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.
FIRElink-100 – Installation Manual 1.6.5 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-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.

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.
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 FIRElink100’s internal chart recorder log (see section 1.14, ‘Chart Recording’ on page 18).
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.
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).
Page 18 of 40 FIRElink-100 – Installation Manual 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.
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.
Page 20 of 40 2 FIRElink-100 – Installation Manual 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.
FIRElink-100 – Installation Manual Page 21 of 40 B Above Ceiling Sampling with detector mounted in ceiling void. 2.1 System Design Simple designs with short sampling pipes produce the best results. Complex sampling pipe runs should be avoided with the FIRElink-100 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-100 – Installation Manual 2.2 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-100 – Installation Manual Page 23 of 40 confirmed to be within the class limits shown above. The settings of a compliant system should be recorded, as it is possible by changing certain programmable functions to make the system noncompliant. If functions are changed, it is recommended that the system is retested if continuing compliance is in any doubt.
Page 24 of 40 3 FIRElink-100 – 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.
FIRElink-100 – Installation Manual 3.1.1 Page 25 of 40 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 mounting surface. Ensure that the sampling and/or exhaust pipes are securely seated in the pipe ports before fixing. If using a piped exhaust docking station be sure that the sampling and exhaust pipes are fitted into the relevant ports as shown in section 3.1. 3.1.

Page 28 of 40 4 FIRElink-100 – Installation Manual Interfacing Because of the flexible nature of the FIRElink-100 detector and the many possible configurations, there are many options for interfacing the detectors to the Fire Panel. These include many third party interfaces available from various manufacturers. Because of this, it is not possible to give a complete list of all interfacing methods but the following pages will give details of the most common methods that are likely to be used. 4.
FIRElink-100 – Installation Manual Page 29 of 40 4.2 Connecting a FIRElink-100 to a SenseNET/RS485 Detector Network Up to 127 detectors may be linked in a single SenseNET bus, supporting a total length of wire between adjacent detectors of up to 1.2km. In the above example, two FIRElink-100 detectors are linked into a 127-detector bus with a Command Module and a number of FIRElink-400 detectors.
Page 30 of 40 FIRElink-100 – Installation Manual 4.3 Connecting a FIRElink-100 to an addressable Fire Panel An Addressable Programmable Interface Card (FIRElink-APIC) may be used to decode detector information and to relay this to a Fire Panel.
FIRElink-100 – Installation Manual Page 31 of 40 NOTE: The detector address on the SenseNET loop and the Fire Panel addressable protocol address are the same, in other words, no address translation is performed. Some protocols may not support all the available alarm levels and fault reporting is usually a general fault with no detailed fault information. Please consult the specific FIRElink-APIC protocol documentation for more information. 4.

Page 34 of 40 6 FIRElink-100 – Installation Manual Commissioning Before commissioning the detector the local standards of aspirating detection systems must be consulted. These standards differ widely throughout the world and specific advice for the market in one country may not be applicable to another. Commissioning strategy will initially depend upon the environment in which the detector is installed.
FIRElink-100 – Installation Manual 7 Page 35 of 40 Maintenance FIRElink-100 is a very low maintenance detection system. If required, external cleaning of the unit should be performed using a damp (not wet) cloth. Do not use solvents as these may mar the front panel label. The only part that may require field replacement during servicing is the dust separator assembly*.
Page 36 of 40 FIRElink-100 – Installation Manual Click on the list entry to highlight it and click on the Diagnostics button. The software will then commence the system tests. During the “Aspirator and flow” test, the detector fan will suddenly slow down, but this is a normal part of the test.
FIRElink-100 – Installation Manual 8 Page 37 of 40 Troubleshooting 8.1 Nuisance Alarms Occur Too Often Check that the ClassiFire alarm factor setting is appropriate for the normal working environment of the protected area. See section 1.6.4 Check that the detector is not in Demonstration mode. This can be ascertained by viewing the event log (see section 1.4) and checking that the entry Demo mode has a higher log entry number than the most recent FastLearn start and FastLearn end entries.
