Starting with Relay Alarm Systems (annunciators), Ronan made the obvious technological progression by manufacturing the first solid-state integrated circuit type annunciator on the market, assuring virtually unlimited system life. In keeping with rapidly changing electronic component development, Ronan was first to introduce a stand-alone microprocessor controlled annunciator, enhancing reliability, mechanical packaging density, and ease of operation. Continuous research and development has kept Ronan's product line the most advanced in the industry.
