5. Wiring
5.1 Power
Ensure 230Vac 10A dedicated live power circuit is available for the NAD cabinet.
5.2 Local Network
Generally the NAD uses the existing building structured cabling, therefore the
interconnection between NADs can be via UTP or Fibre depending what structured
cabling has been provided. Fire Panels and sprinkler Alarm systems each need to have
Fire resistant Cat5e/6 data cable run to the closest NAD. (see fig 1)
Normally an 8 way data outlet is required from either the building UTF distributor to the
NAD which is mounted nearby. If a fibre interconnection is used either between NADs, or
cabled to any building services equipment then a fibre outlet will be required at the NAD
from that building distributor.
5.3 Wide Area Network
Generally there will be either Voice Grade copper cable suitable for a xDSL service
available at the building distributor which where ALARMNZ will provision a connection to
the Telco Network. Occasionally there will be an FTTx Optical Network Terminal (ONT)
Layer 2 Ethernet handoff at the Telecom Demarcation and so in this case the wide area
network connection will be via a UTP cable to the building distributor . Additionally the
NAD normally includes a backup xG wireless connection that operates directly from the
NAD cabinet.
5.4 Labelling
The NAD will include outlet number labels consistent with the building UTF distributor
outlet numbering scheme.
5.5 Cable Specification
All services Network cabling is UTP Cat5e/6 except for the cables run from the Fire and
Sprinkler system to either the BD & FD cabinets which is Fire Resistant UTP Cat5e/6
(BS 6387 cwz ). Fire and Sprinkler Equipment patching NAD outlets within the IT room
can be standard UTP Cat5e/6. If services equipment is greater than 90 meters from the
NAD instead of UTP, a Fibre cable must installed and an additional Fibre outlet
between the BD or FD to the nearby NAD.
