Does anyone else have their answering machine hooked up to DC? I had been using a Radio Shack answering machine for 5 years, the wall wart says 9VDC and 12 volts DC seems close enough. It worked for years anyway.
After a lightning strike a few months back, that answering machine failed and I got another 9 VDC unit off of ebay, and another and another. The last 3 three worked OK for a couple days and then caused static on the phone line and when someone calls it gives a busy signal. They are all Radio Shack units, as I can find no other manufacturer who makes one in that voltage range.
About the same time I got the lightning strike, I converted my solar system to 24 VDC, it was a 12 VDC system up until then. For my answering machine, DSL modem and laptop I use a Samlex SDC12 24 to 12 VDC converter. The output reading is 13.5 VDC. Is something wrong with the Samlex causing them to fail?
I have a landline here so I called the phone company repairman and he came out here and said it was a bad answering machine.
I can't understand why 3 in a row could go bad so soon.
?
Is there an answering machine I can buy that will work directly on 12 or 24 VDC? 24 VDC would be perfect because I could bypass the Samlex.
