10 Installation for the Street Lighting Solution
Overview
The process for installing a street lighting network includes the following basic
tasks:
• Install a Segment Controller
• Install luminaires
• Install CRD 3000 Street Light Bridge modules, as needed
For a typical new installation, you install the Segment Controller first. However,
you could install luminaires (or have already existing luminaires), and then
install the Segment Controller. In either case, you install CRD 3000 Street Light
Bridge modules, as needed, to enable and extend the network. A single Segment
Controller can support up to 200 devices, including both luminaires and CRD
3000 Street Light Bridge modules.
For an existing installation, typically the luminaires and the Segment Controller
are already installed. In this case, you can add additional luminaires to define
additional network segments, or you can install CRD 3000 Street Light Bridge
modules to enable and extend the communications range for the network.
To decide when to install a CRD 3000 Street Light Bridge module, you generally
install luminaires and add them to the Segment Controller (or allow the Segment
Controller to automatically discover and commission the luminaires), then verify
that they were all commissioned. If any of them could not be commissioned,
install a CRD 3000 Street Light Bridge module near one of the commissioned
luminaires (to be sure that the Segment Controller can communicate with the
newly installed CRD 3000 Street Light Bridge module). Then, you install a
companion CRD 3000 Street Light Bridge module at the luminaire that could not
be commissioned so that the Segment Controller can discover and commission it.
If there are additional uncommissioned luminaires after the installation of the
first pair of CRD 3000 Street Light Bridge modules, you can add additional CRD
3000 Street Light Bridge modules, for example, at the end of the first
uncommissioned street light chain and the start of the next chain.
You can repeat these three steps many times to install a complete street lighting
solution. Typically, you install hundreds or thousands of luminaires, a small
number of Segment Controllers, and dozens or hundreds of CRD 3000 Street
Light Bridge modules. How many CRD 3000 Street Light Bridge modules are
required depends on the number of luminaires each service distribution
transformer supports, and on the kind of network topology that is required for
the street lighting solution.
