Engineer’s Zone/Output Configuration
Process:
Various
programmable
configuration
options
associated with the zonal inputs and outputs can be
enabled/disabled by operating the appropriate DIL
switch located within the panel enclosure. 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: Configure Machinery Space Zones feature is
not used on the Precept EN panels.

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
If the panel is in the fire alarm condition,
silence the alarms and reset.
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 Panel’s
System Fault
LED will flash and
the buzzer will operate.
The Select LED on the front of the display
will pulse.
Any standing fire or fault alarm indications
and associated outputs will be inhibited.
If active, the indications for evacuation,
silence buzzer, delay on or disablement
indications will clear.
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.
A steady indication denotes that the
zone/output is already configured to the
selected mode.
No indication denotes that the zone/output
has not been 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
switch 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 reverse
[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:
Operation of the ENABLE button will apply the
configuration functionality to the selected
zone/output
causing
the
associated
fault/disabled LED to provide a continuous
indication.
Operation of the DISABLE button will clear the
configuration from the selection and restore
normal operation. The fault/disabled LED will
clear.
By repeating steps 2 and 3, any number of
zones [or outputs] can be configured.
4. To quit the programmable configuration
mode:
o
To return the panel to normal operating mode
applying the updated configuration:
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, 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.
