Interesting / Unusual Alarm System Vids

Not something you commonly see - an EST3 system with Wheelock E50 speaker/strobes.

Some people might call this a Mickey Mouse operation…

If you’ve ever been to Walt Disney World, you may have noticed orange strobes (SAE IAV-series) in many attraction buildings, usually found near near the entrance and loading areas.
In these attractions, if a smoke detector activates, it causes a silent alarm where those orange strobes flash. After a few minutes, the main signals activate (at 1:38 in the video below.) If a second smoke detector activates, the main signals activate immediately.
The sequence is only for smoke detectors - if the alarm is activated in any other way (e.g. a manual pull station), the main signals activate immediately.
In all other buildings (e.g. standalone shops/restaurants, resorts, etc…), there are no orange strobes, and any activation causes the main signals to sound immediately.

So, here’s the video:

I didn’t know this chime existed until I saw this video.

I wanna say I’ve seen that chime somewhere before, but I can’t seem to remember.

It honestly doesn’t sound like a mechanical chime though, even though it is.

Note: The video is sped up. Set the playback speed (in the gear menu) to 0.75 to watch correctly.
So… this is at Disneyland’s Grand Californian Hotel.
This Simplex system has a trilingual custom message, in English, Spanish, and Japanese.
The English part sounds like it’s voiced by Bill Rogers, who voiced many things at Disneyland. (There’s a few different people with that name. It’s this one.)
It says: “Ladies and gentlemen, I am a fire team officer. Please walk to the the stairwells and proceed to the ground floor. The elevators are shut off. I repeat, the elevators are shut off. Please use the stairwells. Please close your guest room door as you exit.” (that last sentence confuses me a little - isn’t that what a door closer is for?)

How or why that’s the case I don’t get: it should have been filmed & uploaded at normal speed, no?

Quite an interesting system indeed. Wonder if Disney decided to add a Japanese message to the already-sometimes-standard English/Spanish bilingual message configuration due to Disneyland having a lot of Japanese-speaking guests.

Not all doors in a building likely have door holders: they probably put that line in there just to help make sure that as many doors are closed as possible to help stop/control the spread of smoke, fire, & noxious gases throughout the building.
