ENFORCER Long-Range Barrier Sensors
ENFORCER Long-Range Barrier Sensors are ideal for protecting indoor or outdoor areas
separated by long distances. They feature reliable photobeam technology with a choice of
four programmable beam frequencies that provide superior perimeter protection by
eliminating crosstalk and interference when multiple units are used. False alarms caused
by animals, falling leaves, poor weather, or other sources are minimized by programming
the alarm output trigger operation.
ENFORCER Long-Range Barrier Sensors work in even the most extreme conditions. A
built-in heater automatically turns on and off depending on the outside temperature. An
environmental control system senses a slow degradation in beam strength when weather
conditions worsen to help prevent false alarms.
Installation and alignment is quick and easy with the ENFORCER Long-Range Barrier
Sensors. They come with swiveling heads that allow them to be mounted along the same
wall or on opposite walls, as well as provide for easy alignment of the beams between the
transmitter and receiver.

Installation – Choosing a Location:
When used outdoors, place the Long-Range Barrier Sensor under a roof or
shelter. This will reduce the chance of false alarms caused by rain or snow.
To prevent erratic operation and/or false alarms:
Do not mount near trees, bushes or
other leafy vegetation. Wind could
cause leaves or similar objects to fly or
wave into the beams (see Fig. 1).
Do not mount where water might run
off the roof and break the beam
(see Fig. 1).
Do not mount where the units could be
splashed by water or mud.
Do not let sunlight or any direct beam
of light shine directly on the sensor. If
unavoidable, mount in a way that the
transmitter – not the receiver – faces
the sun (see Fig. 2).
Mount the sensor so that the wires are
placed at the bottom. If the wires must
be placed on top, seal the opening
with silicone.
Do not mount in such a way that the
terminal block of one unit is at the top
and the other is at the bottom
(see Fig. 3).
Do not mount where animals or other
objects could accidentally break the
beams.
Do not mount near reflective surfaces,
as this could prevent the sensor from
working properly.
Do not mount where the unit could be
suddenly exposed to a bright light, such
as a floodlight or a passing
automobile’s headlight.
IMPORTANT: Do not connect to power until the sensor has been completely installed
and the installation has been double-checked.

Fig. 2 – Orientation to the sun
Do not let sunlight or any direct beam of light shine
directly on the sensor. If unavoidable, mount in a
way that the transmitter – not the receiver – faces
the sun.
Fig. 3 – Orientation of the terminal
blocks
Mount so that the
terminal blocks of
both units are at the
top or both are at
the bottom. Do not
mount in such a
way that the
terminal block of
one unit is at the top
and the other is at
the bottom.

1. Find a suitable location.
a. The transmitter and receiver can be mounted at any angle as long as they are
parallel to each other and directly facing each other, and as long as the wires come
out of the same ends of both units (see Fig. 3).
b. If using multiple curtain sensors, be sure to set each for a different frequency
(see pg. 11).
c. The transmitter and receiver must not be separated by more than 190ft (60m)
outdoors or 380ft (120m) indoors.
2. Mount the transmitter and the receiver in such a way that surface-mounted wires do not
come out from above the units. This is to prevent water from entering via the wire holes.
If this is unavoidable, use silicone to completely cover the area where the wires come
out the holes to prevent water from entering
3. Once a suitable mounting location has been
found, remove the covers of the end caps
and locate the three mounting holes (see
Fig. 10). Using these holes as a template,
mark their location on the wall with a pencil.
4. Connect the wires (see pg. 9) before
permanently mounting the units to the wall.
Installation – Running the Wires
1. Run six wires (1 x power, 1 x ground, 2 x alarm signal, and 2 x tamper switch) from the
alarm control panel to the receiver of the sensor. Shielded cable is strongly suggested.
2. Run four wires (1 x power, 1 x ground, and 2 x tamper switch) from the alarm control
panel to the transmitter of the sensor. Shielded cable is strongly suggested.
Note: It may be more convenient to connect the transmitter’s power and tamper wires to
the receiver’s power and tamper wires.
3. If burying the wires is required, make sure to run them through electrical conduit.
Shielded cable is strongly suggested.
4. If the wires are run along the wall, the use of armored cable is strongly suggested.

ENFORCER Long-Range Barrier Sensors
Installation – Connecting the Wires
1. Unscrew and pull the end cap off the side of the receiver with the terminal block
(see Fig. 11).
2. Run the wires through the rubber wire hole in the top corner of the back of the end cap.
3. Program the receiver (see pg. 11).
4. Replace the end cap. NOTE: End cap must be off when aligning the sensor.
5. Use a screwdriver to tighten the screws holding the end cap in place.
1. Unscrew and pull the end cap off the side of the transmitter with the terminal block
(see Fig. 12).
2. Run the wires through the rubber wire hole in the top corner of the back of the end cap.
3. Program the transmitter.
4. Replace the end cap. NOTE: End cap must be off when aligning the sensor.
5. Use a screwdriver to tighten the screws holding the end cap in place.

1. To align the beams, loosen the swivel screw and adjust the beams to face each other.
Connect the power to the receiver and transmitter. If the beams are not aligned, the red
LED on the receiver will light ON (see Fig. 13).
2. For audible confirmation in addition to the LED, make sure jumper JP1 is plugged in on
the receiver’s circuit board. If the beams are not aligned, the receiver’s buzzer will
sound. To disable this feature, remove JP1 (see Fig. 14).
3. Once the beams are aligned, the red LED will turn off and the buzzer will not sound.
Programming the Trigger Mode
1. The default detection method is when any 2 adjacent pair of beams is broken, or when
any single pair of beams are broken more than 2 seconds (see Fig.19).
2. The latter (any single pair of beams broken) detection function can be disabled when
the JP2 jumper is removed.
