A few more examples:
My Faraday Type 512 horn is the new heavyweight champion. Hearing protection is a must with the thing because it’s easily over 100 decibels. If I thought fire drills with -9838’s were scary as a kid, I can’t imagine what it would be like with large vibratory horns, resonating horns - or the poor Oregonians who have Federal Model A and B-9 sirens…
I never thought about this before, but the famous agent-release Exceder at Tunxis Community College (set to high volume) was able to penetrate through:
- The brick wall separating the 600 and 300 wings, with closed fire doors
- The walls and doors of my dad’s office
- The pair of headphones I was wearing
Were it not for that “little Exceder that could”, my most popular video would likely have never gotten made.
A couple of honorable mentions:
-
The exit from the gym at Linden Street School was a very narrow corridor that had a 2903-9101 + 2901-9838 combo. A nice, healthy one, too

At Sedgwick Middle School, the gym had a 2901-9806 on a (burnt-out) 4050-90. It wasn’t painful since the gym was gigantic, but it was certainly awe-inspiring how loud a single horn could be. The outdoor alarms were also -9806’s, which were somewhat sickly but still carried far.
