Reversing Mode

Apart from the Standard Mode of Operation as described in the section Normal
Operation, the system offers another Mode of Operation. Referred to as Reversing
Mode, if the transmitter is pressed while the gate is moving, the gate will automati-
cally reverse direction. The gate can never be left in mid position with this mode
selected.
Other Modes of Operation which can be selected and operated using a radio
transmitter are CONDOMINIUM and PIRAC, which are described below.

Condominium

The system can be programmed for "Condominium" operation. This Mode of
Operation will override the normal Mode of Operation described under the section
"Normal Operation". This facility is designed for greater safety and security in
applications where there will be a number of users, such as the gate at a townhouse
estate, factory or office park the "Autoclose" facility described earlier.
In "Condominium" mode "Autoclose" cannot be overridden. If the remote control or
intercom pushbutton is pressed while the gate is open the "Autoclose" 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
"Autoclose" from closing the gate onto a vehicle passing through.

Passive Infrared Autoclose (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.
In this mode and for a particular application should the gate start to close too quickly
