NuTone IA-29, IA-28 operating instructions Installing the Amplifier, Connection to RADIO-INTERCOM

INSTALLING THE AMPLIFIER

1.Determine exact location for all components. Check plans against the “Installation Don'ts.”

2.Run designated wire to component locations, including power wiring to transformer and low-voltage wiring between transformer and amplifier.

3.Make wire connections and mount components. Note that some components (especially speakers) may require a rough-in frame.

NOTE: After the first two speaker stations are wired, supply power to the system and test for proper operation. Wire and test the remaining speaker stations one at a time.

NOTE: If UL listed wire is required, use IW-6-UL and IW-2-UL.

MOUNTING THE TRANSFORMER

CAUTION: Do not install the transformer in attic, crawl space, or on lighting fixture. High ambient temperature will cause transformer to cut out.

IMPORTANT: If replacing an IM-516 with IMA-516, replace transformer with Model 301-T transformer

1.In keeping with local electrical code, mount 301-T transformer in one of the following locations: fuse box, circuit breaker box, or utility box in an accessible area.

2.Do not cover transformer with insulation. Do not use transformer for other appliances.

MOUNTING THE AMPLIFIER

The amplifier is surface-mounted to a finished wall, or mounted on a single-gang outlet box. It must be located in an area that is accessible for making adjustments and for servicing if required. Two mounting holes are provided in the amplifier base plate.

CONNECTION TO RADIO-INTERCOM

This is the primary application. By connecting a non-intercom IMA-516 speaker system to a NuTone Radio-Intercom System (2000, 3000, 3300, 4000 or 5000 model series), radio/music can be provided to selected locations where intercom is not needed. Example: A doctor's office may need radio-intercom in the office areas and radio/music only in the waiting-reception area.
