FOR THE INSTALLER AND END USER
Mighty Mule gate operators utilize Dual Sense Technology
™
entrapment protection. Dual Sense Technology
™
is built
into every Mighty Mule and provides redundant methods of
entrapment protection for open and close gate directions.
In addition to Dual Sense Technology, every Mighty Mule
gate controller has provisions for the connection of additional
obstruction detection devices such as sensing edges and
photo beams.
These devices may be located where there is an increased
risk of obstruction. Refer to the diagram below. One or more
edge sensors may be located at the leading edge, bottom
edge, and post edge, both inside and outside of a vehicular
swing gate system.
Wiring to sensors must be located and arranged so the wiring
between the sensor and the gate operator is not subjected to
mechanical damage.
A wireless sensor such as one that transmits radio frequency
(RF) signals that promote safety shall be located where the
transmission of the signals is not obstructed or impeded by
building structures, natural landscaping or similar objects.

Entrapment and Obstruction Protection
Mighty Mules’s Dual Sense Technology
™
provides entrapment protection. Since all installations are different, you may need to
add photo beams or sensing edges to help prevent damage to vehicle or other items that could be hit by a moving gate.
Entrapment Alarm
The Mighty Mule Automatic Gate Operator is designed to stop and reverse the gate when the gate comes in contact with an
obstruction. Additionally, these operators are equipped with an audio entrapment alarm which will activate if the unit obstructs
twice while opening or closing. This alarm will sound for a period of 5 minutes, or until the operator receives an intended signal
from a hard wired entry/exit source (e.g. push button control or keypad). Turning the power switch on the control box OFF and
back ON will also deactivate the alarm. Wireless controls such as transmitters and wireless keypads will not deactivate the alarm.
