Power Sounder, Disarm:  

There are four different ways to disarm the Power Sounder:

The Power Sounder remains deactivated until the ground cable is reconnected to the vehicle battery.  

2  If alarm is triggered by a signal from the ATWS control unit or by disconnection of the ground cable from the vehicle battery, the power sounder is automatically reset after the alarm period of 30 seconds has elapsed. However, the power sounder is still ready for alarm.  

3  The audible alarm is cancelled if the alarm is triggered by a signal from the ATWS control unit and the signal is then cancelled before the alarm period (approx. 30 seconds) has elapsed.
