Aspirating smoke detectors

for fire detection and fire alarm

systems for buildings

CLASS A, B and C

Technical data: see INF48027 held

by the manufacturer

FIRElink-100 incorporates a patented ‘artificial intelligence‘

known as ClassiFire ®, which allows the detector to configure

itself to optimum sensitivity, alarm thresholds and minimum

nuisance alarms for any environment. ClassiFire intelligence

also monitors the detector chamber and dust separator for

contamination, continually adjusting the appropriate operating

parameters to counteract the negative effects of such

contamination.

The FIRElink range of detectors is unique in being able to

provide a consistent level of protection in a very wide range

of environments by continuously making minor adjustments

to sensitivity. The FIRElink range of detectors has proven its

worth many times by detecting ‘difficult-to-detect‘ slow growth

electrical overload incipient fires in ‘difficult‘ environments.

This handbook gives information likely to be needed for most

installations, but for more detailed information on subjects

such as Fresh Air Referencing, please refer to the complete

Technical Manual or System Design Guide.

This equipment is Class 111 as defined in EN60950 (i.e., this

equipment is designed to operate from Safety Extra Low

Voltages and does not generate any hazardous voltages).

NOTE: If this equipment is part of a fire detection system, it should be supplied from an approved power

supply conforming to EN54-4.

This symbol appears on the main board of the unit and indicates that the board

contains static sensitive components. Suitable anti-static precautions must be

taken when handling the board.

LASER CLASS 1

PRODUCT

This label is located on the laser chamber and signifies that the unit is a Class 1

Laser product as specified in IEC 60825-1. The unit incorporates a Class 3B

embedded laser that must not be removed from the detector as retinal damage

may result if the laser beam enters the eye.

This symbol appears on the main board of the unit and indicates that the board

contains static sensitive components. Suitable anti-static precautions must be

taken when handling the board.

FIRElink-100 – Installation Manual Page 9 of 40

1.4 Programming the Detector

The FIRElink-100 may be programmed from a PC when connected to the detector via 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 4.4 “Connecting to a PC” page 31). In order to do this, it is necessary to install the remote

control software onto the computer. A copy of the remote control software is contained on a floppy disk

supplied with each detector. Install the software in accordance with the on-screen instructions. To open

the software, select Start > Programs > Hochiki > Remote 3.0

Access the drop-down list to the right hand side of the toolbar. This defaults to “Detector 001”. Scroll

down this list to select the detector number corresponding to the connected detector’s address number if

the address is other then the factory default setting of 1 (see section “Setting the Detector Address” on

page 28).

The programmable functions are all accessed though the Options > Detector settings submenu or by

clicking on the detector button on remote software toolbar as indicated below:

The following screen is displayed:

This window contains all the programmable functions for the FIRElink-100. To amend one of the

programmable functions, go to the relevant tab, make the change and then click OK. This will save the

change to the detector’s internal firmware.

A list and explanation of the various functions is given below, with the functions grouped by the tab under

which they appear.

1.5 Time and Date Tab

It is important that the time and date be set up correctly on the controller’s internal calendar/clock

because it uses this information to store events in the event log. See section 5 “Event Log” on page 32

for more details. Unless specially ordered, units are supplied with the correct setting for UK time. This is

Page 10 of 40 FIRElink-100 – Installation Manual

backed up with a rechargeable battery. Later adjustments to the clock setting should not exceed ± 70

minutes unless a FastLearn is initiated.

1.6 Alarm Levels and Delays Tab

1.6.1 Alarm Levels - (Level subgroup)

The value set in the Fire, Pre-Alarm and Aux functions in the Level subgroup is the relatively scaled

bargraph level at which the appropriate alarm is initiated on the detector. 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 Fire

alarm. The default level settings for Pre-Alarm and Fire 1 are 6 and 8 respectively. The default setting for

Fire 2 is 20% obs/m.

1.6.2 Alarm Delays - (Delay subgroup)

The alarm delay is the number of seconds that an alarm level has to be continuously sensed before the

alarm is initiated. Each alarm level has a programmable delay of between 0 and 90 seconds. The default

delay for each alarm level is 5 seconds.

1.6.3 ClassiFire® Override

This function has no current use on the FIRElink-100 but is reserved for future expansion purposes.

1.6.4 Alarm Factor

The detector sensitivity is set with this entry, which will also affect the probability of nuisance alarms. 0 =

high sensitivity, higher probability, 8 = low sensitivity, lower probability. The default alarm factor is 4.

Note: The highest sensitivity setting is suitable for clean, environmentally controlled environments, for

example semiconductor manufacturing clean rooms where airborne pollutants are kept to an

absolute minimum and the least contamination is cause for alarm.

Use of this setting in a busy machine shop would lead to relatively frequent nuisance alarms due

to the normal variation of atmospheric contamination and a lower sensitivity setting is

recommended. It is therefore important that the alarm factor chosen is suitable for the area

to be protected. When the appropriate alarm factor for the protected area has been set, nuisance

alarms will be reduced to an absolute minimum.

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

Alarm

Factor Sensitivity Probability of

Nuisance Alarm Suggested Protected Area

0 Extremely High Once per year Semiconductor manufacturing clean room

1 Once per 5 years Computer room

2 Once per 10 years Non-smoking office

3 Once per 50 years Clean factory

4 Medium Once per 1000 years Warehouse

5 Medium Once per 5000 years Warehouse with diesel trucks operating

6 Medium Once per 10000 years Warehouse with diesel trucks operating

7 Low Once per 20000 years Warehouse with diesel trucks operating

8 Low Once per 100000 years Warehouse with diesel trucks operating

FIRElink-100 – Installation Manual Page 11 of 40

1.6.5 LDD Enable

When this function is ticked, Laser Dust Discrimination (LDD™) increases the response time of the

detector slightly, whilst greatly reducing the likelihood of nuisance alarms due to dust ingress. LDD may

be disabled in very clean rooms for a slightly faster response to smoke by setting this function to unticking

the box. This function is enabled by default.

NOTE: Disabling LDD is not recommended for areas other than manufacturing clean rooms, due to the

increased probability of nuisance alarms in most other operating environments.

1.6.6 FastLearn Enable

If the detector is in FastLearn mode, unticking this box will stop the FastLearn process. Using the

function in this way is neither recommended nor supported by Hochiki Europe (UK) Limited).

Ticking the box will start a FastLearn at any time. The green “OK” LED on the front of the detector will

flash for the fifteen minutes that it takes for the FastLearn process, and will then change to constant

illumination to indicate that the FastLearn is complete.

Note: It will take a further 24 hours after the FastLearn for full sensitivity to be reached, unless

Demonstration Mode has been initiated (see section 1.6.9 “Demo Mode” on page 11). It is

essential for proper functioning that the detector not be left in Demonstration mode, and that it be

allowed to complete the 24-hour learning period. To cancel demo mode, tick this box or power

down and restart the detector to initiate FastLearn mode.

1.6.7 Auto FastLearn Enable

When enabled, this function ensures that if the detector is powered off for any reason (for maintenance or

to be moved to a new area for example), a FastLearn is commenced automatically on power-up.

There may be occasions when it is desirable to power down the detector for short periods of time, and it

is highly likely that ambient contaminant levels will be the same on power-up. Under these circumstances

it may not be desirable that the detector should to go through the whole learning process again. To this

end, this function can be unticked before power-down, whereupon it will return to the original settings on

power-up. This function is enabled by default.

1.6.8 ClassiFire 3D

If this function is ticked, then the detector will ignore any pre-set time delays in the event of an

unacceptably rapid increase in smoke density, thereby minimising response time to 'rapid growth' fires.

This function would normally only be used where there were long time delays programmed on the alarm

levels. This function is disabled by default.

1.6.9 Demo Mode

Demonstration mode is an operating mode whereby the normal 24-hour learning period is bypassed, so

that the detector can reach high sensitivity after 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.

Page 12 of 40 FIRElink-100 – Installation Manual

1.7 Day/Night Switching Tab

1.7.1 Day Start / Night Start –

These values are the 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, for example 19 for 7pm. Day and night switching is

intended so that the detector may automatically select a different sensitivity when the protected area is

unoccupied and fewer contaminants are being produced. ClassiFire automatically detects the change in

smoke level after the protected area is left, and if the time at which this happens is within + 70 minutes of

the programmed switchover time it selects the night-time histogram. This means that changes in time

setting, for example changing to summer time, may be ignored as the detector will take this into account.

The default times for day and night start are 08:00 and 19:00 respectively.

NOTE: That if the environment actually becomes more contaminated during the night period for any

reason then ClassiFire will adapt to that too, reducing the night-time sensitivity.

1.7.2 Disable Day / Night Switching

If day/night switching is not desirable, the Disable day/night switching box may be ticked to leave the

detector permanently in day mode.

1.8 Alarm Actions Tab

1.8.1 Remote Functions (Remote Input subgroup)

These functions have no current use on the FIRElink-100 but are reserved for future expansion purposes.

1.8.2 Programmed Isolate

When this function is ticked the controller will not generate alarms and will not indicate a fault condition on

any fire panel which is connected, for use during detector maintenance for example. The “Fault” light will

be illuminated on the detector front panel. The isolated condition will be disabled automatically after 7

days if not manually disabled. This function is disabled by default.

1.8.3 Latching Alarms

When this function box is ticked it requires a reset from the controlling computer to clear an alarm

condition. If unticked, the alarm signal is extinguished as soon as the alarm condition ends. This is the

factory default setting.

1.8.4 Latching Faults

When this function box is ticked it requires a reset from the controlling computer to clear a fault condition.

If unticked, the fault signal is extinguished as soon as the fault condition ends. This is the factory default

setting.

1.8.5 Cascading Alarms

Ticking this function box means that only when the detector’s controller has gone into Pre-Alarm does the

controller start counting down the main Fire delay, in other words the time delays on Pre-Alarm and Fire 1

are cumulative. The Aux alarm is not included in the cumulative delay since it may be set to a higher

level than either the Pre-Alarm or Fire 1 levels. This function is enabled by default.

FIRElink-100 – Installation Manual Page 13 of 40

1.9 Device Information Tab

1.9.1 Device Type

This function is for display purposes only. It shows any special designation for the unit, which will

normally be FIRElink-100.

1.9.2 Firmware Version

This function is for display purposes only. It shows the version number of the fitted firmware chip.

1.9.3 Run-time Hours

This function is for display purposes only. It shows the cumulative total number of hours that the device

has run (this is not the time that has elapsed since last power-up, but the sum total of run time since the

detector memory was last reset).

1.9.4 Watchdog Count

The watchdog is a circuit built into the controller that restarts the controller in the event of a failure to

function properly. This could be as a result of electrical spikes. This count shows the number of

interruptions found. The details of each problem can be found in the event log. See section 5, “Event

Log” on page 32for further details.

1.9.5 Device Text

This function has no current use on the FIRElink-100 but is reserved for future expansion purposes.

1.10 Referencing Tab

1.10.1 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 reference detector, enter its address

as set by its internal DIP switch into this function. This function is disabled by default.

1.10.2 Reference Enable

Ticking this box enables the reference for the detector, if one has previously been allocated in Reference

detector (see section 1.10.1). This function is disabled by default.

1.10.3 Reference Level

The value set with this function is the percentage reference signal subtracted from the detector’s signal, if

a reference device has been allocated. The default value is 0.

1.10.4 Reference Back-off

This value is the delay time between a build up of pollution being seen by the reference (if used) and the

pollution being seen by the detector. The default value is 15.

Page 14 of 40 FIRElink-100 – Installation Manual

1.11 Flow Monitoring Tab

1.11.1 Flow Rate

This function is for display purposes only, and shows a value corresponding to the current airflow through

the detector.

1.11.2 Flow High Limit

This value is the level above which airflow needs to increase to trigger a fault indication (which may

indicate a loose or damaged inlet pipe). Flow low limit and Flow high limit parameters are automatically

set up on initial power-up.

1.11.3 Flow Low Limit

This value is the level below which airflow needs to be reduced to trigger a fault reading (which may

indicate a blocked pipe). Flow low limit and Flow high limit parameters are automatically set up on initial

power-up.

1.11.4 Flow Fault Delay

This feature requires the Remote Control Software version 3.2 or later, available from the Hochiki Europe

Technical Support Department (psupport@hochikieurope.com).

The default flow fault thresholds on the FIRElink-100 are set to meet the stringent airflow monitoring

requirements of EN54-20, with a default flow fault delay of 30 seconds. This may lead to unwanted flow

faults being generated when local conditions cause short-term variations in airflow. To help alleviate such

issues, the flow fault delay is programmable from 30 to 240 seconds. The flow level needs to be above

the high flow threshold or below the low flow threshold throughout the delay period for a fault to be

generated.

NOTE: When setting the value of this function, it is important to take into account that the control unit (for

example, fire panel) may not react immediately to a trouble signal being generated by the

detector, and this will add to the total fault response time of the system.

The function value must be chosen so that the total time between the detector entering a fault condition

and a fault signal being generated by the panel meets the requirements of local or national fire

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 limit), but the

fire panel did not generate a fault indication for another 25 seconds, the total response time of 205

seconds means the system would not comply with the regulations.

If documented figures are unavailable for the fire panel reaction time, compliance with reaction time

regulations may only be verified by post-installation testing.

1.12 Miscellaneous Tab

1.12.1 Access Code

This is the access code required to amend programmable parameters. 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.

FIRElink-100 – Installation Manual Page 15 of 40

1.12.2 Chart Recording Rate

This function controls how frequently the detector and alarm level or flow rates are stored in the FIRElink-

100’s internal chart recorder log (see section 1.14, ‘Chart Recording’ on page 18).

Setting Type Storage Interval Time per Division on Chart Log

0 Detector Output 1 second 10 seconds

1 Detector Output 5 seconds 50 seconds

2 Detector Output 12 seconds 2 minutes

3 Detector Output 30 seconds 5 minutes

4 Detector Output 1 minute 10 minutes

5 Detector Output 2 minutes 20 minutes

6 Detector Output 5 minutes 50 minutes

7 Detector Output 10 minutes 100 minutes

8 Detector Output 20 minutes 200 minutes

9 Detector Output 50 minutes 500 minutes

10 Flow Recording 1 second 10 seconds

11 Flow Recording 5 seconds 50 seconds

12 Flow Recording 12 seconds 2 minutes

13 Flow Recording 30 seconds 5 minutes

14 Flow Recording 1 minute 10 minutes

15 Flow Recording 2 minutes 20 minutes

16 Flow Recording 5 minutes 50 minutes

17 Flow Recording 10 minutes 100 minutes

18 Flow Recording 20 minutes 200 minutes

19 Flow Recording 50 minutes 500 minutes

In the above table the shaded cells indicate flow rate recording whilst the white cells indicate detector and

alarm level recording.

At the slowest recording rate, one month of data can be recorded. The factory default setting is 8.

1.12.3 Separator Condition

The value given at this function is the efficiency rating of the dust separator element in the detector as a

percentage of the efficiency of a clean separator. A new element will give a reading of 99 in this function.

When the efficiency has decreased to 80%, the Fault indicator LED will illuminate and the event log will

show “Separator renew”.

NOTE: Fitting a new element will reset this figure to 99

1.12.4 Separator Change Date

This function defaults to “--“, which means that a separator fault will only appear when the efficiency

decreases to 80% (see 1.12.3, “Separator Condition”). However, a date may be entered into this function

Page 16 of 40 FIRElink-100 – Installation Manual

to allow for a scheduled maintenance period. The detector will then generate a separator fault at the

planned time regardless of the condition of the separator, although degradation of the separator to below

80% efficiency before this date will override this (see section 7, “Maintenance” on page 35 for further

details.

1.12.5 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 Fastlearn is enabled (see section 1.6.7 “Auto FastLearn Enable” on page 11). 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 ClassiFire alarm factor other than the default is required

for the protected area, this will need to be re-entered. Section 1.6.4 gives details of the ClassiFire alarm

factors.

1.13 Other Remote Software Features

1.13.1 Reset

If latching alarms (see section 1.8.3) or latching faults (see section 1.8.4) are enabled, the relevant alarm

or fault warnings will remain on the detector front panel LEDs and controlling unit until a reset is

performed. If using SenseNET software, individual detectors can be reset (refer to the SenseNET User

Guide for details). In the remote software, a global reset is available which resets all detectors on the

SenseNET loop, or a single stand-alone detector.

To perform a reset, either select the menu options Options > Global Reset or click the button on the

toolbar as indicated below:

1.13.2 Histogram Screen

The histogram screen shows various aspects of the detector function. To enter the histogram screen,

either select the menu options View > Histogram Viewer, or click the button on the toolbar as indicated

below:

The following screen is displayed:

FIRElink-100 – Installation Manual Page 17 of 40

Smoke Density histogram Alarm flags

There are two types of smoke density histogram; one shown in blue (the “fast” histogram) which updates

every 15 minutes, feeding information to the long-term “slow” histograms (which appear in yellow). These

set the detector sensitivity based on the ambient smoke conditions and it takes 24 hours for the two slow

histograms (the “day” and the “night” histograms) to complete their learning phase (see section 1.6.6).

Detector sensitivity is based on the fast histogram during FastLearn and is thereafter based on the

currently active slow histogram. However, although the positions of the alarm flags are based on the slow

histogram, sudden changes in smoke density are picked up by the fast histogram so that early warning is

given.

Sensitivity: The current absolute sensitivity of the detector in percentage obscuration per metre (%

obs/m)

Mean: The current mean value of smoke density, taken from the currently “active” histogram 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

deflection.

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

remaining in the FastLearn period. When this period has elapsed it will read “OFF”.

Alarm factor: This is the ClassiFire alarm factor (see section 1.6.4 “Alarm Factor” on page 10)

Day/night: This indicates the currently active slow histogram

Alarm levels: These figures give the position of the various alarm flags in terms of a percentage of full

scale deflection.

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

percentage of full scale deflection.

1.14 Chart Recording

The chart recording function shows how smoke density in the protected area has varied over time. The

chart may be downloaded to disk or printed out from a connected printer.

To access the chart log, select the menu options View > Chart Recording or click the button on the

toolbar as indicated below:

The following screen is displayed:

The red trace is the current alarm level and the black trace is the detector output. By moving the cursor

along the chart, the “Chart information” window (shown at the bottom left) updates to show the date and

time, detector level and alarm level of the relevant period. The File menu option in the chart recording

window allows the chart recording to be saved to disk or printed to a connected printer, and allows a

previously saved chart recording to be loaded. Chart recording files have the extension “.rcw”.

1.15 Load / Save Function Settings

Where a custom set of programmable function settings is commonly used, these may conveniently be

saved to or loaded from disk. To open a detector function settings (.dfs) file, select the menu options File

> Open or click on the button on the toolbar as indicated below:

A file browser window will be displayed, click on the “List files of type” drop-down box and select “Detector

settings (*.dfs)” as indicated below:

FIRElink-100 – Installation Manual Page 19 of 40

A list will appear of all detector settings files stored on the current drive. As a special case, if desiring to

recall the factory default settings, there is a file named ‘default.dfs’ in the ‘remote2k’ directory. Loading

this file will reset the detector to the factory default.

2 Design Limitations

FIRElink-100 is intended to provide LOCALISED incipient fire detection only. This

means that it is suitable for the substantial range of applications typified by; small

non-compartmentalised rooms, warehouse racking, or pieces of electronic or

electromechanical equipment where it is desirable to achieve individual incipient fire

reporting. In compartmentalised rooms, each compartment would normally use

individual FIRElink-100 detectors.

This product employs a very low-power aspirator and the aspirating capability of the FIRElink-100

detector is limited accordingly. FIRElink-100 is NOT intended to protect large areas, or to sample from

areas where there may be any difference in airflow rates or pressure differentials. Application of

FIRElink-100 in these circumstances is not recommended. If detection in environments conforming to

these descriptions is required, alternative versions of FIRElink products should be used.

Maximum length of sampling pipe used with the FIRElink-100 detector is 100 metres in STILL AIR with 20

sampling holes (or Capillary Remote Sampling Points). This will provide a transport time from the end of

the sampling pipe within 120 seconds. If the protected area has airflow present, the maximum permitted

sampling pipe length will be reduced. In areas or applications where the airflow rate exceeds 1 metre per

second, maximum sampling pipe length is reduced to 50 metres.

Sampling pipes must have capped ends. The end cap should be drilled with a hole normally between 4

or 5mm diameter and free from burrs. Sampling holes should normally be 3-4mm diameter or as

calculated by PipeCAD, and free 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

requirements. It is strongly recommended that the smoke transit time from the furthest sampling hole be

checked during commissioning tests. Capillary Remote Sampling Points may be used in place of

sampling holes.

FIRElink-100 is supplied with a ‘Piped Exhaust’ type Docking Station (see illustration A). This is primarily

intended to allow the FIRElink-100 detector to sample from areas that may be at a different air pressure

to the detector location. Typical uses are for air-duct sampling and allowing the installation of the detector

in under-floor or ceiling voids or when sampling from pieces of computer related equipment.
