PREVENTIVE MAINTENANCE

Perform preventive maintenance per Table 1-1.
Schedule
Semi-Annually
4.1 Semi-Annual
Electric control heads (including electric/cable operated combination control heads) must be
tested semi-annually for proper operation. In addition, the Control Head Monitor must be
tested to ensure it is functional. These tests can be performed without discharging the
cylinders. Test one hazard area at a time completely before proceeding to the next, as follows:
All control heads and Control Head Monitors must be removed from the
cylinders before testing to prevent possible personal injury, death, or property
WARNING
damage in the event of accidental cylinder discharge.
1. Remove all electric control heads and Control Head Monitors from all cylinders serving the
hazard area being tested. Let the electric control heads and Control Head Monitors hang
freely from the flexible electric conduit connections. Leave all pressure operated control
heads, and pilot actuation hoses attached to the cylinders. Attach the safety cap to the
valve actuation port.
2. Check the control panel to see that the Control Head Monitor reports a supervision alarm
to the panel.
3. Operate the system electrically. This can be done by actuating the system at the system
control panel or from an electric pull station.
4. Ensure all electric control heads have operated, (that is, the indicator on the electric control
head has moved to the RELEASED position). If any control heads have not operated, check
the circuit for electric continuity to these particular heads and repeat the test. Replace all
damaged heads. Repeat the test if any control heads have been replaced.
Control head must be reset to the SET position (fully retracted actuation pin)
before reconnecting to a cylinder valve. Failure to follow this instruction will
CAUTION
result in cylinder discharge when attempting to install the control head.
5. Observe the instructions on the caution label attached to each electric control head. Re-
move the safety cap. Re-Install the Control Head Monitor between the control head and
corresponding valve. Re-attach all electric control heads to threaded port on cylinder valve
or pressure operated control head. Tighten the swivel nut securely. Make certain each elec-
tric control head is in the SET position before reconnecting to the cylinders. Failure to follow
this procedure will result in accidental discharge.
