while the gate is open the "Auto-close" will restart its countdown. If the gate is
activated while the gate is closing the gate will reopen. The gate cannot be stopped
in a midway position and will therefore always close.
A protection beam should be used in conjunction with this facility to prevent the
"Auto-close" from closing the gate onto a vehicle passing through.
PASSIVE INFRA RED AUTO-CLOSE (PIRAC)
This facility is an extension of the Condominium facility described above. It is
designed for applications 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 control 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 close immediately.
Manual Release
All operators are fitted with a manual release mechanism. This is to allow the gate to
be operated in the event of a total malfunction of the equipment It is also required if
the mains power has failed in the case of the A5 and FAAC operators.
