doesn’t cause the device to consider the loop status as an alarm.
If an alarm loop of Type 5 is configured with the nonzero Arming Delay, while being armed this loop
initially gets Arming Delay status. If the loop is broken but the delay time has not yet expired then no
alarms are produced.
When the Alarm Delay has expired and if the loop resistance is within the normal range then the alarm
loop is considered as Armed. Otherwise, if the Arming Delay time has expired but the loop resistance is
outside the normal range then the alarm loop gets the Arming Failed status.
If the alarm loop is programmed with the Auto Rearming After Failing parameter being set on, it auto-
matically switches from the Arming Failed status to the Armed status when its resistance has come
back to the normal range for at least 3 seconds.
An alarm loop of the Type 5 switches from the Armed status to the Intrusion Alarm status if:
−
The loop has been broken for more than 70ms, the 300-ms Integration Time being set off
−
The loop has been broken for more than 300ms, the 300-ms Integration Time being set on
−
The loop resistance has jumped by more than 10%, the 10% Deviation Blocking being disa-
bled
When the alarm loop has entered the Intrusion Alarm status then relay control in accordance with #1 -
#8 executive programs can be activated (if programmed).
If the parameter Auto Arming After Alarm is set for on the alarm loop then the loop will be automatically
armed and switches from the Intrusion Alarm to the Arming Delay status after its resistance being in the
normal range for at least the 15 times Alarm Delay value configured for the loop (in seconds).
An alarm loop of the Type 5 switches from the Disarmed status to the Tamper Alarm status when the
contacts of the tamper switch of the detector included into this loop has been opened for more than 300
ms. If then the detector enclosure has been restored and the tamper switch contacts have been closed
for more than 15 s, the alarm loop of the Type 5 comes back to the Disarmed status.
An alarm loop of the Type 5 switches from the Disarmed status to the Short Circuit Failure status when
this failure has happened and held for more than 300 ms. When the failure has been repaired for more
than 3 s (the resistance of the loop has been within the normal range) the loop of the Type 5 comes
back to the Disarmed status.
Entrance Alarms
The Signal-10 device can operate as an entrance alarm control if at least one of its alarm loops is con-
figured with the Type 7. For such the loop the device can recognize the following statuses:
Armed
Arming Delay
Arming Failed
