Milestones in alarm annunciator technology

Unitro has been building fault alarm systems under the mission statement the power to control for use worldwide for nearly 50 years, to provide efficient monitoring of care and operating facilities.

The WA16 and WA40 Windows Alarm Annunciators are the new generation of intelligent cyber-physical ICT systems, primarily for use as fault alarm systems at electrical substations as well as HMI systems for condition and facility monitoring in industrial applications, building services, and the municipal sector. Functionality, robustness, and longevity of the products, as well as a competent, innovative implementation of customer requirements, are archived through our own development
