The second bell box has been entirely repeated as above, so there is 2 wires in each terminal in the control panel..
Which is exactly what i said NOT to do
breezer said:If you were to wire them all in paralel each sounder would provide a return to say everything is ok, so in order to create a tamper you would have to remove both sounders
The drawing i have made shows how it should be done, some will call ther terminals by other names.
However some sounders' tamper returns have a current liniting resistor (no idea why) if this is the case You will need to install a relay on the return from the front siren so that this will break the supply to the Neg to the rear siren
