NOTE TO INSTALLER: Do not discard these installation instructions. Please transfer all installation instructions, warranty registration and homeowner’s manual to the homeowner.
PRECAUTIONS AND GUIDELINES
The NuTone IMA-4406 master station has been designed for ease of installation. Please read and follow ALL installation instructions, guidelines and precautions. Any deviation from these instructions or miswiring combinations may result in unit failure and void of warranty.
WARNING!
120 Volt AC Power to Transformers in the IR-105 Rough-in MUST Remain OFF until ALL System Wiring at the Master and Remote Stations is Complete.
•Observe all local building regulatory codes in your area.
•All screw terminals at the master and remote stations must be secure.
•Observe all color code connections of wires when connecting the remote stations to the master.
•The IMA-4406 is designed to be installed with only NuTone specified wire. No other wire should be used. The use of wire other than NuTone wire will void all NuTone warranties and may result in faulty installation and improper operation.
IMPORTANT WARNING!
THE POWER TRANSFORMER CONTAINS AN INTERNAL FUSE.
DO NOT SHORT THE LOW VOLTAGE CONNECTING SCREWS OF THE TRANSFORMER OR THE TRANSFORMER WILL BE DESTROYED!
WIRING SPECIFICATIONS
See the IR-105 master rough-in frame installation instructions for detailed wiring information.
Use NuTone IW-6, 3 twisted pair for connecting:
•Remote controls to master
•Remote stations to master
Use NuTone IW-2, 22 ga. twisted pair for connecting:
•Door speakers to master
•Remote controls to speakers
•Speaker volume control (IC901) to master
•Speaker volume control (IC901) to speakers
•Electronic chime audio output to master
•Pushbutton to chime module
Use NuTone S-143, 18 ga. twisted pair for connecting:
•Pushbutton to electronic chime
•Electronic chime to chime transformer
Use Nº14/2 power cable with ground, Class 1 UL Listed (Observe local codes) for connecting:
• Transformers to 120v AC
Use shielded audio cable for connecting external audio sources to the master station.
REMOTE STATION WIRING
An individual 6-wire cable (IW-6) must be connected from each remote station or remote control location to the master station’s terminal board.
Maximum station wire length: 750 ft.
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 CONNECTIONS TO THE MASTER MUST BE PLACED AT LEAST 12 INCHES FROM ANY AC POWER WIRING. AVOID RUNNING INTERCOM WIRES PARALLEL TO AC POWER WIRING.
Maximum total length of IW-6 cable per system: 4,000 ft.
MAXIMUM NUMBER OF REMOTE STATIONS
The master station will accommodate up to 9 connections at the terminal board. These connections can be any combination of remote stations, remote controls or volume
NOTE: NEVER connect more than one remote station to a set of screw terminals.
controls. It will also accommodate 3 door speaker connections.
If more than 9 stations are required, use the optional
Model Nº IAA-440 expansion kit. This will allow an additional 6 connections at the master.

INSTALLATION (Continued)
WARNING! NEVER EXCEED A TOTAL OF 15 NUTONE 25 OHM SPEAKERS ON THIS SYSTEM.
WARNING! NEVER USE STANDARD 8 OHM STEREO SPEAKERS ON THIS SYSTEM. USE ONLY NUTONE SPECIFIED SPEAKERS ON THIS MASTER.
MOUNTING THE TERMINAL BOARD
1.Remove and clean any drywall debris or dust from the rough-in before beginning installation.
2.Refer to Figure 1. Locate the terminal board in the left rear section of the rough-in frame.
3.Use four (4) Nº 6 x 3⁄8“ screws supplied to secure the terminal board to the rough-in frame.
4.Make certain the lower right-hand screw is secure and snug against the ground lug which covers the mounting hole in the terminal board. Do not bend ground lug.
Make sure it is positioned between the screw and terminal board.
IMPORTANT |
|
▲ |
▲ |
DO NOT APPLY POWER TO THE SYSTEM UNTIL ALL CONNECTIONS ARE COMPLETE AT THE MASTER AND REMOTE STATIONS.
FIGURE 1 |
2.Refer to Figure 2. Connect the IW-6 cable from each remote to the appropriate set of terminal screws at the master station’s terminal board. When connecting the cable to the terminal board, be sure to observe the matching of all color codes.
Connect: RED to RED RED/WHT to RED/WHT BLK to BLK
BLK/WHT to BLK/WHT ORN to ORN ORN/WHT to ORN/WHT
Only connect one remote to each set of screw terminals. After completing all connections, check for any shorted wires. Dress cables flat against the terminal board to allow space for the master station to be properly secured.
