Recommended Monitoring Equipment
In-Line Corrosion Detectors
The In-Line Corrosion Detector (ILD) is designed to provide an early warning of corrosion activity within
the fire sprinkler system. The ILD features a double wall construction that incorporates a thin milled
section of pipe (.035” (8.9mm)) surrounded by a full thickness piece of pipe to detect and alert to the
presence of corrosion activity. If corrosion occurs the milled section of the ILD will fail prior to the failure
of any other section of the pipe wall. When the milled section fails it allows the system to pressurize the
chamber outside the milled section of pipe which activates the attached pressure switch on the ILD. The
pressure switch can be remotely monitored through a building monitoring system.
The ILD is placed at strategic locations within the fire sprinkler piping network where corrosion has the
highest potential of occurring.
• Wet Systems - Locate the ILD in high point of the sprinkler system, typically at the air/water
interface in a branch line, where air will be trapped as the system is filled with water.
• Dry Systems - Locate the ILD in a horizontal portion of the supply main piping where trapped water
will accumulate.
SMART Gas Analyzer
The SMART Gas Analyzer (SGA-1) provides continuous real-time nitrogen/oxygen concentration levels
within a dry pipe and preaction fire sprinkler system. The analyzer samples discharge gas from an adjacent
Standard Vent (PAV-D/DQ) or SMART Vent (PSV-D/DE). It is equipped with programmable outputs for one
of three different oxygen concentration levels (1%, 3%, and 5%), providing early warning to a user when
the nitrogen concentration within the fire sprinkler system falls below the desired level. The SGA-1 is
equipped with an analog (0-5VDC, 0-10VDC, or 4-20mA) output and an RS-485 port for optional remote
control and monitoring as well as displaying either oxygen or nitrogen concentration.
Handheld Gas Analyzer
The handheld gas analyzer (PHGA-1) allows for quick, convenient reading of nitrogen gas purity levels. The
gas analyzer can be connected to any of the sample ports on the ECS devices such as the nitrogen
generator or the vent. Additional sampling ports can be ordered and placed at any point on the systems
where gas purity monitoring is desired.
