The Honeywell IRIS Watchdog III system monitors pilot and flare stack activity using an ultraviolet sensor. It provides continuous burner surveillance indicating the presence or absence of a flame at the flame tip. The RP222A signal processor includes two independent relays, one for early response (adjustable from 1-60 seconds) to a flame loss, and the other for time-delayed response (adjustable between the early response time and 60 minutes) for a flame-out alarm. The signal processor can be AC or DC powered, and is designed for use with the Honeywell IRIS CS256 ultravoilet viewing head.
