Chevron Richmond Fire Siren Ambience

Sat Dec 02, 2017 3:49 am

This is to be one of the best sounding and scariest videos I've heard in ages.

Oh, this again! Still love that video to this day. That mix of an OM-120 and a Cyclone is just perfect. Am I right in thinking that the signal heard is the fire signal, as the timing is longer?

It maybe fire signal, but they're probably using it for danger. Its weird because I recorded an STH-10 and it kind of has the same timing, but not quite exactly the same as in the video.

Contra Costa County’s siren system uses a 12/8 second interval for emergencies and tests. These are not fire sirens.
