How to Install the ASUH-024 Controller

This guide provides step-by-step instructions for installing and configuring the ASUH-024 controller in a fire alarm system.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, Conduit plugs

  1. Mount the controller

    Secure the ASUH-024 controller to a flat surface using #10 x 1" wood screws or #10 screws with lockwashers and nuts for metal surfaces. Ensure the speaker projector is pointed horizontally or slightly downward.

  2. Make electrical connections

    Use 12 to 18 AWG wire to connect the power source to the controller. Strip no more than 0.25 inches of insulation from the wire ends and connect the positive and negative leads to the appropriate terminals on the connector plug.

  3. Install the tone card

    Plug the desired tone card into the socket on the controller. Ensure the neoprene rubber cover gasket is properly seated to maintain a seal, then reinstall the housing cover.

  4. Test the installation

    After installation, test the system to verify that the ASUH-024 operates correctly. Adjust the internal volume control if necessary using a slotted screwdriver.
