ENFORCER 35ft Retro-Reflective Photoelectric Beam Sensor
SECO-LARM U.S.A., Inc.

LED Functions:
Red LED – When ON, indicates the sensor is powered
and the sensor is not triggered.
Yellow LED – When ON, indicates the sensor is properly
aligned with the reflector and the sensor is not triggered.
Sensing Range Adjustment Functions:
Min. Setting – The infrared power signal emitted by the
sensor is at its minimum or weakest.
Max. Setting – The infrared power signal emitted by the
sensor is at its maximum or strongest.
The purpose of this function is to adjust the infrared signal's
power to correspond to the distance between the sensor
and the reflector. The factory default setting is set at “Max.”
Note:
If the infrared signal is too strong, the sensor may not
trigger. If the infrared signal is too weak, the sensor
may be susceptible to false alarms.
Installation:
1.
Mount the reflector and the sensor so they face each
other (see pg. 2, "Mounting the Sensor").
2.
Connect power to the sensor (see pg. 2, "Wiring"). The
red LED (power) should turn ON. If the yellow LED is
ON, the sensor and reflector are aligned (although
some adjustment may still be necessary).
3.
Turn the sensing range knob to Max.
4.
To find the correct alignment, slowly adjust the angles of
the sensor (and/or reflector) up, down, left or right.
Note:
Correct alignment is reached when the yellow LED
turns ON.
Note:
If adjusting the sensor will not turn the yellow LED on,
the sensor is at the edge of sensing the signal, and
may not work properly.
Adjusting the Sensing Range:
After the sensor and reflector have been properly installed,
the next step is to adjust the sensor range (See Fig. 1).
Starting from the Max. position, slowly turn the knob
counter-clockwise until the yellow LED turns OFF. This
position represents the weakest point of the infrared signal

for this particular application. The setting of the sensing
range must be a little higher than this point, so turn the knob
clockwise somewhat from the weakest point. The ideal
setting is midway between the weakest point and Max.
Note:
When turning the knob counter-clockwise from the
Max. position, if the weak point is near the Max.
position then the knob should be set at Max.
Testing:
1.
Power up the sensor. Both LEDs should be ON.
2.
Pass the object to be detected between the sensor and
reflector. Both LEDs should turn OFF. This indicates
that the object has been detected.
Note:
If a shiny object, such as a chrome-plated item or
something with reflective tape, is within close
proximity of the path of the IR beam, the sensor may
not be able to detect the passing object. It may be
necessary to turn the sensing range knob counter-
clockwise until the desired setting is obtained.
Note:
Depending on the monitoring system used by the
gate motor, it may be necessary to use either the
N.C. output or the built-in 10kΩ resistor on the N.O.
output. Please refer to the gate operator manual or
the gate operator manufacturer for the preferred
monitoring method.
The E-936-S35RRGQ will not work with gate
operators that monitor using the "heartbeat" method.
