Special Instructions:

In general, it is recommended that the servicing of these systems be entrusted to
representatives of fire extinguishing installation companies.  The work required
by this procedure may cause the activation of an alarm and/or a supervisory
signal.  The field office manager and control center or fire department that will
receive the alarm or signal must be notified prior to start of work.  When
replacement cylinders are received from supplier, check that hydrostatic test
date is current.

Items to Check & Initial Completion:

1.___ Check each cylinder for the date of the last hydrostatic test (all dates
      are stamped on cylinder).
2.___ Replace those cylinders for which the elapsed time exceeds:
      a) Carbon dioxide - 12 years
      b) Halon - 20 years
      c) Dry Chemical - 12 years
3.___ Weigh or check pressure on remaining cylinders.  Replace if:
      a) Carbon dioxide - weight loss is 10% or greater.
      b) Halon - weight loss is 5% or greater or if pressure loss (adjusted for
         temperature) is 10% or greater.
      c) Dry Chemical - weight loss in gas expellent cylinder exceeds acceptable
                        limit on system (or the cylinder) or if pressure gauge
                        indicates "inoperable" range.
4.___ Check the entire piping system (including cylinders) for leaks,
      obstructions, physical damage, and proper support.  Examine all nozzles to
      insure they are properly positioned, clean, and not clogged.  Replace or
      repair as necessary.  Replace seals on all systems.  For dry chemical
      systems, check dry chemicals in storage container(s) to be sure they are
      free flowing and without lumps (this does not apply to stored pressure
      systems).  Replace old chemical agent every 12 years or earlier if
      necessary by annual inspection.  Replace all fusible alloy type fixed
      temperature elements (fusible links).
5.___ For all systems, test (and clean if necessary) all mechanical, manual, and
      automatic detection equipment and actuating devices according to
      manufacturer's instructions.  Replace or repair those yielding
      unsatisfactory performance.
6.___ For all systems, test ("dry run" trip test) the system in accordance with
      the manufacturer's instructions.
7.___ Check for proper operation of all alarms and signals at the fire alarm
      control panel.
8.___ Restore system to "ready" status and record data on system tag.
