Lower/Quiet/Silence Tailwind Controller Audio Volume and Light Flashing

    Unfortunately no. The safety standard UL 325 dictates the decibel level, frequency, and duration of the audible warning as well as the brightness, color, and duration of the flashing. If we allowed you to override it we would be in violation of the law.

    I have personally installed systems from competitors that don't have the warning and I can honestly say it is deeply concerning. Not only are they illegal, they're downright scary. To have the door start closing suddenly without any warning is definitely not safe.

    Fair enough! I was not aware of this. Just out of curiosity, but is this a US, Canadian, or International standard? Thanks!
