Every pack has a motion sensor on it. If you don’t move, it starts to make an irritating sound. If you don’t then move, the sound gets louder. If you don’t then move it gets really really loud. This is so that if a firefighter goes down, you can find them by listening.

When yours goes off, you just wiggle a little & it shuts up. If you don’t realize that it’s your pack that’s making the noise, you soon will, because your buddies will start smacking your helmet & saying “it’s you! Shake your ass!” I’m not aware of any other telemetry, but I’m sure that other departments, especially big city departments, have fancier stuff. We also use regular radio communication so Command knows how things are going on the interior. jrs > On Dec 31, 2014, at 7:34 AM, Dave Long <[email protected]> wrote: > > accelerometer telemetry which can be used to determine "man down" situations. > never took the contract, but I was once asked to study regularity in the > heartbeat interval to determine the effect in recovery situations, and these > units also provide all the necessary raw data for that. do you all use > similar systems, or would they be technological overkill?
