7 ACCESSORIES
The gate can be fitted with several electrical accessories.
7.1 ANTI-CRUSHING SAFETY PROTECTION DEVICES
Vertical switching strips have been fitted to the stationary and/or moving part or parts of the gate.
They are not required for dead man's operation. These strips serve as safety components. The
number of anti-crushing safety protection devices depends on the situation. See appendix A
"
LOCATIONS OF ANTI-CRUSHING SAFETY PROTECTION DEVICES"
Before the gate is moved, the control system checks the status of the anti-crushing safety protection
devices. If one of the anti-crushing strips is faulty, the gate can only be opened and closed in dead
man's operation.
In that case, consult a qualified engineer.
See the chapter “
SERVICE /MAINTENANCE”
7.2 PHOTOCELLS (OPTIONAL)
They detect the gate passage opening. Photocells are located on the stationary part of the gate and
usually take the form of a transmitter and a receiver. If there is an obstacle, e.g. a person between
the transmitter and the receiver, the gate will not close. The photocell does not affect the opening of
the gate.
7.3 LOOP DETECTION (OPTIONAL)
Safety loops in the pavement detect the gate passage opening. If there is an obstacle, e.g. a car on
the loop, the gate will not close. Detection loops do not react to people.
7.4 TRAFFIC LIGHT (OPTIONAL)
Red/green signal lights that indicate the open/closed position statuses. People are only allowed to
pass through the gate opening when the green light is on.
7.5 FLASHING LIGHT (OPTIONAL)
A flashing beacon to ensure extra attention before and while the gate is opening/closing.
7.6 RADIO-FREQUENCY RECEIVER (OPTIONAL)
Remote control to open, stop and close the gate.
