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 (Underwriters Laboratories) and national and regional safety codes.
Call GTO Sales at 1-800-543-4283 for information on compatible
products for your specific application.
Make sure the power 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.
