FPS-900-RS does not have power, the production and storage of nitrogen will
become apparent once the storage pressure drops.
• Check the power cord.
• Has the building’s circuit breaker or GFCI tripped? Locate the breaker and reset. If
breaker continues to trip, the circuit may be overloaded.

FPS-900-RS will produce and store Nitrogen at 70 (+/-3) psig. Once the storage
tank reaches 70 (+/-3) psig, the system will go into Standby Mode. When the pressure drops by
about 7-10 psig, the system should go into Run Mode and begin to refill the storage tank. If the
system is out of specifications, the location of the issue must be identified. Then contact the
manufacturer or factory trained technician.
Nitrogen Pressure Check:
The pressure gauge on the front of the cabinet should be between 60-70 psig. If the pressure is
low, check the following:
• Check the power.
• Find out if fire protection system is being tested.
• Check for leaks throughout system.
Refer to section 8.2 Checking for Leaks.
11.3. Gas Leaks
As with any gas system, only use a spray bottle on non-electrical equipment to find leaks. Fix or
replace leaking fittings or hoses. Push-to-connect fittings will show bubbles and typically have up
to a 5ccm acceptable leakage rate. Contact your local provider / installer for help.
