Idk the answer to your 2nd question. But my last siren test I went to was a 2810. It works perfectly, and all the lights are off. Most of our sirens here are like that, but all of them work. If all the lights are off there are two possible conditions. #1 Low battery, if the pair of batteries drops ...
To my knowledge, 4000/vortex use limit switches to reverse the direction of the motor. In theory, maybe you could move the limit switches in the rotator assembly to choose how far the siren rotates. Just my thoughts. The Vortex has a continuously rotating rotor (just back and forth), the 4000 serie...
This is on a 2800 though. Why is the last light lit? I think the logic board's circuit for the rotor sensor is bypassed/jumpered on the omnis just so that it doesn't send back a false report of a "failure" for a nonexistent rotor during polling, but I'm not 100% sure on that. Makes sense ...
I counted four DTMF streams in the scanner audio. Probably multiple messages sent one over the top of the other. I hould try and decode that audio and see if I can extract them. Sounded like wail, Air Horn then Hi-LO.
Dang, that sounds like ---- Not very good. I came on board with Whelen in 2006, I don't have a lot of historical knowledge of these sirens, this could be some kind of bug or alternate tone issue. Never heard that kind of tone before. I am sharing this with our service guy to see if he has seen this ...
So it doesn't look like an octopus is stuck in the cabinet. They could have raised the cabinet up so it can be serviced from the back of a pickup bed. looks like the cabinet is sitting on the ground. Some small child could get tangled up and die in that mess. LOL
The DTMF signal I hear is that your monitoring rig or is that coming from the siren itself? Just Curious, normally the only time you would hear that from the siren is when the PA is engaged and disengaged.
