Subdivision Into Zones - ABB SAS-W1.1E System Manual

WARNING!
The technical zone (24h) and Pre-alarm and Internal Alarm modes do not comply
with the EN 50131-1 standard. The functions relating to domestic security, for exam-
ple flooding detectors, smoke detectors, gas detectors and technological detectors
in general, and the Home Automation functions, are not covered by EN 50131 1 and
EN 50131 3 standards.
10.2.2

Subdivision into zones

Subdivision of the intrusion alarm system into zones allows greater flexibility in terms of
management and meeting user needs.
For example, perimeter detectors (e.g. window and door opening) can be associated with
one zone, and passive infra-red detectors with another. This way, the user can activate just
the first zone at night, for when they are asleep, and both when the leave the house unat-
tended. This setting signals intrusion attempts while the user sleeps, but allows people to
move freely as required within the house. The option to activate and deactivate various zones
is also very useful if there is a garage, a shop, an office or a laboratory adjacent to the house.
In such cases, the option of associating the various areas with different zones makes it possi-
ble to protect them selectively, via a single system, arming the anti-intrusion function when
nobody is present.
