SECTION IX
UL EX-4510 12-1-01 Page 9-1
Inspection is a “quick check” that a system is operable. It is
intended to give reasonable assurance that the system is
fully charged and will operate. This is done by seeing that
the system has not been tampered with and there is no
obvious physical damage, or condition, to prevent opera-
tion. The value of an inspection lies in the frequency, and
thoroughness, with which it is conducted. Systems should
be inspected at regular monthly intervals, or at more fre-
quent intervals when circumstances require.
The following visual checks should be performed during an
INERGEN system inspection:
–Visually inspect the hazard area to verify that it has not
changed. Look for different fuels, new equipment,
blocked open doors or dampers.
– Check detectors to make certain they are in place, not
damaged or coated with dirt, grease, paint, or any conta-
minating substance.
– Check all manual pull stations to assure they have not
been tampered with and are not blocked from use.
– Check all alarm devices for damage, dirt, corrosion, etc.
– Check that the piping is secure and nozzles are in place.
Make certain the nozzles are not covered with dirt,
grease, or paint and that there is nothing structural block-
ing the discharge.
–Visually inspect all components for signs of damage,
such as disconnected or loose parts, corrosion, twisted or
dented components, etc.
– Check each INERGEN cylinder indicator (gauge) to
determine that the cylinder pressure is in the operable
range.
–Verify that all pressure switches are in place and are in
the correct, nonoperated, position.
–Visually verify that control panel and/or releasing device
is functioning properly.
– Perform any other checks that may be required by the
authority having jurisdiction.
–Verify that the pressure reducer/union contains an orifice
plate by visually noting the presence of the orifice indica-
tor tab on the side of the union.
– If applicable, push green poppet valve near solenoid on
selector valve to relieve any pressure.
–Visually check solenoid or electric actuator wiring on
selector valve to make certain it has not been disconnect-
ed.
– Make certain lever actuator on selector valve is in “SET”
position.
– Record that the system has been inspected and inform
the proper personnel.
