Application Note
Joining multiple Room Controllers via the keypad interface
Overview
The Room Controller Wallstation interface provides +24 VDC power for up to twelve wall mounted switch
stations. Each wallstation can support multiple pre-configured control functions. These include zone (load)
toggles, or preset scene trigger commands. This also allows multiple wallstations to use the same interface
port on a Room Controller. Wallstations can also share the same control function in different locations
creating a multi-way control scenario.

Control Sequence: Wallstations can be shared
between up to four Room Controllers. Button
presses will perform the same function in all
connected Room Controllers.
Uniquely connected occupancy sensors and
daylight sensors will control the Room Controller
they are connected to only. This can allow for
wallstations to be shared over a large area and
occupancy and daylight sensors to control
smaller zones.

Lighting control scenarios can take further advantage of this method by connecting one or more
wallstations to up to four Room Controllers. The wallstation is equipped with two RJ45 connectors to
allow the signals to pass through to another wallstation. Each connector on a wallstation can then be
connected to a different wallstation or Room Controller for simultaneous control of both panels via any of
the wallstations. This is depicted in Figure 1 below.

port on the Room Controller and to one
of the Click & Go ports on the Entry
wallstation. Connect up to twelve
wallstations using additional
QuickConnect cables to connect station
to station.

Technical Details
The +24 VDC power for the wallstation will be supplied by at least one of the Room Controller wallstation ports. Each port
has a series diode for over-voltage protection of the power output, which allows two ports to be connected on the same
Cat5e cable without damage. However, one or both ports may supply power to the wallstations depending on the voltage
drops of the two diodes.
Up to twelve Room Controller Wallstations may be shared with up to four Room Controllers to provide large area control with
shared multi-way wallstation configurations.
The +24 VDC external power limit, which is approximately 90mA across all of the external ports, allows for multiple device
connections. The application note Room Controller accessory power allocation details the DC current usage of each Room
Controller accessory. Any combination of accessories may be connected to the sensor, keypad and slider RJ45 jacks as long
as the maximum current limit is not exceeded.
NNote: The Quiet Time LED on every Quiet Time button on any of the keypads, if equipped, will be illuminated when Quiet
Time Mode is entered on any of the keypads.
