Has anyone setup a pump on a preaction system to prestart at device signal to get it prestarted before valve trip? I have several large preaction systems and am having issues with water delivery times. I need to shave off a few seconds and noticed that the program gives an option to have the pump prestart. We are required on this project to provide the water delivery calculations, so I cannot use 7.2.3.4 to avoid the water delivery time requirement.
My specific question is, does anyone know of any concerns the contractor should have for doing this? Are there any operations/maintenance concerns? Are false trips a problem?
