AdvancedIQ Vent Controller (AVC)
The AdvancedIQ Vent Controller (AVC) provides automatic oxygen venting, monitoring of
nitrogen/oxygen concentration levels and monitoring of the sprinkler system pressure within each dry
pipe/preaction fire sprinkler system. As a fire sprinkler system is filled with a continuous supply of nitrogen
gas from the nitrogen generator system, the vent, installed on the sprinkler system riser, allow
oxygen-rich gas to be vented from the fire sprinkler system.
The AVC samples the discharge gas from each vent connected to the controller. Over a fourteen (14) day
period, the vent will dilute the oxygen concentration in the entire fire sprinkler system to less than 2%
oxygen. The gas flows out of the restricted orifice on the vent through pressure-rated tubing to provide
slow, controlled flow to the AdvancedIQ Controller. Once the desired system gas composition is reached,
the controller will automatically close and stop the venting process thereby preventing continuous
venting. The AVC is equipped with a programmable logic controller (PLC) and a human-machine interface
(HMI) with an LCD display to control the venting process and continuously monitor the nitrogen purity
levels in the sprinkler systems.
AdvancedIQ Vent Controller Features
The AdvancedIQ Vent Controller, in conjunction with oxygen removal vents along with the ECS patented
“fill and purge” breathing technology, includes the following features:
• All equipment is installed in the sprinkler riser room for easier installation and servicing
• Individual pressure & purity monitoring for up to six (6) sprinkler systems
• Datalogging & historical trends for each sprinkler system
• Leak rate checks for each sprinkler system
• Internet connectivity and remote monitoring capability
• Removeable datalog (flash drive)
• Form-C dry contact supervisory
