RECOMMENDED CABLE:
Cable should be BS approved FPL, FPLR, FPLP or equivalent.
While SMART Connect Multi-loop conventional Zone modules can
support cable runs greater than 2000m, it is generally better to plan
the system to use more manageable lengths.
NOTE:
It is not recommended to mix
different detector manufacturers on
a zone.
NOTE:
It is recommended that all
manual call points are connected at
the start of the zone.
