Inspection and Maintenance Section
FM-0723-0-7H
Annually:
TEST:
Control Valve:
Each control valve shall be operated through its full range
and returned to its normal position.
Main Drain:
A main drain test shall be conducted to determine whether
there has been a change in the condition of the water supply
piping and control valves.
Operational Test:
Operational tests shall be conducted to ensure that the ICAF
system responds as designed, both automatically and
manually.
The test procedures shall simulate anticipated emergency
events so the response of the ICAF system can be
evaluated.
Protection shall be provided for any devices or equipment
subject to damage by system discharge during tests.
Where the nature of the protected property is such that CAF
cannot be discharged for test purposes, the trip test shall be
conducted in a manner that does not necessitate discharge
in the protected area.
Where the nature of the protected property is such that CAF
cannot be discharged unless protected equipment is shut
down (e.g., energized electrical equipment), a full flow
system test shall be conducted at the next scheduled
shutdown. In all cases, the test frequency shall not exceed
3 years.
Where discharge from the system discharge devices would
create a hazardous condition or conflict with local
requirements, an approved alternate method to achieve full
flow conditions shall be permitted.
Response Time:
Under test conditions, the automatic fire detection systems,
when exposed to a test source, shall operate within the
requirements of NFPA 72, National Fire Alarm Code, for the
type of detector provided and the response time shall be
recorded.
Discharge Time:
The time lapse between operation of detection systems and
water delivery time to the protected area shall be recorded
for open discharge devices.
Discharge Patterns:
The discharge patterns from all of the nozzles shall be
observed to ensure that patterns are not impeded by plugged
nozzles and to ensure that nozzles are correctly positioned
and that obstructions do not prevent discharge patterns from
covering surfaces to be protected.
Where obstructions occur, the piping and nozzles shall be
cleaned and the system retested.
Pressure Readings:
Pressure readings shall be recorded at the main control valve
and the CAF outlet.
Readings shall be compared to the design pressures to
ensure the original system design requirements are met.
Multiple Systems:
The maximum number of systems expected to operate in
case of fire shall be tested simultaneously to check the
adequacy of the water supply.
Manual Operation:
Manual actuation devices shall be tested.
Return to Service:
After the full flow test, the system shall be returned to service
in accordance with the instructions described in this manual.
Low points in the ICAF system shall be drained after each
operation.
Records indicating the date the ICAF system was last tripped
and the tripping time as well as the individual and
organization conducting the test shall be maintained at a
location or in a manner readily available for review by the
Authority Having Jurisdiction.
MAINTENANCE:
Strainers:
Priming line strainer (basket or screen) shall be removed,
cleaned and inspected.
Every 5 years:
TEST:
Gauges:
Gauges shall be tested every 5 years by comparison with a
calibrated gauge. Gauges not accurate to within 3 percent of
the full scale shall be recalibrated or replaced.
INSPECTION:
Flow Control Valve:
The interior of the flow control valve shall be inspected to
verify that all components operate properly. Internal
components shall be cleaned, repaired, or replaced as
necessary.
