• IMPORTANT: If the door chime is connected to a NuTone Radio-
Intercom System, the chime tones will be heard at all inside and
outside speaker locations (chime will not sound at door speaker).
The Door Chime must be wired in accordance with the Chime-To-
Intercom information that is included in this literature.
• If a NuTone Radio-Intercom System is not used, a door speaker
may be installed at the outside of the front door
so chime tones will be heard at that location.
• Use the NuTone transformer that has been supplied with the door
chime.

want to install a ring doorbell to my nutone model la-174 doorbell. Where is the trans connection made?
The NuTone LA-174 door chime requires a transformer for operation. To connect a Ring doorbell to the NuTone LA-174, follow these steps:
1. Check Transformer Voltage: Ensure the transformer provides the correct voltage for both the Ring doorbell and the NuTone LA-174. Ring devices typically require 16-24V AC, while the NuTone LA-174 operates on a transformer.
2. Wiring Setup:
- Connect the transformer’s white and black wires to the matching house supply wires.
- Run a wire from the transformer’s output terminals to the Ring doorbell’s power input.
- Connect the Ring doorbell’s wiring to the NuTone LA-174’s chime terminals.
3. Integration Considerations:
- If the NuTone LA-174 is connected to a NuTone Radio-Intercom System, the chime will sound at all speaker locations except the door speaker.
- Use approved wiring methods to avoid shorts or damage.
4. Testing:
- Turn the power back on and test the Ring doorbell.
- Ensure the NuTone chime activates properly when the Ring doorbell button is pressed.
If the Ring doorbell does not ring the NuTone chime correctly, you may need a Ring Chime Connector or a compatible relay to ensure proper function.

@Mr. Anderson the Ring instructions I have state to connect one wire from the pro power kit to the front door terminal and the second wire to the "trans" terminal. My unit does not have a "trans" terminal. Is it possible then to connect one wire from the power kit to the front door terminal and connect the second wire to the white wire from the transformer?
