Before installing the detector the local standards for installation of aspirating detection
systems must be consulted as these standards differ throughout the world. Specific
advice for one country may not be applicable to another. The following is a brief set of
guidelines on installing detectors.
The detector will normally be mounted at a level where there is easy access to the

unit for configuration and programming.
The exhaust air from the unit must not be impeded in any way. If the unit is

mounted in a different air pressure from where the air is being sampled (for
example an air duct), then a pipe must be taken 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 screened and must be of a suitable type. 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 Radio Frequency levels (such as radio alarms) or units generating
high levels of electrical energy (such as large electric motors or generators).
The basic principle behind installation of the Micra is that all wiring and pipe-work is
installed using a docking station. This is a convenient feature which means that the
detector can be dismounted or replaced without disturbing any wiring or installed
pipe-work.
There are two types of docking station, one with a single inlet port for aspirating pipe-
work, the other with a second port allowing the detector exhaust air to be taken back
to the area of different atmospheric pressure from which the inlet is sampling (see
section 4, "Sampling Pipe Design", paragraph 1).
