You need to connect the black and yellow coming from the bell to a 2K2 resistor. The other end of the 2K2 resistor goes into zone 1, then program zone 1 as tamper and label it as such with the description. Also, as the instructions say, your existing bell box (looks like a Gardtec/Risco XS3D) will use more power than the Enforcer is capable of supplying in alarm, so you should set the bell box to SCB mode (usually a jumper link to move over on the bell box PCB)
