UUKL Listing for smoke control applications!
Among several great enhancements to this industryleading line, V6 firmware unlocks support for smoke control features.
The PRTI is a UL listed indicator of trouble condition with Potter PFC-3000, 5000, and 9000 series fire alarm control panels. When a trouble condition occurs, the PRTI will sound the piezo and illuminate the amber LED. When the trouble is restored, the PRTI returns to a standby state automatically.
