Only approved cabling should be used in critical signal and control equipment in the event of a real fire, and the announcement of a revised version of the Code of Practice covering these areas of performance highlights how critical it is. Graham Turner of AEI Cables examines the detail.

The equipment served by these cables – including smoke and heat extraction systems – assists fire services in the case of firefighting and a safe evacuation in the case of life safety.

As the only supplier in the UK with independent approval from LPCB for BS8519 Category 3 Control fire performance cables with a fire survival time of up to 120 minutes, AEI Cables is highlighting the reference in the new revised version of the standard.

The standard clearly references and clarifies the products and levels of performance that should be used for all parts of the supply chain from specifiers to contractors and installers.

Anything inferior installed is dangerous and could lead to some of these systems simply not surviving in a fire with the dangers that brings. These cables reduce the risk to life through the reduction of harmful smoke, toxic gases, and reduced flame spread. We should all strive to achieve the highest performance possible.

Safe evacuation

There are many cases of cable failure where the products will simply not perform as specified and are not fit for the intended purpose. If in doubt, specifiers and installers should check with their supplier for advice.

Fire and rescue services depend on these systems to help to fight a fire and the safe evacuation of those who may be in the building – installing the wrong products can be catastrophic.

The applications of Category 3 Control fire performance cables also applies to evacuation alarms for the disabled in care homes, emergency voice communications systems and voice alarm systems in relevant buildings including tall buildings, office spaces, hospitals, care homes, shopping malls and stadia.

Meanwhile, the government has committed to progressing new legislation following the Grenfell disaster and outlined the concept of duty holders having clear responsibility throughout design, construction and occupation of buildings and enforcement. The proposed system will be underpinned by ‘strengthened enforcement and sanctions to deter non-compliance with the new regime.

The Fire Safety Bill, which was introduced to Parliament in April, will also empower fire and rescue services to take enforcement action and hold building owners to account if they do not comply with the law.

The BS Code of Practice under BS8519 contains six categories of cables, three for power cables and three for control cables each covering survival times of 30, 60 or 120 minutes.

Using the very latest in technology and science, the Firetec Total Fire Solutions range offers Mineral Insulated Cabling (MIC), Firetec Enhanced fire performance cabling, accessories and technical support from the AEI Cables distribution facility at Washington, Tyne and Wear.
