Unable to set

When your alarm displays ‘Unable To Set’, this means a sensor within your property is still active/open. This could be movement within an area or a door left open which isn’t in the exit route.

In this situation, you will see that your alarm will also tell you which sensor has been left open and is preventing the alarm to set. You will need to go to that area or sensor and check its closed/check to see what could be setting off the motion sensors.
