As specified by Gate Operator Safety Standard, UL 325

(30A.1.1), automatic gate operators shall have an inherent

entrapment sensing system, and shall have provisions for,

or be supplied with, at least one independent secondary

means to protect against entrapment. The Mighty Mule

200 utilizes Type A, an inherent (i.e., built-in) entrapment

sensing system as the primary type of entrapment

protection. Also, the Mighty Mule 200 has provisions

for the connection of Type B2 protection to be used as

the secondary type of entrapment protection, and is

recommended.

1. For gate operators utilizing a contact sensor (e.g.,

safety edge sensor– Type B2) in accordance with UL

325 (51.8.4 [i]):

A. One or more contact sensors shall be located at

the leading edge, bottom edge, and post edge, both

inside and outside of a vehicular swing gate system.

B. A hard wired contact sensor shall be located and its

wiring arranged so that the communication between

the sensor and the gate operator is not subjected to

mechanical damage.

C. A wireless contact sensor such as one that

transmits radio frequency (RF) signals to the gate

operator for entrapment protection functions shall be

located where the transmission of the signals is not

obstructed or impeded by building

structures, natural landscaping or similar

obstruction. A wireless contact sensor shall

function under the intended end-use conditions.

Secondary Means of Protection Against Entrapment

ENTRAPMENT ALARM (UL 325; 30A.1.1A)

The Mighty Mule 200 Automatic Gate Operator is designed to stop and reverse within 2 seconds 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 hardwired 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.
