How To | Use a Q-SYS Amplifier's GPIO to Mute a System from a Fire Control Panel
Learn how to easily utilize a Q-SYS Amplifier's GPIO to seamlessly mute a system in the event of a fire emergency, ensuring safety and compliance with fire control panel regulations.
Procedure
For fire control panels that supply a dry contact closure to mute the system upon a fire alarm triggering you need to wire up the GPIO 1 set as a Digitial Input and a ground pin on the amplifier's GPIO ports to the Fire Alarm panel and then in the design use a Position Invert on the GPIO input wired inline between the System Mute and the GPIO 1 control pin.
This works for all Q-SYS Amplifiers, including the CXD-Q, SPA-Q, and CX-Q model lines.
