INTRUSION&FIRE ALARM ADDRESSABLE 20-LOOP CONTROL DEVICE

5.3 Burglary alarm operations
Depending on alarm loop type the device enables several burglary
alarm modes:
−
Burglary alarm (the loop type 4)
−
Burglary alarm with tamper check (the loop type 5)
−
Entering alarm
−
Alarming
5.3.1 Burglary alarm mode
The device performs the burglary alarm functions if at least one con-
nected loop type is set to 4. The supplied statuses are as follows:
−
"Armed"
−
"Disarmed"
−
"Arm Delay"
−
"Arm Failed"
−
"Intrusion Alarm"
"Armed", "Arm Delay" and "Arm Failed" statuses are similarly to the
corresponding statuses of the fire loops as mentioned above in section 5.2.
The duration of short-run disturbances don’t leading to the status changing
is equal to 50 ms in case of “Integrating 300 ms” parameter being set off
and 250 ms otherwise.
The loop transits from “Armed” to “Intrusion Alarm” status in case of:
−
Loop breaking duration has exceed 70 ms and “Integrating 300 ms”
parameter is set off
−
Loop breaking duration has exceed 300 ms and “Integrating 300
ms” parameter is set on
−
Loop resistance has skipped more than 10% of its value, “10% De-
viation Blocking” parameter being set off
During “Intrusion Alarm” transition the relay control is activating in ac-
cording with the 1…8 programs.
If “Auto Rearming when Fire/Alarm” loop parameter is set on then this
loop is automatically armed and transits from “Intrusion Alarm” to the “Arm
Delay” status after its resistance has been within normal range for 15-fold
“Fire/Alarm Delay” sec.
5.3.2 Burglary alarm with tamper check
The device performs the burglary alarm functions with tamper check
if at least one connected loop type is set to 5. The supplied statuses are as
follows:
−
"Armed"
−
"Disarmed"
−
"Arm Delay"
−
"Arm Failed"
