FIRElink-25 – Installation Manual 2 Page 9 of 40 Programming the Detector The FIRElink-25 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 7.4, ‘Connecting to a PC’). 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 CD-ROM supplied with each detector.
Page 10 of 40 FIRElink-25 – Installation Manual 2.2 Alarm Levels and Delays Tab 2.2.1 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.
FIRElink-25 – Installation Manual 2.2.5 Page 11 of 40 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.
Page 12 of 40 FIRElink-25 – Installation Manual 2.3 Day/Night Switching Tab 2.3.1 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, e.g. 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.

Flow low limit and Flow high limit parameters are automatically set up on initial power-up. 2.7.
FIRElink-25 – Installation Manual 2.8.2 Page 15 of 40 Chart Recording Rate This function controls how frequently the detector and alarm level or flow rates are stored in the FIRElink25’s internal chart recorder log. (See section 2.10, ‘Chart Recording’).
Page 16 of 40 FIRElink-25 – 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 8, “Maintenance” for further details. 2.8.
FIRElink-25 – 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 2.2.6).
Page 18 of 40 FIRElink-25 – Installation Manual 2.10 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.
FIRElink-25 – 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.

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-25 detectors.
FIRElink-25 – Installation Manual Page 21 of 40 B Above Ceiling Sampling with detector mounted in ceiling void. 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’ branch-pipes is not recommended. To assist in design and to verify system performance, it is advisable to use the FIRElink PipeCAD® sampling pipe modelling software.
Page 22 of 40 FIRElink-25 – Installation Manual 3.2 EN54-20 Compliance The installation must be designed using PipeCAD software, which is provided free on the CD shipped with each detector. After designing the installation including pipes, endcaps and sampling holes, enter the detector type in the “Type” drop-down list in “Options” “Calculation options”. Select “Options” “Calculate” or click on the calculator icon.
FIRElink-25 – Installation Manual Page 23 of 40 compliant. If functions are changed, it is recommended that the system is retested if continuing compliance is in any doubt. *The results should be verified at installation by entering the installed detector's Fire 1 sensitivity (as indicated in the remote software histogram screen) into the PipeCAD “Options/Calculation options/Detector sensitivity” field and recalculating the layout results.
Page 24 of 40 4 FIRElink-25 – Installation Manual Installation Before installing the detector the local standards for installation of aspirating detection systems must be consulted as these standards differ throughout the world. Specific advice for one country may not be applicable to 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.
