GTO 2502, 2550 Connecting Additional Safety Devices, Contact Sensors safety edges

Connecting Additional Safety Devices

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.

Call GTO Sales at 1-800-543-4283 for information on compatible

products for your specific application.

The GTO/PRO SW2502 will ONLY accept accessory devices with normally open dry contact output.

Contact Sensors (safety edges)

If not installing a contact sensor skip to next section.

PLEASE NOTE: Contact sensors are not included with the GTO/PRO SW2502.

The GTO/PRO SW2502 is equipped with built-in obstruction sensitivity. The opener is designed to stop and reverse the gate within 2 seconds when it comes in contact with an obstruction. However, obstruction sensitivity, although functioning 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 openers. Review page 5 for infor- mation 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.

Make sure the power switch to the opener is turned off before connecting safety device wiring to the terminal blocks. Unplugging the transformer does not turn power to the opener 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 SW2502 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 SW2502 control board.

Activation of a contact sensor while the gate is in motion will cause the gate to stop and reverse within two (2) seconds.
