Thank you for purchasing our photoelectric beam sensor.
This sensor will provide long and dependable service
when properly installed.
Please read this Instruction Manual carefully for correct
and effective use.
This sensor is designed to detect intrusion and to
initiate an alarm; it's not a burglary–preventing
device. Vanderbilt is not responsible for damage, injury
or losses caused by accident, theft, Acts of God
(including inductive surge by lightning), abuse, misuse,
abnormal usage, faulty installation or improper
maintenance.
Product Description
The Vanderbilt photoelectric beam sensor (IS433, IS434
and IS435) consists of an infrared Transmitter and
Receiver.
It's designed to be "AND" gated – an alarm is initiated only
when two stacked beams are simultaneously interrupted.
An alarm is not initiated when insects or falling
leaves break one beam only.
In addition, four channels of beam frequency are
available to prevent cross–talk when multiple units
are stacked or multiple units are lined up.

thread the cable through, see fig. 4C and attach
to the mounting plate.
After wiring is completed, adjust alignment, check
operation and fit the cover.
Sealing is not required for unit surround due to
rain–proof construction.

Fix pole mounting plate to pole with pole bracket.
Detach cover, and remove mounting plate from
sensor body.
Loosely insert 2 pcs. of M4x10 screws in pole mounting
plate and fix sensor mounting plate on them.

it. Secure the plate with 4mm screws (figure 4B).
Fill the opening between grommet and wire
with sealing compound.
Remove knockouts on the rear of the unit and
thread the cable through, see fig. 4C and attach
to the mounting plate.
After wiring is completed, adjust alignment, check
operation and fit the cover.
Sealing is not required for unit surround due to
rain–proof construction.

Back to Back Pole Mount and Right
Angle Pole Mount
First, fix the pole mounting plate for the 1st unit.
Fit the 2nd unit pole bracket under the 1st unit pole
mounting bracket and fix the 2nd pole mounting plate
up side down.
Open grommet on mounting plate and pull wire through
it. Secure the plate with 4mm screws (figure 4B).
Fill opening between grommet and wire with sealing
materials.
Remove knockouts on the rear if the unit and thread the
cable through, see fig. 4C attach the mounting plate.
After wiring is completed, adjust alignment, check
operation and attach cover.
Sealing is not required for unit surround due to
rain–proof construction.
Position of installations
Adjustment (fig. 6)
Using the adjustments, the lens can move horizontally
(90 degrees) and vertically (10 degrees) allowing the
unit to work in all directions (figure 6A I 68 I 6C).
Cautions on installation
– Avoid overhead power cables.
– When installing indoors, wiring procedures similar to
those for telephones or intercoms are acceptable.
Outdoor wires should be placed inside conduit or
underground cable / metal shielded cable should be
used.

Maximum wiring distance when two or more sets are
connected is the value above divided by the number
of sets.
The signal line can be wired to a distance of up to
1000m with AWG22 (dia 0.65mm) telephone wire.
Response Time
Adjust response time as follows. The longer response
(fig. 5B)
times reduce the possibility of false alarms from birds
and loose objects, but too longer time will reduce the
detection of Human beings, so it is necessary to test
the setting to achieve adequate detection in each
installations environment.

Units should be tested on a regular monthly basis. To test,
walk in front of Receiver and watch to see if the walk test

Unreasonable longer response time may cause
undetection of human being.
Turning the pot up to increase the response
time voids the UL listing.
(fig. 10)
Supply power with cover removed.
Set the same beam channel on Transmitter and
Receiver. (Channel 1 set at factory)
Align Transmitter lens to Receiver lens.
The view finder is located between the 2 lenses.
Look through view finder on either side and line–up
optics horizontally and vertically until the opposite
unit is visible.
(Move the metal part to change the horizontal angle.)
Further, fine tune until receiver attenuation LED is OFF.
When the unit is fitted outdoors, fine tune with
attenuation sheet positioned on the receiver optics
until the Receiver attenuation LED is OFF.
When the unit is fitted outside,it is advisable to use
a test meter to optimize the alignment adjustment.
You can confirm the beam signal level by inserting
a tester meter in monitor jack of Receiver.
The voltage on the reference shows attenuation
sheet conditions.
When multi–stacked protection or inline protection is
set up, it is advisable to adjust beam alignment with
a test meter in order to optimize alignment, together
with making use of beam frequency change function.
When stacked protection is set up, both the upper
and lower sensors should be the same model
number types.
Set Transmitter and Receiver at the same channel.
Refer to the figures and set the beam channel when
two or more units are installed in stacked protection or
in line protection.
