Notes on systeminstallation

The power-up of the control panel andcommissioning of the system is done by the

Servicing organisation.

Installation requirements

It is recommended that the installer follow the general requirements ofBS5839:Part 1, which is the code of practice relating to fire detection andalarm systems for buildings. The installer must follow the relevant partsof BS7671 : 1992 Requirements for Electrical installations, IEE wiring

regulations 16th edition if installation is in the United Kingdom, UK.

Second fix installation

To prevent the possibility of damage or dirt degrading the performance orappearance of the products, the installed products must be suitablyprotected until all major building work in the area is complete.

� The installation of all outstanding parts is usuallycarried out during commissioning of the system.

Fixture and fittings

It is the installer's responsibility to provide adequate fixtures and fittingsfor the type of construction surface onto which a product is to beinstalled, whilst utilising the fixing points on the respective product. As anaid to this decision, the weight and overall size of each full assemblytogether with implications on cable entries and routing should be takeninto consideration.

� All these procedures assume that the cable, gland,steel box (BESA box) and other related accessories are providedby the installer.

As fitted drawings

The installer should acquire site specific information from the interestedparties, for details on the location of products for installation. Theacquired information together with this guide and the relevant standardsshould be used to assist the work.

Each product assembly can be identified from its package label. Thecontents of all packages should be checked for any discrepancies.

Cable type and routing

Appropriate attention must be given to ensure correct cable type isinstalled in accordance with as fitted drawings, site specific informationand recommendations of BS5839 Part 1 : 2002. The cables must beinstalled using cable manufacturers recommended fixings andaccessories.

Fire sensor covers

Each fire sensor may be supplied with a plastic dust cover and can beordered separately. If supplied, the cover must be fitted to prevent dustand dirt from the building work contaminating the fire sensor.

Earth continuity

All earth connection points should be clean to provide a goodelectrical conductivity path. To maintain the earth continuity allearth leads and fittings provided should be installed. The loop cablescreen must be continued through each system device on the loopcircuit, whether the earth is connected to the device or not.

�Do not rely on any part of building structure for earthing.

Some of the system products having metal enclosures have a zinccoating around the cable termination points, the coating provide a goodelectrical conductivity path for cable earth termination.

The zinc coating on the metal enclosures should not be damaged. Anydamage will expose bare metal, which can corrode and make a poorearth connection.

Mains supply

Mains supply to any fire alarm control and indicating equipment must bevia an unswitched 5A fused spur unit. A 'disconnect device' must beprovided to disconnect both poles and must have a minimum gap of3mm. The 'disconnect device' should be available as part of the buildinginstallation and must be easily accessible after installation is complete.

�All mains powered equipment must be earthed.

Local Manual Call Point

To comply with the requirements of EN54 : Part 2 : 1997 a conventionalmanual call point must be installed near the main control panel. The callpoint must be wired to an input line of an interface unit on the loop circuit.During commissioning call point input must be set up to evacuate allsectors without delay.

� Failure to install and configure a local manual callpoint in the manner described above when delays are set up onthe system will result in the panel not complying toEN54 : Part 2 : 1997.

EN54 informationOptional functions with requirements of this European standard

The Control panel complies with the requirements of EN54 : Part 2 : 1997. In addition to the basic requirements of the standard the panel conformsto the following optional clauses:

Clause Description

7.8 Output to fire alarm devices

7.11 Delays to action outputs

8.3 Fault signals from point

9.5 Disablement of each addressable point

10 Test condition

System wiring

�If instructed by the project, the installer may need to terminate as well as connect the cables to the appropriate terminal blocks.

Cable separationWhere the outgoing and return cables of a loop which covers more than the equivalent of one zone they must not run together, for example, eitherclose to the Control Panel or in a service duct. There should be as much physical separation as possible between the cables and the mechanicalprotection of the cable should be to a particularly high standard. This is to minimise the risk of accidental damage to both cables. There should beseparation from the mains supply cable.

Lightning protectionWhere a loop cable or network cable is to be mounted to an external wall or between two buildings then consideration should be given to the use oflightning protection devices.

Requirements of cables

The British Standard BS5839 Part 1 : 2002 Code of practice for systemdesign, installation, commissioning and maintenance states therequirements for standard and fire-resisting cables in Clause 26.2 sectiond and e.

d) Standard fire-resisting cables should meet PH 30 classificationwhen tested in accordance with EN50200 and maintain circuit integrity ifexposed to the following test:

- a sample of the cable is simultaneously exposed to flame at atemperature of 830ºC - 0+40ºC and mechanical shock for 15min,followed by simultaneous exposure to water spray and mechanical shockfor a further 15min.

e) Enhanced fire-resisting cables should meet the PH120 classificationwhen tested in accordance with EN 50200 and maintain circuit integrity ifexposed to the following test:

- a single sample of the cable is simultaneously exposed to flame at atemperature of 930ºC - 0+40ºC and mechanical shock for a period of60min, followed by simultaneous exposure to water spray andmechanical shock for a further 60min."

� The cables listed in this manual are those that havebeen tested for EMC compliance with the system products.

Loop Cable usage

� There is a maximum limit of 1Km loop cable usageallowed per loop circuit. This maximum limit is the sum of thecable used to wire the main loop circuit, the spurs off main loopcircuit, plus cables that run to all input / output lines off the looppowered interface units installed on the same loop.

There is a further maximum limit of 100m cable run allowed perinput / output line off loop powered interface unit.

Loop cable

The loop cable carries both data and power supply, therefore itsselection is important. Note the following:

� In countries where the European EMC directive is inforce, only EMC Compliant cables are to be used.

� The loop cable usage must not exceed 1Km. Thisincludes the cable usage on main loop, spur circuitsand interface lines.

� Single pair cable must be used. It is NOT permissible torun mixed loops or outgoing and return pairs in a multicore cable, due to inadequate separation and possibleelectrical interference problems.

� Each core of the loop cable must be 1.5mm2 crosssection area.

� the cable screens must be capable of being earthed ateach system device (outstation).

� Red is the preferred cover sheath for fire applications.

� The specified loop circuit cables are also suitable forwiring master alarm, auxiliary relay, input/output linesand mains supply.

Enhanced cables

� Mineral insulated cable (MICC) to BS6207:Part 1

� Approved Enhanced cable:Draka Firetuf Plus Enhanced FTPLUS2EH1.5RD

� Prysmian (formally Pirelli) FP PLUS *

Standard cables

Approved EMC cables for loop wiring

� Draka Firetuf EMC Standard 1.5mm2

� Huber & Suhner RADOX FR *

� Prysmian (formally Pirelli) FP200 FLEX *

� Prysmian (formally Pirelli) FP200 GOLD *

� The cables marked * utilise laminated aluminium tapewith a tinned drain wire for electrostatic screening. Under certainenvironmental conditions galvanic action may take placebetween the aluminium and the drain wire. This will severelydegrade EMC performance as the foil to drain wire impedancewill increase.Armoured variants of the cables marked * can also be used onloop circuit.

Mains Supply cable

The mains supply cable must be a standard fire-resisting type and shouldmeet PH30 classification, like the standard and enhanced cables listedabove.

6


Typical SENTRI4 system

The loops allow wiring of addressable devices like fire sensors, alarm sounders, call points, interface units, zonal mimic and repeat panels. Acombined maximum of up to 200 devices is allowed per loop circuit, a further limit on a loop circuit is determined by the load factor.

Devices per Device loop

� It is important that redundancy is built into the system to accommodate future expansions.

The number of devices on one loop circuit can be limited by the total number of addresses available, the electrical load on the circuit, the maximumcable length and other geographical considerations.

� A loop circuit must not cover more than 10,000m2 of floor area of a protected site.

� In total a maximum of 200 devices are allowed per loop circuit..

� As a general rule allow 1000 load factor per loop circuit.

� A maximum of 512 loop devices is allowed per panel.

The following table can be used as a rough guide only to determine the loop load.

� For a precise battery standby value use the Battery Standby Calculator. The Battery Standby Calculator tool should be usedduring system design stage to determine the loop loading. The tool can be downloaded from the SMS forum (www.smstoolbox.co.uk),which is accessible to registered users.

Information on minimum sound output levels to include polar dispersionis covered in a technical note TECH7018.033, available on request frommanufacturer.

Base

The base has terminals for external cables to allow it to be electricallyconnected to the panel loop circuit and to the monitored input or outputcircuit. Any SenTRI device can be plugged into an SenTRI base.

Base Gasket

The optional foam rubber base gasket S4-BASE-GASKET can be fittedto the base to prevent water damage from dripping water from theceiling.

Base labels

An optional label SEN-BASE-LABEL can be fitted to the base. The labelcan be marked up with device location information.

Indicators

The SenTRI has a red LED that gives an indication in the event of a fire.The LED can be configured to flash periodically, as an 'in operation'confirmation, this indication is given system-wide at all SenTRI device.

Dust Cover

A dust cover is supplied with the SenTRI, to prevent dust from buildingwork contaminating the sensor. The cover is removed prior to thecommissioning of the fire alarm system.

Do's and Don't

�DO NOT locate smoke detectors where products ofcombustion may be present such as kitchens, garages,furnace rooms, welding shops etc.

DO NOT locate heat detectors above boilers or heaters orwhere the temperature is normally very high or liable tosudden fluctuations.

DO NOT locate smoke or heat detectors: -• In dusty or dirty environment.• Near heating or air-conditioning grilles.• Outdoors in stables, sheds etc.• In excessively damp areas.• In dead air spaces at the junctions of

ceilings and walls.• At ceiling locations where a ‘thermal

barrier' may exist.Follow recommendations detailed in section 22of BS5839 : Part 1 : 2002.

Siting

A SenTRI device plugs into a dedicated Base that is installed in theprotected premises. The Bases should be sited in locations as defined bythe project plans and by BS5839 : Part 1 : 2002.

28


Metal back box

A metal back box must be used for base or semi-flush mounting. Theearth continuity must be maintained throughout the whole loop. The earthmust be securely connected to the back box.

In - Out wiring to SenTRI bases

Programmable input/output

All SenTRI devices can be configured as either monitored input orunmonitored output. The factory setting of the programmable input /output is unmonitored output, to drive an external repeat LED without aseries resistor. There is a maximum cable length limit of 15 metres fromthe SenTRI base to the external I/O Unit.

The input can accept signals such as fire, non fire or fault, these areconfigured during commissioning. As a fire input it is possible to connecta conventional Manual Call Point (non UK application only) with a seriesresistor of value 470 Ohms coupled with an end-of-line 10Kohmsresistor. In this case the fire input is fully monitored for open or shortcircuit faults.

The input can be setup as a non-fire or fault input using a similararrangement with series and parallel resistors as shown. It is possible forsuch an input to trigger a command that is configured to action an outputelsewhere in the system to control plant equipment such as theventilation system.

Tools for SenTRI devices

An extractor tool allows removal and fitting of the SenTRI device headinto the base. By fitting a screw-on adaptor, the tool can be used toremove the sensor dust cover.

To remove a SenTRI device

Fit the tool onto the SenTRI device. Turn SenTRI device anticlockwiseuntil it stops and remove the SenTRI device from the base.

To fit a SenTRI device

Fit the SenTRI device on to the tool. Offer SenTRI device to base androtate clockwise until it moves upwards on to the base and rotate it againuntil it clicks and goes no further, the lines on the base and SenTRIdevice will align.

To fit a dust cover

Place the dust cover onto the tool inside the cradle. Offer the cover to theSenTRI device, locate and push to fit it onto the assembly. Withdraw thetool when the dust cover is in place.

To remove a dust cover

A dust cover remover tool must be fitted to the main tool to extract thedust cover. Press the pad of the dust cover remover tool onto the dustcover, this creates an air tight grip, to allow the cover to be pulled offfrom the SenTRI device.

Mains Powered Interface(from Qtr 3 2010)

The Mains powered interface units (78302-02NM and 78302-12NM) areEN54-4 compliant battery backed power supplies that can be directlyconnected to the loop and also have highly flexible interfacing capability.

The 4 channels can be individually configured to provide Output andInput interface in various configuration modes, to control externalequipment and receive input to allow the fire system to make decisionsand take actions. It is now possible to have combined inputs and outputsgiving a total of 8 external circuits connected (e.g. 4 sector outputs and 4confirmation inputs). The units have room to accommodate optionalmodules on to DIN rails. It has a configurable auxiliary power output thatis derived from its self contained mains power supply unit, which isbattery backed to continue to deliver power in the event of mains supplyfailure.

Network wiring

� In countries where the European EMC directive is in force use only those cables that are EMC Compliant, see list under theheading Network cables.

The recommended cables used to interconnect control panels are listed in this section.

Network cable screen continuity

Ensure a good screen continuity joint exists where there is a split cable.

� DO NOT mix cables of different types on the same leg of a network, as this will create impedance imbalance anddisruption to data communication.

How to minimise cross talk

� When using standard MICC cable in a network the different legs of the cable must not be closely placed together,as this will cause signal crosstalk which results in communication failure.

There are three practical ways of overcoming the crosstalk problem:

� used a twisted-core MICC cable

� put a ferrous screen between the cables (ie in the two runs of steel conduit)

� maintain a distance between the network cables of at least 50mm

53


These split cables

MUST BE of the same type.

Domain Bridge across NetworksIt is possible to connect two or more SENTRI4 networks together by means of domain bridge. To domain bridge two or more networks a Domainbridge IO card must be installed in the bridging panel.

There are various methods of domain bridging depending on the distances between panels. Domain bridge can be made directly using RS232 portsof the IO card, via modem, RS422 converter unit, Fibre optics or via dedicated network using NPORT units.

Methods of domain bridging

� A domain bridge IO card is required to be installed in the bridging panel/node.
