4-7.5 Labeling
1. Verify the labeling of devices for proper designations and instructions.
2. Compare the nameplate data on the carbon dioxide cylinders with the system
specifications.
3. Check the hydrostatic test date stamped on the cylinder(s).
4-7.6 Operational Tests of the Individual Components
1. Conduct nondestructive, operational tests on all devices necessary for functioning of the
system, including detection and actuating devices.
Note: Some system components, such as the (pressure operated switches,) may only be
tested during the full system discharge. Verification that all interlock functions properly
operate such as, damper closure, equipment power supply shut down, etc. is required
and must be documented.
2. Notify all appropriate authorities (owner, fire department, insurance underwriter, etc.)
when the carbon dioxide fire protection system will be tested, in accordance with the
approved schedule of work.
3. De-isolate the outputs from the control unit and assure that the carbon dioxide cylinders
remain disconnected from their associated discharge heads.
4. Operate all initiating devices such as heat detectors, smoke detectors and manual releases,
and verify proper receipt of all alarm initiating signals at the control unit.
5. Ensure that all control unit outputs (including the control heads) activate according to the
approved sequence of operations.
6. If any required function fails to occur, have it repaired, modified, or reprogrammed.
7. Reset the control heads after each activation.
8. Repeat steps 4 through 7 until all operating devices have been tested and the approved
operating sequence has been confirmed.
9. Verify the operability of all pre-discharge notification appliances and discharge time delay
devices.
10. For all occupiable enclosures, verify that the following safety features have been installed
and operate properly (where applicable):
a. Signage (per Standard NFPA 12)
b. Pneumatic pre-discharge alarm*
c. Pneumatic Discharge delay*
d. Odor additive* to the carbon dioxide discharge, or carbon dioxide detector, or
establishment and enforcement of confined space entry procedures.
Note: The operation of all pneumatic devices will be verified during the full system discharge
test.
11. Operate the electrical output from the control unit to the electrical control heads, ensuring
that the actuation pin is released.
12. Verify Check that all electrical signaling devices operate.
13. Verify Check that all auxiliary equipment responds as specified.
14. Verify Check pressure operated control heads manually during the full discharge test.
15. Test the control panel and its circuitry to assure compliance with NFPA 72.
16. Verify that all control panel circuits are electrically supervised for open circuit, short circuit,
and ground fault conditions to within 3 feet (.9 m) of any equipment being controlled, such
as air-handler shutdown.
17. Re-isolate the release outputs from the control unit.
18. Reset the electrical control heads.
