Quarterly Inspection Requirements

Quarterly fire sprinkler inspections include everything that is normally required for monthly inspections (1–2), plus a few additional items (3–7). The requirements are the following:

  1. Inspect valves to verify that they are in the following condition:
    • In their regular closed or open position
    • Accessible
    • Properly locked, sealed, or supervised
    • Without physical damage
    • Without external leaks
    • Appropriately labeled
    • Alarm drains (alarm valves) or retarding chamber are not leaking
  1. The gauges must be inspected to ascertain that they are in the following condition:
    • For wet Systems, gauges must be inspected each month to ensure they are in good working condition and that appropriate water supply pressure is sustained.
    • For dry systems:
      • The supply side gauge of the dry pipe valve must show that the normal supply water pressure is currently being maintained.
      • The gauge on the quick-opening device, if there is one, needs to indicate the same pressure as the previously mentioned gauge.
      • Gauges on systems with low nitrogen or air pressure alarms must be inspected each month.
  1. The supervisory alarm devices and water flow alarm must be inspected for any physical damage.
  2. The water flow alarm must be inspected and tested by opening up the bypass connection on dry pipe systems and by opening the test connection on wet pipe systems.
  3. If the sprinkler system in question is hydraulic, the hydraulic nameplate must be inspected to ensure that it’s attached and clearly visible.
  4. The fire department connections must be inspected to ascertain that they are clearly visible and without physical damage. The valves and gaskets must also be inspected to ensure that they are not damaged or leaking.
  5. The relief valves and pressure-reducing valves, if provided, need to be inspected, to ascertain that they are:
    • Not leaking
    • In the proper open position
    • In good working order, with hand-wheels unbroken
    • Sustaining appropriate downstream pressure according to their design criteria

Annual Inspection Requirements

Annual fire sprinkler inspections include everything listed above, in addition to the following:

  1. All sprinkler heads must be inspected, including the floor level fitting and pipes.
  2. It must be verified that there are extra sprinkler heads available on site, as well as appropriate tools available for changing out sprinkler heads.
  3. If applicable, the interior of any dry pipe valves must be inspected while resetting.
  4. A main drain water flow test needs to be conducted to ascertain whether or not there has been a change in the condition of the water supply piping. This test is required every quarter if the water supply comes through a pressure-reducing valve or a backflow preventer.
