Zones

It also makes sense to understand the term 'zones’ which is very commonly used in burglar alarm terminology.

It is nothing but the area or the total number of sensors that are required to protect an area. They are basically classified into four, i.e. Zone 1 to Zone 4. The first zone is about the delay aspect. It usually refers to the doors where more of the entrance and exiting takes place.

Zone 2 is about instant perimeter which would include other things apart from doors. The master bedroom or the backroom doors are simple examples of these instant perimeters. Zone 3 and 4 deal with the interiors of the area that need to be protected.
