We have the following information in our policy bulletins:
I. Purpose A. To establish policy for installation of Post Indicator Valves (PIV) on fire service mains. II. General Instructions: A. A PIV shall be installed for control of sprinkler system water supplies in accordance with the reference standard. B. PIV installations shall be supervised by the fire alarm control panel on a zone or address point dedicated to the tamper monitoring and shall be locked in the open position C. Where installation of a PIV is determined not feasible due to geographic or other extenuating constraints, a Wall Indicating Valve (WIV) may be utilized at the discretion of the fire code official. D. Inspection, testing, and maintenance of a PIV shall be in accordance with the current edition of NFPA 25. E. PIV padlock keys shall be kept in the spare sprinkler head box for accessibility. III. References 2012 International Fire Code, Section 507 Fire Protection Water Supplies NFPA 24: Standard for Installation of Private Fire Service Mains and Their Appurtenances NFPA 25: Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection System Engineering Design Standards – Standard Detail No. 900.15 From: Sprinklerforum [mailto:[email protected]] On Behalf Of Owen Evans Sent: Monday, January 23, 2017 11:26 AM To: [email protected] Subject: PIV Supervion, lock or tamper switch? As most of you know, I work exclusively with 13D systems. I do on occasion get questions on the big boy systems, 13 and 13R. The property in question is a boutique hotel, two buildings. One building is a two story, fifty room hotel and the other building is two story, restaurant on the first floor and banquet facility on second floor with a roof deck. Each building has a FDC and a PIV. I am in California which is under the 2013 IFC. I recently had the question asked "does the PIV require electrical supervision?" NFPA states a lock is adequate, the 2013 IFC states electrical supervision is required, with exceptions. I get different answers form different people. I'm thinking it's the more restrictive 2013 IFC. Which is it? Thank you, Owen Evans
