Ronan manufactured the first solid-state integrated circuit-type annunciator on the market, assuring virtually unlimited system life. 

Annunciators can be found in control rooms, boiler rooms, power substations or any type of process or operational environment where conditions need to be personally monitored and status indication is necessary. 

There are integrated logic alarm annunciators whereby responsive operator actions are dictated by a programmed logic sequence and the LED lamp boxes which only offers an alarm display that will provide a visual status without logic. 

Continuous research and development has led to Ronan also providing solutions for Leak Detection as well as Signal Conditioning.
