShatterSwitch with built-in reed
switch and magnet. This provides coverage of 10 ft. (3.05 m) of glass, including
multiple windows, while detecting forced opening as well. The ShatterSwitch
should be centered at the top of the glass, or as near to center as practical for
magnet location.
Use a 5120C shock sensor with coil cord for on-the-glass protection. The 5426
frame-mount shock sensor with built-in reed switch provides double protection.
The ShatterSwitch is available in standard configuration, part number 5725T, and
also with built-in reed switch, part number 5728T. A 90˚ mounting bracket, part
number 5702, is useful on narrow frames.
