Installation
The installation shall be in accordance with the regulations either of
the approval body for an approved system, or otherwise, to the
national code of practice/regulations for the installation of the fire
alarm system, e.g. BS 5839 part 1.
Electromagnetic Compatibility (EMC)
On a site where there is an unusually high level of potential electrical
interference, e.g. where heavy currents are being switched or where
high levels of R.F. are prevalent, care then must be taken in the type
and routing of cables. Particular care should be given to the
separation of zone wiring from the cable carrying the interference.
