You're right I didn't give a good discription. Let me try again
I have a twelve volt power supply that is hooked up to a power strip
which is driven by a timer accumulator. When the timer runs out the
power strip goes dead turning off the power supply and a couple of
other things. The twelve volt power supply on the power strip is
hooked up to a relay that it switches on and off or... from one relay
to another.
On one side of the relay I have another power supply that has a "in
use" and a "vacant" light hooked up to one side. When the power strip
goes on the relay is switched and the "in use" light goes on, when the
power goes off the "vacant" light goes on.
If you need to know, its for an adult oriented business.
this is the relay
1 and 2 twelve volt switcher
1-positve 2-negative
3-positive side of power supply 4-bell?
5-in use light 6-bell
7-vacant light 7-bell
Using the side with the bell hooked up I can either have the bell go
off when the circut is opened or closed.
A couple of problems with the door bell is that electro mechanical ones
burn out the magnet from being held on, with an electronic one if the
bell is held on for a while it rings off and on. Bells are also made
very cheaply and the ones that don't ring when held "on" just crap out
over time too.
I'm going to look into the part number you gave me, thanks.
