ENFORCER Twin Photobeam Detectors

SECO-LARM U.S.A., Inc.
Run a cable from the alarm control panel to the photobeam sensor. If burying the cable is
required, make sure to use electrical conduit. Shielded cable is strongly suggested. See Table 1
for maximum cable length.
The photoelectric beam lens can be adjusted horizontally ±90°, and vertically ±5° (see fig. 2).
This allows much flexibility in terms of how the transmitter and receiver can be mounted.
See fig. 3.
Install at a distance of 32" to 39" (80 to 100 cm) above the ground for most situations. See fig. 3.

Note (1):
Max. cable length when two or more sets are connected is the value shown in
Table 1 divided by the number of sets.
Note (2):
The power line can be wired to a distance of up to 3,300ft (1,000m) with AWG22
(0.33mm

) telephone wire.
Wiring the Transmitter – Wall Mount:
3.
If the sensor wiring is run along the surface
of the wall – There are two plastic
knockouts on the back of the sensor unit,
one on top and one on bottom. Break out
the appropriate knockout, and pull the
wiring through the knockout. Then run the
wiring through the hole near the top of the
sensor unit so it comes out the front. Using
two of the included mounting screws, attach
the mounting plate to the wall. Then
reattach the sensor unit to the mounting
plate, connect the wires, and snap on the
cover. See fig. 6.
1.
Remove the cover. Remove the screw under
the lens unit in order to detach the mounting
plate. See fig. 4.
2.
If the sensor wiring comes from inside the
wall – Break a hole in the mounting plate’s
rubber grommet, and pull the cable through
the grommet’s hole. Then run the cable
through the hole near the top of the sensor
unit so it comes out the front. Using two of the
included mounting screws, attach the
mounting plate to the wall. Then reattach the
sensor unit to the mounting plate, connect the
wires, and snap on the cover. See fig. 5.
