All NuTone Master Intercoms use the same door speakers:
- If you are using the chime module (IA-28 or IA-29), you can choose: IS-69 or IS-67 Series (with button) .
- If you are not using a chime module because you want to use an external chime (like one of the long tube jobs), use an IS-70 (no button).
