Voltage Meter According to NFPA 25, What is the typical size of an impairment tag? 4in x 6in
The Hydraulic design information sign for a standpipe system, when provided, shall be at what interval in order to verify that it is attached and is legible? Annualy Obstruction investigations should be recommended when what situations occur? After extended period of being shut down and returned to service, drains or inspectors test plugged by foreign material, and/or obstructive material observed during drain test When preforming a churn test (no flow condition) on a Diesel Fire Pump, what is the minimum run time? 30 Minutes How frequently shall a Vane Type water flow switch be tested?

Central Monitoring Station
What course of action is required when testing fast response type sprinklers that have been in service for 20 years? replaced or representative samples shall be tested and the retested at 10 year intervals How often are monitor nozzles to be inspected? semi-annually Who is responsible for maintaining all sprinkler system reports? Building/property Owner How frequently shall the interior of a dry pipe valve be inspected? Annually when the trip test is conducted According to NFPA 25, what is determined through inspection and periodic testing of water-based fire systems? Action needed to fix what has been changed An antifreeze loop has a capacity of 350 gallons. How many points should it be tested at? 4, Both most remote point and where the system meets with the water supply. Also, where antifreeze systems have a capacity lager than 150 gal, test at one additional point for every 100 gal shall be made. During a planned system impairment, where should the impairment tag be posted?

According tp NFPA 25, what is the maximum loss (in psi) allowed? 3 psi How frequently should the main drain test be run on pressure reducing valves and backflow preventors installed and acting as the sole source of the water supply? Quarterly What is the time interval for the internal inspection of non-metallic pipe? Not required for nonmetallic pipe At what elevation shall the test pressure be measured while preforming a hydrostatic test on a manual dry standpipe? The lowest elevation point in the system How often are pressure gauges on a pre action system required to be tested or replaced?
