In airport environments,
where higher than normal levels of electro magnetic
radiation are present, alarm systems could be
vulnerable to false alarms. Firetuf emc cables
were specifically designed to meet the onerous
requirements for immunity to Electro Magnetic
Interference (EMI) and have been supplied for
London Heathrow Terminal 5. Zero Halogen, Low
Smoke (OHLS®) cable, maintaining circuit
integrity when exposed to fire, meeting the
Standard category of BS 5839-1:2002. Manufactured
to BS 7629-1. Tested and approved by LPCB and
BASEC.
These cables are suitable
for installations where a fire situation may
pose a major hazard and the maintenance of circuit
integrity is a requirement, thereby giving increased
protection to life and property. Application
of the latest sheath extrusion technology and
100% cover electrostatic screen, gives Firetuf
emc its unique advantages which include:
• Increased immunity
to EMI
• Available in long length
• Ease of handling and installation
• Lower termination costs
• Twisted core construction to improve
signal clarity
• Suitable for use in Zone 1 and Zone 2

Clip & Gland Selection
Chart
Clip and nylon
gland references are for white, if red is required
add the letter “R” after the clip
or gland coding.
* Clips for 2 or 3 cables.
** For ’Enhanced’ performance with
Firetuf Plus, A2 brass glands should be used
for through joints.
** For Hazardous Areas, flameproof A2F brass
glands should be used.

All Firetuf cables are
tested and Certified by LPCB and BASEC
to the latest edition of appropriate Standards. |

Appropriately jointed
Firetuf cables continue to provide circuit
integrity up to the full BS 5839 rating.
BS 5839-1:2002 recommends
that cables are installed without joints
if possible. When through joints are used,
all terminations and other accessories
should be such as to minimise the probability
of early failure in the event of a fire. |
Current Rating and
Associated Volt Drop
BS 7629 limits maximum
conductor temperature (unless enclosed) to 70ºC
* As defined in Appendix 4 of BS 7671, the IEE
Wiring Regulations, 16th Edition.
Conductor operating temperature: 70ºC. Ambient
temperature: 30ºC
