How do you mess up: 8.3.2.1 Unless the requirements of 8.3.2.2, 8.3.2.3, 8.3.2.4, or 8.3.2.5 are met, ordinary and intermediate-temperature sprinklers shall be used throughout buildings.
Intermediate can be used throughout unless other sections require a different temperature rating.

Is it permissible to install intermediate temperature sprinklers throughout all spaces (except those that would specifically require a high temp sprinkler due to other sections)? The specific question arises because we have ordinary temperature sprinklers throughout most areas, and intermediate temp sprinklers in mechanical closets and laundry rooms in the dwelling units. The AHJ states that since the areas (mech closets and laundry areas in the dwelling units) are conditioned spaces, that we must use ordinary temperature rated sprinklers. He states that Table 8.3.2.5(c) over-rides the flexibility provided by 8.3.2.1 which allows ordinary or intermediate temp sprinklers throughout buildings. This has been common practice to install the intermediate temp sprinklers in these areas. This is the first time that this plan reviewer has ever brought this up. Some contractors in this area are moving toward intermediate temp sprinklers throughout in residential areas for various reasons. -- Travis Mack, SET MFP Design, LLC 2508 E Lodgepole Drive Gilbert, AZ 85298 480-505-9271 fax: 866-430-6107 email:[email protected] http://www.mfpdesign.com https://www.facebook.com/pages/MFP-Design-LLC/92218417692 Send large files to us via: https://www.hightail.com/u/MFPDesign _______________________________________________ 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
