6Using intrinsically safe arriers
SIGMA CP control panels support the use of I.S. barriers for connecting to equipment in hazardous areas.
Only certified detectors, call points and sounders may be used in hazardous areas and these
must be connected to the control panel via a compatible I.S. barrier as listed in Table 7.
Connection of the I.S. barrier changes the characteristics of the detection circuit, therefore zones that have
I.S. barriers connected, must be adjusted to work with them.
Programmable options C61 to C68 allow each zone to operate with I.S. barriers.
The amount of detectors and call points that can be connected to a zone is limited by the I.S. approval
system diagram which should be supplied by the detector manufacturer. The power rating of the end of line
resistor will be dependent upon the Zone classification rating (Gas class) this will be specified on the system
diagram.

7Control panel fascia
In addition to the mandatory controls and indications required by the AS724 -2 standard, two seven-
segment LED displays and MODE, SELECT and ENTER buttons are provided to allow easy entry and storage
of codes to configure the control panel to suit the requirements of the installation.
Openin the fascia
The fascia of the control panel is held in place by a screw on the right hand side. Undo the screw and lift
the plate from the right hand side.
Opening the fascia allows more room when mounting the cabinet and fitting cables.

Man-1078_Sigma_CP_AUS_12
Page 11 of 29
8Connecting to the circuit oard
All connections for field wiring are to a single row of terminals along the top of the circuit board.
The connections for the power cables are to a pluggable terminal block which may be pulled off of the board
to remove power from the PCB assembly. Remove this pluggable terminal only with Mains Power OFF.
Cabling must comply with the relevant Australian Standards. The resistance of any core of any cable must
not exceed 25 ohms.
Wiring should enter the enclosure at the top of the panel using the knockouts provided and be formed tidily
to the appropriate terminals leaving only enough wire to ensure that there is no strain on the PCB.
Terminals are capable of accepting wires of up to 2.5mm2.
Terminal designations
Wiring must not go across the front of the circuit board plate or between the plate and the circuit board.
If cable entries need to be in positions other than at the knockouts provided, wiring must be fed behind and
well away from the surface of the circuit board.
The space at the bottom of the enclosure is largely occupied by the standby batteries so this must be borne
in mind when considering cable entries.
9Software revision num er
New features may be added to Sigma CP fire control panels from
time to time and when this is done the operating software of the
unit is updated. The software revision can be located on the main
processor by removing the plate holding the PCB from the
enclosure and turning it over. The software version will have a
number such as “Sig27.hex” and it is this number which will
determine which features the panel has installed and its
compatibility with Sigma CP ancillary board, sounders boards,
repeaters etc.

10 Detection zone wiring
The detection zones provide a nominal 24V DC to power compatible conventional detectors and call points.
The wiring is monitored for open and short circuit fault conditions. The 6K8 end of line monitoring resistors
that are factory fitted to the control panel’s terminals must be removed and placed across the last device
that is wired to the zone circuit.
Wiring can be conventional using standard detector bases (K series), or by the use of special detector bases
it is possible to wire the system such that detection devices and sounders are fitted to the same pair of
wires. (T series)
Detection zone circuits must be wired as a single, radial circuit with no spurs or T junctions to enable the
monitoring circuit to work correctly.
Polarised sounders may also be wired across the detection zone but in reverse polarity to that shown by the
zone terminals (see figure 5 below). Each zone can be configured individually as a 2-wire type zone or a
non 2-wire type zone using configuration options C1 to C8.

Man-1078_Sigma_CP_AUS_12
Page 13 of 29
11 Sounder circuit wiring
All sounders must be of the polarised type. If non-polarised sounders are used the control panel will
permanently show a fault condition.
Sounder circuits are monitored for open and short circuit faults by placing a 1 K end of line monitoring
resistor across the last device on the circuit.
Sounder circuits must be wired as a single, radial circuit with no spurs or T junctions to enable the
monitoring circuit to work correctly.
A maximum of 1.6 Amps is available for powering sounders with a maximum load of .41 Amps on any one
circuit.
12 Connection to remote control terminals
Some functions of the control panel can be controlled externally from the panel if required. Operation of
these inputs must be restricted by an access level 2 control as defined in AS724 -2.These are
abbreviated at the terminals block as follows:
a) Remote V supply – R V
b) Silence Alarm – SIL
c) Sound Alarm – AL
d) Fault – FLT
e) Reset – RST
To activate these inputs, the remote Volt (R V) supply must be connected to the input via a normally open
switch or contact and via a resistance of no greater than 1 ohms.
All of the remote control inputs are non-latching.

13 Aux 24V DC supply
An auxiliary 24V DC supply is provided to enable local signalling or control of ancillary systems such as door
release controllers. The terminals for the Aux 24V supply are labelled Aux 24V and ROV. The ROV terminal
is the negative terminal and is the same terminal that should be used to switch the remote control terminals.
It is possible to make the ROV terminal pulsing so that by connecting it to the AL terminal via a remote volt-
free contact, it can be used to pulse the dedicated sounder circuits in response to a signal from another
system for example to give an alert. See programming code 24.
The supply is fitted with an electronic self-resetting fuse to protect the control panel’s 24V supply in the
event of a wiring fault.
Any standing load on the Aux 24V supply must be taken into account when calculating battery standby times
as standby time will be significantly affected by even modest standing loads. It is recommended that the
Aux24V output is not used to power standing loads and not used to supply loads of greater than 3
milliamps.
Where the Aux 24V supply is used to power electromechanical devices such as relays or door retainers it is
imperative that a suppression diode is fitted across the coil of the electromechanical device to prevent the
generation of high voltage transients back to the control panels power supply. The Aux 24V DC Supply is not
suitable for powering Sigma CP sounder boards, a separate power supply should be used for these.
14 Connection to relay contacts
Volt free changeover relay contacts are provided for local control and signalling if required. These contacts
are rated for switching signalling circuits only and the maximum ratings listed in Table 1should not be
exceeded under any circumstances.
Fault relay
The Fault Relay is normally energised and will de-energise upon any fault condition including total loss of power.
Local fire relay
The Local Fire Relay will energise upon activation of a fire condition on any of the zones or pressing of the
Sound Alarm Button on the front panel. The relay will remain activated until the alarm is silenced or the
panel is reset. This relay will not operate upon activation of the remote AL input or when a fire condition is
triggered on a zone that is in test mode.
Fire relay
The fire relay will energise upon activation of a fire condition on any of the zones. The relay will remain
activated until the control panel is reset. This relay will NOT operate upon activation of the remote AL input.
Individual zones can be configured not to operate the Fire relay by setting configuration options E1 to E8.
15 Connection to Accessory modules
Accessory modules include a Gas Module, Ancillary Relay Module, or an Australian Interface Module.
Accessory modules connect via a 2 core cable to the terminals marked RS485 + and – on the Sigma CP main
control panel PCB. Up to a total of 7 Accessory modules may be connected and each has terminals for the
incoming cables and outgoing cables. All except the last accessory module connected to the cable must
have the jumper links J2 removed.
The address of any accessory modules used within the system must have their address set using the DIP
switch on the module, ensuring that no two modules of the same type share the same address. NOTE: The
Australian Interface Module is fixed at Output unit address 7 and cannot be changed.
Apply power to main panel first and then all accessory modules. Turn ON the Enable Control keyswitch and
set the Write Enable switch to ON then briefly press the Processor Reset button on the main panel. Wait for
a few seconds and the main panel will show the addresses of the modules that were found on the display for
instance “r1” indicates that a module at address 1 has been found.
Turn the Write Enable switch OFF, then ON again and then press the Enter button to accept each module
that has been found. When all modules have been added, set the main panel Write Enable switch to OFF.
Press the Watchdog Reset switch on the main panel.
All modules are now configured and the main control panel will report a fault if any module, that has been
accepted, becomes faulty or goes off-line.

16 Panel operation
16.1 Normal condition
Under normal conditions, control panels will have only the green, Power On LED lit.
16.2 Fire condition
Upon receipt of a fire condition by activation of a detector or call point, the Common Fire indicator will light
and the Fire in one indicators will flash at around 2Hz.
The Fire and Local Fire relays will also operate and signal any systems to which they are connected.
Any sounders connected to the sounder circuits will operate in common, zonal or 2-stage mode as selected
by configuration options 1 to 12 (see Table 8).
16.3 Silence/Sound Alarms
The Silence/Sound alarm button can only be operated at access level two which means that the Enable
Control keyswitch must be activated.
To silence the sounders, activate the Enable Control keyswitch and press the Silence/Sound Alarm button.
When the sounders have been silenced, the Zone Fire LEDs will change from flashing to a steady state.
Pressing the Silence/Sound Alarm whilst the control panel is in this silenced condition will cause the sounders
to operate again.
The sounders can be toggled on and off with the Silence/Sound Alarm button as required.
16.4 Reset
To reset the panel, activate the Enable Control keyswitch then press the Reset button.
16.5 one fault
Removal of a detector from its base or a fault on any of the zone wiring will cause the Fault LED and one
Fault LEDs to light indicating the zone in which the fault has occurred. Zone fault is non-latching and will
automatically reset once the fault has been rectified.
16.6 Sounder fault
A fault on the wiring to sounder circuits will cause the Fault and Sounder Fault LEDs to light indicating a fault
on the wiring to the sounder circuits. Sounder fault is non-latching and will automatically reset once the
fault has been rectified.
16.7 Power fault
Failure of the mains power, disconnection of the standby battery or high impedance in the charging circuit
will cause the Fault and Power Fault LEDs to light indicating an abnormality in the power supply to the
control panel. Power fault is non-latching and will automatically reset once the fault has been rectified.
16.8 System fault
The System Fault LED will light if the configuration memory has not been set or has become corrupt.
System fault is non-latching and will automatically reset once the configuration has been rectified.
16.9 Lamp test
All LED indicators can be tested at any time by pressing the Lamp Test button. The Enable Control
keyswitch does not need to be activated to test the indicators.
16.10 Buzzer Silence
The buzzer can be silenced at any time by pressing the Alarm/Fault Warning Silence button. The Enable
Control keyswitch does not need to be activated to silence the buzzer.

16.11 Disablements
It is possible to disable parts of the system. This may be required if there are works going on in a building
which may cause the fire alarm system to operate in error.
16.12 Disable zones
To disable zones, the Enable Control keyswitch should be activated and the Mode button pressed until “d”
appears in the first of the two seven-segment LED displays. The Select button should then be pressed to
select the number of the zone which is to be disabled in the second of the two seven-segment displays.
Once the desired zone is displayed, the Enter button should be pressed to confirm the disablement.
The Disable LED will light and the one Fault LED will light for each disabled zone.
16.13 Disable sounders
To disable sounder outputs, press the Mode button to select “db” on the seven-segment display. Pressing
Enter will disable all sounders and cause the Disable and Sounder Fault LEDs to light.
16.14 Activate delays
To activate delays on zones as set in configuration options 31 to 48, press the Mode button until “Ad’
appears on the seven-segment LED display. When the Enter button is pressed any zones that are set as
delayed will have their alarm outputs delayed by the time set in configuration options to 9.
16.15 Disable fault contact
The fault relay can be disabled by selecting configuration option 22.
16.16 Test mode
Fire alarm systems must be tested regularly to ensure that they are functioning correctly. The Sigma CP
range of panels enable the system to be tested single handed by using a test mode. When in test mode,
activation of a fire alarm will be automatically reset after a few seconds to eliminate the need to return to
the control panel to reset after every activation.
Test mode is entered in a similar way to disablements. With the Enable Control keyswitch activated, press
the Mode button until “t” appears in the first of the seven-segment displays. Then press the Select button
until the required zone number appears. Pressing the Enter button will cause the Test and one Fault LEDs
to illuminate indicating the zones which are in test mode.
Disablements and zone tests are cleared by repeating the sequence that is used to select them, i.e. the "db"
function (for example) toggles between sounders disabled and sounders enabled.
17 Configuration options
The Sigma CP range of control panels has many configuration options which can be set at the time of
commissioning to suit the requirements of the installation. These options are normally set once and will
rarely need to change. The configuration options are only available at access level 3. To access level 3,
CAREFULLY slide the Write Enable switch (located behind the aperture in the panel plate) to the right
position using a small screwdriver or similar. When the panel is at access level 3, the buzzer will “pip” three
times every few seconds as an indication that it is at this access level.

Man-1078_Sigma_CP_AUS_12
Page 17 of 29
Configuration options are simple to enter using the codes in Table 8below. When the control panel is at
access level 3, the sub-text of the Mode and Select buttons is used to enter a number using tens (+1 ) and
units (+1).
When the required code number is displayed, pressing the Enter button will cause the dot on the units,
seven-segment display to flash. This indicates that a configuration option has been set.
To review which configuration options have been set previously, simply scroll through numbers 1 to 99, A1
to A8, C1 to C8 and E1 to E8 and those with a flashing dot indicate which options have been set.

Once the required configuration options have been set, the Write Enable switch must be returned to its
normal position to the left. The General Fault indicator will remain lit if the Write Enable switch is not turned
OFF.
18 Watchdog reset switch
If for any reason the microprocessor in the control panel fails to carry out its operation correctly it will
attempt to restart itself. This process is called a “watchdog” and the control panel must record and indicate
these events.
If a watchdog event occurs, the control panel will show the Fault and System Faultless on the front panel,
the CPU Faulted inside the panel.

Man-1078_Sigma_CP_AUS_12
Page 20 of 29
This fault can only be cleared by pressing the Watchdog Reset button on the PCB inside the control panel.
The control panel buzzer cannot be silenced and will continue to sound until the watchdog activation is
reset.
19 Processor reset switch
Once started, the microprocessor controlling the panel should continue to run continuously without
interruption. If the microprocessor fails to run correctly it can be reset by pressing the Processor Reset
button on the PCB inside the control panel.
This should not normally be necessary but should be done as a matter of course if the system is behaving
abnormally. The system should resume normal operation within a couple of seconds of pressing the
Processor Reset button. Note: A Watchdog Reset should always be performed following a Processor Reset.
20 Internal indications – trou leshooting
To assist in identifying fault conditions which are not detailed on the front of the control panel, a number of
internal indicators are visible with the front cover removed as follows:
20.1 Mains fail
Indicates that the 23 V AC supply is not present and the system is running on standby batteries.
If there is not a power cut, check the panels mains fuse.
20.2 Batt fail
Indicates that the standby battery has become disconnected, or that the charging circuit of the control panel
has a high resistance or has failed. Check that both batteries are connected and linked together. Test the
battery. Disconnect the battery and ensure that 28 Volts can be measured on battery charger leads.
20.3 CPU fault
Indicates that the central processor unit has failed to correctly execute code and has been re-started by the
system watchdog. The Watchdog Reset switch must be pressed to clear the CPU Fault condition.
If system does not return to normal after the Watchdog Reset switch is pressed then the panel is probably
damaged and the circuit board needs replacing.
20.4 Aux 24V fault
The Aux 24V and R V terminals provide a 5 milliamp, 24V DC power supply for power fire alarm ancillary
equipment. This LED indicates that fuse protecting the R V output has operated and the rating of this
output has been exceeded. The fuse is a self-resetting type and the supply will resume when the fault
condition is removed.
20.5 Batt low
Illuminates when the system is running on batteries and the battery voltage is lower than 21V +/-2% (the
minimum battery voltage).
20.6 Earth fault
Indicates that part of the system wiring is connected to earth. Remove all system wiring and re-connect
cables one at a time until the earth fault returns. This will indicate which cable the earth fault is present on.
20.7 Sys fuse fault
Indicates that the total power rating of the power supply has been exceeded and that the system fuse has
come into operation. Remove and review all loads and re-connect one at a time until over rated circuit trips
fuse to identify troublesome circuit.
20.8 S1 fault and S2 fault
Indicates a short or open circuit on sounder outputs. Remove wiring and refit end of line resistors. Check
sounder circuit wiring.
