Awesome! Always wanted to know what those Amseco/Potter units sounded like. I figured they’d have the GX-90 - style sound. If I’m not mistaken, you’re the only one of us that has that particular model.
I miss the PA400 style mini-horns. I’m sad System Sensor discontinued them. They just had that unique look and they sounded more like a traditional smoke detector in the 4/6(?) pattern. But anyways, good videos!
They do have a sound similar to the GX90 but it is a little bit lower pitched. Man these things SCREAM. Imagine a smoke detector on continuous and about 2-3 times as loud. And wow! I figured they would be pretty popular! I got a ton of these, GX93’s PA400r’s and others all for a dollar and free shipping on eBay
I still have three or four PA400s, three white and one red. they’re a great choice for a low-current security system sounder. One is still installed in my hallway ceiling, but the wiring was abandoned at my Vista-20P panel when I added the Wave2 siren.
