I was virtually outdoor warning siren hunting when my street veiw landed facing the (I Think) kidde fire alarm. Feel free to find your finds here.
Fire Alarm Find
That’s a Potter/Amseco SH-1224WP-W weatherproof horn/strobe, in this case being used as a sprinkler alarm, though oddly enough it’s the white model while the plate behind it is red (since from what I’ve seen the red version usually comes with the plate instead). I believe Potter only stopped manufacturing this particular alarm fairly recently supposedly due to a part for it no longer being made.
At a bank in my town I found a Wheelock 7002t horn only outside on a sprinkler alarm mounting plate
I don’t think it works though.

Turn to your right and look at the side of the bank
38°29’22"N 107°53’18"W
If you look at the side of the red shield thrift store
When you point at the traffic light look off to your right
I think that there’s either a system sensor mass
Or a Gentex SHG or GOS
