When I install it, where it is supposed to be, it goes into this tamper alarm mode and it does not help to remove and then add the device or removing the battery, keeps staying in the tamper alarm mode. Have ran out of ideas. Any suggestions on what to do about it???

It is only one contact and it enrols fine and I also suspect its something with the tamper switch, but have not figured out how to reset the switch. Thought it was enough to put back the cover but apparently there is something else that needs to be done.

 

Could you please explain how to 'reset' the tamper switch after it has been violated?

I think the panel is reporting a "tamper alarm" msg, this can be cleared by simply arming and disarming the system after you has pressed "OK" to read the msgs

outstanding on the panel.

 

Hopefully this helps.

 

 

Have tried to acknowledge the alarm at the panel but does not help, still says tamper alarm and the unit is in 'not ready' mode. Any other ideas?

I'm guessing the fault is actually "Tamper Open" as opposed to "Tamper Alarm".

If that is the issue then you have either not closed the unit correctly or have somehow distorted/damaged the board on the MC-302E and that's causing a tamper fault.

The system won't ARM unless the tamper is reset by either the lid closing or the board being re-sited/repaired (depending on the issue).
