Mounting the Curtain Sensor
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 multiple curtain sensors are set up to form longer or
deeper barriers, mount so that one transmitter is not
facing multiple receivers (see fig. 5).
c. The transmitter and receiver must not be separated by
more than the maximum range (see fig. 6).
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 (see fig. 4).
3.Once a suitable mounting location has been found,
remove the small covers of the end caps, 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. 7 and 8) before
permanently mounting the units to the wall.
Running the Wires
Run four wires (2 x power and 2 x alarm signal) from the
alarm control panel to the receiver of the curtain sensor.
Shielded cable is strongly suggested. See Table 1 for
maximum wire length. Two power wires must also be run
to the transmitter.
It may be more convenient to connect the two power
wires of the transmitter 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:
If burying the wires is required, make sure to
run them through electrical conduit. Shielded cable
is strongly suggested.
NOTE:
If the wires are run along the wall, the use of
an armored cable is strongly suggested. (See
“Mounting the Curtain Sensor,” point 2, for further
considerations.)
Connecting the Wires
1.Receiver:
a.Pull the end cap with the red wire leads off the
receiver, and slide the printed circuit board out
far enough to expose the wiring block.
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 round
knockout holes in the end cap near where the
tamper button wires run, and connect them to the
wiring block (see figs. 7 and 8).
c.Program the receiver (see Table 2).
d.Carefully push the printed circuit board back into
the case and reinsert the end cap.
e.Reinsert the cap over the tamper button and
small tamper cap.
2.Transmitter:
a.Pull the end cap with the red wire leads off the
transmitter, and slide the printed circuit board 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, and
connect them to the wiring block (see fig. 8).
c.Program the transmitter (see Table 2).
d.Carefully push the printed circuit board back into
the case and reinsert the end cap.
e.Reinsert the cap over the tamper button and
small tamper cap.

Note:
Screw the wires tightly to avoid slipping off
the terminals, but not so tight that they
break.
Note:
Unused terminal screws should be tightened.
Note:
Grounding may be necessary, depending on
the location.
Removing the Lens Caps (for outdoor
use only)
For best results when the curtain sensor is mounted
outdoors, remove the transmitter lens caps.
(Important: DO NOT remove the receiver lens caps!)
To remove the lens caps (see fig. 9):
1.Slide out the circuit board of the transmitter (see
the “Connecting the Wires” section for the
procedure).
2.Carefully pull the lens caps off of all the lenses
(8 for the E-9622-4B25, 12 for the E-9644-6B25,
16 for the E-9660-8B25, 20 for the E-9680-10B25).
3.Slide back in the printed circuit board (see the
“Connecting the Wires” section for the procedure).
