OPTIONAL FEAT U R E S
USING THE MUSICAL CHIME WITH A NUTO N E
RADIO-INTERCOM SYSTEM
If desired, the Musical Chime may be used with a NuTo n e
Radio-Intercom System. The chime signal will override
the radio-intercom but will not mute the music source.
Refer to the wiring diagram below that corresponds with
the radio-intercom system being used. Connect the wires
(use NuTone IW-2) to the Musical Chime's circuit board
terminals located inside the chime's housing.
To adjust the chime's volume so that it will be heard over
the radio-intercom, use a screwdriver to turn the recessed
control located below the I-COM terminals on the circuit
b o a r d .
USING THE MUSICAL CHIME WITH
AN EXTERNAL SPEAKER
If you do not have a NuTone Radio-Intercom System
but would like for the Musical Chime to be heard in another
section of the home, one external speaker may be used with
the Musical Chime. Note: Speaker must be purchased
separately from NuTo n e .
Use a surface-mounted speaker if the Musical Chime
needs to be heard in another room of the home.
Or, if the Musical Chime needs to be heard at the front
door, use a speaker that includes a pushbutton at that
location. NOTE: If a speaker that incudes a pushbutton
is used, the diode must be added to the pushbutton.
Connect speaker terminals to the Musical Chime's circuit
board at SPKR+ and SPKR– inside the chime's housing.
Polarity need not be considered; connect either of the
speaker's terminals to either SPKR terminal on the Musical
C h i m e .
