What is it?
This Kit uses an infrared beam to monitor door & passageways or any other area. When the beam is broken a relay is tripped which can be used to sound a bell trip an effect or cut off one. Suitable for detecting customers/victims, cars ect. The IR beam is very strong. Distances over 25 yards can be monitored with this kit. A single 12VDC wall adaptor is fine. Provision has been made so that only one power supply is needed to run both units.
Assembly Instructions
Materials Needed:
Kit 130
Soldering Iron
Solder
Wire Cutters
Instructions:
The Kit 130 uses some very nice quality
components, and ships with a printed circuit board. This makes them very easy to
put together and less likely to fail while in operation.
Skill Level
Please do not be afraid to attempt to assemble this kit! It is very easy to do,
even if you are an electronics novice! Work in a well lit area, and make
sure you have plenty of time to complete the project.

Prepare
Bend the restores and diodes in a U shape now to save time.
Start Receiver Board
I use a pair of helping hands available at Radio
Shack. It make the soldering process allot easier.
Install Z1
Z1 is 5V6 Diode. The writing is very small and a magnifying glass may me needed.
Most of the time it is the one packaged together with the IR Receiver. Make Sure
you put the stripe on the same side the stripe is on the board.
Install D1 & D2
D1 & D2 is 1N4148 Again the writing is small. Look
carefully. and match up the stripes.
Install D3 & D4
D3 & D4 are 1N4004 Power diodes. Strip must go
towards the Direction the arrow is pointing.
Reference- Restore Cross Reference Chart
Install Restores
Direction dose not matter but I like putting the tolerance stripe on the
right as a rule.
Install Capacitors
C4 & C5 are the larger ones and rated at 100uF
C1, C2 & C3 are rated at 10uF
All Five are Polarity sensitive and care must be take not to put in backwards.
the strip side is Negative and the boards
Positive hole is marked.
Install Q3 (Some times marked Q1)
Q3 is BC557
on the component itself it is sometimes marked like this though "C557B"
Make sure the flat sides on it and the board line up
Install Q2
Q2 is BC547
It too is marked "C547B"
and Flat sides must line up
Install L1 &RX1
L1 is the red led & RX1 is the IR receiver. I
raised the led up hi so it would poke out a box I am putting it into.
install L1 flat side towards the shaded side of the circle
install RX1 with the collector facing outwards
Install X1 & X2
X1 and X2 Are the power plug connectors.
and they only go in one way. :)
Install RL1
RL1 is the big blue relay.
it to only goes in one way
Install X3
X3 is the terminal block.
be sure the holes are facing out. Believe me it can happen (don't ask).
Receiver Board is now DONE
