19 Seismic Sensors
Vibration sensors, also called seismic sensors, are used to detect intrusion attempts by mechanical
means, such as drilling or making holes through walls or safes.
Support for seismic sensors is available only if the installation type for the panel is ‘Financial’.
There are several ways to test seismic sensors. The simplest way to test seismic sensors is by hitting a
wall or safe and seeing if the zone opens during a walk test. This means of testing is available with all
types of seismic sensors.
If the seismic sensor is installed with a test transmitter, the following test options are available:
l
Manual testing initiated at the keypad (not supported by the browser);
l
Automatic testing on a periodic basis or when the panel is set using the keypad.
The test transmitter is a small high frequency vibrator that is attached a short distance from the sensor
on the same wall. The test transmitter is wired to an output on the panel or an expander.
Configuring Seismic Sensors in the Panel
1. Configure a seismic zone. Seismic sensors must be assigned to a zone. (See Editing a zone on
page185.)
2. Set the attributes for the zone.
3. Enable automatic testing of the sensor with the Seismic Test attribute.
4. Select a calendar to control the seismic zone, if required.
5. Assign this zone to a verification zone if audio/video verification is required.
6. Configure timers to specify how often to test seismic zones (default is 7 days) and the duration of
the tests. (Automatic Seismic Test zone attribute must be set). (See Timers on page179.)
7. Configure an output for testing a seismic zone. (See Outputs types and output ports on page104.)
The output can be assigned to either the system or an area, if the panel is configured to use areas
as is usually the case in financial environments. The output should only be assigned to the system
if the panel does not use areas.
Using the Keypad
1. Select FULL ENGINEER > ZONES > (select zone) > ZONE TYPE > SEISMIC.
2. Select FULL ENGINEER > ZONES > (select zone) > ATTRIBUTES > SEISMIC AUTOTEST.

19.1 Seismic Sensor Testing
Seismic zones must be configured in order for both manual and automatic tests to be available. The
results of either manual or automatic testing are stored in the system event log.
During a seismic test, one or more seismic zones are tested. When a zone is tested, all other zones in
the same area are temporarily disabled as there is a single seismic test output per area.
