EDIT: Two people beat me to it while I was writing this!
===============
Beats me. I keep listening to it and I can't figure it out.
*Its definitely electronic
*It doesn't fit the tone profile of a Whelen
*ASC is the only one making an "old style" attack tone now-a-days on their electronics, however, that isn't relevant as I'll show later.
*It doesn't have the classic soft start of an ASC electronic and it peaks too low for ASC's tone set.
*It also strikes me as having a similar tone profile as an older Mod, but it peaks WAY too low.
* It sounds, on the wind up, a lot like Moore's odd-ball Mod in terms of speed of wind-up (but peaking lower):

*The tone profile and the wind-down remind me of this Mod:

*Mods are highly programmable.
*Mods can be programmed to run a more standard attack cycle:

*Judging from the user's other videos, he is in or near Bucks County, PA. I tried Street Viewing the fire stations in that area to no avail.
I betchya its a Mod someone went in and tinkered with and totally screwed up. I just betchya. And watch as I'm wrong.
