9.6 Selectable Zonal or General
Alarm Sounder operation
The Zonal Alarms DIL switch allows the sounder
circuits to operate zonally in line with the zone in
alarm. The actual operation of the alarm circuits will
vary depending on the type of zone detection and
number of zones available on the panel.
Twin-wire panels (1 to 8 zone):
All twin-wire sounders operate zonally, sounder
circuits on the motherboard operate as general
alarms (i.e. all four alarm circuits on the
motherboard operate for any zone fire)
Standard panels, 1 to 4 zone panels:
Sounder circuits 1 to 4 operate individually for a
fire condition on the respective zone.
Standard panels, 8-zone panel:
Sounder circuits 1 to 4 operate as general
alarms (i.e. all four alarm circuits on the
motherboard operate for any zone fire). Zonal
sounder operation is not available.
9.7 Buzzer Disable
The DISABLE BUZ DIL switch allows the panel
buzzer and Buzzer Active output to be disabled so
tat they do not operate for alarms or faults. The
panel buzzer will still operate for button presses.
The panel does not give any indication that the
buzzer has been disabled. This feature is
provided for use during panel commissioning
and maintenance only. Ensure that the DIL
switch is returned to the OFF position after
commissioning/maintenance tests are
complete.
9.8 Earth Fault monitoring.
The DUO-CEL panel is designed to monitor for low
impedance faults to earth on the field cables. Earth
faults can lead to false alarms or failure to operate
the sounders or other outputs.
For installations where earth fault monitoring is
unsuitable, it can be disabled by removal of the
insulated jumper link (see Figure 3). The link can be
rotated and placed just on one pin rather than
across both pins. This should be done only after
all field cabling has been tested and confirmed
to be free from faults.
10. Panel Repeaters
The DUO-CEL repeaters duplicate the panel
indications and main user controls at a location
remote from the main panel. The repeater uses the
same enclosure & control board as the fire alarm
panel although most of the components are
depopulated from the control board. Up to 3
repeaters can be connected to a single panel using
an RS485 serial connection.
Each repeater can be powered either from the
Auxiliary 24Vdc output of the panel or an internal
power supply (optional).
Note:
The disable/enable/test facilities and the
configuration functions are not available at the
repeaters.
Repeaters cannot be used with the 1 & 2 zone
panels.
