Example: The magnetic detector always sends a signal to the control panel every time the door is opened. So why
doesn't the alarm go off with the system disabled? This happens because the control panel, during processing, also
knows that the system is disabled and so ignores the signal received. The control panel can be even more intelligent.
If a "bell" function was activated for a specific detector during the system configuration phase (the name used by the
control panel may differ, for example some control panels use the term "gong"), then when the system is disarmed every
time that detector is activated, opening the door or walking in front of will cause the control panel to activate a sound. The
signal from the magnetic contact is physically the same, but the way the control panel interprets it changes, producing
different results.
Here is how and where zones can be conveniently used.
A first opportunity was illustrated in How to protect areas and people. In that case it was best to make at least two zones:
one for perimeter protection and the other for trap protection. In this way, at night it is possible to move freely about the
house while being protected from attempted night-time intrusions. When there is no one at home, both the zones, can be
armed to raise the level of security.
Other examples of how the system can be divided into zones are:

Home with separate garage. In this case three zones can be configured: perimeter, trap, and garage;

Residence and professional office or shop located in the same building and formally separated from each other. In
this case, three zones may be configured: residence perimeter, residence and perimeter trap, and office/shop trap;

Office and warehouses: In this care even more zones can be configured for the offices as well as the warehouses
in order to provide the utmost flexibility in protection without hampering work activities.
As a general rule, when in doubt, lean toward creating one zone more rather than having one less.
Warehouse
ZONE 1
In the example above, the apartment is a single zone, while the rooms on the ground floor, which are used for other
activities, belong to different zones.
In this way it will be possible to protect the warehouse and offices with the alarm system even when the store is open.
IMPORTANT!
Be careful about protecting the same areas by detectors belonging to different zones because there may be a
risk of false alarms caused by a detector left armed when the user thought all of them had been disarmed.
The coexistence of any zone with the perimeter protection zone is at low risk because of the very nature of its
use.
