8.4 Industrial Gate
Warning light
Safety pressure bar
There is often a gate at the entrance to private properties.
This is opened only to let vehicles in and out.
The gate is controlled by the gateman.
8.4.1 Demands on the Gate Control System
•
The gate is opened and closed by operating a switch in
the gatehouse. The gateman is able to monitor the
operation of the gate at the same time.
•
The gate is normally fully opened or closed. However,
movement of the gate can be halted at any time.
•
A flashing light is activated 5 seconds before the gate
begins to move and continues for as long as the gate is
in motion.
•
A safety pressure bar ensures that nobody gets injured
and nothing gets trapped or damaged when the gate
closes.
