18 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 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 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 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 Street Light Bridge modules to
enable and extend the communications range for the network.
To decide when to install a 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 Street Light Bridge module near one of the commissioned luminaires (to
be sure that the Segment Controller can communicate with the newly installed
Street Light Bridge module). Then, you install a companion 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 Street Light Bridge modules, you can add additional 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 Street Light Bridge
modules. How many 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.
