Hi, I’ve had my 2GIG panel up and running flawlessly since November 2014. Not a single problem. I have had an ATW “The Bloodhound” external siren hard-wired to the panel.
It was one of the few sirens that would draw less than 120mA. It has been working perfectly all this time, but this week it started to click continuously. The siren still works when the alarm is activated, but the rest of the time it’s making this light, clicking noise. I assumed it was the siren, so I bought and installed a new one, but it is also making the exact same noise.
