Summary DMC designed and implemented a system for performing automated testing of visual (strobe) and audible (alarm) signal appliances to ensure that these devices comply with UL and ANSI standards.

The audible alarm testing involved monitoring the sound output from multiple appliances to verify that the signals of multiple devices remain synchronized and that they match a specied temporal pulse pattern. Customer Benefits Automation: Automation: Executing tests (of any duration) is fully automated, requiring a single "Start Button" press to begin the testing process Flexibility: Flexibili
