hi could any one help me stop my inside sound bomb making a buzzing noise since i fitted a new oddysey bell box i have tried wireing it to strobe and also the bell but still the same or should i change the internal sounder for a different one any help appreciated baz== i think the interference is called harmonics or may be wrong it is a optima compact alarm thanks again

Take it off the external sounder circuit and the internal sounder circuit.
Put it on its own output.

What do you mean, own output?

Use a relay from the panel to switch the Sound Bomb.
Not the speaker drivers.

You don't run a soundbomb from the speaker drivers.

If you have spurious noises from your soundbomb you need to check your wiring.

It needs 2 connections. +12v and switched neg.

In it's dormant state it is only connected to the +12v so should make no noise as there is no 'circuit'.

 

[Alarm]

As I said keep it off the speaker drivers. ( As you mentioned the internal sounder, so covering all bases)

Yes Joe I know that, I was making sure the OP did, so thanks for your comment as UN-needed as it was.

In fact it is best practice to keep any sounder/speaker away from data lines as the induction can give the symptoms described.

thanks everyone for your input i will get a small relay to fire the sound bomb i have had this problem a few times when fitting a new bell box to old systems mostly on optima xm range panels thanks for your help again baz

I did say use a relay output from the panel, not a separate. But it wont hurt to use a free standing.
And keep it away from the data lines.
