Hi guys, having trouble with the tamper on my bell box. The five wires are connected in correctly and the jumpers are in the factory set position but there is a black small box which moves to the side it is about an inch long by half inch wide and seems to be connected to a couple of wires going into an inclosed bit. In its normal state it is slightly off centre and the alarm rings as soon as i put the battery into the control panel. I have then wedged it closed and the alarm stops ringing but i have the feeling that the alarm will not ring at all now.....doing all walk through tests now but what is this it seems like a tamper switch but do i need to wedge it closed and what impact is this having?
