Attach cover
– Attach transmitter cover, first.
– Confirm that receiver sensitivity attenuation LED stays
OFF. Place cover in position, but do not secure. A
"beep" sound will occur after five seconds. After this
signal, secure the receiver cover with screws.
Sensitivity allowance is automatically set when the
beep sound is initiated.
If tone alignment switch is left accidentally ON, tone
will stop when receiver cover is attached.
– If there is a continous "beep" sound, detach receiver
cover and re–adjust referring to Autogain lock function.

Operation check

(fig. 13)
After installation, alignment and auto–gain set, test op-
eration by walk testing the beam. Two methods may be
used:
Alarm LED only.
Alarm LED and sound check via tone alignment swtich.
If tone alignment switch is set to "ON", tone will stop
when cover is replaced but be effective for an audible
test of operation for five minutes after auto–gain is
locked.

Functions description

Four channel frequency selection (fig. 14)
The beam pairs may be set at various frequency levels to
avoid crosstalk between units which are stacked, in–line,
or other configurations which have the potential of spill–
over transmission from one beam to another. Set the
frequency level as illustrated. (fig. 14)
MAKE SURE BOTH TRANSMITTER AND RECEIVER
OF PAIR ARE SET TO THE SAME CHANNEL! Paired
TX / RX will not set up unless set at the same channel.
– The use of a voltmeter for alignment is advised to en-
sure highest level of stability.
– Upper and lower beams should be the same model
type in stacked configurations.
Beam power selection
This option allows field selection of the appropriate beam
intensity relative to the application. For distances signifi-
cantly less than the specified protection distance, the
beam intensity should be reduced to eliminate potential
reflection problems. For zones reaching maximum
protection distance, the beam level should be set to the
highest level.
For indoor applications where there is a greater
chance of reflections, the setting should be LOW.

Auto–gain lock function (fig. 15)
The auto–gain lock serves to standardize the respon-
siveness and tolerance level of the units regardless of
varying distance in an installation.
– The situations fig. 15 have exactly the same tolerance
and responsiveness levels even though the distances
are different.
A "beep" tone is issued from the receiver approximately
five seconds after the cover is put into position. This tone
indicates the Auto–gain has been set. Refer to the chart
below.

Tone indicator
This feature provides audible testing of signals for the fol-
lowing items.
Response time changeover function (fig. 8)
This feature can be used to alert the response time of the
beam to best fit the application. Exercise caution in using
the 700msec setting. Non–detection of fast moving hu-
man could result.
Turning the pot up
voids the UL listing.
Environmental module (fig. 10)
The environmental signal is initiated if the beam recep-
tion level is reduced by approx 50% or more. The module
"watches" for a gradual degration of the beam reception
which is indicative of extremly poor weather conditions.
NC or NO signal output is selectable. (Contact capacity
30V (AC/DC) or less)
Alarm memory function
The alarm memory LED indicates which sensor has trig-
gered when two or more sensors are placed on a zone.
An audible tone in addition is optional. Reset can be auto-
matic or manual.

If alarm memory function is not used, set the
