Hi all
Can anyone advise whether there is a standard for wiring of intruder alarms? Looking at my existing (rapidly failing) install, red and black cores are used for power to passives - seems sensible. Checking the installation manual for a panel ordered this afternoon, this has two of the other cores (white and green) for power, with red and black used for the alarm trigger pair. I know it won't make a scrap of difference to the operation, but if there is a standard out there I am quite prepared to follow it.
TIA
Phil
