1 Introduction

FIRElink-400 is a highly sophisticated ‘next generation‘ of High Sensitivity Aspirating Smoke Detection products that has been designed to ensure that installation and commissioning is as simple as possible, while optimising performance.

FIRElink-400 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.

FIRElink-400 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. FIRElink-400 has proven its worth many times by detecting ‘difficult-to-detect‘ slow growth electrical overload incipient fires in ‘difficult‘ environments.

2 Types of Detectors

2.1 FIRElink-400 Standard Detector

The Standard Detector may be operated as a stand-alone unit, or may be part of a network of detectors centrally monitored by a Command Module (see "FIRElink400CM Command Module Detector & FIRElink-CM Stand Alone Command Module on page 7).

It may be programmed via the front panel as in the version shown left. Alternatively, and for detectors ordered without front panel display, the detector may be programmed remotely via the detector’s RS485 terminals using a Command Module, or via the detector’s RS232 port using a PC running the remote control software. A copy of this software is packed with each detector supplied.

FIRElink-400 Air Sampling System – Installation Manual Page 7 of 58

2.2 FIRElink-400CM Command Module Detector & FIRElink-CM Stand Alone Command Module

When multiple detectors are networked together, a Command Module may be used to tie all the detectors together and to provide a central point for programming, running diagnostics and PC and fire panel connection.

The Command Module can be mounted either inside a detector as shown or as a stand-alone unit in its own housing without an aspirator or smoke detection circuitry.

If detectors attached to the Command Module are mounted in different fire zones then the Command Module must be mounted in its own housing with separate power supply to comply with BS5839 and EN54.

When a Command Module is mounted inside a detector, the Standard Detector display is replaced with a dedicated Command Module display. The programming buttons and display on the front of the detector belong to the Command Module.

Programming from the Command Module is very similar to programming a detector, the main difference being that the Command Module has extra functions to control all the FIRElink-400 detectors connected to the detector loop.

Smoke density indicators. This display is in two sections. The first part, labelled 1 to

10, is the relatively scaled ClassiFire ® bar graph and changes in steps of half a segment. The second part displays absolutely scaled smoke levels above 1% obscuration per metre (% obs/m) to a maximum of 25% obs/m. The Fire 2 activation level is programmed normally somewhere in this range. The bar graph display will show a continually cycling pattern when the unit is in FastLearn mode.

On the Command Module display, this will occur when any unit on the RS485 communications loop is in FastLearn. Otherwise, the bar graph display on the Command Module will mimic the bar graph display on the highest-reading detector on the loop.

Status display (if fitted). This display shows all events as they happen in real time and

is also used to configure the unit. See section 4 “Programming the unit” on page 14 for more information.

RESET. When enabled, pressing <RESET> will clear any latched alarms or faults and

set the status display back to its normal operation display. To comply with national standards, detectors are supplied with the RESET function disabled as default.

TEST. When enabled, pressing <TEST> will start a lamp test and then the detector will

show its nominal operating sensitivity as calculated by the ClassiFire Artificial

NOTE: These three buttons can be individually enabled or disabled. The factory default state of the

detector is for only the <TEST> button to be enabled and for <RESET> and <ISOL> to be disabled

Intelligence System.

ISOL. Pressing <ISOL> will toggle the unit‘s isolation state. When isolated, the unit

cannot generate any alarms and will signal a fault condition and the text display will show Panel Isolate. To comply with national standards, detectors are supplied with the ISOL button disabled as default.

These buttons, also referred to in the text as menu buttons or by name, for example <ENTER>, are used when programming the unit, which is pass code protected. See section 4 “Programming the unit” on page 14 for more information. Pressing when not in programming mode (the access code has NOT been entered) will scroll through the detector’s event log. See section 8 “Event Log” on page 44 for more information.

FAULT. Illuminates when the unit has a fault and a fault signal is being sent to the fire

alarm panel. On the Command Module, this also indicates a fault in a detector on the communications loop, or in the loop itself.

OK. Illuminates to show normal operation when there are no faults. On the Command

Module this means that the Command Module and all detectors on the loop are

operating normally.

4.1 Engineering Access Code

The Engineering Access code is required to allow the detector parameters to be programmed. The access code is only valid whilst the user is in programming mode. It will need to be entered again if programming mode is exited, if the detector is powered down or if <RESET> is pressed.

To enter programming mode, press a menu key

Acces s code:0000 asking for the engineering access code. The factory default access code is

0102. To enter the default access code, follow the sequence shown:

NOTE: Pressing or has no effect until is pressed to place the cursor under the first digit.

, ,or . The unit responds by displaying the prompt

This correctly sets the access code. If an incorrect access code is entered or <RESET> is pressed, the display will show access code.

All of the programmable functions work in a similar manner. The through the user-settable digits and the selected digit (for example 1 - 99, Yes / No etc). Pressing

NOTE: That it is not possible to save an illegal value, for example for the Fire 1 level the maximum valid

input is 10 and it would be possible to enter 99, but the programmer will display Bad value to

inform you that the entry is invalid and prompt for the value to be re-entered. All programmable parameters have the valid input values range in brackets below the parameter legend on the display.

Having edited the value as required, press to select the amended setting. Pressing when the cursor is on the right most digit has the same effect. If no programming activity is detected for 5 minutes, the detector will display the legend

4.4 FIRElink-400 Functions

A list of all programmable functions follows with an explanation of their usage and the menu and submenu in which they can be found. The location of each sub-menu and function within the main menu is shown in the menu map (section 4.5 on page 27). The menu map also shows the valid input range for programming parameters.

Each function listed below gives the following information:

 Function name and description

 Type of function. There are five types of function: Yes/No, Numeric, Alpha (alphanumeric), Display

and Test. In the case of the Display and Test functions, the user cannot amend the parameters

shown.

 The menu and submenu within which the function can be found.

 Applicability. The legend "CM only" means that the function applies only to the Command Module

and is not present in the Standard Detector’s list.

The legend "Address 000-127" means that the function may apply to the Command Module and the Standard Detector (allowable addresses from 000 to 127).

test

are examples of these.

All other functions are present in both the Standard Detector and Command Module function lists and are used to program the detectors. They can either be remotely set on the Command Module, or locally on the detector front panel. These are annotated "Address 001-127" since they do not apply to the Command Module itself.

Where a programmable function on the Command Module applies to a Standard Detector, the Command module will scan the loop and, if more than one detector is present, will prompt the user for the address of the detector to be programmed. If the function applies to the Command Module, the address "000" should be entered. For other detectors on the loop (including the detector element of a Command Module detector), the value is the same as the address set on the detector’s internal DIP switch. If a user enters an address which does not appear on the loop, the error message

This message will also appear if the Command Module address "000" is entered into a function which only applies to detectors, in other words anything except "CM only" and "Address 000-127" functions.

Time and date and Relay

Bad detector will appear.

1.1.1 Time and Date (Numeric – Address 000-127)

Setup Menu > Time and date

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 8 “Event Log” on page 44 for more information. Unless specially ordered, units are supplied with the correct setting for UK time. This is backed up with a rechargeable battery. Later adjustments to the clock setting should not exceed ± 70 minutes unless a FastLearn is initiated.

1.1.1 Alarm Levels (Numeric – Address 001-127)

Setup Menu > Alarm levels

The value set in the Pre Alarm level , Fire 1 level and Aux level functions in the Alarm levels submenu is the relatively scaled bargraph level at which the appropriate alarm is initiated on the detector. The Fire 2 level function assigns an absolutely scaled alarm level in % obs/m to the Fire 2 alarm. The Aux level is set by factory default at level 10 which means that this alarm will occur after the Fire 1 alarm.

1.1.1 Alarm Delays (Numeric - Address 001-127)

Setup Menu > Alarm levels

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.

1.1.1 ClassiFire® Override (Numeric - Address 001-127)

Setup Menu > Alarm levels

When this function is set to a value other than zero, the shorting together of one of the "Input 3" contacts on the detector main circuit board by means of volt free contacts will desensitise the detector by moving the alarm levels out by the specified percentage.

1.1.1 ClassiFire® Alarm Factor (Numeric - Address 001-127)

Setup Menu > Alarm levels

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.

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

0 Extremely High Once per year Semiconductor manufacturing clean room

1 Once per 5 years Computer Room

1.1.1 Hour Start of Day and Night Operation (Numeric - Address 001-127)

Setup Menu > Alarm levels

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, 19:00 for 7pm. If no day/night switching is required, then both entries should be set to 00:00. 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.

NOTE: 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. The system will automatically compensate for 1 hour seasonal time-changes.

1.1.1 LDD™ Enable (Yes/No - Address 001-127)

Setup Menu > Alarm levels

When this function is set to Yes, 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 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.

No.

1.1.1 Start / Stop FastLearn (Yes/No - Address 001-127)

Setup Menu > Alarm levels

If the detector is in FastLearn mode, setting this function to No will stop the FastLearn process. Using the function in this way is neither recommended nor supported by Hochiki Europe (UK) Limited. Setting this function to show a rolling segment display on the front panel for the fifteen minutes that it takes to complete.

The text display will initially display the legend until the FastLearn is complete.

IMPORTANT

Yes will start a FastLearn at any time. The bar graph display on the front of the detector will

FastLearn 15 and will then count down each minute

It will take a further 24 hours after the FastLearn for full sensitivity to be reached, unless Demonstration Mode has been initiated. It is essential for proper functioning that the detector not be left in Demonstration mode, and that it be allowed to complete the 24hour learning period. To cancel demo mode, set this function to Yes or power down and restart the detector to initiate FastLearn mode.

NOTE

1.1.1 Auto FastLearn Enable / Disable (Yes/No - Address 001-127)

Setup Menu > Alarm levels

As default, this function is set to Yes. This ensures that if the detector is powered down for any reason (for example, for maintenance or to be moved to a new area), 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
