Hey Les, I'm thinking that if you got a regular doorbell that operates on 1=
6/24 volts AC, that if you adjust the electrical coil contacts and the reco=
il spring on the doorbell it will probably work with 12 VDC. Might not be a=
s loud as with 16VAC but it's just a coil and a set of contacts.=20

Also, if you scraped some of the insulation off of the relay coils and sold=
ered/shorted out some of the windings it would work better at 12VDC.  And, =
how about using 24VDC? If your just closing a set of contracts to operate t=
he bell, use an Altronix 12/24 VDC power supply set at 24 volts.=20

If you're using the 12VDC from an alarm panel it's gonna use a lot of curre=
nt.
