interruption, loss of data, or any other indirect, special, incidental, or
consequential damages under any theory of liability, whether based in contract,
tort, negligence, product liability, or otherwise. Because some jurisdictions do not
allow the exclusion or limitation of liability for consequential or incidental
damages the preceding limitation may not apply to you. In any event the total
liability of UTCFS shall not exceed the purchase price of the product. The
foregoing limitation will apply to the maximum extent permitted by applicable law,

Advisory messages
Advisory messages alert you to conditions or practices that can cause unwanted
results. The advisory messages used in this document are shown and described
below.
WARNING: Warning messages advise you of hazards that could result in injury
or loss of life. They tell you which actions to take or to avoid in order to prevent
the injury or loss of life.
Caution: Caution messages advise you of possible equipment damage. They tell
you which actions to take or to avoid in order to prevent the damage.
Note: Note messages advise you of the possible loss of time or effort. They
describe how to avoid the loss. Notes are also used to point out important
information that you should read.
Product Symbols
This symbol appears on the main board of the unit and indicates that the
board contains static sensitive components.
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.
This symbol indicates the Safety ground studs. These are for grounding
cable screens, etc., and should not be connected to 0V or signal earth.

EN 54-20 and UL installation
The installation must be designed using PipeCAD software. After designing the
installation including pipes, endcaps,and sampling holes, enter the detector type.
To select the detector type, click Options > Calculation options, and then select
the detector from the Type drop-down list.
EN 54-20 installation
Select Options > Calculate, or click on the calculator icon. The software will
prompt you to choose from Use set hole sizes, Best flow balance, and Max.
permissible transit time.Select the appropriate option and click OK. The results
for each pipe (View > Results) show calculations for each sampling hole on the
pipe with the nearest to the detector at the top of the screen, and the endcap
hole at the bottom.
For EN 54-20 compliance the transport time of the last sampling hole shall be
checked following all installation and proven to be less than or equal to that
determined by PipeCAD.
For the installation to comply with EN 54-20 Classes A, B, and C each sampling
hole must be no less sensitive than 0.31% obs/m.
The calculation can be further refined by leaving a working detector in the
protected area for at least 24 hours at the intended alarm factor for the
installation (this could be done before or after installation). The detector
sensitivity can be read from the Sensitivity figure on the histogram screen of the
Remote Control software supplied with each detector. Click Options > Calculation
options to open the Hole calculation options dialog box. Enter the sensitivity
value obtained from the practical test, and then click OK. The new calculated
value will use the real sensitivity from the practical test.
The PipeCAD software will determine the classification of any used configuration.
Commissioning and periodic system tests must involve smoke tests to verify that
the system performs as expected and enters Fire 1 alarm within the time
determined by PipeCAD from the farthest hole. The detector sensitivity must also
be inspected to ensure it has not radically fallen from the installed figure. If it has
changed for any reason, the new figure must be re-entered into PipeCAD and the
recalculated hole sensitivities must be 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.
UL installation
Note: UL certified products may also contain additional approvals, e.g. FM.
Please refer to the product labels.

vi Stratos Micra 10 Aspirating Smoke Detector Installers Handbook
UL 268 fire tests were passed with an installation as follows:
Total sampling pipe length: 160 ft. (single pipe)
Number of sampling holes: 10
Worst-case sampling hole sensitivity as indicated by PipeCAD:
1.28% obs/ft.*
Alarm factor: 1
Fire 1 alarm delay: 0 seconds
These settings gave satisfactory responses to the test fires in 120 seconds or
better. For the purposes of UL 268 compliance, these should be regarded as
worst case values. Layouts should be planned in PipeCAD and the indicated
worst-case hole sensitivity should be better than 1.28% obs/ft.*. Commissioning
smoke tests should be performed to ensure that the farthest sampling hole from
the detector is capable of generating a fire alarm within 120 seconds of receiving
smoke.
* The results should be verified at installation by entering the installed detector's
Fire 1 sensitivity (as indicated in the remote software histogram screen) into the
PipeCAD “Options/Calculation options/Detector sensitivity” field and recalculating
the layout results.

2 Stratos Micra 10 Aspirating Smoke Detector Installers Handbook
Introduction
This aspirating detector is a highly sophisticated next generation high sensitivity
aspirating smoke detection product that provides all the benefits of air sampling
high sensitivity smoke detection, including very early warning. Designed for easy
installation and commissioning, the detector 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 various
environments.
This detector operates by drawing air from a protected space via a supervised
piping network in relatively small areas. The sampled air is passed through a
dust separator (filter) to remove dust and dirt before entering the laser detection
chamber. State-of-the-art electronics are used to analyse the sampled air and
generate a signal representing the level of smoke present.
ClassiFire intelligence also monitors the detector chamber, continually adjusting
the appropriate operating parameters to counteract the negative effects of any
contamination. Aspirating smoke detectors are 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.
Available software for the detector
The Remote Control software package is available to program the detector.
•Remote Control software: Provided free of charge with every detector, this
software package enables the user to set up and configure the programmable
functions of one or more detectors from a computer connected via an RS-232
serial cable.
