WARNING: Turn power off at fuse or
circuit breaker before installing
transformer. Follow all national and
local codes.
1. Mount Transformer: Transformers

should be mounted on or near a
junction box. They can also be
mounted to the electrical service
panels. Junction boxes in utility
rooms, crawl spaces, or basements
are preferred. Avoid attic locations.

2. Install 16 Volt, 10 Watt transformer

according to the instructions supplied
with transformer. 

Note: For multiple

mechanical chimes, use a 16 Volt,
15 Watt transformer. Failure to use
a transformer with adequate power
will result in loss of sound or may re-
sult in the system being inoperative.

3. Run two No. 20 AWG or better bell

wires (Heath

location. Strip away 1/2" of insulation
from end of wires. Connect each wire
