Centurion D2 Turbo Installation Manual page 55

We highly recommend that a pair of Safety Beams are installed across the gate
entrance and connected to the Closing Safety Beam input on the
D2 Turbo if you select Open Only Mode. This will prevent the gate from closing
on people, pets or vehicles (page 50).
PIRAC (Beam Autoclose) (page 56) can be used with Open Only Mode.
20.1.2.3. Reversing Mode
Reversing Mode offers slightly more security than Standard Mode as it allows you to close
your gate quickly by pressing, for instance, your remote control just as you drive through
the gate to prevent children or pets running out - or anybody getting in behind you.
When pressing the button of the remote control or the gate pushbutton on the intercom,
your gate will be set in motion. If you press the button again, the gate will move in the
opposite direction. So, if the gate is opening and you press the button, the gate will stop
and immediately start to close (and vice versa).
Autoclose (page 51) and PIRAC (Beam Autoclose) (page56) can be used with
Reversing Mode.
To configure any of the operating modes please refer to the section, 'Customising the
Features and Functions' on page 60.
21.1.3. Automatic closing (Autoclose Mode)
The D2 Turbo/D2 Turbo Low-Voltage has the facility to automatically close the gate
after it has opened (Autoclose Mode). The time that the gate stays open is by default
fifteen seconds, but this time period can be set to be five, ten, fifteen, thirty, or forty-five
seconds.
As described in the previous section, Autoclose Mode is selectable with Standard Mode
(page 50) and Reversing Mode (page 51) - by default the function is Off.
However, Autoclose is automatically enabled in Open Only Mode.
We highly recommended that a Safety Beam is installed across the gate
entrance and connected to the Closing Safety Beam input on the D2 Turbo, if
you select Autoclose in order to prevent the gate from closing on people, pets
or vehicles.
