SPECIAL FEATURESSPECIAL FEATURES
The Obstruction Sensor detects obstructions
in the path of the traveling gate. The Trim
Pot for the Obstruction Sensor adjusts the
sensitivity level that triggers the Sensor.
When the Obstruction Sensor detects an
obstruction it will:
1. Stop the gate’s movement and reverse it
momentarily.
2. Bring the gate to a resting position.
3.
Disable the Hold Open Timer feature until the
Gate Operator receives a new command.
If another obstruction is detected before the
gate reaches either limit it will:
1. Stop the gate’s movement.
2. Bring the gate to a resting position.
3. Disable the Gate Operator.
UL325 standard requires an audio alarm to
go off after two consecutive entrapment
events
sensed by the Inherent Entrapment
Protection of the Gate Operator.
The audio alarm will sound for a period of 5
minutes or until the “Stop” Button is
pressed (see page 8 for remote installation
of a “Stop” Button).
Intelligent Obstruction Sensor
(Primary Entrapment Protection)
Turning the Trim Pot clockwise
increases the sensitivity.
Turning the Trim Pot counter-
clockwise decreases the sensitivity
