• Tested all area and master alarm functions.

• Inspected proper pressure switch and area alarm sensor locations.

• Tested Nitrous Oxide system for allowable gas concentrations of>99% nitrous oxide.

• Tested Nitrous Oxide system for particulate contamination in at least 25% of zones.
Tested with 0.45 micron filter device

• Tested Nitrous Oxide system for operational pressures of 50-55 psi at each zone.

• Tested each Nitrous Oxide outlet for proper function, identification, adaption and   
   mechanical integrity.
Identified leaking/malfunctioning outlets
Identified outlets delivering substandard pressure/flow rate

• Tested Nitrous Oxide zone shut-off valves for proper function, identification and   
   mechanical integrity.
