Section 1: System installation and design
5. Final commissioning
Minimum 2 weeks notice is required from receipt of Address Schedule and
Commission request form. Eaton Lighting Service Engineer to attend site implement/
oversee the final commissioning procedures (see Commissioning section), in
conjunction with the installer.
System design guidelines
Guidelines
Systems should 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: 2002. 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 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.
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 (e.g. interfaces, loop repeaters etc.) When designing
systems its recommended that allowances are made for future expansion, Short
circuit isolators are incorporated into every 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.
Loop connected repeater panels
Each repeater unit requires one address and consumes no more current from the
loop than a smoke sensors. The repeater also requires a local mains supply and
incorporates battery backup.
Loop loading system verification
Loop load calculations should be carried out prior toinstillation.
