Connecting Additional Safety Devices
The GTO/PRO® 3000/3200 is equipped with built-in obstruction sensitivity. The operator is designed to stop and reverse
the gate within 2 seconds when it comes in contact with an obstruction. However, obstruction sensitivity, although function-
ing properly,
may not be sensitive enough
to prevent bodily injury in some circumstances
. To augment your protection
against entrapment,
GTO
recommends
using some form of additional safety device.
When installed, contact sensors must
be mounted in compliance with UL 325, Underwriters Laboratories safety standard for gate operators. Review page 5 for
information about mounting requirements for safety edges ("contact sensors").
Refer to the sensor manufacturer’s instructions for
information about installing these devices on a vehicular
gate.
PLEASE NOTE:
Contact sensors are not
included with
the GTO/PRO® 3000/3200.
The GTO/PRO® 3000/3200 will ONLY accept accessory devices with normally open contact output.
Make sure the power switch to the operator
is turned off before connecting safety device
wiring to the terminal blocks. Unplugging
the transformer does not turn power to the
operator OFF.
Contact Sensor Input Connection:
Connect one of the OPEN EDGE contact sensor wires to the
COMMON (COM)
terminal and the other to the
OPEN
EDGE
terminal on the GTO/PRO®3000/3200 control board.
Connect one of the CLOSE EDGE contact sensor wires to the
COMMON (COM)
terminal and the other to the
CLOSE
EDGE
terminal on the GTO/PRO® 3000/3200 control board.
Activation of a contact sensor while the gate is in motion
will cause the gate to stop and reverse within 2 seconds.
Contact Sensors (safety edges)
If not installing a contact sensor skip to next section.
Although GTO strongly recommends the use of additional safety devices, we do not endorse any
specific brand names. Only use products that are certified and listed to be in compliance with any
applicable UL standards (United Laboratories) and national and regional safety codes.
