September 2013 4-58 P/N 81-CO2MAN-001
4-7.7 Full Discharge Test
A full discharge test shall be performed on all systems.
1. Notify all personnel in the protected area, and all areas where carbon dioxide can migrate,
of the impending carbon dioxide system discharge test.
2. Arm the system by first installing the control head(s) onto the pilot cylinder(s), connecting
the discharge heads to all cylinders, and then de-isolating the release outputs from the
control unit after ensuring that no alarm conditions exist in the system.
3. Operate any initiating device or combination of initiating devices (as appropriate) to
actuate the extinguishing system.
4. Check operation of the pneumatic siren, time delays, damper closures, and equipment shut
downs.
5. Verify that carbon dioxide is discharged from all nozzles in accordance with the design
requirements for local-application systems. Confirm that the carbon-dioxide extinguishing
concentration is attained and maintained for the required period of time for total-flooding
systems.
4-7.8 Commissioning the System
Upon successful completion of the system inspection and test procedure, the system shall be
commissioned in accordance with the following procedure.
• Successfully perform the discharge tests in accordance with the specifications and to the
approval of the authority having jurisdiction, as previously detailed.
• Verify and document the details of the discharge test(s) and personnel-training program.
Fire fighting techniques with Hand Hose Line Systems and/or portable extinguishers must
be part of this program.
• Recharge all discharged cylinders after checking the last hydrostatic test date and retesting
the cylinders per applicable Department of Transportation (DOT)/Transport Canada (TC)
procedures. Begin to arm the system by reconnecting the cylinder(s) to the mounting rack,
installing the control head(s) onto the pilot cylinder(s), and connecting the discharge heads
to all cylinders. Return all parts of the system to full service.
• Verify and document the details of the personnel-training program. Fire fighting techniques
with Hand-Held Hose Lines and/or portable extinguishers must be part of this program.
• De-isolate the release outputs from the control unit after confirming that no automatic or
manual initiating devices are in an alarm state. This will make the system operability
effective.
• Notify all appropriate authorities (owner, insurance underwriter(s), fire department, etc.)
in writing that the carbon dioxide fire protection system is now armed and fully operational.
6. Submit a Certificate of Commissioning to the Owner.
