Where it is a requirement that the patch leads are protected by conduit it may prove more
convenient to run the cables unterminated and attach the RJ45 connectors afterwards. In this case
the cable used should be 4-twisted pair, 24awg multistranded, unscreened data cable to Category
5E standard, (e.g. Belden Datatwist 350). No strain-relief hoods should be fitted to the insulation
displacement RJ45 connectors, due to the limited space available above the emplaced detector.
The wiring scheme used should follow either the T-568A or the T-568B Ethernet standards, and
must give "1-1", "straight-through" connectivity between the two RJ45 connectors for all eight
cores.
Note that this detector is not an Ethernet device and cannot be used with network
Hubs and Switches.
Plug the RJ45 connector at the detector station into the modular socket labelled "To CD Box" on the
top of the detector module and offer the detector to the flush ring or backbox so that the arrow
symbol on the detector label points in the same direction as the arrow symbol inside the backbox.
When the multi-tab bayonet fitting is engaged, twist the detector clockwise to retain it and tighten
the locking screw until the head is flush to secure it.

Commissioning
In the CDW12U5 and CDH4U5/CDH8U5 systems, all configuration information is held within the
LCMs themselves, not in individual detectors. Most of the configuration items are set up with the aid
of a dedicated programme running on a portable PC which communicates with the LCM either by an
infrared link, via one of the attached detectors, or by a specialised serial link into the LCM itself.
However, when setting the actual light levels around which
switching decisions are to be
made, the system allows the commissioning engineer the same convenience as if he were dealing
with traditional stand-alone detectors. An infrared programming tool, the HP2000 or HC5, is used to
set the
switching setpoint for the photocell. In all cases the setting is then transmitted
from the detector to the LCM, where it is uniquely associated with the detector number being dealt
with and will be preserved in the event of power failure. All settings can be re-programmed any
number of times.
Setting the Regulating Photocell
Using the HP2000 Programmer, enter the Utilities menu and select ‘Set Light Level’. Use the ‘up’
and ‘down’ buttons to manually adjust the light output from the luminaire(s) and when at the required
