we have 2 range hood control panels in same commercial kitchen. each controlling separate exhaust fans and MAU's. we have a separate ansul system on each with its own microswitch. however theres only one gas solenoid for whole kitchen. first question:I know where to land on ansul microswitch from control panel., does the system activate upon loss of power to microswitch or upon power to microswitch. second question: one solenoid with 2 control panels needing to shut off gas upon activation of either one. does the solenoid require 120v to let gas flow because I can just set a definite purpose contactor between the the separate ckts from different panels one holding the coild of the other so if either was activated solenoid would close
