Installation and configuration
10 AutroSense Micra 10 Aspirating Smoke Detector Installers Handbook
General installation guidelines
The following is a brief set of guidelines on installing detectors:
• The detector should normally be mounted at a level where there is easy
access to the RS -232 serial port for configuration and programming.
• The exhaust air from the unit must not be impeded in any way. If the unit is
mounted where the air pressure differs from the sampling location (for
example an air duct), then a pipe must be routed from the exhaust port back
to the same air pressure zone as the sampling holes.
• Sampling holes should be free from burrs and swarf.
• All signal cables must be suitable for the application. The specific type of
cable will normally depend upon the local fire regulations.
• The unit must not be placed in areas where either the temperature or humidity
is outside the specified operating range.
• The unit should not be placed in close proximity to any equipment expected to
generate high levels of radio frequency signals (such as radio alarms) or units
generating high levels of electrical energy (such as large electric motors or
generators).
Docking station
The basic principle behind the easy installation of the detector is that all wiring
and pipework is installed using a docking station. This is a convenient feature
that allows the detector to be dismounted or replaced without disturbing any
wiring or installed pipework.
The docking station inlet (sampling) port and exhaust port is used to interface
with the pipe network. The inlet port is used for aspirating the pipework network.
The exhaust port allows the detector exhaust air to be routed back to the
sampling area, when differing atmospheric pressures require this. (Refer to
Figure 4.)
