Hi Every body.I have just registered and would like to ask a question please.

I have an excisting alarm.The alarm works fine, but the outside bell sounder does not operate when the alarm is activated.I have removed the bell,(which is very old and a circular bell inside the bell box).I would have just liked to replace the round bell, but it is proving quite difficult to replace with another round bell.There are only for wires into the bell box red and black to the bell and blue and yellow are tamper and go to a micro switch that is activated then the screw is removed from the bell box.

Could somebody please tell me as the wiring is so basic what type of bell box I could replace it with or where I can buy a round bell to go in the existing bell box. 

That type of bell hasn't been manufactured in many decades.

Replace for an SAB of your choosing you may find a model with the aesthetics your looking for.

If you need help with the wiring upload a picture of the panel end terminals and we can try and point you in the right direction.

Hi Global Moderator,

                                   Thank you for your answer.I was really just wondering if I could do a straight swap using the existing 4,wires.Is that possible.

Come on guys please give me some help on this, thank you.

I have explained the best way forward.

Replacing your bell would be a waste of time and energy even if you can find a like for like replacement.

+12v 

-0v

Bell is the trigger 

 

But your old panel needs to be seen to be sure how to connect it, assuming your panel output goes to zero or goes to 12v will depend on where you can connect a sounder to it 

 

You need the tamper blue and yellow that might be able to work across the zero volts and t connection but that's if you buy an up-to-date date bell 

 

Or just buy an electronic sounder to suit the power output and stick it the old box 

 

And then don't buy a new phone or service your car for a couple of years and save up to have a new alarm fitted or buy a new alarm to be fitted and come back here and get help how to replace it possibly

 

Make sense?

Hi Sorry if I addressed you by the wrong name.Why would replacing the bell be a waste of time.The alarm works perfectly fine.It is just the external bell does not ring when the alarm is activated.

The alarm works perfectly fine.It is just the outside bell does not sound when the alarm is activated.There are a red and a black going to the existing bell.And only the tamper loop wires to the micro switch.That is all the wires in the outside bell box. 

When was the alarm last serviced? Have you replaced the standby battery in the control panel recently?

It may seem to arm/disarm fine but without operational checks you may not know until it fails to operate.

You done anything I said then? Or ignored what anyone is writing?
