Hi folks.
This isn't a homework question as I left school about 45 years ago, but I didn't want to bother the experts with trivia.
I have a doorbell that is a long way from the sounders, which means when people push the button they can't hear the sounders. This causes all sorts of problems.
What I want to do is fit a buzzer behind the bell push. (Very limited space)
I have taken my 240vac supply through a transformer to supply 18vac, then through a rectifier to give 18vdc. This runs two sounders through a solid state relay.
I purchased a dc buzzer to put behind the bell push but I can get it to buzz. I was hoping just putting it in series would have worked.
Thinking it may be voltage, I've tried dropping the voltage by using two resistors, but still no luck.
The resistors were 6k2 and 2k2. (Was thinking too big).
I used Vin X R1 / R1+R2 = Vout
I've checked the buzzer on a 6v battery and it's fine.
Can anyone help please?
