3.4.2.1
Intrusion
– First entry
The activation of the detector triggers the longer "Delay times entry way" of the partitions associated with the detector.
During this interval, the activations of the "Way" specialised detectors that have at least one partition in common are ignored. Once the
“Delay times entry way” has expired, an intrusion alarm is generated.
The “Delay times entry way”, and consequently the generation of the alarm, can be interrupted:
by disarming all the partitions with OR associations to which the detector belongs, or
by disarming at least one of the partitions with AND associations to which the detector belongs.
When the “Delay times entry way” is already running, all the activations of the "First entry" specialised detectors belonging to the
partitions associated with the detector whose activation triggered the delay time are ignored.
The activations of the “First entry” specialised detectors that belong to other partitions are instead managed independently, each with
its own “Time entry way”.
3.4.2.2
Intrusion
– Way
The activation of the detectors triggers the Intrusion alarm, unless it is running the “Time entry way” or the “Time exit way” of:
all the partitions with AND associations to which the detector belongs, or
at least one of the partitions with an OR association to which the detector belongs.
If the “Time entry way” is not running, the activation of the detector generates an intrusion alarm immediately.
3.4.2.3
Intrusion
– Last exit
When the detector returns to stand-
by (magnetic contact closed, no movement for IR detector etc.), it interrupts all the potential “Times
exit way” active in the partitions associated with it (resetting them at “zero”). This interruption occurs with about 5 seconds delay
compared to the real detector stand-
by to prevent the involuntary generation of alarms during the exit phase. The opening of a “Last
exit” Intrusion input belonging to an activated partition, after the “Time exit way” is expired generates an Intrusion alarm.
3.4.2.4
Intrusion
– First entry – Last exit
Combine the “First entry” and “Last exit” behaviours to enable the use of the same access door for both exit and entry.
The passing of the time can be marked by the sounding of keypad buzzer
s for both the “Time entry way” and “Time exit way”.
