12.3 Presence security
Presence security does not require that the secured zone be vacated. Partial zone arming is possible with
this form of security, i.e you can disable detector groups. It is then possible to move about within these
detector groups without releasing an alarm by actuating a motion detector or a window contact, for
example. Internal arming is carried out using operating units.
An impending alarm criterion releases an internal alarm. The displays
of operating units and parallel boards are not blanked - this means that
the system status is immediately recognizable.
Presence security can be cancelled by disarming using operating
units or, if installed ID card readers.
This disarming simultaneously switches off the internal acoustic
signal transmitters.
