System Installation and Design
System Design Guidelines
Guidelines
Fire detection and fire alarm systems for buildings should conform to the
relevant local standards and codes of practise . For the UK, these are BS 5839-1
(non-domestic premises) and BS 5839-6 (domestic premises) . Both BS 5839-1 and
BS 5839-6 require the Control and Indication Equipment (CIE) to conform to
BS EN 54-2 . The CF2000 fire control panel has been certified to BS EN 54-2 .
Therefore, the panel is suitable to be installed in applications which have been
designed in accordance with the relevant BS 5839 codes of practise .
Installation planning is simplified by the fact that every addressable CF2000 device
contains an integral short circuit isolator . Care must be taken to ensure that local
standards requirements regarding aspects such as loop coverage, area covered by a
single spur and cable specification are observed .
There may be certain applications in which deviations from the code may be
necessary and these must be listed on the commissioning certificate (see
Commissioning the panel) .
Loop lengths
The maximum permitted loop length is 2 km measured from the near to the far
terminals on the CF2000 Motherboard PCB . There is no minimum limit to loop
length . Any wiring spurs off the loop must be included within the 2 km limit . On long
loop runs, the lengths of wiring rises and falls (between floors, down to manual call
points) must be included . Remember to include these especially when taking loop
lengths from plan drawings .
Loop loading - total number of addresses
The total number of addresses per loop is 200 (99 Belgium) . This includes detectors,
call points and all other addressable items and call points . When designing systems
its recommended that allowances are made for future expansion, Short circuit
isolators are incorporated into every CF2000 loop device, including Smoke detectors,
heat detectors, sounders, callpoints and interfaces . Therefore, no further fault
protection is required . In the event of a single fault, none of the devices connected
to the loop will fail to operate as the fault will be isolated by the
two adjacent devices .
Spur connected devices downstream of a cable fault will cease to function .
