III. After Installation
1. Attach the warning signs (included) to each side of the
gate to alert the public of automatic gate operation. It is
your responsibility to post warning signs on both sides
of your gate. If any of these signs or warning decals
becomes damaged,
illegible, or missing, replace them immediately.
Contact Nortek Security and Control for free
replacements.
2. The gate is automatic and could move at any time,
posing serious risk of entrapment. No one should be in
contact with the gate when it is
moving or stationary.
3. Do not attempt to drive into the gate area while the gate
is moving; wait until the gate comes to a complete stop.
4. Do not attempt to “beat the gate” while the gate is
closing. This is extremely dangerous.
5. Do not allow children or pets near your gate. Never let
children operate or play with gate controls. Keep the
remote control away from children and unauthorized
users; store controls where children and unauthorized
users do not have access to them.
6. KEEP GATE SYSTEMS MAINTAINED. Always turn power
to operator OFF before performing any maintenance. See
page 28 for maintenance procedures.
7. To operate this equipment safely, YOU must know how to
disconnect the operator for manual gate operation (see
page iii). If you have read the instructions and still do not
understand how to disconnect the operator, contact the
Mighty Mule Service Department.
8. Disconnect the operator ONLY when the power is
TURNED OFF and the gate is NOT moving.
9. Make arrangements with local re and law
enforcement for emergency access.
10. Distribute and discuss copies of the
IMPORTANT SAFETY INFORMATION
section of this manual with all persons
authorized to use your gate.
11. IMPORTANT: Save these safety instructions. Make sure
everyone who is using or will be around the gate and
gate operator are aware of the dangers associated
with automated gate systems. In the event you sell the
property with the gate operator or sell the gate operator,
provide a copy of these safety instructions to the new
owner.
Should you need a replacement manual, a copy can
be obtained by downloading one from the Mighty Mule
web site (www.mightymule.com), by contacting Nortek
Security and Control by calling 1-800-543-4283 and
requesting a duplicate copy.
FOR THE INSTALLER AND END USER 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.
