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 programmed, by briefly
locking and unlocking the external arming element.
The latter function is intended for persons who
return home late and who must deactivate internal
arming before entering the internally armed zone.
This disarming simultaneously switches off the
internal acoustic signal transmitters.
