Project Planning
The following is a typical program and timetable for a CF2000
installation project, once the initial order has been received:
1. Project Meeting
Installer and user to be present; system specifications, schematic
diagram and proposed circuit drawing to be available . CF2000
Installation & Commissioning Guide to be provided .
2. Equipment Fix
Typically 2 week's notice is required for equipment to be deliv-
ered . Cable to be installed and bases/back boxes to be fitted . Then
fire sensors, call points, alarm sounders and interface units can
installed .
3. Address Schedule
Schedule of sensor locations to be completed by installer and
returned to enable System programming .
4. Auto Learn
Fire panel/repeater panels to be installed and terminated . System
to be powered up by installer and auto learn mode activated (see
Auto Learn section) . System to be tested and verified by installer,
prior to final commissioning .
5. Final Commissioning
Minimum 2 weeks notice is required from receipt of Address
Schedule and Commission request form for an Eaton Fire Systems
Service Engineer to attend site to implement/oversee the final
commissioning procedures (see Commissioning section), in
conjunction with the installer .
System Design Guidelines
Guidelines
Systems should conform to the relevant local standards and codes
of practice . For the UK this is BS5839 part 1 . CF2000 meets all the
relevant requirements of BS5839 part 1: 2002 .
Installation planning is simplified by the fact that every address-
able CF2000 device contains an integral short circuit isolator . Care
must be taken to ensure that local standards requirements regard-
ing 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 commis-
sioning certificate (see Commissioning CF2000) .
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 espe-
cially 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 .
