6.7.1 Door Side Module Electrical Connections and DIP Switch Settings
The Door Side (NIDM) Module is an “active peripheral” therefore it must be connected to one of the four
room buses of a teleCARE IP room controller by the 4-pole room bus connector (see 6.4.1, 4-Pole
Connector Terminal on page 60).
Each room bus offers individual addresses for up to four switch modules. The address is selected using
the DIP switch on the switch module printed circuit board. The door side module also has another 4-pole
connector for a “passive bus” which is used to connect a passive pull cord switch module and a passive
cancel switch module.
Note: Only one passive pull cord switch module can be connected per passive bus.
