INSTALLATION
Remote Station Wiring
An individual 4-wire cable (IW-4UL) must be connected from
each remote station or remote control location to the master
station's terminals.
• Maximum station wire length: 150 feet .
• Maximum total of IW-4UL cable per system: 600 feet.
• Never bundle cables between master station and remote
stations/door speakers together. Cables that are bundled
together will reduce intercom/monitor volume and cause
squealing/noise.
• Never use 4-wire telephone cable or other 4-wire cable.
Use only NuTone IW-4UL flat ribbon cable. The use of
telephone cable or other 4-wire cable will reduce intercom
monitor/volume and cause squealing/noise.
IMPORTANT: NuTone cannot be responsible for improper
system operation that results from interference generated
by light dimmers, fluorescent lighting fixtures, and similar
electrical products. Such interference must be corrected at
the source.
To help reduce this interference, all wiring connected to the
master must be placed at least 12 inches from any A.C.
power wiring.
Maximum Number of Remote
Stations
The master station will accommodate a maximum of (6) remote
stations/remote controls/volume controls and 3 door speakers.
IMPORTANT: Never use standard 8 ohm stereo speakers or
the master station will be damaged.
