This document provides installation instructions for the NuTone Built-In Apartment Speaker, specifically models in the N482BX SERIES and DIRECT-A-COM 3. It covers general installation, multi-floor and garden apartment system wiring, and individual apartment speaker wiring, along with a limited two-year warranty.

Function Description:

The NuTone Built-In Apartment Speaker is designed for use in multi-floor and garden apartment complexes as part of an intercom system. Its primary function is to allow communication between individual apartments and a main entry point, often incorporating a buzzer for visitor notification and a door release switch for remote entry control. The system facilitates communication and access control within an apartment building environment.

General Installation Information:

The apartment speaker is designed for either built-in or surface mounting. For built-in installation, it should be mounted in a NuTone rough-in frame. For surface mounting, a NuTone surface mount frame is required. It is crucial to install all necessary interconnecting wires and cables when the rough-in frames are mounted. For detailed system wiring diagrams concerning optional Direct-A-Com 3 installations, users should refer to the Installation Instructions for the NuTone Direct-A-Com Series 3.

Multi-Floor & Garden Apartment Installation:

Each Apartment Speaker connects to a speaker at the main entry. The main entrance equipment can include:

1. An Entrance Directory, as illustrated in Figure 1 of the manual.
2. Mailboxes equipped with pushbuttons and either built-in door speakers or surface-mounted door speakers.
3. Separate pushbuttons with either built-in or surface-mounted door speakers.

System Wiring (Recommended NuTone Wire):

1. Riser Wiring: Refer to Figure 1 for the riser wiring detail. A 3-twisted pair cable (NuTone IW-6) is common between the Central Amplifier and all Apartment Speakers.
2. Common System Wiring:
   • An 18 gauge wire is used between the Speaker Door Release Switch and the Electric Door Release.
   • An 18 gauge, 16vAC wire connects the Transformer to the Speaker Buzzer and the Speaker Door Release Switch.
3. Individual Apartment Pushbutton Wiring: An individual 18 gauge wire runs between each Apartment Pushbutton and the Speaker Buzzer.

Apartment Speaker Wiring (Refer to Figure 2):

1. 3-Twisted Pair Cable Connection: Connect the ORANGE pair to the ORN terminals, the RED pair to the RED terminals, and the BLACK pair to the BLK terminals. These connections match color-coded wires to color-coded terminals.
2. Buzzer and Door Release Switch Power: Connect one BROWN wire from the Buzzer and one BROWN wire from the Door Release Switch to an 18 gauge, 16vAC wire originating from the Transformer.
3. Buzzer Pushbutton Connection: Connect the other BROWN wire from the Buzzer to an 18 gauge wire from the individual pushbutton located at the main entry.
4. Door Release Connection: Connect the other BROWN wire from the Door Release Switch to an 18 gauge wire from the DR-1 Electric Door Release at the main entry.
   • NOTE: Wire connectors, or splice and tape, should be used for wire connections in steps 2, 3, and 4.
