Fire-resistant is not the same as flame-retardant

The single most expensive misunderstanding in UAE cable procurement is treating these two properties as interchangeable. They are tested differently and they do different jobs:

  • Flame-retardant (IEC 60332) means the cable resists propagating flame along its own length. It does not promise the circuit still works. Ordinary building cable is usually flame-retardant.
  • Fire-resistant / fire-rated (BS 6387, IEC 60331) means the conductors keep carrying their signal or power while burning, for a defined period. This is what keeps a fire alarm sounding, a smoke fan turning and a firefighting lift moving during an evacuation.

Only the second category satisfies a life safety circuit. A submission that offers a flame-retardant cable where the code calls for circuit integrity is rejected, and correcting it after the containment is installed is a rip-out, not a substitution.

Reading the BS 6387 code correctly

BS 6387 expresses performance as a string of letters, and each letter is a separate test. You need one from each of the three groups:

  • Fire alone — A: 650°C for 3 hours; B: 750°C for 3 hours; C: 950°C for 3 hours; S: 950°C for 20 minutes.
  • Fire with water — W: 650°C for 15 minutes, then water spray applied while heating continues for a further 15 minutes. This simulates sprinkler or hose discharge onto a hot cable.
  • Fire with mechanical shock — X: 650°C; Y: 750°C; Z: 950°C, each with the cable struck at intervals to simulate falling debris and structural movement.

So the widely specified Cat CWZ means 950°C for 3 hours under fire, plus survival of the water test, plus survival of the shock test at 950°C. Specifying only "BS 6387" without the letters is meaningless — it permits a Cat AX cable that fails at a third of the temperature. Write the full designation into the specification and the material submittal.

Standard versus enhanced, and the FP200 question

BS 5839-1 divides fire alarm cabling into standard and enhanced. Enhanced cable is required where the alarm must survive far longer than a simple evacuation — phased evacuation buildings, tall buildings, premises with a fire strategy that depends on the system running while the fire develops. Enhanced performance is demonstrated by BS 8434-2: 930°C for 120 minutes with both mechanical shock and water applied. In European classification terms this maps onto the PH120 rating from EN 50200, where PH30, PH60 and PH120 simply state the survival time in minutes.

"FP200" is a Prysmian product name, not a standard — but it has become the generic shorthand in UAE specifications, which is why local datasheets are written as "FP200 equivalent". When you receive that phrase, do not accept it at face value: ask which BS 6387 categories the cable actually holds and whether it is BS 8434-2 tested. A cable can be dimensionally similar to FP200 and still fall short on the shock or water test.

Where the UAE code requires it

Circuit integrity is required wherever a system must keep operating after the fire has started. On a typical Abu Dhabi or Dubai project that means:

  • Fire detection and alarm loops, sounder circuits and interfaces to the fire panel.
  • Emergency and escape lighting circuits that are not self-contained.
  • Fire pump feeders, and the supply to jockey and standby pump sets.
  • Smoke control and stair pressurization fan supplies, together with damper control wiring.
  • Firefighting lift supplies and their control wiring.
  • Voice alarm and firefighter telephone systems, and public address used for evacuation.
  • Generator and essential-services distribution feeding any of the above.

The survival rating must be at least the operational period the fire strategy claims for that equipment. A 120-minute smoke extract duty fed by a 30-minute cable is an internally inconsistent design, and reviewers do check this against the cause-and-effect matrix.

The mistake that fails more inspections than the cable itself

A fire-rated cable is only as good as what holds it up. Under fire, plastic cable ties and PVC trunking soften within minutes; the cable then falls, is severed or is pulled apart at its terminations, and the circuit is lost even though the cable itself was still intact. Authorities and third-party inspectors specifically look for:

  • Metal fixings throughout — steel cable ties, metal clips, metal saddles. Plastic ties are not acceptable on fire-rated routes, including as temporary supports left in place.
  • Metallic containment and supports, with support spacing per the manufacturer instruction rather than general practice.
  • Fire-rated glands, boxes and accessories — the termination must match the cable rating; a standard junction box defeats it.
  • Correct firestopping at every penetration, using a system tested with that cable and that barrier construction. Firestopping is a separate certified system, not sealant of convenience.

Also confirm the cable is LSZH where the code requires it: IEC 61034 limits smoke density and IEC 60754 limits acid gas, both of which matter in enclosed escape routes and in equipment rooms where corrosive gas would destroy electronics the fire never reached.

Buying in the UAE: what to verify before you order

The UAE is well supplied for fire-rated cable, with local manufacture as well as imported European brands. Ducab manufactures in the UAE and its Flambicc range is the local reference for fire-resistant building wiring; Draka and Nexans are the common imported alternatives, and regional brands cover the mainstream sizes. Whichever route you take, the approval depends on paperwork as much as on the cable:

  • Third-party certification — LPCB, BASEC or equivalent. A manufacturer self-declaration is not third-party certification, and Civil Defence review distinguishes between them.
  • A test certificate that names the exact construction you are buying: conductor size, number of cores, voltage rating and the full BS 6387 designation. Certificates are frequently supplied for a sister product in the same family.
  • Voltage rating fit for purpose — 300/500 V is normal for detection and alarm, while power circuits to pumps and fans need 600/1000 V. Mixing them up is a common submittal rejection.
  • Batch traceability — drum markings and delivery notes that tie back to the certificate, because inspectors sample this on site.
  • Sufficient lead time. Enhanced BS 8434-2 cable in larger sizes is not always ex-stock in the region; confirm availability before the programme depends on it.

Frequently Asked Questions

What is the difference between fire-rated and fire-resistant cable?

In UAE practice the terms are used interchangeably and both mean a cable that continues to carry its circuit during a fire, tested to BS 6387 or IEC 60331. The genuinely different term is flame-retardant (IEC 60332), which only limits flame spread along the cable and gives no guarantee the circuit survives. Life safety circuits need fire-rated cable, not merely flame-retardant cable.

What does BS 6387 Cat CWZ mean?

Three separate test results in one designation: C is survival in fire at 950°C for three hours, W is survival of a water spray applied during the fire test, and Z is survival of mechanical shock while held at 950°C. CWZ is therefore the highest common combination and is what most UAE fire alarm and life safety specifications call for.

Is FP200 approved in the UAE?

FP200 is a brand name rather than a standard, and it is widely used and accepted. Local specifications usually say "FP200 equivalent", which means the cable must match its performance — so the question to ask a supplier is which BS 6387 categories the product actually holds, and whether it is tested to BS 8434-2 where enhanced performance is required. Approval follows the test certificate, not the brand.

When do I need enhanced (BS 8434-2) cable instead of standard?

Enhanced cable is required where the fire strategy depends on the system operating well beyond a simple single-stage evacuation — typically phased evacuation, tall buildings, and any case where the alarm, voice alarm or smoke control must keep running while the fire develops. The rule of thumb is that the cable survival time must be at least the operational time the fire strategy claims for the equipment it feeds.

Can I use plastic cable ties on fire-rated cable?

No. Plastic ties and plastic containment soften and fail within minutes in a fire, dropping the cable and breaking the circuit even when the cable itself is undamaged. Fire-rated routes require metal fixings, metallic containment and fire-rated glands and accessories throughout — this is one of the most frequently raised inspection findings on otherwise correct installations.

Who supplies fire-rated cable in the UAE?

Both locally manufactured and imported products are readily available — Ducab manufactures fire-resistant cable in the UAE under the Flambicc name, while Draka and Nexans are common imported options alongside regional brands. What determines acceptance is not the origin but the documentation: valid third-party certification such as LPCB or BASEC, a test certificate matching the exact size and construction ordered, and traceability from the drum to that certificate.
