[QUOTE="Brad Weber, post: 92871, member: 114"] Re: Fire Alarm Cut Off Agreed, there are power switching/sequencing devices and audio processing devices commonly used in commercial/professional audio systems that incorporate the ability to take a dry contact closure, GPIO input, TTL logic or similar from a life safety system and either turn off the power to the related audio devices and/or mute the audio. In fact some devices have connections intended specifically for this purpose and some can provide a form of confirmation via dry contact closures, logic grounds or low voltage DC outputs. But you have to know what is actually required before you can determine what may or may not be a viable solution. [/QUOTE]
