5-4.3 Inspection Procedures, Semi-Annual
5-4.3.1 PRESSURE SWITCH TEST
1. Contact the appropriate personnel and obtain authori-
zation for a shutdown.
2. Ensure that the hazard area operations controlled by
the pressure switch are operative.
3. Manually operate the switch by pulling up on the plunger
and verify that the hazard area operations controlled
by the pressure switch shut down.
4. Return the pressure switch to the SET position.
5. Reactivate all systems that were shut down by the pres-
sure switch (such as power, ventilation systems and
compressors).
5-4.3.2 ELECTRIC CONTROL HEAD TEST
Electric control heads must be tested semiannually for
proper operation. This test can be performed without dis-
charging the FM-200 cylinders. Test one hazard area at a
time before proceeding to the next, as follows:
CAUTION
!
All control heads must be removed from
FM-200 cylinders and nitrogen pilot
cylinders prior to testing to prevent accidental
cylinder discharge.
1. Remove all electric control heads from all FM-200 cyl-
inders and nitrogen pilot cylinders serving the hazard
area being tested. Let the electric control heads hang
freely from the flexible electric conduit connections.
Leave all pressure operated control heads and pilot
actuation hoses attached to the cylinders.
2. Operate FM-200 system electrically. This can be ac-
complished by actuation of the FM-200 system at the
system control panel or by manual operation of an elec-
tric pull station.
3. Ensure all electric control heads have operated, that
is, the indicator on the electric control head has moved
to the RELEASED position, or in the case of a control
head (P/N 486500-01) observe that the actuating pin
has moved to the fully actuated position. If any control
heads have not operated, check the circuit for electric
continuity to these particular heads and repeat the test.
Replace all damaged heads. Repeat the test if any con-
trol heads have been replaced.
CAUTION
!
Electric control heads must be reset manually
before reconnecting to the cylinder valves.
4. Observe the instructions on the caution label attached
to each electric control head (P/N 486500-01). Replace
any damaged heads which fail to reset properly before
reconnecting to cylinders. Reattach all electric control
heads to the threaded port on the cylinder valve or pres-
sure operated control head. Tighten the swivel nut
securely. Make certain each electric control head is
in SET position before reconnecting to cylinders.
Failure to follow this procedure will result in acciden-
tal FM-200 discharge.
5-4.4 Inspection Procedures-2 Year
WARNING
!
Do not use water or oxygen to blow out pipe
lines. Using oxygen is especially dangerous
since even a minute quantity of oil may cause
an explosion.
1. Remove any nozzles from the piping to allow foreign
matter to blow clear.
2. Remove all pressure operated control heads from the
FM-200 cylinders.
WARNING
!
Do not disconnect the flexible hose from the
pressure operated control head. If FM-200
accidentally discharges, the unattached flexible
hose will whip around and may damage
equipment and cause severe bodily injury.
3. Open the distributing valves and keep them open long
enough to ensure the pipes are clean.
4. Blow out all distribution piping with air or nitrogen to
ensure it is not obstructed.
5. Reconnect all control heads.
5-5 INSPECTION AND RETEST
PROCEDURES FOR FM-200 CYLINDERS
A cylinder that is damaged or corroded should be emp-
tied, retested and restamped in accordance with
DOT CFR Title 49, Section 173.34 (retesting is explained
in Paragraph 5-5.3).
CAUTION
!
These guidelines do not apply to cylinders
containing a commodity other than FM-200.
All Kidde FM-200 cylinders are designed, fabricated, and
factory tested at 1000 PSIG (68.9 bar gauge) in compli-
ance with DOT CFR 49 4BA-500 or 4BW-500 as stamped
on each cylinder.
Two sets of regulations will apply to periodic inspection and
test procedures depending on the following:
