The M&S NR8P Ceiling Intercom Speaker is compatible with M&S intercoms and NuTone NM100 and NM200 Series Intercoms and is ideal for large rooms to provide greater music volume.
The NR8P should be installed in rooms with a MVC1 Volume Control when intercom functions are not needed and requires the Rough-In Model NR8 Ceiling Intercom Speaker Mounting Ring for installation.
