The
following are the different types of fire alarm cables:
Plenum (FPLP)
Plenum
cables are used in ducts or other air spaces in buildings, either above drop
ceilings or under raised floors. They are fire resistant and produce minimal
smoke. To be fit for installation in the above-mentioned areas, fire alarm
cables must meet strict requirements of flammability and low smoke generation.
They are again classified into multi-conductor plenum cable and mid-
capacitance plenum cable.
Non-Plenum (FPL)
Non-plenum
cables are suitable for general purpose fire alarm use. They are not suitable
for installation in plenum, ducts or other spaces used for return air. However,
they are perfect for general purpose fire alarm applications, including surface
wiring for smoke alarms. Multi-conductor non-plenum cable, mid-capacitance
non-plenum cable and multi-paired non-plenum cable are three types of
non-plenum cable.
Riser (FPLR)
Riser
cables are designed for use in riser applications, meaning they can be used in
cable pathways that run vertically from floor to floor. They have
fire-resistant characteristics which help prevent fire from spreading to
multiple floors of a building. The multi-conductor riser cable is one type of
riser cable.
