All cables should be screened.
Minimum detection loop conductor section size is 0.5 sq.mm
Maximum detection loop conductor section size is 2.5 sq.mm
There should only be one analogue detector loop per shielded cable.
Analogue detector loops and conventional sounders should not run in the same shielded cable.
If the system requires one or more repeaters, it will be necessary to use a four core data cable to create a
data loop between the panel and the repeater. Alternatively, it is possible to use multi-mode dual-core
fibre-optic cable or a TCP/IP connection for the same purpose.
Data loop cable should be RS422/485 grade data cable, eg:
Signal cables for RS485 Communication Links (twisted pair) to Repeater panels

Limitations
A fire alarm system can provide early warning of a developing fire but it does not assure protection
against damage or loss resulting from a fire.
The fire alarm system should be designed and installed in accordance with all relevant regulations
and codes of practice.
To ensure maximum protection the system should be regularly tested and inspected by qualified fire
alarm installation personnel. Inspection and testing should be carried out in accordance with the
appropriate local standards.
