1.4 Programming the Detector

The FIRElink - 100 m ay 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 “ Connec ting 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 sof tware in accordance with the on-screen i nstr uc tions. To open the software , select St art > Programs > Hochiki > Remote 3.0

Access the drop-down list to the right hand side of the toolbar. This defaults to “Detect or 001”. Scr oll down this list t o select the det ec tor number corresponding to the connected detector’s address number if the address is other t hen the factory default setti ng of 1 (see section “Setting the Det ec tor Address” on page 28).

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-100. To amend one of t he programmable functions, go to the relevant tab, make the change and then click OK. This will save the change to the detec tor’s internal firmware.

A list and explanation of the various functions is given below, with the functi ons 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 cal endar /clock because it uses this inf ormation to store events in the event log. See section 5 “Event Log” on page 32 for more details. Unless speci ally ordered, units are supplied with the correct setting for UK time. This is

9-5-0-345/ISS4/OCT10

Page 10 of 40 FIRElink-100 – Installation Manual

backed up with a rechargeable battery. Later adjustm ents to the clock setti ng shoul d 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 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 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 Fi r e alarm. The def ault level settings for Pre-Alarm and Fire 1 are 6 and 8 respectively. The def aul t sett ing for Fire 2 is 20% obs/m.

1.6.2 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.

1.6.3 ClassiFire® Override

This functi on has no curr ent use on the FIRElink-100 but is reserved for future expansion purposes.

1.6.4 Alarm Factor

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

Note: The highest sensitivity setting is suit able for clean, environm entally controlled envir onm ents, for

example semic onduc tor manufacturing clean r oom s where airborne pollut ants are kept to an absolute minim um and the least contamination is cause for alarm.

Use of this setti ng in a busy mac hine shop would lead to relatively frequent nuisance alarm s due

to the normal vari ation of atmospheric contamination and a lower sensitivity setting is recommended. I t is theref ore important that the alarm fact or chosen is suitable for the area to be protected. When the appropriate alarm factor for the protected ar ea 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 room 1 Once per 5 years Computer room

Sensitivity

Probability of Nuisance Alarm

Suggested Protected Area

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 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

FIRElink-100 – Installation Manual Page 11 of 40

1.6.5 LDD Enable

When this function is ticked, Laser Dust Discrimination (LDD™) increases the respon se time of the detector slightly, whilst greatly r educi ng the likelihood of nuisance 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 rooms, due to the

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

1.6.6 FastLearn Enable

If the detect or i s 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 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 pr ocess, and will then change 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 secti on 1.6. 9 “ Dem o M ode” on page 11) . It is essential for proper functioning that the detector not be left in Demonstrat ion 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 det ec tor 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 aut om atically 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.

1.6.8 ClassiFire 3D

If this function is ticked, then the detect or will ignor e any pr e- set time delays in the event of an unacceptably r apid increase in smoke densit y, thereby mi nimi sing 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.

1.6.9 Demo Mode

Demonstration mode is an operating mode whereby the normal 24-hour learni ng 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.

1.7 Day/Night Switching Tab

1.7.1 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, f or example 19 for 7pm. Day and night switching is intended so that t he detec tor may automatically sel ect a diff er ent sensitivity when the protected area is unoccupied and fewer cont am inants are being produc ed. ClassiFire automatically detects the change in smoke level after the protected area is left, and if the time at which this happens is withi n + 70 mi nutes of the programmed switchover time it selects the night-time histogram. This means that changes in time setting, for example changing to summer tim e, 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 envir onm ent actually becomes more contami nated during the night period f or any

reason then ClassiF ire 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 perm anently in day mode.

1.8 Alarm Actions Tab

1.8.1 Remote Functions (Remote Input subgroup)

These functi ons have no current use on the FIRElink-100 but are r eserved for future expansion purpose s.

1.8.2 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, for use during detec tor m aintenance for example. The “Fault” light will be illuminated on the detector front panel. The isolated condition will be disabled automatic ally aft er 7 days if not manually disabl ed. This function is disabl ed by default.

1.8.3 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 untic k ed, 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 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.

1.8.5 Cascading Alarms

Ticking this function box means that only when the detector ’s cont r oller has gone into Pr e-Alarm does the controller star t counting down the main Fire delay , in other words t he time delays on Pre-Alarm and Fire 1 are cumulative. The Aux alarm is not included in the cumulativ e delay since it may be set to a higher level than eit her the Pr e- Al arm or Fir e 1 lev els. This function is enabled by def ault.
