Important Safety Information
Mighty Mule gate operators utilize Dual Sense Tech-
nology™ entrapment protection. Dual Sense Technol-
ogy™ 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 lead-
ing 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 to the gate
operator for obstruction protection functions shall be
located where the transmission of the signals is not
blocked or impeded by building structures, natural
landscaping or similar objects.
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) and the gate returns to a fully
open or fully closed position. 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.
Entrapment and Obstruction Protection
Mighty Mules’s Dual Sense Technology
™
provides entrapment protection, even when properly adjusted. 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.
