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.
