14. Operating the Engineer’s
functions
14.1 Engineer’s Zone/Output Configuration
Process:
Various configurable options associated with the
zone circuits and outputs can be programmed via
the Engineer’s Configuration Mode, enabled via DIL
switches on the panel motherboard. These are:
o
Configure zones as delayed zones.
o
Configure zones for use with I.S.
barriers/isolators.
o
Configure zones as latching/non-latching fire
indication.
o
Configure zones to short circuit fire mode.
o
Configure outputs to be delayed.
Note: The DIL switch labelled Configure M/S Zones
is not used on the Precept EN13 panels.
14.2 Zone or Output Configuration
1. Select a programmable configuration mode:
o
Enable the controls on the display, by turning
the Access Keyswitch on the panel display to
the “1” position.
o
Ensure the panel is in the quiescent state (no
faults or alarms).
o
Open the panel door and locate the
appropriate DIL switch on the motherboard
[
Config Non-latch Zones; Config I.S. Zones;
Config Delay Zones; Config Delay O/Ps
] and
move the switch to the ON position.
The
CONFIG ENABLED
LED on the
motherboard will illuminate.
The
System Fault
LED on the display will
flash and the buzzer will sound.
The
Select
LED on the display will pulse.
The panel will indicate the current status of
the selected programmable configuration
mode on the yellow
fault/disabled
LEDs on
the Zones, Sounders, Fire Routing and Fire
Protection outputs
(dependent on
configuration mode selected).
An illuminated LED denotes that the relevant
circuit is already configured to the selected
mode.
An extinguished LED denotes that the
relevant circuit is not configured to the
selected mode.
o
Close the panel door to allow access to the
buttons on the display.
2. Select a zone or output to be configured:
o
On the panel display, press the Select On/Off
button to enable the Select Mode.
The Select LED will become steady and the
panel buzzer will silence.
A pulsing indication [cursor] will appear either
on the Zone 1 Fault/Disabled LED or the
Sounder Fault/Disabled LED/Test depending
upon which configuration DIL switch is
selected.
o
Use the Select
↑
and Select↓ buttons to scroll
the cursor indication through the selectable
options;
For zonal configuration, through all zones
sequentially in forward [Select↓] or re
verse
[Select ↑] sequence starting at zone 1.
For Output Delay configuration, through
Sounders, Fire Protection and Fire Routing
outputs in forward [Select↓] or reverse
[Select ↑] sequence starting at Sounders.
3. To change the configuration of a selected
zone or output:
With the cursor flashing on the selected zone or
output:
Pressing the ENABLE button will apply the
configuration to the selected zone/output
causing the associated fault/disabled LED to
illuminate steady (the cursor will continue to
flash intermittently).
Pressing the DISABLE button will clear the
configuration and restore default operation.
The fault/disabled LED will extinguish (the
cursor will continue to flash intermittently).
By repeating steps 1 and 3, any number of
zones and/or outputs can be configured.
Note: Any changes to the configuration take
effect immediately and do not require a
separate operation to be stored. Changes are
stored in EEPROM and are not lost when the
panel is powered down.
4. To quit the programmable configuration
mode:
o
Open the panel door and return the selected
Config DIL switch on the motherboard to the
OFF position.
The
CONFIG ENABLED
LED on the
motherboard will clear, the panel buzzer will
silence and the flashing System Fault
indication and zone/output configuration
status indications on the display will clear as
will the cursor and the Select indications. Any
current alarms, fault or disablements, will be
re-indicated along with any active status
indications [Delay on etc.].
o
Close and lock the panel door.
o
Return the ACCESS Keyswitch to the “0”
position to disable the controls on the display.
IMPORTANT NOTE: WHILE THE PANEL IS
IN THE ENGINEER’S ZONAL/OUTPUT
CONFIGURATION MODE, ALL ZONAL
INPUTS ARE IN PERMANENT RESET AND
OUTPUTS ARE INHIBITED - THE PANEL
WILL NOT RESPOND TO ANY FIRE ALARM.
