Fire Alarm Test #24

Test of a Simplex 4100 ES voice system in walk-test. The speakers sound out the address of each device tested. Also the key switches on the walls are remote test switches for duct detectors/dampers. The switch makes it easier to test them without having to take them apart. On another note, I apologize for the delay in uploads as I accidentally had all my saved footage erased. Im working diligently to get new videos out to you guys so please bear with me. Thanks again
