Product description
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 or alarm. Suitable
for detecting customers entering a shop, cars coming up a
driveway, etc. The IR beam is very strong. Distances over 25
feet can be monitored with this Kit. A 12VDC supply is
required to power the kit. A 12V wall adaptor is fine.
Provision has been made so that only one power supply
needs to be used to power both units. The relays in this kit
are rated to switch mains voltages.
