1. 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.

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.

4. 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.

5. 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.


Page 8 of 22

6. 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 2.5mm

2

.

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.

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.

SOFTWARE VERSION LABEL


Page 9 of 22

8. 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.

9. Sounder circuit wiring

Whether using standard or T series control panels, all sounders must be of the polarised type. If nonpolarised 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.

10. 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.


Page 11 of 22

11. 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.

12. 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.

13. 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.


Page 12 of 22

For panels with software version Sigma242.hex or below, the Enable controls keyswitch and Write Enable switch must both be set to off.

14. 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.

15. 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.

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 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).

16.3 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.

16.4 Reset

To reset the panel, insert the Enable key then press the Reset button.

16.5 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.

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.

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.

16.8 System fault

The System Fault LED will light if the configuration memory has not been set or has become corrupt.

16.9 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.

16.10 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.

16.10.1 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


Page 14 of 22

Note: The flashing “dx” indicator will only appear on panels with software version sigma_CP 214.hex and higher produced after July 2012.

16.10.2 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.

16.10.3 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.

16.10.4 Disable fault contact

The fault relay can be disabled by selecting configuration option 22.

16.11 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.

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.

Figure 8 – Access level 3 (Write enable) enable switch location

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.

Page 17 of 22

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.

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 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.

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.

20. 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:

20.1 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.

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 battery. Disconnect 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.

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).

20.4 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.

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.


Page 18 of 22

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.

20.9 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.

21. Power supply

The control panel requires a 230V (+10%/-15%), 50/60Hz, AC mains power supply which connects to the fused terminal block labelled “230V”.

The fused terminal block contains a 20mm, F1.6A L250V fuse which should only be replaced with a similar type.

The output voltage of the power supply is 28V DC +/- 2V and the total current rating including a maximum

0.7A for battery charging is 3 Amps. Fuse F12 mounted on the circuit board is a self-resetting electronic fuse rated at 4 Amps.

The incoming mains cable should be routed well away from other lower voltage wiring by a distance of at least 50mm.

Mains wiring should include an earth conductor which is securely bonded to the building earth and should enter the enclosure as close as possible to the mains terminal block. Mains wires should be kept very short inside the enclosure and secured together close to the mains terminal block with a cable tie.

The control panel can accept sealed lead acid rechargeable batteries of up to 7Ah maximum capacity (see table 2 for battery size required for each model).

The maximum current drawn from the batteries when the main power source is disconnected is 3 Amps.

Battery leads are supplied wired to the PCB along with a link to connect the two batteries in series. The PCB is fitted with a 20mm, 3.15A T1 glass fuse (F13) in the battery charging circuit which must only be replaced with one of the same type.

It is most important that the polarity of the batteries is carefully observed when connecting.

When the batteries are discharged to a level at which a low battery indication is given, the BATT FAIL indicator will also be lit.

Wrongly connected batteries could cause damage to the control panel.

22. Maintenance

Sigma CP control panels do not require any specific maintenance but should the control panel become dirty it can be wiped over with a damp cloth and should then be dried with a dry, lint free cloth. Detergents or solvents should not be used to clean the panel and care must be taken that water does not enter the enclosure.

The control panel contains sealed lead acid batteries to provide standby power in the event of a mains failure.

These batteries have a life expectancy of around 4 years. It is recommended that these batteries be tested in accordance with the battery manufacturer’s recommendations annually to determine their suitability for continued standby applications.

Routine testing of the fire alarm system in accordance with BS5839: Part 1: 2002 will identify any malfunction of the control panel and any malfunction should be reported to the fire alarm maintenance company immediately.

Should the control panel become faulty the complete electronic assembly can be replaced.

To do this, any configured options should be noted then both mains and battery power should be removed before the work is started.

The field wiring should be carefully labelled and removed from the terminals.

The PCB can now be taken out of the panel by removing the 2 holding the plate in position.

Fitting the new PCB is the reverse of the procedure for removing the board.

23. Zone designation label

All Sigma CP control panels are supplied with a zone designation label onto which zone designations can be written.

This enables each zone to be given a text description allowing easier identification of any zones showing an abnormal condition.
