Hello All
I have interconnected hardwired smoke alarms and they used to got off when generator charging for no good reason.
Now they have decided to start going off while on inverter power, 2 Outback VFX3648's and an x240.
Voltage at time of alarm 119.6 and 59.9 Hz. That to me seems close enough.
Does anybody have any ideas before they get scraped? Filtering or some such that doesn't eat too much power, if that is possible.
Update: I looked at the voltage again and it was at 117.4, so I raised it to around 120 by upping the inverter output. It is sort of strange, I have never seen the inverter power off that much and it was only a few minutes between the 2 readings, with no real difference in Ac draw, around 1400. The sun is kicking today so I'm burning up some of that free stuff!
I know some of you have had some Outback experience!
Thanks
Wade
Has anything else changed in the location? Im one particular place we had a lot of trouble with optical ones. Seemed to be tripiing on water vapour from high condensation levels or something. I tried serval brands, and found that all did it before giving up and using ionising. There is little as annoying as being woken at 3am.
Hello Zoneblue
No nothing new, the alarms have been installed for over a year and only went off on generator until yesterday. I haven't changed an inverter setting in forever.
It went off yesterday when on inverter, exactly when the wife hit the microwave and maybe when a dehumidifier compressor kicked on later. Haven't had any repeats since I moved the voltage up. I have noticed that the Ac voltage is not totally stable with around a 3 volt variation, it may have always had that and I'm just watching too closely.
I don't believe there is any water vapor issue, 45% Rh.
Thanks for your thoughts
Wade
