Note:
When both dry pipe and preaction fire sprinkler systems are connected to one nitrogen generator,
additional equipment may be required if the fire sprinkler systems operate at different supervisory gas
pressures.
Step 4:
Plumb the Condensate Drain Line
The ECS Protector Nitrogen Generator will occasionally discharge a small amount of condensate water
from the coalescing filters inside the cabinet. It is recommended that the ¼
”
drain connection be
plumbed to a floor drain or building exterior. When plumbing to a drain is not feasible an evaporative
collection chamber can be used.
Step 5:
System Signals and Monitoring, where used
The nitrogen generator cabinet has two (2) system signals and five (5) outputs that can be monitored
by the facility
’
s BMS or fire alarm system.
•
The nitrogen generator is operating in the bypass mode which is activated when the bypass valve is
in the
“
fast fill
”
position to fast fill the fire sprinkler system and the air supplied directly from the
air compressor has reached a pressure of 20 psig (1.4 bar). (Flashing amber light)
•
The nitrogen generator is equipped with a leak monitor audible signal which is activated when the
nitrogen generator runs excessively. (Audible signal)
The nitrogen generator cabinet includes system monitoring signals which can be monitored through a
building monitoring system, if desired:
•
Nitrogen Generator Loss of Power (Form C contacts)
•
Bypass Mode Alarm (Form C contacts)
•
Nitrogen Generation Mode (Form C contacts)
•
Nitrogen System Supply Line Pressure (Analog Signal)
•
Leak Monitoring (Form C contacts)
