ENFORCER Long-Range Barrier Sensors
6 SECO-LARM U.S.A., Inc.
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.

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.
