Sample Configuration - Automatic Systems PNG382 Field Manual

2.8. Sample configuration

•
The sample configuration below shows a four passage-way bidirectional PNG382/NC battery (reversible).
The structure comprises two outer elements (1 and 5), and three intermediate elements (2, 3, and 4).
Element 1 is of the left type, and element 5 of the right type.
•
"PNG" stands for "Unattended Passage" in French. This security gate has indeed been developed to control
pedestrians' flow at unmanned access points. A remote control desk is, however, available as an option.
•
"NC" (Normally Closed) means that when switched on, ready to operate, the obstacles are always closed
and open only when the passage is authorised. The system can alternatively be configured to operate
Normally Open ("NO"), i.e., the obstacles are always open and close only in case of fraud attempt.
Situation 1: Bidirectional access controlled by PNG forming four lanes in a Normally Closed configuration.
All obstacles are locked in the closed position, passage is not allowed.
Situation 2: The obstacles all retract during a power failure and free passage is possible in both directions,
thanks to the integrated anti-panic opening device. All obstacles are in the open position.
