6.6 Panel Configuration.
6.6.1 Basic Default Configuration
When first powered up, the DUO-CEL panel can be
operated in the factory default configuration:
All zones latching fire.
10uF Capacitor EOL (unless selected to
RESISTOR EOL during the installation
procedure), or composite EOL for twin-wire
panels
Sounders – General steady Alarm mode
selected (not zonal, not pulsed).
No zones programmed for dependency.
No repeaters configured
Earth fault monitoring – enabled [link fitted].
Buzzer – enabled.
6.6.2 Site-Specific Configuration
It is possible to tailor the functionality of the DUO-
CEL fire alarm panel in line with site-specific
requirements. Details of the site configurable
options and the configuration process are provided
in section 7 below. The actual configuration can be
recorded in the panel log book. This configuration
is not lost when the panel is powered down.
7. Operating the Engineer’s functions
The Engineer‟s configuration facilities are
controlled by DIL switches located on the
motherboard, accessed by removing the front cover
of the panel. Each configuration feature has its own
dedicated DIL switch. The DIL switches are as
follows:
1: Z1 NON LATCH
2: RESISTOR EOL
3: ALERT MODE
4: DEPEND CONF
5: ZONAL ALARMS
6: S/C FIRE
7: AUX. RESET
8: DISABLE BUZ
9: REP CONFIG (4 & 8 zone only)
10: SNDR EXPAND (not used)
Most functions simply require the appropriate DIL
switch to be either ON or OFF. Switches 2 & 10 are
not used on the Twin-Wire panel and must be set to
the OFF position.
7.1 Zone Dependency (coincidence)
One or more zones can be programmed to
dependency mode.
If a fire condition occurs on a dependency zone, the
panel will not immediately indicate the alarm. A
30-minute counter will be started and the zone will
be reset to clear the detector. After the zone power
is reinstated, if a fire detector or manual call point
is operated within 30 minutes, the panel will raise
the alarm condition.
If no detectors or MCPs are operated before the 30-
minute timer ends, the zone will return to
coincidence detection (i.e. a detector alarm on the
zone will start the 30-minute timer again).
Operation of MCPs will always raise a fire alarm
immediately (unless the MCP is an Alert MCP).
A fire condition on any zone not configured for
dependency will always raise a fire alarm
immediately.
7.1.1 Zone Dependency selection
When the zone dependency configuration DIL
switch (DIL switch 4 – Depend Conf) is switched
to the ON position, the panel sounds the internal
buzzer and illuminates the SYSTEM FAULT LED
to indicate that the programming mode has been
initiated. The current status of the zones is also
displayed on the zone fault LEDs; LED OFF – No
Dependency, LED ON – zone configured for
dependency.
Operation of the select button will then switch the
Select cursor on, flashing at the zone 1 fault LED.
Pressing the Select button again will move the
flashing cursor to the next zone. The cursor will be
switched off after the last zone (1, 2 4 or 8,
depending on the panel) or if no buttons are pressed
for 30 seconds.
Note that in the Dependency Configuration mode,
any faults, tests or disablements are masked and are
not shown on the display. The panel will not
respond to faults or fires.
With the cursor flashing on the required zone,
pressing the Disable button toggles the state of the
Dependency mode for that zone.
Once all required zones have been configured and
the configuration DIL switch is returned to the OFF
position, the panel will return to normal operation.
The programming information is stored in
EEPROM and is not lost during power-down of the
panel.
