Ex-Waukesha ACA Alertronic AL-4000 - All Signals - SirenCon 2024 

Man Tom did a nice job on refurbishing it, also I’m glad I was able to see it 3 times in the wild (even though it was long inactive)

This was extremely underrated, my favorite siren of the entire event

im glad someone saved that siren i remember seeing it in person on a building inactive

I love the tones at 2:11 and 2:35, really interesting. It's like a continuous, rapid yeow/yelp tone

A neat siren.

That is awesome.I was at sirencon at that time

This is out of order but here are the names of each signal Alert - duh Attack - duh Hi Lo - duh Air Horn - pulse (2 on 2 off) Fire - slow attack Chime - slow low-pitched chime Hazard - whoop with the short gap Scream - whoop with the sharp wind down Wail - scream but reversed (and lower pitch for some reason) Silent test - 12,500hz tone for 3 seconds (not tested)

The tones at 2:11 and 2:35 are a yeow and the Scream tone ASC used to have their tones listed on their old website.

1:13 doesn’t sound quite right for a siren, but it sounds pretty cool. I don’t know whether it’s just me or possibly the way the sound was picked up by the camera but when I hear it, it sounds like it’s hitting each of its oscillating tones separately instead of going in one fluid cycle, as it’s winding down.

Is this Alertronic from 1990?

we had House mode Elevator Mode Dented Camry Car Alarm mode
