ENFORCER Curtain Sensors
When used outdoors, place the curtain 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:
Wind will not directly cause false alarms, but
could cause leaves or similar objects to fly
into or otherwise obstruct the beams. Do
not mount near trees, bushes, or other leafy
vegetation (see Fig. 1).
Do not mount where water running off the
roof might break the beam (see Fig. 1). The
sensor and beams must be sheltered.
Do not mount near reflective surfaces, as this
could prevent the sensor from working
properly.

Important:
Do not connect to power until the sensor is completely installed and the installation has been
double-checked.

Choosing a Location:
SECO-LARM U.S.A., Inc. 3
ENFORCER Curtain Sensors
Do not mount where the transmitter or
receiver could be splashed by water or
mud.
Do not mount where unit could be
suddenly exposed to a bright light,
such as a floodlight or a passing car’s
headlight.
Do not let sunlight or any direct beam of
light shine directly on the curtain beam
sensor. If unavoidable, mount so the
transmitter, not the receiver, faces the
sun (see Fig. 2).
Do not mount where animals or other objects could accidentally break the beams.
Choosing a Location, continued:
Fig. 2: Orientation to Sun
The sensor beam frequency can be set at different
frequencies on-site to avoid interference from multiple
curtain sensors nearby. To select between three different
beam frequencies, set the jumper of the transmitter side
and receiver side (see Fig. 3).
Note:
1. If the frequency is changed, power must be cycled on the transmitter and receiver
after the new frequency is selected.
2. Both the transmitter and the receiver of each pair must be set to matching
frequencies to work together correctly.
1. Find a suitable location (see Fig. 1):
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. 4).
b. If using multiple curtain sensors, be sure
to set each for a different frequency (see
Selectable 3-Channel Beam Frequency
above).
c. The transmitter and receiver must not be
separated by more than 50 feet indoors
and 25 feet outdoors.

ENFORCER Curtain Sensors
Run four wires (2x power and 2x alarm signal) from
the alarm control panel to the receiver of the curtain
sensor. Shielded cable is strongly suggested. See
Table 1 to the right for maximum wire length. Two
power wires must also be run to the transmitter.
It may be more convenient to connect the transmitter’s two power wires to the receiver’s power
wires. In this case, run six wires to the receiver: two wires to the power source, two for the alarm
signal, and two to the transmitter.
Note:
1. If burying the wires is required, make sure to run them through electrical conduit.
Shielded cable is strongly suggested.
2. If the wires are run along the wall, using an armored cable is strongly suggested.
2. Mount the transmitter and the receiver so that the
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 (see Fig. 4).
3. Once a suitable mounting location has been found,
remove the covers of the end caps (see Fig. 5), and
pull the tamper buttons out of the end caps (one per
transmitter or receiver) and locate the mounting holes.
Using these holes as a template, mark their location on the wall with a pencil.
4. Connect the wires (see Figs. 6 and 7) before permanently mounting the units to the wall.

b. Run the four wires (or six wires, if connecting
the transmitter’s power wires to the receiver)
through one or more of the three ground
knockout holes in the end cap near where the
tamper button wires run, and connect them to
the wiring block (see Fig. 6).
c. Program the receiver (see Table 2 on pg. 6).
d. Carefully push the PCB back into the case
and reinsert the end cap.
e. Reinsert the cap over the tamper button and small tamper cap.

For best results when the curtain sensor is mounted outdoors, remove the transmitter lens caps
(DO NOT remove the receiver lens caps!).
To remove the lens caps (see Fig. 8):
1. Slide the PCB out of the transmitter (see
“Connecting the Wires” on pg. 5~6).
2. Carefully pull the lens cap off of all the lenses
(4 for the E-9611-2x25, 8 for the E-9622-4x25,
12 for the E-9644-6x25, 16 for the E-9660-8B25, 20 for the E-9680-10B25).
3. Slide the PCB back in (see “Connecting the Wires” on pg. 5~6).
2. Transmitter:
a. Pull the end cap with the red wire leads off the transmitter, and slide the PCB out far
enough to expose the wiring block.
b. Run the two power wires through one or more of the three round knockout holes in the end
cap near where the tamper button wires run; connect them to the wiring block (see Fig. 7).
c. Program the transmitter (see Table 2 below).
d. Carefully push the PCB back into the case and reinsert the end cap.
e. Reinsert the cap over the tamper button and small tamper cap.
Note:
1. Screw the wires tightly to avoid slipping off the terminals, but not so tight that they break.
2. Unused terminal screws should be tightened.
3. Grounding may be necessary, depending on the location.

Several units can be connected together in parallel to the same power supply output and alarm
input of an alarm control panel.
Please reference Fig. 6 & 7 for terminal blocks.
1. Temporarily mount the transmitter and receiver to where they are expected to be mounted, so
the mounting position can be changed if necessary.
2. Connect the transmitter and the receiver.
3. Once it is powered up, test the curtain sensor by breaking two adjacent beams or any single
beam (depending on programming).
4. The curtain sensor also has red LEDs which can be used for testing purposes (see Table 2).
5. After the curtain sensor is tested and aligned, permanently mount it.
6. After it is mounted, test the curtain sensor again.

The receiver and the transmitter both have a tamper switch on one end to protect against someone
attempting to open the unit. However, there is no separate tamper output to the alarm control
panel. Instead, the alarm output is triggered if the cover of the end cap with the tamper button is
removed, if the transmitter or receiver is moved out of alignment, or if power is disconnected.
