Hi,
I am a commercial plumber in North Carolina.
I have invented a 9 volt, magnetic reed switch activated, two conductor, high wet well alarm system. It was simple for a non electronics minded person.
The alarm is 108 Decibels. It has a push to test battery switch, and works great!
I need to put a low battery warning chirp circuit in it, so that it chirps like a smoke detector when the battery gets low, and needs to be replaced.
I called all of the smoke detector companies and they will not give out this information. They said that it is properiority information.
Does anyone know how to make one, or where to purchase such a circuit for a 9 volt project?
I would really appreciate any info!
Thanks,
Mike
