FAQs on FP

FP Cables Recently Asked Questions

Q. What does ‘standard’ and ‘enhanced’ mean?
A. Standard  fire resistant cables (FP200 Gold) pass the 30 minute  fire, water and shock test at 850°C, enhanced cables (FP PLUS) pass the two hour fi re test at 930°C. BS’s for fire alarm and emergency lighting require both types and our ‘FP GUIDE Series’ will help you decide which to use.
 
Q. Silicone cables don’t pass the fire test on one sample though do they?
A. FP does. The fire test needed to pass the fire alarm standard and the emergency lighting standard are both flame, water and impact on the same 1200mm sample of cable for both FP200 Gold and FP Plus.
 
Q. Can I use red LSOH nylon cable ties FP?
A. Not as the only means of support. Fire detection, fire communication and fire fighting and life safety circuits each have a BS to describe cable installation and they all state fire resistant cables must be fixed with metal so as to not compromise cable performance; that means iron, steel or copper.
 
Q. Do I have to use brass glands on FP200 Gold or FP PLUS smoke or fire detector circuits?
A. No. The glands protect the devices or enclosures from the ingress of moisture and airborne particles at the cable entry point. They are not part of the fire resistance but they should be low smoke and zero halogen like the nylon FP gland.
 
Q. The emergency lighting standard only calls for the PH60 fire and shock test.
A. It’s changed. BS 5266-1:2005 has been replaced by BS5266-1:2011 which now calls for standard and enhanced cables just like the fire alarm standard.
 
Q. I heard FP200 needs ferrules: where can I get them?
A. It doesn’t. FP200 Gold replaced FP200 in 1995 with Insudite™ damage resistant insulation: ferrules are redundant. Everyone prefers insudite because it withstands significantly more force than the ordinary silicone used by others that means less time and money wasted by you for someone else’s mistakes.
 
Q. Can I joint FP cables?
A. Avoid. All of the British Standard Codes of Practice for fire cables refer to joints and recommend they should be avoided where practicable. If a joint is absolutely necessary then it must use ceramic terminals a sealed fire resistant box.
 
Q. Is 6491B in steel conduit suitable for fi re detector circuits?
A. No, use FP100. 6491B is not  fire resistant, in the event of fire it will burn and cease to function in screwed steel conduit. Fire alarms and emergency lighting circuits must be wired with  fire resistant cable or cable system. FP100 meets that requirement in screwed steel conduit.
 
Q. FP cables work at over 800°C, can I use them in a 200°C industrial installation?
A. No. FP cables are fire resistant, that application needs a high temperature cable.
