Pyronix enforcer tamper on input

[Mrmagician]

Hi. I have had the system running for a few months. It's hard wired to a deltabell E. Input at panel is set to tamper and the bell has the 2k2 resistor wire from 0v to T. It's been fine all this time I've checked the siren lid and Microswitch rear screw their ok.
So now I've disabled input 33 it's ok at the moment. The question is is the bell box faulty or have I got to put a link in somewhere in the panel terminals or a resistor. Do I really need input 33 set to tamper?
Thanks

Could be a faulty tamper switch , did you adjust or even fit the back tamper adjust screw ?

Thank you for replying. I checked yesterday that the adjustment screw on the bell box was adjusted so to push the rear of the switch closed. Front cover snug.
Strange how it's decided to fault after two months. Cable is fine checked for breaks in the loft. As mentioned the wiring in panel has no links to adjacent terminals should their be?
Thanks

Zone 34 ? No

No zone 33 in panel set to tamper

Post picture ... the input is looking for 0v with the 2.2 k , so it's a single wire return ...
Tamper switch is probably cause

I will take your advice I will take it down either replace the microswitch or get a replacement Deltabell E. What would you do?
