Flap Barriers, PG 1

The retractable flap Barrier controls pedestrian access between public and secure areas. The barrier lane uses an array of optical sensors to determine the number and direction of persons passing through the lane. The barrier uses a retractable flap to block the pedestrian's path. The barrier is able to authorize passage to persons presenting a valid electronic security card (or other authentication device). The barrier can integrate with the building access control system.

Controller
An industrial computer (PLC) is used. This allows flexibility for software upgrades or adjustable timers.

Operation modes
The barrier provides bi-directional access control. Each direction may be in one of three states:-
. Free passage: all person are authorized to pass under all conditions
. Controlled access: each person must use a card reader before being authorized to pass Lane closed: no persons are authorized to pass, and security cards are ignored

Configuration
It is possible to control the barrier (set free passage/ card access/ lane closed mode, clear alarms, manually authorize
access for a single person) by all of the following methods:-
• From the access control system
• From a desktop-mounted control panel
