We have a customer that has a 7 story building with a fire pump (only 50 psi @ 750 with a street static of 52). It has a problem with the controller and parts are no longer available. We gave them a price to change out with a new controller, like for like, which includes a transfer switch. Now they want a price to replace without a transfer switch. I see that NFPA 20 (2007) 10.8.1 says to install a transfer switch if required by the AHJ or 9.3.2. 9.3.2 lays out the requirements for alternate power. I see that 9.3.1 says an alternate power is required when the height of the building is beyond the pumping requirements of the fire dept. Of course as part of the contract he wants us to get the approvals for removing the transfer switch. I am trying to see what I am up against in trying to remove this switch. *Jay Stough* NICET IV LAYOUT NICET III ITM _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
