Section 5 Commissioning System
5 COMMISSIONING SYSTEM
Do not install the electric, pneumatic, or manual valve actuators until the system has been fully commissioned.
Failure to comply could result in personal injury or death from violent cylinder movement or over-exposure to
high concentrations of agent.
e system checkout procedures outlined in this chapter are intended to represent the minimum requirements
for the extinguishing system portion of the system. NFPA 2001 shall also be consulted. Additional procedures
may be required by the local authority having jurisdiction (AHJ).
e control system portion of the system providing automatic detection and release should be thoroughly
checked out according to the appropriate technical manual and the requirements of the local authority
having jurisdiction (AHJ) before completing this section.
5.1 System Review
Conduct a room integrity (door fan) test in accordance with NFPA 2001. e results of this test will provide
equivalent leakage area and, when conducted in accordance with the manufacturer’s instructions, will predict
the timeline for a descending interface to fall to a given height and estimate how long the extinguishing
concentration will be maintained in the protected room. Room dimensions identied in the course of this
test shall be veried to correspond with room volume utilized in determining Janus Design Suite® ow
calculations for the enclosure.
Check security and tightness of cylinder mounting brackets to a solid structure and cylinder bracket
straps.
Check and record cylinder pressure gauges and room temperature. Pressure should be 360 psig at 70°F
(24.8 bar at 21°C). For temperatures other than 70°F (21°C) refer to the pressure temperature chart in the
appendix.
Check the stamped ll weight on the cylinder nameplate to verify it is the correct amount for the room as
determined and documented in the design.
Piping should be checked for correct size, length, and grade and compared to the installation drawings,
Janus Design Suite® ow calculation results, and manual limitations.
Check pipe supports for proper type, mounting, and spacing.
Check that nozzle location, size, style, and drill diameters of orices match both installation/design drawings
and calculations.
