The Three Investigators - Security System

Caught! Secrets have never been better protected than with The Three Investigators security system. No one gets through this light barrier unnoticed. The detailed instructions explain to children aged eight and up how to properly set up and use the alarm system: Two transmitters emit light beams. They are activated and aligned with the two receivers in the base station. If a person now passes through the light barrier, the alarm sounds. Quickly insert batteries, read tips and tricks, and transform the children's room into a high-security zone. This hiding place is safe!

Contents: Two transmitting stations, one base station, instructions.

Additional material required: 6 x 1.5-volt batteries type LR03 (AAA, Micro). Small Phillips screwdriver.
