NuTone LA-52 Series Optional Features, Using the Musical Chime with AN External Speaker

OPTIONAL FEATURES

USING THE MUSICAL CHIME WITH A NUTONE RADIO-INTERCOM SYSTEM

If desired, the Musical Chime may be used with a NuTone 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 board .

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 NuTone .

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 Chime .
