Transformer C907

we offer. Ideal for large homes with
multiple chimes. 16-volt 30VA for up
to three chimes.

Install a junction box where
the chime is to be installed.
Step Two:
Wire the transformer as you
would any common receptacle.
Step Three:

to the junction box. Connect low
voltage wires to the chime and mount
it directly to the transformer.

Builder Kits – Junction Box Transformer
Now, rather than mounting the transformer in a remote location and running wires to various points, NuTone
®
puts everything in one package.
With our patented new system, just run the wire, connect and drop the entire transformer in the junction box. Two simple low voltage
connections later and the chime is running. NuTone ends the back and forth, up and down runaround by keeping everything conveniently
packaged in one location. Choose a kit with one or two standard buttons, or one stucco button.

two chimes.

Quick install transformers, built to last.
Not all transformers are equal. In fact, our transformers
feature an easy-to-install lock-mount or wall-mount that
can reduce installation time by 25%. A second unique
feature that provides added reassurance is the thermal
cut-off switch designed to shut off the door chime
system in the event of excessive temperature.
