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)

Nah no need for contracts all IT is is turning it off and back on again.

The reed is just little bit of metal in glass tube.... I reckon most of the branded alarm contact manufactures buy in the same Reeds... The gases escapes for the glass tube & they either FA or just fail (open or closed) I suspect those the fail early have been thrown around or the screws knocked in with a hammer when fitted IIRC 13mm operating gap, thats look way too far apart
