6. 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.
6.1 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
immediately.
6.1.1 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,

raise
a

alarm
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.
6.2 Repeater Configuration
The panel can be programmed to communicate
with up to 3 repeaters. Repeaters can only be used
with 4-zone & 8-zone panels.
6.2.1 Repeater selection
When the Repeater configuration DIL switch (Rep
Config) is switched to the ON position, the panel
sounds the internal buzzer and illuminates the
SYSTEM
FAULT
programming mode has been initiated. The current
status of the repeater configuration is also
displayed on the Repeater Fault LEDs, which are
visible when the front cover is removed.
Operation of the Select button will increment the
number of repeaters, up to a maximum of 3, after
which the number is reset to zero.

Once the required quantity of repeaters has 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.
NOTE: Do not connect & configure repeaters
until the panel has been commissioned.
6.3 Invalid Configuration conditions:
An invalid programming condition will exist if both
DIL switch 4 & 9 are in the ON position at the
same time. In this case:
o The System Fault LED will flash.
o The fault relay will operate.
o The panel buzzer will sound.
o The Cursor indication will clear.
o Configuration will be inhibited.
