Listing in the PML does not guarantee a product willautomatically be listed in a project's documents or specifications.Conditional Approval: Listed manufacturer's product may be used on select U-M projects,however approval from the respective A & E Technical Committee must first be obtained. Ifapproved, it may be listed as approved in the project's contract documents or specifications.Manufacturers in the Conditional Approval category have gone through successfulpreliminary review, but Technical Committee requires additional in-service input prior to finalcategory listing.Under Consideration: Listed manufacturer's product is being evaluated. The productshould not be included in U-M projects.SECTION 211313 (15300) - WET-PIPE SPRINKLER SYSTEMSPreaction SystemsSiemens (Pyrotronics), Notifier, VikingPiping - GroovedAnvil Gruvlok, VictaulicSprinkler HeadsReliableTycoVikingVictaulicTamper SwitchesGrinnell, System Sensor, VictaulicValves - Fire Protection, Detector esValves - Fire Protection, Zone anical TradesPreferred Manufacturers ListPage 2JanuaryFebruaryApril, 2014
