2 Programming the Detector

The FIRElink - 25 may be progr ammed from a PC when connected to the detect or v ia a standard 9-pin serial lead connected to the serial port of the computer and the 9 way socket at the base of the detector (see section 7. 4, ‘Connecting to a PC’). In order to do this, it is necessary to install the rem ote control software onto the c om puter. A copy of the remote control software is cont ained on a CD-ROM supplied with each detect or . Instal l the software in accordanc e with t he on-screen instructions. To open the sof tware , select Start > Programs > Ho chiki > Remote 3.0

The programmable functions are all accessed though the Options > Detector settings submenu or by clicking on t he detector button on remote software toolbar as i ndicated below:

The following screen is displayed:

This window contains all the programmabl e functions for the FIRElink-25. To amend one of t he programmable functions, go to the relevant tab, make the change and then clic k OK. This will save the change to the detec tor’s internal firmware.

A list and explanation of the various functi ons i s given below, with the functions grouped by t he tab under which they appear.

2.1 Time and Date tab

It is important that the time and date be set up correctly on the controller’s internal c alendar /clock because it uses this inf ormation to store events in the event log. See section 8, “Event log” for more details. Unl ess speci ally ordered, unit s are suppl ied with the correct sett ing for UK time. This is backed up with a rechargeabl e battery. Later adjustm ents to t he cl oc k sett ing should not exceed ± 70 minutes unless a FastLearn is initiated.

2.2 Alarm Levels and Delays Tab

2.2.1 Alarm Levels - (Level subgroup)

The value set in the Fir e, Pr e- Al arm and A ux functions in the Level subgroup is the rel atively scaled bargraph level at which the appropriate alarm is initiated on the detec tor. The Fire 2 level assigns an absolutely scaled alarm level in % obs/m.

The Aux level is set by factory default at level 10 which means that this alarm will occur after the Fi r e alarm. The def ault level settings for Pre-Alarm and Fire 1 are 6 and 8 respectively. The default setting for Fire 2 is 20% obs/m.

2.2.2 Alarm Delays - (Delay subgroup)

The alarm delay i s the number of seconds that an alarm level has to be continuously sensed before the alarm is initi ated. Each alarm level has a programmable delay of between 0 and 90 seconds. The default delay for each al arm level is 5 seconds.

2.2.3 ClassiFire® Override

This functi on has no curr ent use on the FIRElink-25 but is reserved for future expansion purposes.

2.2.4 Alarm Factor

The detector sensitivity is set with this entr y , which will also affect the probability of nuisance alarm s. 0 = high sensitiv ity, higher probability, 8 = low sensitivity, lower probability. The default alarm factor is 4.

Note: The highest sensitivity setting is suitable for clean, envir onm entally controlled envir onm ents, e.g.

semiconductor manufacturing clean r oom s where airbor ne pollutants are kept to an absolute minimum and the least cont am ination is cause for alarm.

Use of this setti ng in a busy mac hine shop would lead to relatively fr equent nuisance alarms due

to the normal vari ation of atmospheric contamination and a lower sensitivity setting is recommended. I t is therefore important that t he alarm factor chosen is suitable for the area to be protected. When t he appr opr iate alarm factor for the protected area has been set, nuisance alarms will be reduc ed to an absolute minimum.

The following table gives suggested settings of ClassiFire alarm setting for different locations:

Alarm Factor

0 Extremely High Once per year Semiconductor manufacturing clean r oom 1 Once per 5 years Computer room 2 Once per 10 years Non- smoking office 3 Once per 50 years Clean factory

2.2.5 LDD Enable

When this function is ticked, Laser Dust Discrimination (LDD™) increases the respon se time of the detector slightly, whilst greatly r educing the likelihood of nui sance alarms due to dust ingress. LDD may be disabled in v ery clean r oom s for a slightly faster response to sm ok e by setting this function to unti c ki ng the box. This function is enabl ed by default.

NOTE: Disabli ng LDD is not r ec ommended f or ar eas other t han m anufacturing clean room s, due to the

increased probability of nuisance al arms in most other operating envi r onm ents.

2.2.6 FastLearn Enable

If the detect or i s in FastLearn mode, unticking this box will st op the FastLearn process. Using the function in this way is neither r ec ommended nor support ed by Hochiki Europe (UK ) Limit ed.

Ticking the box will star t a FastLearn at any time. The green “OK ” LED on t he front of the det ec tor will flash for the fift een mi nutes that it takes for the FastLear n process, and will then c hange to constant illumination to indicate that the FastLearn is complete.

Note: It will tak e a further 24 hours after the FastLearn for full sensit ivity to be reached, unless

Demonstration Mode has been initiated (See sect ion 3.10, “Demo mode”). It is essential for proper functioni ng that the detector not be left i n Demonstrat ion mode, and that it be allowed to complete the 24-hour lear ning period. To cancel demo mode, tick this box or power down and restart the detector t o initiate FastLearn mode.

2.2.7 Auto FastLearn Enable

When enabled, this function ensures that if the detector is powered off for any reason (e.g. for maintenance or to be mov ed to a new area), a FastLear n is commenced automatically on power-up.

There may be occasions when it is desir able to power down the detect or for short periods of time, and it is highly likely that ambient contaminant levels will be the same on power-up. Under t hese circumstances it may not be desirabl e that the det ec tor should to go through the whole lear ning process again. To this end, this function can be unticked before power-down, where upon it will retur n to the original settings on power-up. This function is enabled by default.

2.2.8 ClassiFire 3D

If this function is ticked, then the detect or will ignor e any pr e-set time delays in the ev ent of an unacceptably r apid increase in smoke densit y, thereby mi nimising response time to 'rapid growth' fires. This functi on would normally only be used where there were long t ime delays programmed on t he alarm levels. This function is disabled by default.

2.2.9 Demo Mode

Demonstration mode is an operating mode whereby the normal 24-hour learning period is bypassed, so that the detect or can reach high sensitivity aft er only the 15 minute FastLearn period. This can be used so that initial smoke testing and other commissioning can be carried out.

However, it must be understood that, since the alarm levels will be based solely upon the sparse data gathered during the FastLearn period, there is a risk of nuisance alarms due to normal variations in ambient smoke levels. For this reason, the detector should not be left in Demo mode for normal use when connected to a fire panel.

2.3 Day/Night Switching Tab

2.3.1 Day Start / Night Start –

These values are t he times to the nearest hour at which the day/ night switching is desired to take place on the detector . Entries are made in 24-hour format, e.g. 19 for 7pm. Day and night switching is i ntended so that the detector may automatically select a different sensitivit y when the pr otected area is unoccupied and fewer contaminants are being produced. ClassiF ire automatically detects the change in smok e lev el after the protec ted area is left, and if the time at which this happens is within + 70 minutes of the programmed switc hover time it selects the night-time histogram. This means that changes i n time setting, for example changing to summer time, may be ignored as the detect or wi ll take this into account . The default times for day and night start are 08:00 and 19:00 respectively.

NOTE: That if the envir onm ent actually becomes more contami nated during the night period for any

reason then ClassiF ire will adapt to that too, reduc ing the night-time sensitiv ity.

2.3.2 Disable Day / Night Switching

If day/night switching is not desirable, the Disable day/night switching box may be ticked to leave the detector perm anently in day mode.

2.4 Alarm Actions Tab

2.4.1 Remote Functions (Remote Input subgroup)

These functi ons have no current use on the FIRElink-25 but are r eserved for future expansion purpose s.

2.4.2 Programmed Isolate

When this function is ticked the controller will not generate alarms and will not indicate a fault conditi on on any fire panel whic h is connected, e.g. for use during detect or m aintenance. The “Fault” light will be illuminated on the detector front panel. The isolated condition will be disabled automatic ally after 7 days if not manually disabl ed. This function is disabl ed by default.

2.4.3 Latching Alarms

When this function box is tic k ed it requires a reset from the controlling computer to clear an al arm condition. If unticked, the alarm signal is exti nguished as soon as the alarm condition ends. This is the factory default setting.

2.4.4 Latching Faults

When this function box is tic k ed it requires a reset from the controlling computer to clear a fault condition. If untick ed, t he fault si gnal is extinguished as soon as the faul t condition ends. This is the factory default setting.

2.4.5 Cascading Alarms

Ticking this function box means that only when the detector ’s cont roller has gone into P r e-Alarm does the controller star t counting down the main Fire delay i.e. the time delays on Pre-Alarm and Fire 1 are cumulativ e. T he Aux alarm is not incl uded in the cumulative delay si nc e it may be set to a higher level than either the P r e-Alarm or Fire 1 levels. This functi on is enabl ed by default.

2.5 Device Information Tab

2.5.1 Device Type

This functi on is for displ ay pur poses only. It shows any special desi gnation for the unit, whic h will normally be FIRElink-25.

2.5.2 Firmware Version

This functi on is for displ ay pur poses only . It shows the version number of t he fitted firmware chip.

2.5.3 Run-time Hours

This functi on is for displ ay pur poses only . It shows the cumulativ e tot al num ber of hours t hat the device has run (this is not t he time that has el apsed sinc e last power-up, but the sum t otal of r un time si nce the detector memory was last reset).

2.5.4 Watchdog Count

The watchdog is a circuit built into the controller that restarts the controll er in the event of a failure to function properly. This could be as a result of electri c al spikes. This count shows the number of interruptions found. The details of each problem can be found in the event log. See section 6, “Event Log” for further details.

2.5.5 Device Text

This functi on has no curr ent use on the FIRElink-25 but is reserved for future expansion purposes.

2.6 Referencing Tab

2.6.1 Reference Detector

A FIRElink detector may use another detector as a fresh air reference. This function is the address of the detector which will be used as the reference. To set a detector as a ref er enc e detector, enter its address as set by its inter nal DIP switc h i nto this function. This function is disabled by default.

2.6.2 Reference Enable

Ticking this box enables the reference for the detector, if one has previ ousl y been allocated in Reference detector (see section 2.6.1). This function is disabled by default.

2.6.3 Reference Level

The value set wit h this function is the percentage ref er ence signal subtracted fr om the detector’s signal, if a reference device has been allocated. The default v alue is 0.

2.6.4 Reference Back-off

This value is the delay time between a build up of pollution bei ng seen by t he r efer enc e (if used) and the pollution bei ng seen by t he detector. The default v alue is 15.

2.7 Flow Monitoring Tab

2.7.1 Flow Rate

This functi on is for displ ay pur poses only , and shows a value correspondi ng to the current airfl ow through the detector .

2.7.2 Flow High Limit

This value is the lev el abov e whic h airflow needs to increase to tri gger a fault indication (which may indicate a loose or damaged inlet pipe). Flow low limit and Flow high limit parameters are autom atically set up on initial power-up.

2.7.3 Flow Low Limi t

This value is the lev el below whic h airflow needs to be reduced to t ri gger a fault reading (which may indicate a block ed pipe). Flow low limit and Flow high limit param eters are automatically set up on initial power-up

2.7.4 Flow Fault Delay

This featur e requi r es the Rem ote Control Software version 3.2 or later, availabl e from the Hoc hiki E ur ope Technical S uppor t Department (psupport@hochikieurope.com) .

The default flow fault thresholds on the FIRElink-25 are set to meet the stringent airf low monitoring requirement s of E N54- 20, with a default flow fault delay of 30 seconds. This may lead to unwanted flow faults bei ng gener ated when local conditions cause short-term variations i n airflow. To help alleviate such issues, the flow fault delay is programm able from 30 to 240 seconds. T he flow level needs to be above the high flow threshol d or below the low flow threshold throughout t he delay period for a fault to be generated.

NOTE: When setti ng the value of this function, it is important to take into account that the contr ol unit (for

example, fire panel) may not react immediately to a trouble signal being generat ed by the detector, and this will add to the total fault response tim e of the system.

The function v alue m ust be c hosen so that the total time between the detect or entering a fault condition and a fault signal being gener ated by the panel meets the requirements of local or national fir e regulations. The maximum allowable response time for EN54-20 compliance is 300 seconds, and that for NFPA 72 compliance is 200 seconds.

As an example: in the latter case, if the flow fault delay were set to 180 seconds (within the limi t), but the fire panel did not gener ate a fault indication for another 25 seconds, t he total response time of 205 seconds means the system would not comply with the regulat ions.

If documented figures are unavailable for the fire panel reaction time, compliance with reaction time regulati ons may only be v erified by post-installation testing.

2.8 Miscellaneous Tab

2.8.1 Access Code

This is the access code required to amend programmable param eters. The default code is 0102. Once the appropriate code is entered it may be changed here to any four digit number to limit unauthorised access.

2.8.3 Separator Condition

The value given at t his func tion is the efficiency rati ng of t he dust separat or element in the detector as a percentage of t he eff ic iency of a clean separator. A new element will give a reading of 99 in this functi on. When the efficiency has decreased to 80%, the Fault i ndic ator LED will illuminate and the ev ent log will show “Separator rene w”.

NOTE: Fitting a new elem ent will reset this figure to 99

2.8.4 Separator Change Date

This function defaults to “--“, which means that a separator fault will only appear when the efficiency decreases to 80% (see 2.8.3, “ S epar ator Condition” ). However, a date may be enter ed into this function

The detector will then generate a separator f ault at the planned tim e regardless of the condition of the separator , although degradati on of the separator to below 80% efficiency before this date will override this. See section 8, “Maint enanc e” for further details.

2.8.5 Factory Default

Enabling this function will reset each programmable function to the default value indicated in the text, where a default setting is specified. It will also put the detector into FastLearn mode, regardless of whether or not Auto F astlear n is enabled (see section 2.2.7) . This ensures that the flow setups and alarm thresholds are optimised to the detector’s working environment after resetting. It should be noted that where a ClassiFi r e alarm f actor other than the default i s requir ed for the protected area, this will need to be re-entered. S ection 2.2.4 gives details of the ClassiFire alarm factor s.

2.9 Other Remote Softw are Features

2.9.1 Reset

If latching alarms (see section 2.4.3) or l atching faults (see section 2.4.4) are enabled, the relevant alarm or fault warnings will remain on the detector front panel LEDs and controlling unit unti l a r eset is performed. If using SenseNET software, indiv idual detectors can be reset (refer to the SenseNET User Guide for details). In the remote software, a global r eset is available which resets all detectors on the SenseNET loop, or a singl e stand- alone detector.

To perform a reset, either select the menu options Options > Global Reset or click the button on the toolbar as indic ated below:

2.9.2 Histogram Screen

The histogram screen sho ws various aspects of the detect or function. To enter the histogram screen, either selec t t he m enu options View > Histogram Viewer, or click the but ton on the toolbar as indicated below:

The following screen is displayed:

Smoke Density histogr am Alarm flags

There are two types of sm ok e density hi stogr am ; one shown in blue (the “fast” histogram) which updates every 15 minutes, f eeding information to the long-term “slow” histogram s (whic h appear in yellow). These set the detector sensit ivity based on the ambient sm oke conditions and it takes 24 hours f or the two slo w histogram s (t he “ day ” and the “ night” histograms) to com plete their learning phase (see section 2.2.6).

Detector sensitivity is based on the fast histogram during FastLearn and is ther eafter based on the currentl y active slow histogram. However, although the positions of the al arm fl ags are based on the sl ow histogram, sudden changes in smoke densit y are pick ed up by the fast histogram so that early warning is given.

Sensitivity: The current absolute sensitivity of the detector in perc entage obscuration per m etre ( %

obs/m)

Mean: The current mean value of smoke density, taken from the currently “active” hi stogr am and given

as a percentage of full scale deflection.

Variance: The “spread” of data in the currently “active” histogram and given as a percentage of full scale

deflecti on.

FastLearn: If the detector is currently in FastLearn mode, this will show the number of minutes

remaini ng in the FastLearn period. When thi s period has elapsed i t will read “OFF”.

Alarm factor: This is the ClassiFire alarm factor (see section 3.5, “Alarm factor”) Day/night: This indi c ates the cur r ently active slow histogram Alarm leve ls: These fi gur es give the position of the various alarm flags in terms of a percentage of full

scale deflec tion.

Detector output: This shows the real-t im e variation in background smoke levels in terms of a

percentage of f ull scale deflection.

3 Design Limitations

FIRElink-25 is i ntended to provide LOCALISE D incipient fire detection only. This means that it is suitable for the substantial range of applications typified by; small non-compartmentalised rooms, warehouse rac k ing, or pieces of electronic or electrom ec hanic al equipment where it is desirabl e to achieve individual incipient fire reporting. In compartmentalised room s, eac h c om partment would normally use individual FIRElink-25 detector s.

This product em ploy s a very low-power aspirator and the aspirating capability of the FIREli nk - 25 detector is limited accordingly. FIRElink-25 i s NOT intended t o protec t large areas, or to sampl e from areas where there may be any differ enc e in airflow rates or pressure differentials. Appli c ation of FIRElink-25 in these circumstanc es i s not r ec ommended. If detection in environments conforming t o these descri ptions is required, alternative versions of FI RElink products should be used.

Maximum recomm ended sampling pipe length is 50 metres in STI LL AIR. I n ar eas or applications where the external airflow rate is greater than 1 met r e per second, t he maximum sampling pipe lengt h is reduced to 25 metr es.

Although by no means essential, it must be recomm ended that if in doubt, PipeCAD® be used to ensure that transi t times, balance of suction and individual sampling point sensit ivity are within desir ed limi ts.

Sampling pipes must have capped ends. The end cap should be drilled with a hole normally bet ween 4 or 5mm diameter and free from bur rs. Sampling holes should normally be 3-4mm diameter or as calculated by Pi peCA D, and f r ee from burrs. Each pipe run should not have more than 10 holes (including the end cap hole). Pipe transit time from the furthest sampling hole from the detector must not exceed 120 seconds and an approved type of pipe must be used for installations conforming to LPCB requirement s. It is strongly recommended that the sm oke t r ansi t time from the furthest sampli ng hole be checked during c ommissioning tests. Capill ar y Rem ote Sampli ng P oints may be used in place of sampling holes.

FIRElink-25 is supplied with a ‘Piped Exhaust’ t y pe Docking Station (see illustration A). This is primaril y intended to allow the F IRElink-25 detector t o sample from areas which may be at diff erent air pr essure to the detector loc ation. Typical uses are for air-duct sampl ing and allowing the installation of the detector in under-floor or ceili ng v oids or when sampling from pieces of c om puter related equipment.

3.1 System Design

Simple designs with short sampling pipes produce the best results. Complex sampling pipe runs should be avoided with the FIRElink-25 detector. The use of ‘T’ br anc h- pipes is not recommended. To assist in design and to verify system performance, it is advi sabl e to use the FIREl ink PipeCAD® sampling pipe modelling software.

Always locate t he sampling points in positions to whic h smoke m ay reasonably be expected to travel. Do not expect ceiling mounted sampling point s to oper ate satisfactorily if air fl ow fr om air - c onditioning systems keeps the cool smoke from an incipient fir e reaching from reaching ceili ng level. In this instance it is usually better to locate the sampling pi pe dir ectly in the airflow (for exam pl e ac r oss the ret ur n air register of an air condi tioning unit).

There is no substitute for carrying out smoke tests pri or t o installation of pipe work to indicate suitable sampling point loc ation.

No more than ONE Air Handling Unit m ay be prot ec ted with one FIRElink-25 detector. In this application, ensure that the sampling pipe is raised clear of high veloc ity air in the immediat e vicinity of the air intake grille on stand-off posts as shown below:

9-5-0-344/ISS4/OCT10

3.2 EN54-20 Compliance

The installation must be designed using PipeCAD soft ware, whic h is provided free on the CD shipped with each detect or . Aft er designing the installati on inc luding pipes, endcaps and sampling holes, enter the detector type in the “Type” drop-down list in “Options” “ Calculation options”.

Select “Options” “Calculate” or clic k on the c alc ulator icon. The software will pr om pt you to choose from “Use set hole sizes” “B est flow balance” and “Max. permi ssible transit time”. Sel ect the appropr iate option and click “OK”. The resul ts for each pipe (“View” “Results”) show calculations for each sampling hole on the pipe with the nearest to the detector at the top of the screen, and t he endc ap hole at the bottom.

“Transit time” shows the smoke transit time to the detector from each sampling hole. For EN54-20, t his must be below 120 seconds from ev er y hol e. The column headed “Hole sensitiv ity % obs/m” shows the predicted sensit ivity for each hole. For the instal lation to comply with EN54-20, each sampling hole must be no less sensitive than 0.31% obs/m.*

The calculation can be further refined by leaving a working detector in the protected area for at least 24hrs at the int ended alarm factor for the installation (this could be done befor e or after installation). The detector sensitivity can be read from the “Sensi tivity” figure on the histogram screen of the Remote software supplied with each detector. Enter this figure into the PipeCAD calculation under “Options” “Calculation options”, “Detector sensitivity”. Clicking on “ OK” will update the hole sensitivities to the figure expected for the actual layout.

Commissioning and per iodic system tests must inv olv e smok e tests to verify that the system performs as expected and ent ers Fire 1 alarm within 120 seconds from the f arthest hole. The detector sensitiv ity must also be inspected to ensure it has not radically f allen from the installed figur e. If it has changed for any reason. the new fi gur e m ust be re-ent er ed into PipeCAD and the recalcul ated hole sensitiviti es must be confirm ed to be wit hin the class lim its shown above. The settings of a c om pliant system should be recorded, as it is possible by c hanging certain programmable functions to make the system non-

9-5-0-344/ISS4/OCT10

FIRElink-25 – Installation Manual Page 23 of 40

compliant. If functions are changed, it is recommended that the system is retested if c ontinuing compliance is in any doubt.

*The results s hould be v er ified at installation by entering the installed detec tor's Fire 1 sensitivit y ( as indicated in the remote software histogram screen) into the PipeCAD “Options/Calculation options/Detector sensitivity” field and r ec alc ulating the layout res ults.

4 Installation

Before installing the detector the local standards for installati on of aspir ating detection systems must be consulted as these standards differ throughout the world. Specific advice for one country may not be applicable t o another. The following is a brief set of guidelines on installing detectors:

 The detector will normally be mounted at a level where there is easy access to the unit for

configuration and programming.

 The exhaust air from the unit m ust not be im peded in any way. If the unit is mounted in a different

air pressure fr om where the ai r i s bei ng sampled (for example an air duct), then a pipe must be taken from the exhaust por t back to the same air pressure zone as the sampling holes.

 Sampling holes should be free from burrs and swarf.  All signal cables must be screened and must be of a suitable t y pe. T he specif ic type of cable will

normally depend upon t he local fire regulations.

 The unit must not be plac ed in ar eas where eit her the temperature or humidity is outside the

specified oper ating range.

 The unit should not be plac ed in cl ose proxim ity to any equipment expected to generate high Radio

Frequency l ev els (such as radio alarms) or units generating high levels of electrical energy (such as large elect ri c mot or s or generators).

 In order for the installation to conform to EN54- 20, pipes must conform at least to EN61386-1 Class

4.1 Docking Station

The basic principle behind installati on of t he FIRElink-25 is that all wiring and pipe-work is install ed using a docking station. This is a convenient featur e which means that the detector can be dismounted or replaced without disturbing any wiring or installed pipe-work.

9-5-0-344/ISS4/OCT10

FIRElink-25 – Installation Manual Page 25 of 40

Piped Exhaust Docki ng S tation

4.1.1 Mechanical Installation

The docking station is connected to the installed sampling pipe-work and fixed to the wall or mounting surface using 3 off screws of a type appropriate to the m ounting surface. Ensure that t he sampling and/or exhaust pipes are securely seated in the pipe ports befor e fixing. If using a piped exhaust doc k ing station be sure that the sampling and ex haust pipes are fitted into t he r elev ant ports as shown in section 4.1.

4.1.2 Electrical Installation

The FIRElink - 25 detector is supplied with rem ov able termi nal blocks (See illustrations in Section 0). These are simply r em ov ed from their sock ets by lifting them up at right angl es t o the circuit board. Take note of the orientation of each terminal block and its f unction before removing it. It m ay also be benefi ci al to mark the connecti on wir es with suitable identification labels or colour ed ri ngs to aid in the connection process.

NOTE: All connections should be made with the power turned off.

4.1.3 Power Supply Connections

The power supply cable should be of screened type and should be l ed through the metal cable gl and provided, leav ing about 35mm of the cable extendi ng from the bott om of t he c abl e gland. Depending on the type of cabl e used, it may be necessary to increase the diameter of the cable with sleevi ng or insulating tape to ensure that the cable is fi rmly held when the cable gland is fully tightened.

Remove the detector cover by unfastening the four screws at the front of the unit and det ac h the power supply terminal block. This is at the top left with t he detector held with the seri al port at the bottom of the unit.

NOTE: Be aware of the ori entati on of the terminal block. Connect 0V and +24VDC to the “0V” and “ 24V ” screw terminals respectiv el y . Connect the screen wire to

the earth stud on the doc ki ng station and connect a second wire from t he “Earth” terminal to the docking station eart h stud. The picture in Section 4.1 shows the l oc ation of the earth stud. Fix the earth wir es i n place with the nuts provided.

4.1.4 Signal Connections

To connect the signal wire, lead a suitable wire ty pe ( RS485

cable 9841, 120 ohm screened twisted pair or equivalent)

through the second cabl e gland and tighten it into posi tion wit h

about 35mm of cable from the bot tom of the cable gland.

Remove either the three-way terminal block nex t t o the power

supply socket if connec ting the detector to a SenseNET

system, or the four - way “Bus” t erminal block if connecting t he

detector to an al arm panel in conjunction with the FIREli nk -

APIC addressable programmable interf ac e c ar d (see section

5.3).

For example, in a SenseNET system using screened cable

connect the screen wire( s) t o the “SCN” terminal, Bus A wire(s)

to the “A” terminal and B us B wire(s) to the “B” terminal. If the

detector is in the middle of a SenseNET chain, with input and

output connections, it may be more convenient to link the

common Bus A, Bus B and screen wires to singl e A , B and

screen wires for linki ng to the terminal block.

4.2 Final installation

Once the power and signal c onnec tions are made slide the detector body up into the docking stati on and fasten it into position using the M4 pan head screws provi ded. Slot the power and signal terminal blocks into the rel ev ant socket s on the detector PCB (they will only cli c k fully home in the correct orient ation) and replace the detector cover using the four M3 pan head screws provided.

NOTE: The detect or i s designed solely for operation with the front cover securely fitted using all four fixing

screws.

Removing the detector is simply the reverse of this proces s, leaving the pipe-work and wiring connections installed in the docking station.

5 Interfacing

Because of the flexible nature of the FIREli nk - 25 detector and the many possible confi gur ations, there are many options for interfacing the detectors to the Fire Panel. These include many third party interfaces available from v ari ous manufacturers. Because of this, it is not possible to give a complete list of all interfacing methods but the following pages wil l give details of the most common m ethods that are likely to be used.

5.1 Setti ng the Detector Address

In order to identify itself to the PC Command Module or fire panel, each detector needs to have a unique address ranging from 1 to 127. The detector address is simply set on the red DIP switch SW1 at the top left of the opened detec tor on the main circuit board. The switch settings are on for 1 and off for 0, and the detector addr ess is set as a 7-bit binary code (switch 8 equates to a v alue of 128 and so is outside the usable address range). A n ex am ple is shown below.

The address equates to 01100011 in binary, or (1 x 1) + (1 x 2) + (0 x 4) + (0 x 8) + (0 x 16) + (1 x 32) + (1 x 64) + (0 x 128) = 99.

The full range of av ailable addresses and their relevant switch settings are shown belo w:

9-5-0-344/ISS4/OCT10

FIRElink-25 – Installation Manual Page 29 of 40

5.2 Connectin g a FIRElink-25 to a SenseNET/RS485 Detector

Network

Up to 127 detector s may be link ed in a si ngle S enseNET bus, supporting a tot al length of wire between adjacent detectors of up to 1.2km.

In the above example, two FIRElink-25 detect or s are linked i nto a 127-detector bus with a Command Module and a number of other FI REli nk detectors. It will be noted that whereas the FI RE link-400 units have two input / output buses (1A / 1B and 2A / 2B), the FIRElink-25 has only a single such bus (A / B) and therefore each bus terminal has an input and an output wir e, compared with a single wire i n each terminal in the FIRElink-400.

For this reason, it may be easi er to join the input and output wires f or each bus and screen connect ions together and to sol der or crimp a si ngle wi r e or connect ing ferrule to each wire pair so that they are easier to fit into the screw termi nals. If this is done it is recommended t hat bare wir e joints be insulated to prevent possible shorting of the data bus, which will cause a drop-out of data on the SenseNET bus.

In the above example, there could be a total length of RS485 cable of up to 1.2km between the Command Module and Det ector 3, sinc e these are all on a single bus. However, Detec tor 3 is a FIRElink-400 whic h has a second communications bus (RS485 bus 2) and an RS485 repeater. This allows a further total of 1.2km of cable until the next FIRElink-400 in the RS485 loop.

In the above example, if detectors 4-126 (not shown) were all of t he FI REli nk - 25 type then the total length of wiring bet ween detectors 3 and 127 would be limited to 1.2km. However, each additional FIRElink-400 detector wired up usi ng both RS485 buses would allow an additional 1.2km of cabling to be added to the RS485 loop.

5.3 Connecting a FIRElink-25 to an addressable Fire Panel

An Addressable Progr ammable Interf ace Card (FI REli nk-A P IC) may be used to decode detector information and to relay this to a Fire Panel.

The FIRElink -APIC is fitted to the four mounting studs on the FIREl ink-25 PCB using the supplied screws as shown below:

Interface

Connection

The connections to the Fire Panel are made using the BUS L1 and H1 (bus 1 input and out put) and the BUS L2 and H2 (bus 1 input and output) termi nal c onnec tors shown in Secti on 4.1. 4.

The only setti ngs that need to be made are on the FIRElink-APIC address DIP switches. The start loop address Is entered on SW1 and the end loop address on SW2. In the case of a single FIREli nk - 25 the start and end addresses will be the same.

NOTE: The detect or address on the S enseNET loop and the Fire Panel addressable protocol address are

the same, in other words, no addre ss translation is performed. Some protocols may not support all the available alarm levels and fault repor ting is usually a general fault wit h no detailed fault information. Please consult the specifi c FIREl ink-APIC documentati on for more information.

5.4 Connectin g to a PC

To connect a single stand- alone detector to a PC, connect the PC‘s serial port directly to the detector‘s 9way RS232 port, which i s sit uated on the bottom surface of t he detector case. Connections for this cable are shown below:

6 Event Log

An event is defined as

 a change to any programm ed function  a signal received from an external controller such as the r em ote software, FIREli nk - API C or

SenseNET

 a detector out put level meeting or exceeding the P r e-Alarm , Aux, Fire 1 or Fire 2 alarm thresholds  a fault condition such as a flow or separator fault  start of day / night oper ation  demonstration mode start / stop  FastLearn start / stop  Power on or off

The detector stores an internal log of the last 200 events, and t his can either be viewed on a PC screen or downloaded to disk by use of the remote control software.

When the event log is full ( 200 ev ents are stored) and a new event occurs, the ol dest ev ent in the log is deleted (Fi r st- In, First-Out).

To download the ev ent log, c onnec t a PC to the detec tor serial port and run the remot e software. Either select the menu options View > Event Log or click on the event log sym bol as i ndi c ated below:

The following screen will be displayed:

This shows the time and date of each event stored in the log along with it s general description. The buttons at the bot tom of the screen allow control ov er the input and output of the log.

9-5-0-344/ISS4/OCT10

FIRElink-25 – Installation Manual Page 33 of 40

Open: opens a previously saved event log. Event logs have t he file extension “.evl”. Save As: saves the current event log as a .evl file with a user defined name. Print: prints the ev ent log to a connected printer. Filter: clicking on this option displays the f ollowing screen:

This allows the user to lim it the information printed or viewed on the PC screen. For example the user might wish to concentr ate on alarm events only. To do this, clic k on “None”, whic h unticks all boxes, and then click on “Alarms”. To tick all the boxes, tick “All ”.

Any or all of the event categor ies may be selected or deselected as desir ed.

7 Commissioning

Before commissioning the detector t he loc al standar ds of aspi rating detection systems must be consulted. These standards differ widely throughout the world and specific advice f or the m arket in one c ountry may not be applicabl e to another.

Commissioning str ategy will initially depend upon the environm ent in which the detector is instal led. For instance, t he test f or a comput er r oom (whic h shoul d be a r elatively clean env ir onm ent) would be very different f rom, say, a flour mill, which would probably have a high level of airborne particulate content .

A widely accepted standard for computer rooms/EDP areas is British Standard BS6266, equipment overheating at a stage well before combustion. To perform the test electrically overload a 1 metre lengt h of PVC insulated wir e of 10/ 0.1mm gauge for one minute using an appropriate power supply. The detector has two minutes from the end of the wire burn to giv e an alarm indication.

For areas with higher lev els of background particulate matter testing methodol ogy would be similar to that of standard point detectors.

7.1 Commissioning Checklist

The following bri ef checklist allows quick setup of the detector. This procedure wi ll be adequate for most standard installations.

1. Before powering up the detector, visually check all cabling to ensure correct c onnec tion. If wire identification is not immediatel y clear (for example, by use of different c olour ed wir es or wire identification sleeves) an elect rical check should be made. Any damage caused by misconnection of the detector is not c ov er ed by warranty .

2. Power up the unit and connec t t o a PC and set the address swit c hes on the detector board (see section 5.1) and FI REli nk - A PIC boar d if applicable (see secti on 5.3).

3. Verify that t he time and date are correct (see section 2.1)

4. Set an appropri ate alarm factor for the protect ed env ir onm ent. The detector will perform a FastLearn for the new alarm factor. (see section 2.2.6)

5. Whilst the detector is still in FastLearn mode set the detector into demonstration mode (see section

3.10).

NOTE: Aerosol- type synt hetic smoke sources should not be used to test the response of the detector as

these may leave acidic r esi dues which could cause damage to the unit.

6. Wait for the FastLearn t o finish and the flashing OK LED indicat or will finish and perform any necessary smoke tests, ensuring that the detector reacts appropriat ely (within 120 seconds f or LPCB compliance), and let the smoke fully dissipate.

7. Perform anot her FastLearn, this time not putting the detector into demonstr ation mode. The detector will generate no alarms during the 15 minute FastLearn per iod, and after thi s the detector will operate at a reduced sensitivity for 24 hours whilst ClassiFire acclimatises to t he pr otected environment and sets up appropriat e day and night sensitivity settings.

8 Maintenance

FIRElink-25 is a very low maintenance detection system. If required, ext er nal cl eaning of the unit should be perform ed using a damp (not wet) cloth. Do not use solvents as these may mar the f r ont panel label. The only part that m ay require field replacement during servicing is the dust separator assembly. The dust separator condition can be checked usi ng the Dust Separ ator test in the Miscellaneous tab of the remote software ‘Detector settings’ screen (see sect ion 2.8.3) whic h giv es a percentage reading of dust separator efficiency. When this level drops to 80% the detector will si gnal a fault and the dust separator will need replaci ng. To replace the filter, simply r emove the front cover and pull t he filt er out f r om the main unit. Slide t he repl ac em ent fil ter in so that the ‘Direction of fl ow’ arrow pri nted on the carton duplicat es t hat on t he ‘Dir ec tion of flow’ label beside t he filt er sl ot.

As dust contained i n the dust separator s may expose maintenanc e per sonnel to a ‘Nuisance Dust‘ hazard as defined by the ‘Cont r ol of Substanc es Hazardous to Health‘ (C OSHH) , it is strongly recommended that suitable masks and protec tive clothi ng be worn when changing f ilters.

intended for re-use and should be disposed of.

8.1 Diagnostics

The remote control software includes a diagnostic function which car ri es out a num ber of checks to verify the correct func tioning of the detector. A good tim e to run these tests i s a s a part of planned maintenance. To call up diagnostic mode, select t he menu options View > Diagnostics or cli c k on the symbol indicated below:

Click on the list entry to highlight it and click on t he Diagnostics button. The software will t hen commence the system t ests. During the “Aspirator and flow” test, the detector fan will suddenly sl ow down, but this is a normal par t of the t est.

When the test has finished and no problems have been found, the following screen is displ ay ed:

If any problems were f ound dur ing the diagnostic tests, the nat ur e of the fault will be indicated in the “Status” column.

Scan: Reads in the status of all connected detector s. Read Button: T his brings up a display of the detec tor output and flow rate which updates in r eal time. Relays: Brings up a screen allowing t he function of the volt-free ‘Fire’ and F ault LEDs to be tested

with the aid of a continuity meter or other t ester . The Fire relay contacts are open i n norm al oper ation and will close on test. The F ault relay contacts operate on a ‘Fail-safe’ basis and are held closed in normal operati on. They will therefore open on test.

Save As: Saves the summary list of scanned detectors and their status as a text (.txt) file. Print: Print s the summar y list to a connected printer.

9 Troubleshooting

9.1 Nuisance Alarms Occur Too Often

 Check that the Cl assiFi r e alarm factor setting is appropriate for the normal working environment of

the protect ed ar ea. See sect ion 2.2.4

 Check that the detec tor is not in Demonstration mode. Thi s can be ascertained by viewing the

event log (see section 2) and checking that the entr y Demo mode has a higher log entry number than the most recent F astLearn start and FastLearn end entr ies. Remember that the log entri es are in reverse order, with the most recent entries appearing first. If the log shows that Demonstration mode was invoked during the last F astLear n per iod, start a new FastLearn and allow it to complet e its 24-hour cycle (see section 2.2.6).

 From the event log (see section 6), check that 24 hours hav e elapsed sinc e the last FastLearn end

entry.

 Check that day- night switchover times are appropr iately set to reflect active and non-activ e peri ods

(see section 2. 3.1).

9.2 Elevated Smoke Levels Do Not Generate Alarm s

 Check that detect or is not Isolated or in FastLearn (if Isolated, the Fault light will be lit)  Check that the detec tor sampling points are in the smoke stream  Check that the corr ec t ClassiFire alarm setting has been set (see section 2.2.4)  Check that the detec tor has either had a 24 hour learning period or that it has been plac ed in

demonstration mode.

9.3 Low Mean Output

 Check that the filter does not require changi ng ( see section 2.8.3) and that the air plenum chamber

is clean. The chamber may become cl ogged when, for example, heavy building activity has occurred near the sampling pipes. If so, the chamber m ay require factory service. The det ec tor is not designed to handl e lar ge quantities of coarse debris and du st.

9.4 Detector Sensitivity Varies Over Time

 There are many reasons why particle densities m ay vary, and the ClassiFire system automatically

compensates f or this in order to replace the likeli hood of nuisance alarms due to normal variations in background sm ok e densi ty. Within limits set by the ClassiFir e alarm factor, this is a normal part of the detector‘s working.

9.5 Flow Fault Errors

 These occur when the airf low rate into the detect or is outside t he pre-programmed limits. As the

detector ‘l earns‘ the flow setup from the initi al installation, this usually means that there has been some change in conditions. A Flow high fault may indicate that a sampling pipe is damaged, and a Flow low fault may indi c ate that the pipe has been blocked, f or ex am ple, by near by building operations.

 If the detect or i nput is sampled from one area and the exhaust is in another area with different

pressure (for ex am ple the det ec tor is in a roof space and sampling from an enclosed room), this may lead to flow faults. In t his case it would be necessary to lead a pipe f r om the ex haust to the

9-5-0-344/ISS4/OCT10

Page 38 of 40 FIRElink-25 – Installation Manual

protected area to ensure normal flow. This will requir e the det ec tor to be installed using the piped exhaust docking station (see section 4. 1) .

9.5.1 "Low Flow" Error Messages.

 Check that the pi pe giv ing the error is not blocked  Check that the low flow fault threshold is not set too high (see section 2.7.3)

9.5.2 "High Flow" Error Messages

 Check that the pi pe is pushed home into the inlet and is not broken or crac k ed

 Check that installed pipe-work is fitted wi th an end-cap. The FIRElink PipeCA D ® pipe m odelling

software prom pts the use of appropriate end-caps.

 Check that the hi gh flow fault threshold is not set too l ow (see secti on 2.7.2)

Open bore pipes are not recommended.

10 Do's and Don'ts

 Ensure that the ClassiFire alarm factor i s appropriately set.  Ensure that cabl es are cor r ec tly connected before powering up by use of cable identifiers or

electric al c ontinuity checks. Incor r ect c onnec tion could damage the detector .

 Ensure that cabl e of an appropr iate approved type is used for interconnection.  Place sampling points so that the detector will be abl e to detect smoke at the earliest opportunity.  Ensure that the det ec tor exhaust is in an area with the same atmospheric pressure as the sampling

pipes, eit her by pl aci ng the det ec tor physically in the protect ed ar ea or by leading a pipe from the detector exhaust to the protected area.

 Ensure that the envir onm ent of the protected area is within the environmental operat ing parameters

of the detector (tem per ature -10 to +60°C, (humidity 0-90%, non-condensing).

DON’T

 Forget to set the appropr iate ClassiFire alarm factor for the area to be detected.  Forget to set the Det ector A ddr ess Switc hes corr ec tly when used in a net work.  Site detect or s i n damp or exposed areas.  Remove or connect boar ds when the detector is powered up.  Connect inter nal 0 v olt t erminals to local earth.  Attempt to re-use dust separat or c artridges once removed.  Attempt to adjust or alter detector settings other than via the user-programm able functions. In

particular , t he setting up of the laser is a precisi on task, and once set up the potentiometers should be left alone. If it is suspected that the laser alignment has shifted (e.g. after dr opping the detector), it should be returned to Hochiki Europe (UK) Ltd for r ecal ibration.

 Place the detector near high power RF sources.  Operate the detector with the front cover remov ed, or with one or more of the cover fixing screws

loose or missing.

 Test the response of t he detector using aerosol synthet ic smoke.
