Hi. Thanks for the reply I've been googling for hours. No idea what am doing. I think the battery in right way but I can double check tomor. Tamper switch?
Tamper switch is located on the board of the device where you put the battery in. It’s a small micro switch that is depressed once the lid of the device is fitted.
Hi took cover off problem sensor. New battery no lights on sensor No noise. battery in correct way. pushed spring in (tamper) no response.The lights do flicker if I wiggle the battery.
