What can you do with this kit?
Create your own police siren or warning alarm. Have fun creating this 29 piece sound and light kit with a red and blue spinner and buzzer siren. Trigger the alarm with the switch and watch it go off to alert everyone. You could even combine with the maze challenge (Order Code A52JB) for a truly alarming experience.

What does this teach?
Learn electronics and circuit design. The Connex 38823N alarm kit is a good example to show redundancies in a system and how components work in parallel. Both the siren and spinner are connected to the switch and power supply but not to each other – this is a parallel connection. Therefore if one of the wires connecting the spinner to the circuit is not there the siren still sounds but the spinner does nothing and if one of the wires leading to the siren is not connected the siren will not sound but the spinner is unaffected. For those who want to explore how circuits work in series as well the Connex maze challenge is a great introduction. In alarms the alternatives or redundancies are a safety measure so there is a backup in case one is not working.

Mix and match with Connex
Be creative with your kit by mixing components with other Connex kits (take care to match power requirements). No soldering is required with this kit, all the components can be connected using the supplied wires fitting into the springs on the board. No need to worry about losing pieces, the kit comes in a box that doubles as a base to assemble the kit on and a storage box when you tidy it away. This kit requires two AA batteries (sold separately Order Code <L43AL>).

This kit should be used with adult supervision and assistance and is suitable for children aged 8 and over.

Rated 4 out of 5 by from Alarm System Bought for 8 year old boy. Built with Grandad's help. Had a few problems with wires becoming disconnected but were able to repair. Grandson seemed pleased with this gift.
