Stratos-HSSD-2® is a highly sophisticated ‘next generation‘ of High Sensitivity
Aspirating Smoke Detection product that has been designed to ensure that installation
and commissioning is as simple as possible, while optimising performance.
Stratos 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.
Stratos 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.
Stratos has proven its worth many times by detecting ‘difficult-to-detect‘ slow growth
electrical overload incipient fires in ‘difficult‘ environments.
This handbook gives information likely to be needed for most installations, but for
more detailed information on subjects such as Fresh Air Referencing, please refer to the
complete Technical Manual or System Design Guide.
This equipment is Class 111 as defined in EN60950 (i.e., this equipment is designed to
operate from Safety Extra Low Voltages and does not generate any hazardous voltages).
This label is located on the laser chamber at the bottom right of the open detector and
signifies that the unit is a Class 1 Laser product as specified in IEC 60825-1. The unit
incorporates a Class 3B embedded laser which must not be removed from the detector
as retinal damage may result if the laser beam enters the eye.
As this equipment is part of a fire detection system, it should be supplied from an
approved power supply conforming to EN54-4.
This symbol appears on the main board of the unit and indicates that the board
contains static sensitive components. Suitable anti-static precautions must be taken
when handling the board, eg. for fuse replacement.
This symbol indicates the Safety Earth studs (see sections 1.3 and 1.4). These are for
grounding cable screens etc. and should not be connected to 0V or signal earth.
Kidde Products Ltd. has taken every care to ensure that Stratos is as simple to install
as possible but in case of difficulty, please contact our Help Line to ensure trouble free
installation and operation.
Kidde Products Ltd. takes no responsibility for damage or injury occasioned as a result
of failing to install or operate the equipment in accordance with these instructions.

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 section 1.2).
It may be programmed via the front panel as in the version shown above. Alternatively,
and for detectors ordered without front panel display, the detector may be pro-
grammed remotely via the detector’s RS485 terminals using a Command Module, or
via the detector’s RS232 port using a PC running Remote Control software. A copy of
this software is packed with each detector supplied.

detector
1. Types of
Detector
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 Stratos detectors connected to the detector loop.

Aux, Pre-Alarm, Fire 1 and Fire 2 indicators illuminate when the appropriate
alarm level has been reached and the appropriate time delays have expired.
On a stand-alone Command Module, the indicators signify an alarm
condition from any detector on the communications loop.
Smoke density indicators. This display is in two sections. The first part,
labelled 1 to 10, is the relatively scaled ClassiFire
®
bargraph 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 bargraph 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 bargaph display on the Command Module will mimic the
bargraph 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 3, ‘Programming
the unit‘ 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.

2.1, Types of display
The Standard Detector display is a two-line LCD which allows basic programming of
the detector.
The Command Module display contains more information than that for the Standard
Detector and prompts the user with the action expected by the use of graphic symbols.

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 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.
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.
, , . These buttons, also referred to in the text as menu
buttons or by name, e.g. <ENTER>, are used when programming the unit,
which is pass code protected. See section 3, ‘Programming the unit‘ for
more information.; Pressing
or when not in programming mode
(the access code has NOT been entered) will scroll through the detector’s
event log. See section 7 ‘Event log’ 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.

3. Programming
the unit
3.1 Engineering
Access code
The Stratos-HSSD-2 programmer means that programming and configuration of the
unit can be performed without opening the detector case.
To enter programming mode, press any of the program menu keys
, or .
This correctly sets the access code. If an incorrect access code is entered or <RESET>
is pressed, the display will show Bad access code. Pressing a menu key will prompt
the user again for the correct access code.
Access code:0000
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
, , . The unit responds by
displaying the prompt Access 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
has no effect until is pressed to place the cursor under the
first digit.
Access code:0000 Access code:0000
Access code:0100
Access code:0102
Access code:0100 Access code:0100
Access code:0101
All of the programmable functions work in a similar manner. The
keys move the
cursor position through the user-settable digits and the
keys step through
the available values for the currently selected digit (e.g. 1 - 99, Yes / No etc) pressing
enters the displayed figure. Note that it is not possible to save an illegal value, e.g.
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
Access timeout and exit programming mode.

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 3.5). 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 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).
Time and date and Relay 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
Bad detector will appear.
This message will also appear if the Command Module address “000” is entered into a
function which only applies to detectors, i.e. anything except “CM only” and “Address
000-127” functions.
3.4.1. 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 sec-
tion 3.7, “Event log” for more details. 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

3.4.3 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.
3.4.4. 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 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.
3.4.5. 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, e.g. semiconductor manufacturing clean rooms where airborne pollut-
ants 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 sensitiv-
ity 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 pro-
tected area has been set, nuisance alarms will be reduced to an absolute minimum.

3.4.2 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.

3.4.6 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, e.g. 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 that 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 compensat e for 1 hour seasonal time-changes.
3.4.7 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 No. 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.
3.4.8 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
Kidde Products Ltd.
Setting this function to Yes will start a FastLearn at any time. The bargraph display on
the front of the detector will 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 FastLearn 15 and will then count
down each minute until the FastLearn is complete.
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
24-hour learning period. To cancel demo mode, set this function to Yes or power
down and restart the detector to initiate FastLearn mode.

3.4.9 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 (e.g. 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 circumstances it may not
be desirable that the detector should to go through the whole learning process again.
To this end, this function can be set to No before power-down, where upon it will return
to the original settings on power-up.
3.4.10 Time Delay Override (Yes/No - Address 001-127)
Setup menu > Alarm actions
If this function is set to Yes, then the detector will ignore any pre-set time delays in the
event of an unacceptably rapid increase in smoke density, thereby minimising response
time to ‘rapid growth’ fires. This function would normally only be used where there
were long time delays programmed on the alarm levels.
3.4.11 Cascading alarms (Yes/No - Address 001-127)
Setup menu > Alarm actions
Setting this function to Yes means that only when the detector’s controller has gone
into Pre-Alarm does the controller start counting down the main Fire delay i.e. the time
delays on Pre-Alarm and Fire 1 are cumulative. The Aux alarm is not included in the
cumulative delay since it may be set to a higher level than either the Pre-Alarm or Fire
1 levels.
3.4.12 Latching alarms (Yes/No - Address 000-127)
Setup menu > Alarm actions
When this function is set to Yes it requires a reset on the front panel or a remote reset
to clear an alarm condition. It may be applied to the Command Module or a Standard
Detector.
