How to Install the Atkinson Dynamics Panel Mount Intercom AD-26P

This guide provides step-by-step instructions for installing and configuring the Atkinson Dynamics AD-26P panel mount intercom, ensuring proper wiring and setup for optimal performance.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, 1K, 1W resistor (optional)

  1. Prepare the mounting location

    Cut an opening and drill four mounting holes in the customer-supplied panel according to the specified dimensions. Ensure the holes are 0.191" in diameter to accept #8 mounting screws.

  2. Mount the intercom

    Insert the panel mount intercom into the prepared opening and secure it by installing screws in the four mounting holes. Ensure the intercom is level and firmly attached.

  3. Connect power and audio wires

    Connect the power wires labeled 'PWR +' (Black) and 'PWR -' (White) to the appropriate power source. For 120/240VAC models, connect the green/yellow wire labeled 'EGND' to earth ground. Connect the audio wires labeled 'SPK' (White/Brown) and 'COM' (White) to the local speaker/microphone.

  4. Connect additional audio lines

    If applicable, connect the audio wires labeled 'AUD' (Black or Green) and 'COM' (White) to the corresponding wires on other intercoms in the system. For models with the '-M44' option, connect 'REM SPK' (Black) to a remote speaker.

  5. Install optional resistor

    If desired, install the included 1K, 1W resistor across the audio lines to reduce noise. Only one resistor is needed for the entire system.

  6. Verify connections and power on

    Double-check all connections for accuracy and secure any loose wires. Once verified, restore power to the intercom and test functionality.
