well obviously you have a tamper fault very irritating when 1 day you have tamper and the next you dont well id open the panel (the alarm will go off so enter your code)and look for tamp possibly green and white might be going into the two terminals in tamp or diffrent coulours either way unscreww the wires and cut a bit of the wire you just pulled out and loop tamp and see if theres any diffrence well first replace the lid and it should bleep and return back to day if it dosent try reset
if still nothing open the panel again and yes it will go off look for scb on the panel loop that aswell like you did to tamp and now the alarm should be working just remember to always press reset after the alarm has gone off and you will have to press reset this time aswell aftyer you replace the lid
let me know how it goes
