I-751.Europe / European Alarm Check Valve Stations / Installation, Maintenance, and Testing Manual
DAILY/WEEKLY INSPECTION
Refer to current, applicable local and national fire protection standards
to perform daily/weekly inspections. The authority having jurisdiction in
the area may require these inspections on a more frequent basis. Verify
these requirements by contacting the authority having jurisdiction in the
affected area.
1. During cold weather conditions, verify on a daily basis that the
enclosure temperature is maintained above 40° F/4° C.
2. Inspect the valve and trim for mechanical damage and corrosion.
Replace any damaged or corroded parts.
NOTICE
• If the alarm valve is equipped with a low-pressure alarm, monthly
inspections may be sufficient. Contact the local authority having
jurisdiction for specific requirements.
MONTHLY INSPECTION
Refer to current, applicable local and national fire protection standards
to perform monthly inspections. The authority having jurisdiction in the
area may require these inspections on a more frequent basis. Verify
these requirements by contacting the authority having jurisdiction in the
affected area.
1. Record the system pressure and water supply pressure. Confirm
that the water supply pressure is within the range of normal
pressures observed in the area. Significant loss of water supply
pressure could indicate an adverse condition in the water
supply. Any variations outside of the normal pressures shall be
investigated.
2. Inspect the valve and trim for mechanical damage and corrosion.
Replace any damaged or corroded parts.
3.
Confirm that the valve and trim are located in an area that is not
subject to freezing temperatures.
Restricted Orif ice/
Alarm Line Drain
(Item 10)
4. If the alarm valve is installed in a variable pressure system, confirm
that continuous leakage is not occurring from the restricted orifice/
alarm line drain (Item 10). NOTE: It is normal for intermittent
leakage to occur from the restricted orifice/alarm line drain due
to pressure surges that lift the clapper and allow water into the
intermediate chamber.
5.
Confirm that all valves are in their normal operating positions (refer
to the table below).
Valve Normal Operating Position
Alarm Line Ball Valve (Lockable) Open
Water Supply Main Control Valve Open
System Main Drain Valve Closed
System Test Valve Closed
Alarm Line Monitoring Ball Valve(s) -
FG and SBSC Trim Only
Open
ANNUAL INSPECTION
Refer to current, applicable local and national fire protection standards
to perform annual inspections. The authority having jurisdiction in the
area may require these inspections on a more frequent basis. Verify
these requirements by contacting the authority having jurisdiction in the
affected area.
1.
Perform the required main drain test in accordance with Section IV
of this manual.
2. Perform an internal inspection of the alarm check valve in
accordance with Section VI of this manual.
