Overview
Using the RadioRA
®
Telephone Interface
Wiring
The RadioRA® System can now be controlled from any location worldwide by using the RadioRA Telephone Interface (RA-
RC-3). The Telephone Interface allows for activation of scenes programmed to a RadioRA Switch Closure Interface (RA-SCI)
via telephone. By connecting the three (expandable to nine) outputs from the Telephone Interface to the inputs of the RA-
SCI, pressing buttons on any telephone will turn lighting scenes ON/OFF.
The wiring diagram below shows how to wire up three outputs from the RadioRA Telephone Interface (RA-RC-3) to the
inputs of a RadioRA Switch Closure Interface (RA-SCI). The RA-RC-3 and RA-SCI can then be programmed as described
on the following page to activate the desired scenes. For this application, RA-SCI inputs must be set up for MOMENTARY
operation. A dedicated phone line is not required, but is recommended.
* The RA-RC-3 monitors for DTMF tones anytime the phone line is in an off-hook condition. This allows for its use in conjunction with an
answering machine.
After wiring as above, proceed to programming on the following page. To have additional information faxed to you concerning
the Telephone Interface, call 715-386-4345 and request document #165.
