FP300 LPCB Ref No: 077e/01

FP300 > Prysmian FP300 is designed for cabling essential safety circuits
associated with life safety, fire fighting or property protection
applications used in a wide range of public access and industrial
complexes where continued circuit operation in the event of fire is
required. These include critical circuits associated with fire detection
and fire alarm systems, emergency lighting systems, smoke control,
fire supression systems, evacuation lifts, sprinkler and riser pumps.
> Prysmian FP300 is an unarmoured cable with inherent fire resistance
providing an easy to install and terminate fire resistant wiring
system. In addition to maintaining circuit integrity during a fire,
FP300 produces very low levels of smoke and virtually no (less than
0.5%) acidic gases, thus safeguarding human life and protecting
equipment.
> FP300 handles like a standard unarmoured cable and can be
installed just as easily. No special tools or accessories are needed
for installation or termination of FP300.
> FP300 is suitable for indoor or outdoor installation. For external
exposure the use of a black sheath is recommended.

APPROVALS > Prysmian FP300 is Loss Prevention Certification Board (LPCB) listed
as a fire resistant cable and is approved to BS6387 Category CWZ
at an enhanced voltage of 600/1000V and IEC 331 at an enhanced
temperature of 950C.
> All Prysmian FP300 cables are manufactured under an ISO 9001
Quality System certified by BASEC and LPCB.

INSTALLATION > Prysmian FP300 is particularly suitable for tray, ladder, trunking and
clipped direct applications. It should be installed in accordance with
BS7671/IEE Wiring Regulations or any other appropriate national
regulations. Although standard cable fixings and glands, nylon or
brass, may be used, it is important to ensure that, when the cable
system is required to maintain circuit integrity in a fire, any fixing
used to support the cable can also withstand that fire.
> Minimum recommended installation temperature 0C.

Note 1. The majority of cores in a multicore auxiliary cable carry only small or intermittent current and a current rating based on
the assumption that only 2 cores, the positive and negative (or line and neutral) feed cores approach the maximum
permitted current loading is given. Where all cores in a cable are equally loaded the following factors should be
applied to the 2 core rating.

Number of cores 2 7 12 19 27 37
Rating factor 1.00 0.63 0.53 0.45 0.40 0.36

Note 2. The short circuit rating is limited by the bursting strength of the unarmoured cable design.
