I am a new member and I was hoping someone may have some experience with my problem. Reading the installation guide for Kidde 120 volt smoke detectors I discovered a warning that their detectors cannot be used with square wave or modified square wave inverters. These inverters are popular on solar photovoltaic systems and I have a number of these supplimentary power systems installed in homes.

I have since contacted Firex and BRK about this issue. Firex was unable to tell me if it was safe but initiated testing of thier devices and will contact me in a month or two with the results. A BRK engineer is suppose to contact me.
I have yet to contact any manufacturers of low voltage systems.

So if anyone out there has any inromation I would appreciate it.
