1. Introduction
1.1 General
AutroSense Micra 100is 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.
AutroSense Micra 100 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.
The AutroSense range of detectors 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.
The AutroSense range of detectors 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).
If this equipment is part of a fire detection system, it should be
supplied from an approved power supply conforming to EN 54-4.
1.2 About the reader
This handbook in intended for Autronica personnel authorized to install
the AutroSense Micra 100.

2. Indicators
1. The Fire indicator illuminates when the alarm level has been
reached and the appropriate time delays have expired.
2. The Fault indicator illuminates when the unit has a fault and a fault
signal is being sent to the fire alarm panel.
3. The OK indicator illuminates to show normal operation when there
are no faults. The OK lamp will flash during the 15 minute
Fastlearn period when the detector is first learning about its
environment.
