Musical Door Chime
MODEL LB-55
MODEL LB-60 PROGRAMMABLE CHIME
This musical door chime may be connected to a NuTone
Radio-Intercom System to provide the intercom speakers
with the chime tones. If it is acceptable to have the chime
tones
override
the radio and intercom (chime heard as well
as radio and intercom,) connect chime to intercom as shown
on the primary instruction sheet for the chime. If you wish the
radio and intercom to be
muted
(silenced) when the chime
is playing, the connections between the chime and intercom
must be as shown here. If you wish the
door speakers,
as
well as the inside/patio speakers to receive the chime, see
pages 2 and 3 for wiring information.
*SPECIAL NOTE: In IMA-806 systems connected for
MUTING as shown in this page and page 4, it should be
considered that music will remain muted after a chime
tune completion – until either an “END CALL” switch is
pressed or the automatic end call timer resets the IM-806
control circuit.
