Perimeter Flash

Pressing the lock button twice in two seconds arms the DWA in the Perimeter mode (only the doors, hood, and tailgate contacts monitored). After Perimeter arming the LED will flash rapidly, 10ms on with 125ms between flashes for 1 second, then a 1 second pause, followed by the rapid flashing. At the end of this 10 second sequence the LED will flash in the Confidence Mode.
