Due to the change of occupancy the sprinkler system should match the requirements of the new occupancy.
If quick response sprinklers are required for code compliance then they need to be changed.

Were having a bit of an issue with an AHJ in converting a Sports Authority to in indoor park. Originally we submitted as Light Hazard because its an assembly occupancy. I didnt necessarily agree with this but anyway The AHJ then wanted all sprinklers changed because they are 286° sprinklers and thus, not permitted in LH. So I spoke to said AHJ and told him I really felt this should be at least an OH occupancy anyway, because of the miscellaneous foam padding and plastics. He agreed (of course verbally and not in writing). We made those changes and a couple more he asked for and thought we were good to go. Today, we received this notice: Mr. Irwin, Just a follow up to our phone call earlier. Thank you for speaking with me earlier. The existing Fire Sprinkler System was designed and engineered to protect a specific hazard for the previous occupancy. There has been concerns about the potential need for reengineering since the beginning of this project. Sprinkler Systems in Assemblies are intended for life safety and are designed as light hazard occupancies with fast activation per NFPA 13. The proposed Fire Alarm System does not include smoke protection and will be primarily activated by the Sprinkler System. The proposed plans are for ordinary group II hazard with high temperature, standard response sprinklers. A delay in activation of the Fire Sprinkler and Fire Alarm Systems, may result in an adverse effect on life safety. This delay may increase the amount of fire damage. Additionally this delay and the proposed 8K sprinklers may increase the amount of water damage. Please provide a signed and sealed letter from the Engineer of Record documenting the effects the proposed fire protection systems will have on occupant notification, occupant evacuation, life safety, and property conservation. Options: * The Engineers letter adequately documents that life safety will not be adversely effected. * The Engineers letter indicates a change in hazard classification and sprinklers. * The Engineers letter indicates the addition of full smoke protection to the fire alarm system. Please be advised that Engineers letter along with the most recent revision will be will be sent out for a third party review by a Fire Protection Engineer. Thank you, Id especially like to know what Matt and Pete think about this. The question is, is it always ok to over protect an occupancy? Assuming this is a LH assembly (which I dont agree it is) can I protect per OH if I want to? As a sprinkler contractor, do I have to take alarm activation in to consideration at all? How would you proceed with this?
