Work States
During an alarm, fault or supervisory event on the system, the event is clearly shown by
dedicated LEDs that are labeled
Fire Alarm,
Fault
, and
Supervisory
, respectively. A
detailed explanation in the digital display will include all the details necessary for
troubleshooting the event and proper resolution.
Fire alarms, fault conditions, and supervisory conditions are defined as events. When
two events occur at the same time, the first event will be shown (preference to an alarm)
and at the same time the Memory LED will be turned on to indicated additional events in
the system.
Fire alarms have a higher priority than fault events and are shown first.
To see the events in the order they occur, use the up and down arrow keys.
10.1
Normal State
Normal state is a state where no alarm or fault event and all of the inputs and outputs
are enabled. In this state, the green power LED is turned on and the digital display
moves the figure
8
from left to right.
10.2
Alarm State
10.2.1
Alarm Verification
The alarm verification feature allows the control alarm to ignore momentarily false
alarms that may cause a nuisance.
When a zone is programmed for alarm verification, the control panel resets the zone in
alarm, waits for 0 to 55 seconds (depends on individual zone programming) and
rechecks whether the same zone is still in alarm. During that time, the control panel will
enter alarm state when receiving an alarm from the same or another zone.
During alarm verification time, the control panel will enter alarm state immediately in
case that there is another alarm indication even if that zone is programmed as alarm
verification.
In case only one alarm triggered the alarm verification clock, during and up to 120
seconds, no additional alarm is received, the clock will be reset and the control panel will
be back in normal mode.
10.2.2
