Fire
Sprinkler System Quarterly Test
Information
on this sample form covers the minimum requirement of NFPA 25-1995
for fire sprinkler systems connected to distribution systems without
suppplemental tanks or fire pumps. Separate forms are available
to inspect, test and maintain fire pumps and water tanks. Additional
forms are also available for standpipe and hose systems, private
fire service mains, water spray fixed systems and foam-water sprinkler
systems. More frequent inspection, testing, and maintenance may
be necessary depending on the conditions of the occupancy and the
water supply.
PART
I - OWNERS SECTION
A.
Is the building occupied?
B.
Has the occupancy classification and hazard of contents remained
the same since the last inspection?
C. Are
all fire protection systems in service?
D. Has the system remained in service without modification since
the last inspection?
E. Was the system free of actuations of devices or alarms since
the last inspection?
PART
II - INSPECTORS SECTION
A.
INSPECTIONS
-
Daily, or weekly if low temperature alarms are installed
Enclosures around dry-pipe, preaction or deluge valves maintaining
a minimum of 40°F?
-
Weekly Inspection Item
Relief port on reduced pressure backflow prevention assemblies
free of continuous discharge?
-
Weekly Inspection Items which can be performed monthly if the
items are electrically supervised or secured with locks
A. Gauges on dry, preaction and deluge systems in good condition
and showing normal air and water pressure?
B. Control valves and isolation valves on backflow prevention
devices:
1. In correct (open or closed) position?
2. Sealed, locked or supervised and accessible?
-
Monthly Inspection Items
A. Preaction and Deluge Valves:
1. Free from physical damage?
2. Trim valves in appropriate (open or closed) position and no
leakage from valve seat?
3. Electrical components in service?
B. Dry-Pipe Valves:
1. Free from physical damage?
2. Trim valves in appropriate (open or closed) position?
3. No leakage from intermediate chamber ?
C. Sprinkler wrench with spare sprinklers?
D. Gauges on wet-pipe system in good condition and showing normal
water supply pressure?
E. Alarm Valves:
1. Gauges show normal supply water pressure?
2. Free from physical damage?
3. Valves in correct (open or closed) position?
4. No leakage from retarding chamber or drains?
- Quarterly
Inspection Items
A.
Sprinkler Pressure Regulating Control Valves:
1.
In open position and not leaking?
2.
Maintaining downstream pressure per design criteria?
3.
In good condition with handwheels not broken?
B.
Fire Department Connections:
1.
Visible and accessible?
2.
Couplings and swivels not damaged and rotate smoothly?
3.
Plugs or caps in place and undamaged?
4.
Gaskets in place and in good condition?
5.
Identification sign(s) in place?
6.
Check valve is not leaking?
7.
Automatic drain valve in place and operating properly?
(Note: If plugs or caps are not in place, inspect the interior
for obstructions and verify that the valve clapper is operational
over its full range.)
C. Alarm devices free from physical damage?
D.
Hydraulic nameplate, if provided, securely attached to riser and
legible?
B.
TESTING
The
following tests are to be performed at the noted intervals. Report
any failures on Part III of this form.
-
Quarterly Tests
A.
Sprinkler system main drain test:
1. Record Static Pressure psi and Residual pressure psi. Was flow
observed?
2.
Are results comparable to previous test?
B.
Waterflow alarm devices passed tests?
1.
Inspectors test connection opened? (Wet-pipe when not in freezing
weather)
2.
Bypass connection opened? (wet-pipe systems in freezing weather,
dry pipe, preaction, or deluge)
3.
Alarms actuated and flow observed?
C.
Control Valves (except OS&Y and gear-operated indicating butterfly
valves) opened until spring or torsion is felt in the rod, then
closed back one-quarter turn?
D.
Dry-pipe and preaction systems:
1.
Priming water level correct?
2.
Low air pressure signal passed test?
E.
Quick opening devices passed test?
F.
Valve supervisory switches indicate movement?
C. Maintenance:
-
Regular Maintenance Items:
A.
If sprinklers have been replaced, were they proper replacements?
B.
Air leaks in dry-pipe system resulting in air pressure loss more
than 10 psi/week repaired?
C.
Dry-pipe systems being maintained in dry condition?
D.
If any of the following were discovered, was an obstruction investigation
conducted and the system flushed?
Explain
reason(s) and obstruction investigation findings in Part III
1. Defective intake screen for pumps taking suction from open
sources.
2. Obstructive material discharged during waterflow tests.
3. Foreign materials found in dry-pipe valves, check valves or pumps.
4. Heavy discoloration of water during drain test or plugging of
inspectors test connection.
5. Plugging of sprinklers found during activation or alteration.
6. Plugging found in piping dismantled during alterations.
7. Failure to flush yard piping or surrounding public mains following
new installation or repairs.
8. Record of broken mains in the vicinity.
9. Abnormally frequent false-tripping of dry-pipe valves.
10. System is returned to service after an extended period out of
service greater than one year.
11. There is reason to believe the system contains sodium silicate
or its derivatives.
Part
III - Comments (Any No answers, test failures
or other problems found with the sprinkler system must be explained).
