FP PLUS

What is FP PLUS?

FP PLUS is an “Enhanced” fire resistant cable specially designed to meet the requirements of BS 7629-1 for fire alarm, emergency lighting, life safety and fire-fighting systems in buildings. Prysmian invented the first extruded polymer fire resistant cables and FP PLUS is the results of expertise and experience of our scientists and engineers. FP PLUS is assessed and certified by independent and accredited bodies, LPCB and BASEC

Why do I need FP PLUS?

Fire risk assessments must be carried out by law which means fire alarms, emergency lighting, life safety and fire-fighting systems are usually needed for hospitals and large, complex buildings.

FP PLUS is an “Enhanced” fire resistant cable and the ideal choice for these buildings. Buildings such as offices and shops typically require a “Standard” fire resistant cable, Prysmian FP200 Gold. FP PLUS is a dressable, aluminium screened cable, with a hard, damage resistant enhanced INSUDITE® insulated system.

It also features an un-insulated tinned copper Circuit Protective Conductor (CPC). FP PLUS always gives a quick and dependable installation and termination for your project providing confidence and reliability during commissioning and handover.

What Does ‘Enhanced’ Mean?

Prysmian FP PLUS is an ‘Enhanced’ cable fire-resistant cable, which means it can continue to work for over 120 minutes in the event of fire. FP PLUS is tested to both BS EN 50200 and BS 8434-2, these classification goes beyond ‘standard’ fire resistance by requiring the cable to pass additional tests, including exposure to mechanical shock and water spray, simulating real-world emergency scenarios. Enhanced fire performance cables are essential in life safety systems such as fire alarms and emergency lighting, where continued operation during a fire can be critical. Prysmian FP PLUS meets these higher standards, offering peace of mind for specifiers working on complex or high-risk environments.

Dressability

FP PLUS uses the original FP concept of a pliable aluminium tube construction. This allows installers to 'dress’ cable to the desired cable route without ‘spring-back’ or ‘memory’. It also allows straightening and reverse bending, which is particularly important in enclosed voids or cabinets, where final cable routes may change.

Less mess

Its compact, innovative construction eliminates the need for any additional chalk or powders inside the cable to help sheath removal and it has no additional glass-fibre tapes, reducing waste and mess.

Easy termination

With the outer sheath bonded to the inner aluminium screen along its entire length, sheath removal is easy and reliable. With a light, shallow cut and a quick snap, the sheath is easily removed and comes away readily in a single piece, quickly exposing the cores.

Why is FP cable fixing critical?

Circuit integrity is the critical task required by fire resistant cables which means the cable MUST keep working by transmitting voltage and current safely to keep the system working. Therefore, all FP cables should be fixed securely to the building structure using non-combustible, permanent cable fixings that will not melt, burn, or perish causing the collapse of cables in a fire. Copper or ferrous fixings are suitable but aluminium, melting point 660˚C, is not.

 

As well as being non burning – any fixing selected should not impede the cable performance during a fire to guarantee that the cable will carry on working. Choose BICON® cable accessories by Prysmian which have been fire tested with associated Prysmian FP cables.

AP clips

This traditional solution ensures a positive, whole cable and secure fixing that stops collapse and keeps circuit integrity when a building is on fire.
