c. Power Supply Fault
d. Sounder Fault
e. Fire Output Fault
f. Fault Output Fault
g. Auxiliary Supply Fault.
Note:
System Fault remains latching at all times.
7.3.2
Mains Fault Delay
By default, a mains fault is indicated within 10 seconds.
This option allows the delay to be extended to 30, 60 or
90 minutes. The 60 minute and 90 minute options do
not comply with EN54 (see information at left).
Note:
The Non-latched faults and Mains fault delay
options can be used together. For example, if the
delay is set to 30 minutes then the fault is indicated
after this time. The indication is removed
automatically 10 seconds after the fault is cleared.
7.4
System Options
The following options are selectable:
a. Clear Checksum
b. Select Default Configuration
7.4.1
Clear Checksum
Use this selection to clear user configuration checksum
faults.
7.4.2
Select Default Configuration
This enables the panel to be returned to the factory-
configured state. When System LED 2 is lit the panel is
in the factory-configured state.
7.5
Fire Zone Input Type
Fire input zones can be configured as follows:
a.
Latching/non-latching alarms
b.
Alarm or for short-circuit operation
c.
Auto or manual operation mode
d.
Coincident-alarm or separate-alarm detection
e.
Setting a Sprinkler Verification Time.
f.

7.5.1
Latching/Non-latching Alarms
A detection zone can be configured as latching or non-
latching. When selected as latching, if the panel enters
the fire (or fault) state this condition will remain active
until the panel is reset. When selected as non-latching,
the panel state returns to normal once the input condition
has been cleared. The default is latching.
EN54-2 : 7.6 & ISO 7240-2
1. Configuring a local
detection zone as non-
latching contravenes the
requirements of EN54 and
ISO 7240.
2. Reset from an alarm state must be a
manual operation at access Level 2.
EN54-4: 5.4
A mains fault MUST
be indicated within 30
minutes.
