Can fire alarm cables (extra low voltage) and PA system cables (low voltage) be run on the same traywork without seperation?

BS 5839 pt 1 26.2 l

"To avoid electromagnetic interference wth fire alarm signals, any recommendation by the manufacturer of the fire alarm equipment in respect of the seperation of fire alarm cables from the cables of other services shold be followed".

Ask the manufacturer of the cable!
