I-751.Europe / European Alarm Check Valve Stations / Installation, Maintenance, and Testing Manual
REQUIRED MAIN DRAIN TEST
Refer to current, applicable local and national fire protection standards
to perform main drain tests. The authority having jurisdiction in the
area may require these tests on a more frequent basis. Verify these
requirements by contacting the authority having jurisdiction in the
affected area.
1. Notify the authority having jurisdiction, remote station alarm
monitors, and those in the affected area that the main drain test
will be performed.
2. Confirm that sufficient drainage is available.
3. Record the water supply pressure gauge (Item 5) and system
pressure gauge (Item 7) readings.
NOTICE
• Close the alarm line ball valve at this point to prevent alarms
from activating during the main drain test.
• FOR FG AND SBSC TRIM: Close the alarm line monitoring ball
valve(s) at this point to prevent alarms from activating during the
main drain test.
4.
To prevent alarms from activating during the main drain test, close
the alarm line ball valve (Item 13). FOR FG AND SBSC TRIM:
Close the alarm line monitoring ball valve(s) – Item 14a on page 7.
5. Open the system main drain valve (Item 9) fully. Record the water
supply pressure gauge (Item 5) reading as the residual pressure.
6. Close the system main drain valve (Item 9) slowly. Record the
water supply pressure gauge (Item 5) reading after closing the
system main drain valve.
7. Compare the residual pressure reading to the residual pressure
readings taken in previous main drain tests. If there is degradation
in the residual water supply reading, restore the proper water
supply pressure.
WARNING
• The alarm line ball valve or alarm line monitoring ball valve(s)
shall remain in the open position to allow alarms to activate.
Failure to follow this instruction will prevent alarms from activating,
resulting in death or serious personal injury and property damage.
