16.3 Selection of Zones or Outputs for
Disablement, Enablement or Test
The panel provides a simple and straightforward
means for selecting the sounder outputs and/or
zones which are to be disabled, re-enabled or set to
the test mode. The Fire Output, Fire Protection
output and Fault Output can also be individually
disabled and enabled.
The zone or output is selected using the Cursor
Select feature. This allows the user to move a
flashing cursor indication up or down through the
yellow fault LEDs associated with the available
zones and outputs until the required zone or output
is highlighted. The yellow LED for the selected
zone/output flashes in “Cursor” mode, which is
easily distinguishable from all other indications.
With the cursor flashing on the required
zone/output, pressing the Disable button disables
the zone/output. Pressing the Enable button re-
enables the zone/output. Pressing the Test button
initiates the test condition. [Note: Fire Output, Fire
Protection Output and Fault Output cannot be
placed in a test condition].
16.4 Disablement/Re-enablement of
Detection Zones and Outputs
Any or all of the zones can be disabled.
A disabled zone will not report fire or fault
conditions. The fire panel will respond normally to
fire device operations and wiring faults on all
enabled zones.
The following outputs can also be individually
disabled/enabled:
•
All Sounder circuits.
•
The Fire Output.
•
The Fire Protection Output.
•
The Fault Output.
A disabled output will not report fault conditions and
will not operate during a fault/fire alarm condition.
The only exception to this is the Muster Alarm
function which always operates the sounder circuits
even if they are disabled.
16.5 Detector Zone One Man Test
When selected to the One Man Test condition,
devices connected to the zone can be operated for
test purposes without operating the Fire output or
the Fire Protection outputs.
The zones to be set to the One Man Test condition
are selected using the Cursor Select feature
described in 16.3. With the cursor flashing on the
required zone, pressing the Test button initiates the
zone test. Pressing the Enable button or pressing
the Test button again clears the test condition and
restores normal operation to the zone.
The features of the One Man Zone Test condition
are:
•
A fire condition on a zone in Test Mode will not
operate any of the fire outputs.
•
Sounders can be configured not to respond to a
detector test or to operate for 5 seconds and
then automatically silence. When selected to
respond to the detector zone test, sounders
operate in general or zonal mode in accordance
with the panel configuration.
•
The panel will respond normally to a fire
condition on any zone not selected to the Test
Mode.
•
After each test the panel and the device being
tested is automatically reset allowing the next
device to be tested without needing to return to
the panel to silence and reset.
•
If a fire condition occurs on any zone other than
a zone in test mode, the panel responds fully to
the fire condition as per its normal fire response
and configuration. In this case the zone(s) in test
will not be reset automatically.
16.6 Alarm Sounder One Man Test
The One Man Sounder Test operates all sounders
on an intermittent basis until the Test mode is
manually cleared. This allows an engineer to walk
the vessel and confirm the operation of all the
sounders. The sounder on/off cycle is 2 seconds on
and 15 seconds off to allow operation to be
confirmed without being too intrusive.
A genuine fire alarm condition overrides the test
mode and operates the sounders normally.
16.7 Turning the Delay Mode on/off
STANDARD (NON-CREW) MODE:
The delay is automatically turned on when any
of the outputs are configured to be delayed and
automatically turned off when all of the outputs
are configured not to be delayed. The DELAY
LED illuminates to indicate that the delay is on.
Pressing the DISABLE button will illuminate the
relevant fault LEDs to show which circuits have
been set to the delay mode.
CREW MODE:
CREW mode is enabled by setting DIL switch
2/6 OFF & 2/7 ON.
The delay is automatically turned on in Crew
mode and applies to all sounder circuits except
circuits 1 & 2 on the panel motherboard.
Sounder circuit 2 is intended for Bridge/crew
areas and is never delayed.
Sounder circuit 1 is intended for machinery
space areas and is not delayed for a detector
alarm in a machinery space zone but is delayed
for a detector alarm in any other zone.
