I found a vintage alarm bell that was probably used in a school or fire house.
It's nameplate is clearly marked with "6 V", "DC Only".
I have powered it with a 6v AC/DC adapter and it works well.
I am trying to figure out the proper way to permanently connect this alarm bell as my doorbell.
I have a standard 24vac transformer currently powering the doorbell.
I could remove the transformer and use the AC adapter, but those aren't really designed for permanent installation.
I could hard wire a rectifier to it...but I just don't know what and if that would be considered to code.
I have seen 6vdc power supplies in enclosures made for alarm circuits, but that seems like overkill.
