5-4.2.1 GENERAL INSPECTION
Make a general inspection survey of all cylinders and equip-
ment for damaged or missing parts. If the equipment re-
quires replacement, refer to Paragraph 5-6.3.
5-4.2.2 HAZARD ACCESS
Ensure access to hazard areas, manual pull stations, dis-
charge nozzles, and cylinders are unobstructed and that
nothing obstructs the operation of the equipment or distri-
bution of FM-200 agent.
5-4.2.3 INSPECT HOSES
Inspect 1/4-inch flexible actuation hoses for loose fittings,
damaged threads, cracks, distortion, cuts, dirt and frayed
wire braid. Tighten loose fittings and replace hoses with
stripped threads or other damage. If necessary, clean parts
as directed in Paragraph 5-6.1. Inspect the adapters, cou-
plings and tees at the FM-200 cylinder pilot outlets and
tighten couplings if necessary. Replace any damaged parts.
5-4.2.4 INSPECT PRESSURE CONTROL HEADS
Inspect FM-200 cylinder pressure operated control heads
for physical damage, deterioration, corrosion, distortion,
cracks, dirt and loose couplings. Tighten loose couplings.
Replace damaged caps. Replace the control head if dam-
aged. If necessary, clean as directed in Paragraph 5-6.1.
5-4.2.5 INSPECT ELECTRIC CONTROL HEADS
Inspect the FM-200 cylinder electric control heads for dam-
age, corrosion, and dirt. Check the control heads' flexible
electrical line for wear and damage. Check the control head
for loose coupling and tighten if necessary. Check that the
indicator is in the SET position, the pull pin is installed in
the manual lever, and the seal wire is intact. Replace the
control head if damaged. If necessary, clean as directed in
Paragraph 5-6.1.
5-4.2.6 INSPECT CYLINDER AND
VALVE ASSEMBLY
Inspect the FM-200 cylinder and valve assembly for
leakage and physical damage such as cracks, dents, dis-
tortion and worn parts. Check the burst disc and pressure
gauges for damage. Replace damaged gauges or burst
disc per Paragraph 6-2.4. If the gauge pressure is not nor-
mal (360 PSIG at 70°F [25 bar gauge at 21°C]), remove
and recharge the cylinder as instructed in Paragraphs 5-7
and 6-3. If damaged parts are found on the FM-200 cylin-
der or cylinder valve, replace the FM-200 cylinder. If nec-
essary, clean the cylinder and associated parts as directed
in Paragraph 5-6.1.
5-4.2.7 INSPECT BRACKETS, STRAPS, CRADLES
AND MOUNTING HARDWARE
Inspect the FM-200 cylinder brackets, straps, cradles and
mounting hardware for loose, damaged or broken parts.
Check the cylinder brackets, straps and associated parts
for corrosion, oil, grease and grime. Tighten any loose hard-
ware. Replace damaged parts. If necessary, clean as di-
rected in Paragraph 5-6.1.
5-4.2.8 INSPECT DISCHARGE HOSES
Inspect he flexible discharge hoses for loose fittings, dam-
aged threads, cracks, rust, kinks, distortion, dirt and frayed
wire braid. Tighten loose fittings and replace hoses with
stripped threads. If necessary, clean as directed in Para-
graph 5-6.1.
5-4.2.9 INSPECT ACTUATION LINE
Inspect the nitrogen actuation line (if used) and support
brackets for continuity, physical damage, loose fittings,
distortion, cracks or cuts. Tighten loose fittings. Replace
damaged parts. If necessary, clean as directed in Para-
graph 5-6.1.
5-4.2.10 INSPECT DISCHARGE NOZZLES
Inspect discharge nozzles for dirt and physical damage.
Replace damaged nozzles. If nozzles are dirty or clogged,
refer to Paragraph 5-6.1.
CAUTION
!
Nozzles must never be painted.
Nozzles must be replaced by nozzles of the
same part number. (A part number is located
on each nozzle.) Nozzles must never be
interchanged since random interchanging of
nozzles could adversely affect proper FM-200
distribution and concentration within a
hazard area.
5-4.2.11 INSPECT PULL STATIONS
Inspect all manual pull stations for cracks, broken or cracked
glass plate, dirt or distortion. Inspect the station for signs of
physical damage. Replace damaged glass. Replace the
station if damaged. If necessary, clean as directed in Para-
graph 5-6.1.
5-4.2.12 INSPECT PRESSURE SWITCHES
Inspect pressure switches for deformations, cracks, dirt or
other damage. Replace the switch if damaged. If neces-
sary, clean the switch as directed in Paragraph 5-6.1.
