4. TECHNICAL SECTION

4.1. Introduction

Before operating a series 380 PNG, it is necessary to programme the PLC. Resetting the PLC immediately
activates this programming which determines the configuration of the PNG:
- type of PNG (380, 381A, 381B or 382),
type of pictogram management (extended or limited) by passage direction,
-
- extension of the security zone in addition to CS : C6, C7, C13 or C14,
- operation mode of the readers (with or without passage authorization storage),
- activation level of the "evacuation" mode (0 or 1),
possible locking of reader in pre-alarm or "intrusion".

4.2. Principles of operation

4.2.1.

Types of fraud

Three types of fraud are treated. When a fraud is detected, the obstacle closes immediately. The buzzer
is activated more or less rapidly according to the type of fraud.

4.2.1.1. "Intrusion" Fraud (fig. 13a):

When the PNG is on stand-by, intrusion is detected as soon as there is a presence before at least one
cell in an entrance corridor.
If the person is not authorized to pass, the PNG will sound an alarm after a time-out (% TM2) (15 sec by
default): the buzzer is activated and the pictograms show a red cross.
The PNG will immediately sound an alarm if a presence is detected at the door-zone (photocell C6 or C7)
during the time-out.
The alarm will end when there is no longer any presence in any of the two entrance corridors (A and B)
and after a short time-out (%TM0) (1 sec by default)
