I am fairly confident that he is talking about the 16V1T-B because in my video of Union City's 16V1T-B, I mentioned in the desc I tried to go to the 16V1T-B in Blanchard but it didn't go off, and he commented on my video:

If it's dual tone with a battery pack, it's a 16V2T-B. All it is is a 15V2T with 8 HP DC motors in place of the 15 HP 3 phase or dual 7.5 HP single phase motors. All dual rotor Sentrys, 10V2T through 40V2T, can be single or dual tone. All they're doing is switching an 8 port chopper with a 16 port one, 10 for 15 in the case of the 40V.

The single phase 15V and 20Vs are a little taller than their 3 phase counterparts due to using 2 single phase motors as opposed to on single dual shaft motor. If it's tall and lacks the battery pack, it's a single phase 15/20V

I wouldn't be so sure its dual toned either. Those 16V1T-Bs have a pulsing harmonic/undertone from the two stators being controlled by separate motors (so one's ports might be [partially] shut while the others are [partially] open). It can sound dual toned when it really isn't.

It's a 16V2T-B. They wanted a new siren that sounded like their older Sterling M-10 with the battery backup. This is a video of it running on dying batteries.

16V2T-B? Never heard of that!

EDIT: That could be the 16V1T-B mixing with the other Sentry's in Blanchard's system.

Sentry will customize sirens for customers who want a siren from them, IIRC, so it's very likely it could be dual toned.

Ian M. confirmed that it was a 16V2T-B a few years ago.

It replaced an old dual toned Sterling M-10 a while back, so I guess they wanted to keep that old sound with a more modern, battery-powered siren. Sounds like those batteries are about done for though. On a side note, they also have a bunch of 7V8-Bs scattered around the outskirts of town.

I heard this siren wind up right next to me in a tornado warning. It's even heard in the corresponding video I posted on YouTube. Again...it's dual toned. There's really not much to speculate here, people.

Exactly. I know Dillon wouldn't say it if he didn't know it. I only wondered what to call it. This amount of speculation is a bit much.
