We bought the house about 4-5 years ago and have not had a problem
until now. The house is about 15 years old.
We have three smoke alarms seemingly wired together and powered by
120VAC. If there is a backup battery, I have no idea where it is. It
states that it is Model IL-930 from Ten-Tek Electronics. the
connector has three contacts on the back. When one beeps they all
beep. One is still connected and it does not beep, so I don't believe
it is a bad battery, if one exists.
I tried and failed to find any info on the web to get replacements.
I'm not sure I want to if there is no battery backup for when the
power goes out.
Would I just be better off replacing all of them with battery only
models?
