High Security Region
(HSR)
High security regions (HSR) require a certain number of high security
users (HSU) present in them to allow any normal users inside. If
a high security user leaves the region causing too few HSU present
in it, an alarm is raised, preceded by prewarning time.
The system does not allow the normal user to stay in the HSR
without HSU inside, therefore the last high security user will not be
permitted to leave the high security area if there are normal users
inside.
High Security User (HSU)
See High Security Region.
