Prevent anyone from getting passed you without your noticing it! You won't have to lay any cables or install light barriers: with the Franzis Build Your Own Alarm System Kit you can build your own small security device.
The Kit includes all the components required to build it without much effort, you just solder the components to the pre-assembled circuit board. Even if you do not have any experience in soldering it won't be a problem! The set-up is simple and the detailed instructions explain how to, step by step.
How it works: The Franzis alarm system responds to variations in air pressure that arise when doors or windows are opened or closed. Without any complex installations, unwanted visitors can now be caught in the act.
The Franzis alarm system comes with additional alarm inputs and outputs (one of each kind) so you can freely attach further alarm devices or sensors.
You will need: A soldering iron, solder, a wire cutter. For operating the device: three 1.5 V AA batteries (not included).
Warning! Not suitable for children under 14!
