In Case Of Power Failure; Mechanical Assembly - Automatic Systems PNG382 Field Manual

2.6. In case of power failure

•
Except type PNG380, the equipment includes an emergency power backup that activates the motor of each
mechanical group as soon as the electrical power supply is off (power failure), thus allowing all the obstacles
of the battery to open automatically. This system is called the "anti-panic opening device".

Note: Each obstacle is actuated by its own associated mechanical group. An intermediate element hence
includes two mechanical groups, and an outer element (left or right) includes one.
