3.2 Wiring lengths
Each value in the table below represents the maximum wiring distance (one way) when using
DC12V or DC24V power source. When installing 2 or more sets on one wire, obtain the maxi-
mum length by dividing the maximum wire length listed below by the number of sets installed.
When using a thicker wire gauge (19 AWG or 0.9 mm wire), use relays for connection. It is not
possible to connect directly to the terminal inside of the detector.

CAUTION!
Ensure that proper safety precautions such as powering off the device, and/
or protecting the wire from outdoor elements is adhered to. Failure to do so
may result in personal injury, or damage to the device.
4 Beam spread
The optical path forms as the beam spreads when it is reflected against an adjacent reflec-
tive surface such as a wall. Reflection of this beam may prevent a true alarm condition even if
the beam from the transmitter to the receiver is interrupted. The beam from another detector
may affect and cause malfunction when a multiple number of detectors are installed.The beam
spread angle of this unit is about ±1°. Refer to the figure and table below to determine the
installation position and distance to be used when installing a multiple number of units.

6 Optical axis alignment
You can align an optical axis two ways: with a level LED and/or with a
tester.
6.1 Using an optical alignment
6.1.1 Coarse adjustment
Use the horizontal adjustment turntable and the vertical adjustment screw to
aim the optics at the detector scope view finder.

6.2 Using a tester
6.1.2 Fine adjustment
Insert the volt meter tips into the test terminals of the receiver to check the
voltage. If the value is 1.9V or more, the adjustment is completed. If it is less
than 1.9V, adjust the transmitter and receiver until 1.9V or more voltage is
obtained. A voltage level of 2.2V or above is ideal.

7 Operational check
Perform the following to test the operation of the detector.
7.1 Alarm operation
1.
To check the alarm operation, walk along the assumed intrusion path near
the transmitter and receiver, in a "zig-zag" pattern to disrupt the beam
signal.
2.
Check that the alarm LED lights up and the control panel receives the
alarm signal when the beam is interrupted.
7.2 Tamper operation
1.
Check that the control panel receives a tamper alarm when either of the
transmitter and/or receiver covers are open.
8 Maintenance
Inspect the device regularly for proper functionality. Check the following:
–
Tester voltage level is above 1.9V.
–
Power input voltage is between DC 10.5V and 28V.
–
Alarm and tamper outputs are functional.
