s2sap Posted June 10, 2018 Share Posted June 10, 2018 I need to move a contact door alarm up abut 12 inches on the door frame and need to add a bit of cable to the existing alarm cable which is Red & Blue Joined : Black & Yellow Joined : Green Disconnected. The system is run by a 12v lorry battery. I need to fix this quickly but dont have similar cable. The closet type of cable I have to hand that I think would work is twin core lightweight 240v cable ( probably only 3 or 5 amp ) Would this be potential for joining to the existing alarm cable Thanks In Anticipation Link to comment Share on other sites More sharing options...
MikeSharp01 Posted June 10, 2018 Share Posted June 10, 2018 Yes its all very low voltage / low current stuff, provided you get the correct cores connected up. You may have an anti tamper connection which means that once you break the wires the alarm will go off, and you will have to silence it, but if not its straight forward to extend it.

ProDave Posted June 10, 2018 Share Posted June 10, 2018 Use some telephone or cat5 cable instead. The colours will be different but as long as the same cable ends up in the same place that won't matter. Link to comment Share on other sites More sharing options...
