Hi all,

 

I have a sound bomb and what I am trying to do is when the relay is powered on I want it to silence the sounder, I have tried but just cant get it to do it, Any ideas

 

Thanks for your help

Switch the positive feed into the sound bomb via the common and normally open

Negotiate straight from the supply .

Just run the power (either leg) through the common and normally closed connections of said relay

Oh silence the sounder ?

So it rings all the time ? And goes off when the relay in powered ?

Use common and normally closed for positive

Beat me to it James lol

i was thinking N/O and N/C from different people is bound to confuse the op lol

Lol

Yeah

Can't think of a reason for it having it in all the time tho . Or dropping the power to the relay to make it sound

Unless I've misread his post or

Annoying neighbors and a switch lol

for the help guys done it
