System design guidelines
5. Final commissioning
A minimum of two weeks notice is required from receipt of Address Schedule
and Commissioning request form for a Eaton Service Engineer to attend site and
implement/oversee the final commissioning procedures (see Commissioning
section), in conjunction with the installer .
System design guidelines
Guidelines
Systems should be installed to the relevant local standards and codes of practice,
for the UK this is BS5839 part 1 . The panel meets all the relevant requirements
of BS5839 part 1: 2017 . Installation planning is simplified by the fact that every
addressable 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 section)
Loop lengths
The maximum permitted loop length is 2 km measured from the near to the far
terminals on the panel 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 .

See loop loading system verification section below .
Loop loading - total number of addresses
The total number of addresses per loop is 200 . this includes sensors, call points
and all other addressable items . When designing systems its recommended that
allowances are made for future expansion, Short circuit isolators are incorporated
into every panel loop device, including Smoke sensors, heat sensors, 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 .
Repeater Panels
Each repeater unit requires one address and consumes no more current from the
loop than a smoke sensor . The repeater also requires a local mains supply and
incorporates battery backup .
