Seperation

[Overcurrent]

Contractor upgrading electrical installation, two compartment metal trunking, T&E in top portion and data, phone and door entry in bottom. The contractor also wants to put fire alarm cable in the trunking I said the 528-1 day should be separated they said no it’s fine. Who is right what reg could confirm contractor stance.

What does that mean?

k) To avoid the risk of mechanical damage to fire alarm cables, they should not
be installed within the same conduit as the cables of other services. Where
fire alarm cables share common trunking, a compartment of the trunking,
separated from other compartments by a strong, rigid and continuous
partition, should be reserved solely for fire alarm cables.

and

l) To avoid electromagnetic interference with fire alarm signals, any
recommendations by the manufacturer of the fire alarm equipment in
respect of separation of fire alarm cables from the cables of other services
should be followed.

and

n) Fire alarm cables carrying power in excess of ELV should be segregated from
ELV fire alarm circuits by use of cables conforming to 26.2b) and with 26.2l). In
particular, the mains supply cable to any control, indicating or power supply
equipment should not enter the equipment through the same cable entry as
cables carrying ELV. Within the equipment, low voltage (LV) and ELV cables
should be kept separate to the extent practicable.
