Alarm Wire Extend / Replace

[deemo]

Hi

I'm sure this is possible but just wanted to double check with the experts.

If i have a section of alarm wire i'd like to replace or if i want to extend can i

1) Strip wires, put together and use insulation tape to make connection

2) Am i better using a Junction box like this

For those who don't click on links it's just a 6 way small rectangular box supposed to be for alarms

I need to also maybe test existing cables that they not damaged is there a cheap and easy device or something i can do for this

Thanks

You can get a cheap mutli meter on ebay, that should be okay about £5.

but you do get what you pay for, but should be adequate to do some continuity tests and measure resistances etc without breaking the bank.
