    Trane AH541

    I am trying to reset all AH541's after a fire alarm. The site has some version #1 and some version #2. I first used CPL to shutdown all AHU's when there was a fire alarm. The problem is with the verson #2 AH541's. They lock out on airflow before the CPL shuts down the AHU. Does anyone have a good CPL program to reset all the AH541's after a fire alarm?

    Thanks

    I believe you can make BO's and reference them to the alarm reset point in the ah541, then just have your cpl toggle that point after the fire alarm goes away.
