  1. Do Fire Alarm Circuits Need To Be Segregated From All Other Circuits

    mattpatterson replied to james.wilson's topic in General Fire Alarm Queries
    Scotmod. What part of 7671 are you quoting on this? Previously I have run mains cabling and fire alarm/ELV/data in the same tray but with a divider to separate them. This was agreed by everyone and signed off by the Clients consultant. in the NON-mains side, I was under the impression that the voltages in fire alarm, data and security (Power Over Ethernet - in our case) were so low that they would not cause any interference with each other. This has always been a grey area in 5839. I think a lot of older generations do not agree with running fire alarm and data together!
