Activity Alarm

The activity alarm is used as a warning when:

  • Ignition turns ON while the alarm is armed, or
  • The unit detects movement while ignition is OFF and the alarm is armed.

The alarm is armed when input 1 (IP1) transitions to high.

When armed:

  • If ignition turns ON, alarm triggers immediately.
  • If ignition is OFF, alarm triggers after 30 seconds of continuous movement.

Once triggered, the device:

  • Reports once with event 06.
  • Then reports with event 07 every minute and at every 45° turn for 5 minutes.

Signals and assumptions

SignalDescription
IP1Alarm arm/disarm input (high = armed)
F12Accelerometer movement detected
F00Ignition ON
C1230-second movement counter complete
C131-minute periodic counter
C145-minute tracking window counter
U08Alarm triggered flag
U09Frequent tracking mode active
J0045° turn signal (must be defined previously)

Activity alarm script commands

1. Start 30-second counter on movement while armed

Silent event: when movement (F12+) is detected and alarm is armed (IP1), start counter C12 for 30 seconds.

>SED44SV0;IP1F12&+;XCT=SGC12TC00030<

2. Trigger alarm condition

If ignition turns ON (F00) while armed (IP1), or if counter C12 completes, set user signal U08 high.

>SED45SV0;IP1F00&C12|+;XCT=SSSU081<

3. Reset when movement stops (while armed)

If movement condition ends, clear the trigger flag and undefine counter C12.

>SED48SV0;IP1F12&-;XCT=SGC12U;XCT=SSSU080<

4. Alarm trigger report (event 06)

When U08+ occurs, send event 06, enable frequent tracking (U09), start 1-minute (C13) and 5-minute (C14) counters, and clear U08.

>SED06NV4;U08+;XCT=SSSU091;XCT=SGC12U;XCT=SGC13TR00060;XCT=SGC14TC00305;XCT=SSSU080<

5. Frequent tracking reports (event 07)

While alarm tracking is active, report event 07 on each 45° turn (J00) and every minute (C13).

>SED07NV4;J00U09&C13|U08|+<

6. Stop frequent tracking

If 5-minute counter C14 completes or the alarm is disarmed (IP1!), clear counters and tracking flags.
