• Always switch the frequencies TWO channels apart when
stacking units on top of one another. (See following
example.) The upper unit is set on channel 1 while the
lower is on channel 3, channels 2 and 4 could have also
been used.
Note>>
• Do not attempt to install this product with any other
photoelectric detector. It may cause the detector to
fail or not respond to movements.
If the receiver of this product receives the beam from
the wired photoelectric detector, it may cause false
alarms.
• In case that you install the battery operated
photoelectric detector with Optex hard-wired
photoelectric detector at the same site, ensure that
the hard-wired transmitter cannot affect any other
battery operated receivers for avoiding cross talk
between photoelectric detector.

4-1 FUNCTION
The 4 channel beam frequency selector can be used to avoid
unwanted crosstalk that can occur when using multiple
photoelectric detectors for long distance or beam stacking
applications.
• To select between 4 separate beam frequencies, use the
switch provided.
• Make sure the receiver and transmitter that are facing each
other are set to the same channel.
• More than double stacked application is not possible.

a) Double stacked protection
Since Receiver B may receive the infrared beam from Transmitter
A, select the frequencies as shown in the figure above.
(In the figure, each number in the square indicate a channel numbers.)
Since Receiver C may receive the infrared beam from Transmitter
A, select their frequencies as shown in the figure above.
c) Double stacked long distance protection
• More than double stacked application is not possible.
