follow the steps below to prevent unintended triggering of the system. The switch (2)
has three positions.
Upper position: = Battery/Circuit test
Central position: = (OFF) The system is switched off
Lower position: = (ARMED if ON) The system is armed if the red LED will be ON. If
either the wiring or firing detonator is faulty or the detonator is
either not there or has already fired, then the LED will not light.
Testing the trigger switch:
Set the switch on the control unit to the upper position
The green LED lights up 1 sec. (battery is OK)
The system is in test mode and not active. The trigger switch on the center console
and the outside trigger switch can now be actuated.
