Section 7 - ENVIRONMENTAL
PARAMETERS
Temperature Considerations:
Over the range from -10 ºC to +55 ºC
Humidity:
Relative Humidity of up to 95%, measured at 50 ºC,
non condensing.
Section 8 - EMC
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.
