10.3 ‐ Safe guard (Infrared device or Photocell)
It is recommended that the installer install the included infrared photocell for
additional safety. Photocells work by inhibiting the movement of the gate if the
beam is broken. Infrared safety devices may be required by law in some areas.
If the infrared beam is broken during closing, the gates will reverse and open
immediately. During opening, the beeper will ring.
Infrared photocells come in active and passive varieties. Active photocells require
power on both sides of the driveway, whereas passive photocells employ a reflector
plate so that power is only required on one side of the driveway. Most photocells
will provide DC power input wires + and ‐, and 2 normally closed switch wires. To
install the photocell, remove the short circuit wire between Terminals (14) and (15).
Attach the normally closed wire to (14) and the other common normally closed wire
to (15) (COM). Attach the +12VDC power for the photocell to (13) and the –DC
power to (15).
The signal wires are not polarized so they can be interchanged without issue, but the
power wires must be wired correctly to prevent damage. Consult your device
manufacturer's documentation for details.
In the closing phase, if an obstacle breaks the infrared beam of the photocell, then the
gate will stop and reverse after approx 3 seconds. In the opening phase, the function
of the photo sensor can be selected between active or passive. If the photo sensor is
set for the active mode, and the infrared beam is broken, then the system will stop
and wait for a new command.
The infrared device is included in your kit, additional devices can be obtained
through your dealer. To find a dealer, go to www.gatekeeperltd.com/dealers
