ATTENTION! The parameter changes have come into effect after
device power reset. The power reset is not necessary for Net Address and
Interface Response Delay changing.
5.2 Fire alarm operations
The device performs the fire alarm functions if at least one alarm loop
is assigned with the types 1, 2, or 3. If so the device provides the loop op-
eration at following statuses:
− "Armed"
− "Disarmed"
− "Arm Delay"
− "Arm Failed"
− "Fire Signal"
− "Fire Prealarm"
− "Fire Alarm"
− "Fire Trouble"
The alarm loop enters the "Armed" status if it has been just armed
and it resistance is within the normal range. Short-run disturbances less
than 250 ms don’t lead to the status changing.
If during arming the alarm loop parameter “Arming Delay” differs from
zero the loop enters the “Arm Delay” status and its breaking doesn’t lead to
the alarm.
After arming delay period having been elapsed if the loop resistance
is within normal range the loop transits the “Armed” status otherwise “Arm
Failed” status.
If “Auto Rearming when Disarmed” loop parameter is set on then this
loop has automatically been armed and switched from “Arm Failed” to the
“Armed” status if its resistance has been within normal range for more than
3 s.
If the loop resistance has been out of normal range for 300 ms the
device has registered the loop breaking and switched its into the one of the
following statuses:
