Installation &
Commissioning

13. Commissioning
Equipment Required
• Appropriate installers
handbook (Supplied on CD)
• A laptop installed with latest
version of remote software
(Supplied on CD)
• Copy of commissioning
checklist
• Correctly configured serial
lead
• Test Apparatus

14. • Correct use of a checklist will
ensure a standard
commissioning procedure is
carried out in every instance
and no aspects are
overlooked
Commissioning
Check List

15. The serial lead used to connect
the detector a PC is referred to
as a “Null Modem” cable, due to
its configuration
It is now common for laptops to
be supplied without a serial port,
several third-party devices are
available to convert a USB port
to a serial port, we recommend
using the UC-232A from ATEN.
Serial Lead

16. Hochiki promote the use of real
smoke in order to test the
FIRElink range of detectors,
“Canned Smoke” should not be
used.
Test Apparatus

17. • The FIRElink-400 supplied with
a back plate for ease of
installation
• The plate mounts to the wall
using the pre-drilled holes

22. • Various interfacing options
are available. A simple
installation may only utilise
the volt free contacts supplied
as standard
• Alternatively an A.P.I.C.
(Addressable Programmable
Interface Card) might be
used, which emulates a
device on the main fire panel
loop.
Interfacing

23. • Site, company and system
type details details should be
noted on the checklist
• Isolate the detector at the
main fire panel prior to
carrying out any work
• Ensure there is sufficient
access to the detector for
future maintenance
Pre Power-Up Checks
• Ensure the pipe work is
correctly installed, the
exhaust bung has been
removed and that all
necessary inlet bungs have
been removed

24. Air Filter
• Allow an 80mm
margin around the
outside of the
detector, this will
allow future access
to the air filter

all others must

26. • The following brief checklist
outlines a basic generic
configuration of any detector
in the FIRElink range
• This procedure will be
adequate for most standard
installations, for more
detailed programming
information refer to the
relevant installers handbook
and/or technical manual
Basic Configuration

27. The detector can now be
programmed via the front panel
….or using a laptop via
RS232
….or using a Command Module via
RS485
Basic Configuration

28. “Access” - After clicking the detector icon the you will be
prompted to enter the access code, the default code is “0102”
Basic Configuration

29. “Date & Time” - it is important to ensure a correct date and
time stamp on any events that occur for future reference.
Basic Configuration

30. “Alarm factor” - This is the sensitivity setting for the detector,
“0” being the most sensitive and “8” being the least sensitive.
Basic Configuration

31. Smoke
Density
Time
Fixed Sensitivity
The Sensitivity Level
must be set above
the highest ambient
level if false alarms
are to be avoided
The Sensitivity to a Fire
varies with changing ambient
smoke levels
Variable Ambient Smoke Level
Fixed Scaling

32. Smoke
Density
Time
Variable Ambient Smoke Level
Because FIRElink is a
RELATIVELY scaled
(sensitivity) detector, the
sensitivity to a FIRE remains
constant, regardless of
changing ambient conditions
Relative Scaling

33. Smoke
Density
Time
Variable Ambient Smoke Level
Our smoke density display
will only show a fluctuation
above ambient or “normal”
levels.
Relative Scaling

34. • Will Alarm at a fixed
smoke density level,
regardless of whether
smoke is ambient or
produced by a fire
• The sensitivity to a
Fire varies with
changing ambient
conditions
Fixed Sensitivity
• ClassiFire sets the
correct level of
sensitivity, based upon
the ambient smoke
level
• ClassiFire maintains
that sensitivity
regardless of changes
in ambient conditions
Relative Sensitivity

35. Conversely by setting the alarm factor to “8” the background
level is being tracked at a greater distance, nuisance alarms
will be extremely rare, however the detector will be
operating at a lower sensitivity.
If you are tracking the background level very closely (alarm
factor “0”) then you are providing very high sensitivity,
however nuisance alarms may be more frequent as a result.
The “Alarm factor” is the sensitivity setting for the detector, “0”
being the most sensitive and “8” being the least sensitive.
Basic Configuration

36. “Auxiliary Level” - The factory default value is 10, so this
relay will activate after Fire unless altered.
Basic Configuration

37. “Latching Alarms” – Do you wish the any fire conditions
to latch until reset at the front panel?
Basic Configuration

38. “Latching Faults” – Do you wish the any faults to latch until
reset at the front panel ? (Some detector options do not come
fitted with a reset button).
Basic Configuration

39. “Battery & Mains Check” – If the power monitoring
functions are not being used then they should be disabled
to stop faults from being generated.
Basic Configuration

40. “Day & Night Switching” – The level of background smoke
may vary from Day to Night, this transition can be set to
an approximate time…
Basic Configuration

41. ...or switched off altogether
Basic Configuration

42. …or switched manually when someone leaves the office
or activates a security alarm…
Basic Configuration

43. “Reset, Test & Isolate” - The front panel buttons can be
enabled or disabled depending on the environment, the
reset button is disabled by default…. ….so should be
enabled if you intend to have latching alarms or faults.
Basic Configuration

44. ...where a particular port is unused the sensor should be
disabled by un-ticking the box…
The FIRElink-400 features individual flow monitoring on
each inlet port…
...the ports are numbered 1 – 4 from left to right.
Basic Configuration

45. For each Inlet the “actual” flow is displayed, this cannot
be altered and should be approx 60 (+ or - 10)…
…if the reading is less than 30 or greater than 80 then
the pipe layout may require attention…
Basic Configuration

46. The low & high flow limits are set automatically during a
“flow setup”
The limits may also be set manually in order to allow for
larger fluctuations in flow.
Basic Configuration

47. …or increased to reduce transport times, altering the
aspirator speed will affect current consumption.
The aspirator speed on the FIRElink may be altered,
decreased to reduce noise levels…
Basic Configuration

48. The detector will carry out a FastLearn for
15-minutes
• After being powered-up,
• When a filter has been replaced or
• When the “Alarm Factor” has been
changed.
This is indicated by scrolling LEDs on the
smoke density display (FIRElink-400 range)
or a flashing “OK” LED (FIRElink-25 and
FIRElink-100).
FastLearn

49. During this 15 minute period the
detector will gather information - a
“snap-shot” of it’s surrounding
environment that will determine
the position of the alarm
thresholds.
The detector may be tested once
this period has elapsed, however it
will not reach full sensitivity for 24
hours unless “Demo Mode” has
been initiated.
FastLearn

50. Initiating “Demo Mode” causes
the detector to treat the 15
minutes worth of information it
has just gathered as a full 24
hour learn.
The detector can then
approximate the alarm
thresholds to a more sensitive
level for the purposes of
providing a realistic
demonstration of future
performance
FastLearn

51. Whilst a “FastLearn” is in progress “Demo Mode” may be
initiated by ticking the box and clicking “OK”.
Basic Configuration

52. 15 minutes, just enough time for a coffee!
Basic Configuration

53. After 15 minutes the LEDs will
stop scrolling (or flashing) - the
detector can now be tested.
Once the detector has been
tested the a new FastLearn
should be initiated to gather
data over a “true” 24 hour
period.
