12.6 SYSTEM STATES & INDICATIONS
Faults, alarms and system faults can be recalled using the Recall key.
A recall of system faults will display in addition to system faults, any system states (such as
trial evac) that are present.
The bells isolate LED flashes at 2Hz when the local silence alarms switch is activated,
flashes at 1Hz when the bells are silenced by a bells isolate or silence alarms at some other
panel, and is on steady when the bells are isolated locally.
Door Interlock Buzzer
If the door is closed when any of the brigade isolate/test, services restore, trial evac, silence
alarms inputs are asserted, or the bells are isolated locally, or the database is write enabled,
then the buzzer sounds a unique cadence to warn the user.
Abnormal Conditions
The NDU sends a state of "abnormal" on the network when it has any local off normal
condition.
The common normal LED on the NZ Display Extender Board is off and the NML logic token
is false whenever any of the following are true.
1. There is any local abnormal condition (refer below).
2. There is a "local" abnormal condition at any panel on the network that the NDU is
programmed to "indicate for" i.e any panel in the SID list of the NDU with the "use MAF
relay data" option enabled.
3. There is any off normal total in the list of totals shown on the base display of the NDU.
This includes any off normal totals that come from other panels on the network that the
NDU is programmed to show totals for. i.e any panel in the NDU SID list that has the
"use MAF totals" option enabled.
Local Abnormal Conditions
The conditions that generate local abnormal are:
1. Any alarm, fault or isolate state on any of the NDUs 16 zones that are not "Status
Only".
2. Any fault or isolate state on any of ancillary 1, ancillary 2 or bells relays on the
MAF/PSU board.
3. When the "plant" is isolated i.e. when the logic token PLI is true.
4. When the bells are locally isolated.
5. When there is a latched battery very low alarm state.
6. When the panel is in program mode or the database is write enabled.
7. When any of silence alarms, trial evac, services restore, brigade isolate or brigade test
are locally operated.
8. When there is any battery, mains or charger fault. Battery faults include battery low,
battery connection and battery capacity faults. This does not include failure of a
manual battery test.
9. When there is a battery very low state and battery very low alarm is disabled.
10. Evac defect or external defect true if enabled to be fault.
