Connecting Additional Safety Devices
The Mighty Mule Gate Opener
®
is equipped with built-in obstruction sensitivity. The opener is designed to stop and reverse
the gate approximately 2 seconds when it comes in contact with an obstruction. However, obstruction sensitivity, even when
properly adjusted, may not be sensitive enough to prevent bodily injury in some circumstances. To augment your protection
against entrapment, GTO suggests using safety edge sensors or photoelectric sensors. When installed, safety edge sensors (or
photoelectric sensors) must be mounted in compliance with UL 325, Underwriters Laboratories safety standard for gate
openers. Review page 4 for information about mounting requirements for safety edges ("contact sensors") and photoelectric
sensors ("non-contact sensors").
Refer to the sensor manufacturer’s instructions for information about installing these devices on a vehicular gate.
Make sure the control box power switch is OFF before connecting safety device wiring to the terminal blocks.
Insert the safety device wires into the CLS EDG terminal on the FIRST OPERATOR terminal block for the gate closing
mode. Connect the safety device ground wire to the GRN terminal. Connect the safety device wires for the gate opening
mode to the OPN EDG terminal in the same manner.
Repeat the above procedure for the SECOND OPERATOR terminal block.
PLEASE NOTE: Safety edge sensors and photoelectric sensors are neither included with nor required for the Mighty Mule
Gate Opener
