19
Serial Lead
Installation Commissioning

• 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 the CN-116 from
Sitecom.

Interfacing

• 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.

Installation Commissioning

• APIC Card

• Detector On-Board Relays

28
Interfacing

• The Alarm relays are N/O, closing on alarm
• The Fault relay is N/C, opening on fault
• The onboard relays are volt free and rated at
  10VA
• this equates to 400mA _at_ 24Vdc.
• It is worth noting that the current rating
  stated on most beacons / sounders is the
  quiescent, these devices can have in-rush
  currents in excess of 3A!
• It is a wise precaution to use a 47ohm resistor
  in series to limit current draw.

29
Pre Power-Up checks

• Site, company and system type details details
  should be noted on the checklist.

Installation Commissioning

• 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.

30
Sufficient Access
Installation Commissioning

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

..the serial port.
and the detector housing.
31
Pre Power-Up checks

• 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.
• Ensure the pipe work is correctly installed, the
  exhaust bung has been removed and that all
  necessary inlet bungs have been removed.

Basic Configuration

• The following brief checklist outlines a basic
  generic configuration of any detector in the
  Stratos 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.

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

Access - After clicking the detector icon the
you will be prompted to enter the access code,
the default code is 0102

Date Time - it is important to ensure a
correct date and time stamp on any events that
occur for future reference.
37

Alarm factor - This is the sensitivity setting
for the detector, 0 being the most sensitive
and 8 being the least sensitive.
38
Fixed Scaling
It is important to understand how the sensitivity
is set, the main obstacle for reliable operation
of such a high sensitivity detection system is
the interpretation of any background pollution
either genuine smoke and /or fine particles that
would be seen as smoke
.our competitors use Fixed Scaling, this means
they determine the highest point to which the
background smoke will riseand then fix the
alarm threshold above this level
Installation Commissioning
39
Fixed Sensitivity
Relative Scaling
Because Stratos-HSSD is a RELATIVELY scaled
(sensitivity) detector, the sensitivity to a FIRE
remains constant, regardless of changing ambient
conditions

Our smoke density display will only show a
fluctuation above ambient or normal levels.

42
Basic Configuration
Installation Commissioning
The Alarm factor is the sensitivity setting for
the detector, 0 being the most sensitive and
8 being the least sensitive.
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.
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.

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

buttons can be enabled or disabled depending on
the environment, the reset button is disabled by

..where a particular port is unused the sensor
should be disabled by un-ticking the box

The Stratos-HSSD 2 features individual flow
monitoring on each inlet port..

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

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.

.or increased to reduce transport times,
altering the aspirator speed will affect current
consumption.
The aspirator speed on the Stratos-HSSD 2 may be
altered, decreased to reduce noise levels.
53
FastLearn
Installation Commissioning
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 or a flashing
OK LED.
54
FastLearn
Installation Commissioning
During this 15 minute period the detector will
gather information.. a snap-shot of its
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.
55
FastLearn
Installation Commissioning
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
56
Basic Configuration

Whilst a FastLearn is in progress Demo Mode
may be initiated by ticking the box and clicking
OK.

15 minutes, just enough time for a coffee.!
58
FastLearn
Installation Commissioning
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.
