8.3 Selection of Zones or Outputs for
Disablement, Enablement or Test
The panel provides a simple and straightforward
means of selecting the sounder outputs and/or
zones which need to be disabled, re-enabled or set
to the test mode. The Fire Signal Output can also
be disabled and enabled or placed into the test
mode.
The zone or output is selected using the Circuit
Select feature. This allows the user to move a
flashing cursor indication down through the yellow
fault LEDs associated with the available circuits
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.
For each circuit that the Cursor is on, the General
Test and General Disablement LEDs will indicate
the current status of the circuit; flashing Test
indicates the circuit is in Test mode, flashing
Disablement indicates the circuit is disabled. Both
LEDs OFF indicates the circuit is in normal
operation.
If the circuit is in normal operation, pressing the
Disable button once will disable the circuit,
causing the General Disablement LED to flash
and the circuit fault LED to illuminate steady
(with flashing cursor).
If the circuit is in normal operation, pressing the
Test button once will set the circuit to test mode,
causing the General Test LED to flash and the
circuit fault LED to illuminate steady (with
flashing cursor).
If the circuit is currently disabled, pressing the
Disable button once will restore the circuit to
normal, causing the General Disablement LED
to switch off and the circuit fault LED to switch
off (with flashing cursor).
If the circuit is currently in test, pressing the Test
button once will restore the circuit to normal,
causing the General Test LED to switch off and
the circuit fault LED to switch off (with flashing
cursor).
If the circuit is currently disabled, pressing the
Test button once will change the circuit status
from disabled to test mode, causing the General
Disablement LED to switch off and the General
Test LED to flash.
If the circuit is currently in test, pressing the
Disable button once will change the circuit status
from test mode to disabled, causing the General
Test LED to switch off and the General
Disablement LED to flash.
NOTE: Disablements are stored in EEPROM and
are not lost when the panel is powered down. Test
conditions are cleared when the panel is powered
down.
8.4 Disabled Zones and Outputs
Any or all of the zones can be disabled.
A disabled zone will have power supplied to it but
will not report fire or fault conditions. The zone
power is switched off briefly when the zone is
disabled, and also when the zone is re-enabled.
Detectors on a disabled zone are still able to enter
the alarm condition but will not raise a fire alarm on
the panel.
In the twin-wire mode, sounders on disabled zones
will still be activated during a fire alarm unless the
sounders have been disabled.
The fire panel will respond normally to fire device
operations and wiring faults on all enabled zones.
The following outputs can also be disabled and
enabled:
All Sounder circuits including twin-wire (as a
group operation).
The Fire Signal Output.
A disabled output will not report fault conditions and
will not be activated, although power for monitoring
will still be applied.
8.5 Detector Zone Test.
When selected to the Test mode, devices
connected to the zone can be operated for test
purposes without operating the Fire Signal output or
the Fire Relay.
The zone(s) to be set to the One Man Test
condition are selected using the Cursor Select
feature described in 8.3.
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 operate for 5 seconds and then
automatically silence. Sounders operate in
general or zonal mode in accordance with the
panel configuration.
After each test the panel and the device being
tested are 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.
8.6 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 protected area and confirm the operation of all
the sounders. The sounder on/off cycle is 2
seconds on and 15 seconds off to allow operation
