Simplex Fire Alarm Test

This is a video captured at a small local grocery store stockroom. The owner had a bad horn/strobe unit that he himself replaced with this 4903-9425 unit from another system. You will see that the strobe does not sync correctly (it should flash at a rate of once per second.) You may be able to hear the panel chirping in the background. Since this system was installed in 1997, the signal coding is temporal code.
