2. Ensure that the resistance of all cables to earth
and between cores is at least 2M.
Check the following:
i) Positive to earth resistance is 2M or
greater.
ii) Negative to earth resistance is 2M or
greater.
iii) Positive to negative resistance is 2M or
greater.
3. Connect a wire link as the end-of-line device on
each of the zones and alarm circuits. At the
panel end, measure the resistance across the
positive & negative ends of the cables for each
of the circuits; ensuring the value does not
exceed 20 for alarm circuits and 7.2 for twin-
wire zone circuits (detection-only zone circuits
can be up to 20). Remember to remove the
wire links after the tests.
Maintain correct polarity throughout all circuits.
Check and rectify any faults.
4. All sounders, detector heads and call points
should now be connected. Remember to
remove any links fitted to detector bases. Be
very careful to maintain correct polarity at each
device
NOTE: For twin-wire circuits, ensure that all
detector heads are fitted. On power-up, the
panel will determine the zone quiescent
condition and monitor for head removal
below this point, so if a detector base (or
sounder base) is empty it must be linked
through for correct monitoring.
5.5 Powering up
Prior to powering up, the panel will have been
installed in accordance with the installation
instructions, all cabling will have been fully installed
and tested, glanded into the panel enclosure but
not connected to the panel terminals. The mains
supply should be isolated externally to the panel.
1. Final battery connections:
a. Connect the blue battery lead across the
red & black battery terminals either side of
the battery clamp.
b. Connect the red battery lead to the
BATTERY POSITIVE spade terminal on the
control board.
c. DO NOT connect the other end of the red
battery lead to the battery at this stage.
2. Once the permit to energise the mains supply
is in place, energise the mains at the external
isolator switch.
The panel should switch on, illuminating the
SUPPLY ON LED and flashing the PSU
FAULT LED. The internal buzzer should pulse.
3. Connect the red battery lead to the red battery
terminal of the left-most battery.
After a short period (less than 60 seconds) the
internal buzzer should silence and the PSU
FAULT LED should extinguish.
The only indication should be the SUPPLY ON
LED.
This is referred to as the quiescent condition of
the panel.
If any other indications are present, identify the
affected circuit and rectify the fault (incorrect or
missing EOL, EOL wrong polarity, battery fuse
blown, DIL switches incorrectly set etc).
4. With no panel access key inserted, press the
Test button. The panel should respond by
illuminating all indications and sounding the
buzzer. This will continue for 5 seconds after
the button is released.
5.6 Panel Configuration.
5.6.1 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.
5.6.2 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 6 below. The actual configuration can be
recorded in the panel log book. This configuration is
not lost when the panel is powered down.
