MULTI-TONE CHIME

device. This kit is primarily intended for use as a replacement for
the traditional mechanical doorbell. Of course, it can also be used
for many other types of application. The number of tones may be
selected up to a maximum of three, each of which is output one
after the other. This can be used to help locate the place being
called. Volume and tone can also be set according to help locate
the place being called. Volume and tone can also be set according
to choice and the existing bell transformer can be used as a supply.
