Recommended Cables
All cables connected to the fire alarm control panel must be fire resistant cables. Shielded cable must be used for
signalling loops and sounder circuits. The drain earth wire should be connected to a suitable earth bonding point at
both ends of the cable. Keep the earth connections as short as possible.
In the UK, the British Standard BS5839 Part 1 : 2002 Code of Practice for system design, installation, commissioning
and maintenance states the requirements for standard and fire resisting cables in Clause 26.2 section d and e:
‘
d) Standard fire resisting cables
should meet PH30 classification when tested in accordance with EN50200 and
maintain circuit integrity if exposed to the following test:
- A sample of the cable is simultaneously exposed to flame at a temperature of 830°C – 0+40°C and mechanical shock
for 15 minutes, followed by simultaneous exposure to water spray and mechanical shock for a further 15 minutes.
e) Enhanced fire resisting cables
should meet the PH120 classification when tested in accordance with EN50200
and maintain circuit integrity if exposed to the following test:
- A sample of the cable is simultaneously exposed to flame at a temperature of 930°C – 0+40°C and mechanical shock
for 60 minutes, followed by simultaneous exposure to water spray and mechanical shock for a further 60 minutes.’
Loop cable
A loop cable carries data therefore its selection is important. Note the following:
- In countries where the European EMC directive is in force, only EMC Compliant cables are to be used.
- The loop cable usage must not exceed 1.5 km. This includes the cable used on main loop and spur circuits.
- Single pair cables must be used. It is NOT permissible to run mixed loops or outgoing and return pairs in a multi-
core cable due to inadequate separation and possible electrical interference problems.
- Each core of the loop cable must be a minimum 1.5mm2 cross sectional area.
- The cable screen must be capable of being earthed at each system device – only one end of each cable screen
must be earthed.
- Red is the preferred cover sheath for fire applications
- The specified loop circuit cables are also suitable for wiring alarm, auxiliary relay and input/output lines.
Mains supply cable
The mains supply cable must be a standard fire resisting type and should meet PH30 classification, such as any of
the standard and enhanced cables listed below. Examples of enhanced and standard cables are:
Enhanced:
- Mineral insulated cable (MICC) to BS6207: Part 1
- Draka FIRETUF Plus Enhanced FTPLUS2EHL5RD
Standard:
-
Prysmian FP200 FLEX
-
Prysmian FP200 GOLD
Refer to your supplier for details of other available industry standard fire resisting cables.
