Glassbreak Shock Sensor
- Mounts directly on glass surface
- Protects all glass types: plate, tempered, laminated and wired
- Outstanding false alarm immunity
- Epoxy sealed against moisture and corrosion
The ASC-SS1 shock sensor protects all types of glass: plate,
wired, tempered, and laminated. The sensor will protect the glass within an 8
feet radius from the sensor for glass up to 1/4 inch thick. The ASC-SS1 mounts
directly to the glass surface and is wired to a two wire powered protective
loop.
Wiring
The ASC-SS1 shock sensor is a two wire electronic device which
draws minimal current (< 1mA) from the protective loop. When glass is broken,
the sensor provides a normally-closed solid-state output (circuit opens on
alarm) which is not polarity sensitive. The sensor employs transient suppression
devices to protect against lightning.
The ASC-SS1 shock sensor does not require a processor.
The ASC-SS1 shock sensor may be wired in series with multiple
sensors. Care should be taken to ensure that the total resistance of the sensors
in series does not exceed the capabilities of the alarm control panel.
Testing
To test the shock sensor, hit the protected glass on the corner
furthest from the sensor (see diagram) using a blunt plastic or hard rubber
object. This impact should create enough energy for the sensor to generate an
alarm condition. Actually breaking the glass would create more energy than the
test, so if the test impact causes the sensor to generate an alarm, protection
is assured.
If the unit is tested in the alarm circuit, tripping the detector
should trip the alarm panel. An alternate test method is to connect the sensor
to an ohm meter and watch the resistance (less than 20(omega) when not in alarm)
increase to greater than 1M(omega) for at least 1 second during an alarm
condition.
Installation
The ASC-SS1 shock sensor must be mounted in a corner of the
glass. For best performance, do not mount the sensor closer than 1" from the
window frame.
Shock sensors mount with double coated acrylic foam tape designed
to resist the types of environmental stresses the shock sensor will experience
after installation. |
