Now no one will be able to get into your room unnoticed! Assemble your own alarm with a set for research from 4M. Ensure a high level of security in your secret storage.
To collect and install alarms, you need the permission and help of adults. You will find all the details of the device in the set. Also take a small Phillips screwdriver and two AAA batteries. Strictly follow the instructions when learning the basic principles of electricity.
The principle of operation of alarm systems from 4M is very simple. The electrical circuit has two points that control the supply of current to the buzzer: a switch built into the battery case, and a plastic trigger plate inserted between the connecting plates. A string is stretched between the hole and the device. When the door opens, the string stretches and pulls out the plastic plate. Connecting metal plates come into contact with each other and start a current circuit. At this point, the alarm sounds. Spy spot!
This kit introduces the child to the basics of physics and electrical circuits in an interesting game form. An added bonus is a Do Not Disturb sign that can be hung on the door during covert operations.
