Changing ADT (Elmdene) bell box on Galaxy 60

[JonSdl]

Hi all,

I have a Galaxy 60 with an ADT bell box that was presumed faulty as it would not trigger on an alarm state.  I purchased another ADT box which is a newer model.

 

When swapped over the new bell box will not stop ringing.

 

Connections are:-

 

H+ to 12v
H- to 0v

TS to H-

TR to T

R- to Bell

 

I have tried cutting/replacing the coloured links for 0 ohm and 1k but fault is the same.

 

Bell terminal is putting out 7v with 0v in alarm state.

 

Voice dialler is also working fine.

 

The panel gives 1004 Aux Tamp error.

 

(Battery and H+ were connected when testing)

 

Any help is much appreciated.  Thank you.

Those connections are in the galaxy 60? So assuming your tamper circuit is always open?

I think your link is correct black intact and the others are cut 

 

So has to be a switching issue or incorrect tamper wiring 

 

 

Or your bell trigger is incorrect

 

What happens if you disconnect the bell trigger and close it all up , does it stop ringing ?

looks likea grade 3 bell so will need a + voltage resistor on the bell trigger.

id suggest pulling the bell trigger upto 12v + (with bell trig disconnected obviously) and doing as all says and see if it stops.

The tamper return is another issue

Are all the coloured links cut?

Id just put a grade 2 bell on the non graded panel
