dust separator for c ontamination, continually adjusting the
appropriate oper ating parameters to counteract the negative
effects of such contamination.
The FIRElink range of detectors is unique in being able to prov ide
a consistent lev el of protection in a very wide range of
environment s by continuously making minor adjustments to
sensitivity.
The FIRElink range of detectors has proven its worth many tim es
by detecting ‘dif ficult-to-detect‘ slow growth electrical overload
incipient fires in ‘difficult ‘ envi r onm ents.

1.1 Indicators
Fire indicator illuminates when
the alarm lev el has been
reached and the appropriate
time delays have expired.
Fault. Ill umi nates when the unit
has a fault and a fault signal is
being sent to the fire alarm
panel.
OK. Illuminates to show normal
operation when there are no
faults. Th e OK lamp will flash
during the 15 minute
Fastlearn™ peri od when the
detector is first learning about
its envir onm ent.
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.
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
Sensitivity
Probability of
Nuisance Alarm
Suggested Protected Area
4 Medium Once per 1000 years Warehouse
5 Medium Once per 5000 years Warehouse with diesel trucks operati ng
6 Medium Once per 10000 years Warehouse with diesel trucks operati ng
7 Low Once per 20000 years Warehouse with diesel trucks operati ng
8 Low Once per 100000 years Warehouse with diesel trucks operati ng
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.
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.
