  ASC-SS1
Glassbreak Sensor
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.
