Records:
1. Records of inspections, tests, and maintenance of the
system and its components shall be maintained by the
owner and made available to the Authority Having
Jurisdiction upon request.
2. Records shall indicate the procedure performed (e.g.,
inspection, test, or maintenance), the organization that
performed the work, the results, and the date.
3. Original records shall be retained for the life of the
system.

acceptance test (if available) and with the most recent
test results.
The following requirements are based upon NFPA-25.
Monthly:
INSPECTION:
ICAF Discharge Nozzles:
ICAF discharge nozzles shall be inspected visually and
maintained to ensure that they are in place, continue to be
aimed or pointed in the direction intended in the system
design, and are free from external loading and corrosion.
Misaligned discharge nozzles shall be adjusted (aimed) by
visual means, and the discharge patterns shall be checked at
the next scheduled flow test.
Only ICAF discharge nozzles are approved and shall be used
with ICAF system. Inspection shall verify that unlisted
combinations of discharge nozzles have not been
substituted.
Control Valves:
The valve inspection shall verify that the valves are in the
following condition:
1. In the normal open or closed position
2. Properly sealed, locked, or supervised
3. Accessible
4. Provided with appropriate wrenches
5. Free from external leaks
Flow Control Valves:
Valve enclosure heating equipment for ICAF system subject
to freezing shall be inspected during cold weather for its
ability to maintain a minimum temperature of at least 4°C
(40°F).
The gauge on the supply side of the flow control valve shall
indicate that the normal supply water pressure is being
maintained.
The gauge monitoring the ICAF system air pressure shall be
inspected monthly to verify that it indicates that normal
pressure is being maintained.
The flow control valve shall be externally inspected to verify
the following:
1. The valve is free from physical damage.
2. All trim valves are in the appropriate open or closed
position.
3. The valve seat is not leaking.
4. Electrical components are in service.
Quarterly:
INSPECTION:
Drainage:
The area beneath and surrounding a ICAF system shall be
inspected to ensure that drainage facilities, such as trap
sumps and drainage trenches, are not blocked and retention
embankments or dikes are in good repair.
System Piping and Fittings:
System piping and fittings shall be inspected for the
following:
1. Mechanical damage (e.g., broken piping or cracked
fittings)
2. External conditions (e.g., missing or damaged paint or
coatings, rust, and corrosion)
3. Misalignment or trapped sections
4. Low point drains (automatic or manual)
5. Location and condition of rubber-gasketed fittings
Hangers and Supports:
Hangers and supports shall be inspected for the following
and repaired as necessary:
1. Condition (e.g., missing or damaged paint or coating,
rust, and corrosion)
2. Secure attachment to structural supports and piping
3. Damaged or missing hangers
TEST:
Water-Flow Alarm:
All water-flow alarms shall be tested in accordance with the
manufacturer’s instructions.
Semiannually:
TEST:
Supervisory Switches:
A distinctive signal shall indicate movement from the valve’s
normal position during either the first two revolutions of a
hand wheel or when the stem of the valve has moved one-
fifth of the distance from its normal position.
The signal shall not be restored at any valve position except
the normal position.
