0B1. Introduction
The SIGMA CP range consists of a series of conventional fire alarm control panels designed in accordance
with European standards EN54-2 and EN54-4 Fire Detection and Fire Alarm systems - Control and Indicating
Equipment.
The range consists of 2, 4 and 8 zone control panels. All control panels are available in two versions:
Sigma K11 range in which detectors and call points are wired on separate circuits to sounders (two sounder
circuits are provided).
Sigma T11 range in which detectors, call points and sounders are wired to the same pair of cables. This is
what is commonly referred to as a two-wire system.
Wiring sounders to the detection circuits eliminates the need to install sounder circuit cables and also offers
the ability to provide zoned or two stage sounder operation.
All control panels have an integral, mains powered battery charger and power supply designed in
accordance with the requirements of EN54-4.
In addition to the requirements of EN54-2 the control panel has the following facilities:
…………. Test condition to allow the automatic resetting of zones in alarm for testing purposes. EN54-2
Section 10 option with requirements.
…………. Delay of the actioning of fire alarm devices (sounders) so that an alarm may be verified before a
premises is evacuated. EN54-2 Section 7.11 option with requirements.
…………. Fire alarm devices to enable an audible warning to be sounded throughout a premises upon the
detection of a fire condition or the operation of a manual call point. EN54-2 Section 7.8 option with
requirements.
In addition to the requirements of EN54-2, all control panels have voltage free relay contacts for fire and
local fire which operate upon fire condition. These are to be used for local control and signalling.
1B2. Safety and mounting

(iii) Statutory requirements
(iv) Any instructions specifically advised by the manufacturer
According to the provisions of the Act you are therefore requested to take such steps as are necessary to
ensure that you make any appropriate information about this product available to anyone concerned with its
use.
This equipment is designed to be operated from 230V 50Hz mains supplies and is of class 1 construction. As
such it must be connected to a protective earthing conductor in the fixed wiring of the installation and a
readily accessible double pole disconnect device meeting the requirements of EN60950/IEC950 which
disconnects live and neutral simultaneously shall be incorporated in the fixed wiring.
Switch disconnect devices such as MK Sentry 63A or similar are suitable for this.
Failure to ensure that all conductive accessible parts of this equipment are adequately bonded
to the protective earth will render the equipment unsafe.
This control panel is designed for indoor use only and at temperatures between -50C (+/- 3) and +400C (+/-
2) and with a maximum relative humidity of 95%.
The IP rating for the enclosure is IP30.
Operation outside of these limits may render the equipment unsafe.

Mounting
The control panel should be mounted on a dry, flat surface, at eye height to the display and in a level
position such that the enclosure is not distorted.
Screws or bolts of a minimum of 5mm diameter must be used to mount the enclosure in all three mounting
positions.
It should be positioned in an accessible position as agreed with the end user.
Suitable fixings should be used at all fixing points such that the control panel is securely mounted and is not
liable to move once fixed.
The control panel should not be mounted in another enclosure or near sources of excessive heat.
Cables should be connected using suitable cable glands fitted to the knockouts provided. If additional cable
entry points are required, all swarf and debris caused by drilling of additional cable entries must be cleared
before power is applied to the panel.

Although the current consumption of many detection devices would allow more than 32 to be connected to a
zone, this number should be limited to 32 to ensure that a short or open circuit on the wiring does not
prevent the indication of a fire alarm from more than 32 fire detectors and/or call points as required by
European standard EN54-2.
No more than 32 detectors and call points should be fitted to any one zone.

3B4. Using intrinsically safe barriers
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 so 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.

4B5. Control panel fascia
In addition to the mandatory controls and indications required by the EN54-2 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.
Removing the fascia
Before the fascia can be removed it will be necessary to unplug the three way terminal block on the left
hand side of the PCB.
The fascia of the control panel is held in place by countersunk screws. Undo the two screws and lift the
fascia gently away from the box towards you.
With the fascia removed there is much more room inside the panel for making off and dressing cables.
When cabling work is complete the fascia can be re-fitted with the two countersunk screws and the red,
green/yellow and black wires re-connected to the three way terminal block.
It is most important that the polarity of the red and black wires is observed as wrong
connection of these will damage the control panel.

Man-1078_Sigma_CP_22
Page 10 of 24
5B6. Connecting to the circuit board
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 the plate/PCB assembly. Remove this pluggable terminal only with mains power off.
Shielded fire alarm cable such as FP200 and metal cable glands must be used for all connections to the
panel.
The resistance of any core of any cable must not exceed 25 ohms. The shield of the cable must be bonded
securely to the enclosure via a metal gland.
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.

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.
6B7. Software revision number
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.

Figure 5.- T series detection zone wiring
7B8. Detection zone wiring
The detection zones provide a nominal 24V DC to power conventional detectors and call points as listed in
the compatibility tables on pages 6 and 7.
The wiring is monitored for open and short circuit fault conditions by removing the 6K8 end of line
monitoring resistors that are supplied fitted to the control panels’ terminals and placing them across the last
device that is wired to the zone circuit.
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.
On T series panels, polarised sounders must also be wired across the detection zone but in reverse polarity
to that shown by the zone terminals (see figure 5 below). At least one sounder should be fitted to each
detection zone. 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.
For non 2-wire systems that are required to comply with BS5839 Part 1: 2002 detector removal
requirements, detector bases fitted with a Schottky diode should be used and the end of line resistor
replaced with an LCMU active end of line monitoring device.

Man-1078_Sigma_CP_22
Page 12 of 24
8B9. Sounder circuit wiring
Whether using standard or T series control panels, all sounders must be of the polarised type. If non-
polarised sounders are used the control panel will permanently show a fault condition. See table 6 on page 7
for a list of compatible sounder types.
Sounder circuits are monitored for open and short circuit faults by placing a 10K 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 0.41 Amps on any one
circuit.
9B10. 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 EN54-2 These are
abbreviated at the terminals block as follows:
a) Remote 0 V supply - ROV
b) Silence Alarm –SIL
c) Sound Alarm –AL
d) Fault –FLT
e) Reset –RST
To activate these inputs, the remote 0 Volt (R0V) supply must be connected to the input via a normally open
switch or contact and via a resistance of no greater than 100 ohms.
All of the remote control inputs are non-latching.

10B11. 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 300
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.
11B12. 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 1 on page 5 should
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.
12B13. Connection to Repeater panels
Repeater panels connect via a 2 core cable to the terminals marked RS485 + and –on the Sigma CP main
control panel PCB. Up to 7 repeaters may be connected and each repeater has terminals for the incoming
cables and outgoing cables. All except the last ancillary board, sounder board or repeater panel connected to
the cable must have the jumper links J2 removed.
Set the repeater address using the DIP switch (SW7); ensure no two repeaters share the same address.
Apply power to main panel first and then all repeater panels. 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 repeaters that were found on the display for
instance r1 indicates that a repeater at address 1 has been found.
Turn the write enable switch of, then on again and then press the ENTER button to accept each repeater
that has been found. When all repeaters have been added, set the main panel Write Enable switch to off.
Press the Watchdog reset switch on the main panel.
All repeaters are now configured and the main control panel will report a fault if any repeaters that have
been accepted become faulty or go off line.
For full details of commissioning procedures for repeaters see the Sigma CP Repeater Operation and
maintenance manual.
Please note that repeaters can only be fitted to panels containing boards labeled
S4XXA or above. They will not work with panels containing boards without an alpha
suffix.

Man-1078_Sigma_CP_22
Page 14 of 24
For panels with software version Sigma242.hex or below, the Enable controls keyswitch and Write Enable
switch must both be set to off.
13B14. Connection to Ancillary boards
Ancillary boards connect via a 2 core cable to the terminals marked RS485 + and –on the Sigma CP main
control panel PCB. Up to 7 Ancillary boards may be connected and each board has terminals for the
incoming cables and outgoing cables. All except the last ancillary board, sounder board or repeater panel
connected to the cable must have the jumper links J2 removed.
Set the ancillary board address using the DIP switch (SW2); ensure no two ancillary boards share the same
address.
Apply power to main panel and all ancillary boards then turn on the enable keyswitch and set the write
enable slide switch to on, 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 ancillary boards that were found on the display
for instance o1 indicates that an ancillary board at address 1 has been found.
Press the ENTER button to accept each ancillary board that has been found.
The control panel will report a fault if any ancillary boards that have been accepted
become faulty or go off line.
For full details of commissioning procedures for ancillary boards see the Sigma CP Ancillary board Operation
and maintenance manual.
Please note that Ancillary boards can only be fitted to panels containing boards
labelled S4XXA or above. They will not work with panels containing boards without
an alpha suffix.
14B15. Connection to 8 way Sounder boards
Sounder boards connect via a 2 core cable to the terminals marked RS485 + and –on the Sigma CP main
control panel PCB. Up to 7 Sounder boards may be connected and each board has terminals for the
incoming cables and outgoing cables. All except the last Ancillary board, Sounder board or Repeater
connected to the cable must have the jumper links J2 removed. Sounder boards must be powered from a
separate power supply which is suitably rated to supply the full sounder load that is connected. This can be
up to 4 Amps if all circuits are fully loaded.
Set the Sounder board address using the DIP switch (SW2); ensure no two Sounder boards share the same
address.
Apply power to main panel and all Sounder boards then turn on the enable keyswitch and set the write
enable slide switch to on, 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 sounder boards that were found on the display
for instance b1 indicates that a sounder board at address 1 has been found.
Press the ENTER button to accept each Sounder board that has been found.
The control panel will report a sounder fault if any Sounder boards that have been
accepted become faulty, have cable faults on their outputs or go off line.
For full details of commissioning procedures for Sounder boards see the Sigma CP Sounder board Operation
and maintenance manual.
Please note that Sounder boards can only be fitted to panels containing software
SIGMA242.HEX or later.

15B16. Panel operation
24B16.1 Normal condition
Under normal conditions, control panels will have only the green, Power On LED lit.
25B16.2 Fire condition
Upon receipt of a fire condition by activation of a detector or call point, the Common Fire indicator will light
and the zonal Fire 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 10 to 12 (see table 8).
26B16.3 Silence/sound alarms
The Silence/Sound alarm button can only be operated at access level two which means that the Enable
Control key must be inserted.
To silence the sounders, insert the Enable Control key 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.
27B16.4 Reset
To reset the panel, insert the Enable key then press the Reset button.
28B16.5 Zone fault
Removal of a detector from its base or a fault on any of the zone wiring will cause the Fault LED and Zone
Fault LEDs to light indicating the zone in which the fault has occurred.
29B16.6 Sounder fault
A fault on the wiring to sounder circuits will cause the Fau lt and Sounder Fault LEDs to light indicating a fault
on the wiring to the sounder circuits.
30B16.7 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.
31B16.8 System fault
The System Fault LED will light if the configuration memory has not been set or has become corrupt.
32B16.9 Lamp test
All LED indicators can be tested at any time by pressing the Lamp Test button. The Enable Control key does
not need to be inserted to test the indicators.
The buzzer can be silenced at any time by pressing the Buzzer Silence button. The enable key does not need
to be inserted to silence the buzzer.
33B16.10 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.
34B16.10.1 Disable zones
To disable zones, the Enable Control key should be inserted 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 Zone Fault LED will light for each disabled zone.
A disabled zone is shown on the seven segment display as ‘dx.’ (where x is the zone number from 1-8).
If the ‘x’ is flashing, it means that there are activated devices in that zone and re-enabling it will put the
control panel into the fire condition.
The panel should be Reset before enabling any zone with a flashing “dx.” Indication

Man-1078_Sigma_CP_22
Page 16 of 24
Note: The flashing “dx” indicator will only appear on panels with software version sigma_CP 214.hex and
higher produced after July 2012.
35B16.10.2 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.
36B16.10.3 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 00 to 09.
37B16.10.4 Disable fault contact
The fault relay can be disabled by selecting configuration option 22.
38B16.11 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 key inserted, 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 Zone 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.
16B17. 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.
Configuration options are simple to enter using the codes in table 8 below. 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 (+10) 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 right. The General fault indicator will remain lit if the Write enable switch is not turned
off.
17B18. 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 FAULT LEDs on the front
panel, the CPU fault LED inside the panel.
This fault can only be cleared by pressing the WATCHDOG RESET button on the PCB inside the control
panel. The control panel buzzer can not be silenced and will continue to sound until the watchdog activation
is reset.
1819. 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.
19B20. Internal indications –troubleshooting
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:
39B20.1 Mains fail
Indicates that the 230V 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.
40B20.2 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
battery. Disconnect battery and ensure that 28 Volts can be measured on battery charger leads.
41B20.3 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.
Press watchdog reset. If system does not return to normal then the panel is probably damaged and needs
the circuit board replacing. (See maintenance section).
42B20.4 Aux 24V fault
The Aux 24V and R0V terminals provide a 500 milliamp, 24V DC power supply for power fire alarm ancillary
equipment. This LED indicates that fuse protecting the R0V 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.
43B20.5 Batt low
Illuminates when the system is running on batteries and the battery voltage is lower than 21V +/-2% (the
minimum battery voltage).
44B20.6 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.

Man-1078_Sigma_CP_22
Page 20 of 24
45B20.7 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.
46B20.8 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.
47B20.9 Comms fault
Indicates that communication has been lost with a repeater panel or Ancillary board. Check for comms fault
at all repeaters and ancillary boards to identify the source of the problem.
20B
