requiring greater security as the gate closes immediately behind the vehicle or person passing through.
PIRAC will operate only if a protection beam or other type of vehicle detection system (e.g. inductive loop) has been fitted.
The remote transmitter or intercom pushbutton will only open the gate. As a vehicle drives through the entrance it activates the protection beam and as soon as the vehicle clears the beam, the gate will close immediately, even before it is fully open.
If the gate reaches the fully open position without the beam being activated the gate will wait the AUTO-
CLOSE time and then re-close. If, however, a vehicle passes through the entrance activating the beam, the gate will close the moment the vehicle has cleared the beam regardless of the AUTO-CLOSE time.
Pedestrian Keyswitch (Optional)
The pedestrian keyswitch is typically fitted to the gate pillar. Its purpose is to open the gate a limited
RELEASE amount for pedestrians. In the case of a double leaf system only the MASTER gate will open.
TURN
Fit key into keyswitch and turn key clockwise as though starting a motor car.
Pedestrian Keyswitch
Let the key spring back to rest position and remove key immediately.
To allow time for removal of the key, there is a 2 second delay before the gate begins to open. If the courtesy light (refer section, “Security / Courtesy light timer”) is connected to the control card, it will flash twice, indicating that the gate will open approximately 1 metre and then stop. After 5 seconds the gate will automatically close.
The gate can be held open by keeping the key turned in the keyswitch. As soon as the key is released back to its normal rest position the gate will close after the 5 second delay.
If a protection beam has been fitted (refer section “Protection Beam”), and the beam is broken while the gate is closing, the gate will stop and re-open to the pedestrian opening point. The gate will remain in that position while the beam is broken and only close 5 seconds, or whatever the pedestrian auto-close time has been set to, after the beam has been cleared.
(The opening distance and the time that the gate remains open can be adjusted to suit. Default values are described above)
Anti-crushing Device
The R3 and the R5 operator incorporates an electronic anti-crushing mechanism that will sense if a person or vehicle has obstructed the gate.
If the anti-crushing mechanism of a single or double gate system is activated while the gate(s) are opening, the operator of the obstructed gate will stop. The second gate in a double swing system will continue to open. The stopped gate can be immediately operated using the remote control or gate release pushbutton provided that the obstruction has been removed. The gate will close. (refer point regarding multiple collision below)
In the case where the gate(s) are closing, both gates will re-open if the anti-crushing mechanism is activated, regardless of which gate is obstructed. As per the above, when activating the system again, both gates will close.
