I installed a 12V DC megaphone style siren in my attic and am using a GE Outdoor Smart Switch to activate when my alarm goes off, but I’ve run into an unexpected problem: the GE switch provides a constant 3.5-4V through the outlet, which apparently is just enough voltage to I guess charge up the brick to give a quick “pop” or “chirp” sound every 20-30 seconds.
Can anyone think of a way to solve this?
