Step 5: Internet Connection, where used
The nitrogen generator cabinet has ethernet cable connection to connect the nitrogen generator to the
internet through a local area network (LAN). Connect the ethernet cable from the LAN to the ethernet
connector in the nitrogen generator.
Step 6: System Signals and Monitoring, where used
The nitrogen generator cabinet has two (2) system signals and four (4) outputs that can be monitored by
the facility’s BMS or fire alarm system.
Two (2) system signals:
• Bypass Alarm - The nitrogen generator operating in the bypass mode which is activated when
the bypass valve is in the “fast fill” position to fill the fire sprinkler system and the air supplied
directly from the air compressor has reached a pressure of 20 psig (1.4 bar).
o Indication on HMI Display
• Common Audible Trouble - The nitrogen generator is equipped with a common trouble audible
signal which is programmable to activated upon a predetermined trouble.
o Audible signal
o Contact ECS for specific procedures to reconfigure common trouble signal
Four (4) system output signals for monitoring through a building monitoring system, if desired:
• Nitrogen Generator Running Mode - Form-C Contacts (Energized When Running, LED On)
• Bypass Mode Alarm - Form-C Contacts (Normally De-Energized, LED Off)
• Nitrogen Generator Loss of Power - Form-C Contacts (Normally Energized, LED On)
• Common Trouble - Form-C Contacts (Normally De-Energized, LED Off)
o Short Cycling - Runs more than ten (10) times per hour
o Excessive Runtime - Continuous running for more than four (4) hours
o Low Supply Line Pressure
o Bypass Mode - In Bypass for more than one (1) hour
o Filters Need Replacement
