Is anyone able to identify this (maybe) alarm? There are several scattered around our new house and someone suggested they might have something to do with unattended children at the pool but even our alarm guy doesn't recognize them. Thanx.
Looks like some sort of "in an electrical box" alarm sounder.
If you have house doors that open directly into the pool area, many codes require the to be alarmed.
Can you post a pic of what's behind the coverplate?
