Victaulic 751 FireLock Series User Manual

REQUIRED SYSTEM TESTS
WARNING
• The building owner or their representative is responsible for
maintaining the fire protection system in proper operating
condition.
• To ensure proper system operation, valves must be inspected
in accordance with current national standards or in accordance
with the requirements of the local authority having jurisdiction
(whichever is more stringent). Always refer to the instructions in
this manual for additional inspection and testing requirements.
• The frequency of inspections must be increased in the presence
of contaminated water supplies, corrosive/scaling water supplies,
and corrosive atmospheres.
• Depressurize and drain the piping system before attempting to
install, remove, adjust, or maintain any Victaulic products.
Failure to follow these instructions could cause system failure,
resulting in death, serious personal injury, and property damage.
NOTICE
• Any activities that require taking the valve out of service may
eliminate the fire protection provided.
• Consideration of a fire patrol should be given for the affected
areas.
• Before servicing or testing the system, notify the authority
having jurisdiction.
MAIN DRAIN TEST
Perform the main drain test annually or as required by national stan-
dards. 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 moni-
tors, and anyone in the affected area that the main drain test will
be performed.
2. Confirm that sufficient drainage is available.
3. Record the system pressure (14) and water supply pressure (5).
NOTICE
• If you do not want alarms to activate, close the alarm line ball
valve.
4. Close the alarm line ball valve (11).
5. Open the system main drain valve (8) fully.
6. While the system main drain valve (8) is fully open, record the
water supply pressure (5) as the residual pressure.
7. Close the system main drain valve (8) slowly.
8. Record the water supply pressure (5) established after closing the
system main drain valve (8).
9. Compare the residual pressure reading, taken above, to the resid-
ual pressure readings taken in previous main drain tests. If there
is degradation in the residual water supply reading, restore the
proper water supply pressure.
