April Fire Drill @ EHS 4/24/19

Drill starts at 0:19. First thing first, I have no clue why the 9252s are sounding that way. What I can tell you is that the alarms are very glitchy. About 3 years ago (2016), the alarm seen at the 0:49 mark used to have a different coding. Not only that, it was completely flipped upside down and didn't work (that issue was later reported). A year later, it was working properly which it was coded to do Code 3 and had a 9236 horn on it. Furthermore, after hearing them go off in 2016 I wanted to film them going off again using the 9236 horn. When I entered the area, not only it was doing Code 3 and March Time alternating it was using a 9252 horn and the strobe light wasn't flashing. There's also an alarm at the 1:20 mark which didn't have a working horn but had a working strobe. After reentering the building, I then shoot the scratchy sounding 9219. Which I have film more than twice. Alarms heard Simplex 4903-9217 Simplex 4903- 9219 Simplex 4903-9252 The strobes in the bathroom are Simplex 4904-9112 Next month is sadly the last time I will be making a fire drill video.

Something special might be happening to next month's drill. Update as of May 14th, we figure out that there may be an issue with the sync model in this particular zone. However, unsure if the problem has been resolved.
