What is the maximum distance between both contacts? I am looking at fixing to my conservatory doors but there is a 2 cm gap with tapered edges between the doors.

Asked by: Spinblitz

Can this product be switched off when you are in the house to save it going off every time I personally want to open my doors or windows?  Thanks  John 

Asked by: Jiemunro
The arming/disarming switch is located underneath the battery compartment, just above the battery slot. There are only two settings, ON and OFF. Whilst ON, the alarm will sound whenever the two parts of the alarm are separated. Whilst OFF, the alarm will not sound under any circumstances.
