We've just built an off-grid retirement home and are having problems with
smoke alarms that are required by local building codes. Three out of seven
of them 'chirp'. They are interconnected and mains powered with individual
battery backups on each one. We've replaced all their backup batteries and
they still chirp. I doubt that we have almost half of them bad right out of
the box.
Our inverter, etc is a brand new powercenter DR2424 from Trace/Xantrex. It
runs lights just fine. As almost any inverter would. We don't have any
other loads on the system. All appliances are propane so we don't mind the
minor constant draw of the smoke alarms.
No, I haven't tested the voltage and frequency the inverter puts out.
Simple answer is that I don't have the meters to do so.
Do smoke alarms need sign-wave power?
Do smoke alarms need EXACT voltage.
Do smoke alarms need EXACT frequency.
Suggestions?
Thanks,
Don
