9.1.1 Gross Attack Sensitivity

The Gross Attack setting measures vibration activity for a specified

length of time. There are four settings:

• Low

• Low to Medium

• Medium to high

• High

The settings determine the length of time vibration activity is

measured.

9.1.2 Minor Attack

Programming at the control panel determines how many repetitive

taps (single vibrations) detected by the sensor indicate a minor

attack. The Minor Attack setting is either enabled or disabled. If it

is enabled, there are two settings:

• Four Taps

• Eight Taps

When a tap occurs, a 90-sec timer starts. If the tap count exceeds

the four or eight count threshold within 90 sec, an alarm is

transmitted.

A single tap such as a branch in the wind lightly brushing a

window can start the minor attack timer and tap count. To

avoid false alarms, do not use the Minor Attack setting

where there is potential for stray vibrations.

9.2 Test Mode

The unit is automatically in Test mode for the first 10 minutes after

power up.

The green LED flashes:

• Once to indicate initialization is complete and the unit is in

Test mode

• Twice to indicate a Minor Attack test

• Three times to indicate a Gross Attack test
