INSTALLATION (Continued) 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. 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.
INSTALLATION (Continued) CONNECTING VOLUME CONTROL WIRING PREPARING MASTER STATION PANEL FOR OPTIONAL DOOR RELEASE PUSHBUTTON Refer to Figure 4. If a NuTone Volume Control is installed in the system, connect the control’s IW-2 wiring to the ORN and ORN/WHT screw terminals at the master station. Only ONE NuTone speaker may be connected to each volume control. Each volume control/speaker counts as a remote station. Remember: The maximum remote connections to the Master Station is 9.
INSTALLATION (Continued) 2. Refer to Figure 10A and 10B. For rough-in frames which are recessed into the wall opening, insert two (2) shoulder screws (provided) into the front two holes in the rough-in frame. For rough-in frames which are mounted flush with the wall, insert two (2) shoulder screws into the back two holes in the rough-in frame. Model IA-29 Only 1. Refer to Figure 8. Locate the chime selector switch mounting bracket in the master unit.
