UUKL Listing for smoke control applications!
Among several great enhancements to this industryleading line, V6 firmware unlocks support for smoke control features.
The air maintenance device is used to control the supervisory air pressure in a dry pipe sprinkler system (and similar type systems). Additionally, it is used in applications that have a nitrogen source at a higher pressure than the desired system pressure. The integrated regulator maintains a constant pressure. The metering orifice limits the volume of air introduced into the sprinkler piping to assure that the rate of air replacement is less than that from a discharging sprinkler so that system activation may take place.
