I came across this video on YouTube. Does anyone know what’s going on here?

It appears the fire alarm is going off!

I think they were doing a test at that time, although it’s quite rare to hear the Simplex 4100U whoop sound in short code 3 tones.

Do you know how they get it to do code 3?

First time I’ve seen a Simplex system have the code 3 whoops but it’s possible to have it be a custom edit of the existing tone.

I really like that code 3 woop

7

As far as I can tell it’s just a voice-capable Simplex system that just so happens to have a unique temporal whoop tone (never heard another one like it actually).

8

Speaker output through a coding relay, perhaps?

9

Probably an AHJ requring Code 3 in a whoop pattern, or on-site choice. Whatever it is, I love this tone!

Another exampleThis sounds exactly like a Simplex slow whoop forced into code 3

11

That’s actually the temporal whoop tone that a Simplex 4003 voice panel makes.

Newageserveralarm did a video showing all of the 4003 tones and messages and a code 3 whoop was one of them.

Yep: that’s one place I’ve heard it, along with the video fireburner posted.
