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.

Introduction
WARNING: Electrocution hazard. To avoid personal injury or death from
electrocution, remove all sources of power and allow stored energy to discharge
before installing or removing equipment.
To install the detector:
1. Unpack the shipping carton. Ensure that the package contains a CD-ROM,
two ferrite rings, two cable glands, and the unit.
2. Determine the optimum location for the detector.
3. Mount the APIC or relay card inside the detector, if required.
4. Mount the docking station.
5. Connect the docking station to the sampling pipe network.
6. Mount the detector to the docking station.
Note: Each relay card is supplied with a RF suppression ferrite ring. To ensure
compliance with all relevant EMC requirements, conductors connected to the
fault output (included screen wire) should be wound once around a ferrite.
Antistatic precautions
Caution: Equipment damage hazard. This product is sensitive to electrostatic
discharge (ESD). To avoid damage, follow accepted ESD handling procedures.
This system contains static-sensitive components. Always ground yourself with a
proper wrist strap before handling any circuits. This recommendation must be
followed when removing the equipment case, and during installation, and
servicing.
Electrostatic discharge can be reduced by adhering to the following guidelines:
• Always use conductive or antistatic containers for transportation and storage,
if returning any item.
• Wear a wrist strap while handling devices and ensure that a good ground is
maintained throughout the installation process.
• Never subject a static sensitive device to sliding movement over an
ungrounded surface and avoid any direct contact with the pins or
connections.
• Avoid placing sensitive devices onto plastic or vinyl surfaces.
• Minimise the handling of sensitive devices and printed circuit boards (PCBs).

Stratos Micra 10 Aspirating Smoke Detector Installers Handbook 9
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 (see Figure 4).

Application
This detector is a smoke detector intended to provide localised incipient fire
detection. It is suitable for use in a wide range of applications, such as small non-
compartmentalised rooms, warehouse racking, or pieces of electronic or
electromechanical equipment where it is desirable to achieve individual incipient
fire reporting. In compartmentalised rooms, each compartment would normally
use individual aspirating detectors.
The detector employs a low-power aspirator (fan) designed to detect incipient
fires in relatively small areas. The detector is not intended to protect large areas,
or to sample from areas where there may be any difference in airflow rates or
pressure differentials. If detection in environments conforming to these
descriptions is required, other type detectors should be used.
System design
Simple designs with short sampling pipes produce the best results. Complex
sampling pipe runs should be avoided with the detector. The use of t-joint pipes
is not recommended. Maximum recommended sampling pipe length is 50 m
(165 ft.) in still air. If the protected area has airflow present, the maximum
permitted sampling pipe length will be reduced.
Caution: Ensure that the pipe network has been designed and its performance
verified using PipeCAD before installing pipes. See your PipeCAD
documentation for more information.
Sampling pipes must have capped ends. The end cap should be drilled with a
hole normally between 4 or 5 mm diameter and free from burrs. Sampling holes
should normally be 3 to 4 mm diameter (or as calculated by PipeCAD) and free
from burrs. Each pipe run should not have more than 10 holes (including the end
cap hole). Pipe transit time from the furthest sampling hole from the detector
must not exceed 120 seconds and an approved type of pipe must be used. It is
strongly recommended that the smoke transit time from the furthest sampling
hole be checked during commissioning tests.
Capillary remote sampling points may be used in place of sampling holes.
Always locate the sampling points in positions to which smoke may reasonably
be expected to travel. It is usually better to locate the sampling pipe directly in the
airflow (for example, across the return air register of an air conditioning unit).
Note: There is no substitute for carrying out smoke tests prior to installation of
pipework to indicate suitable sampling point location.
No more than one air handling unit may be protected with one detector. In this
application, ensure that the sampling pipe is raised clear of high velocity air in the
immediate vicinity of the air intake grill on standoff posts as shown in Figure 5.

Below or above the ceiling installations
The detector is supplied with a docking station (as shown in Figure 4 on page
10). This allows the detector to sample from areas which may be at different air
pressure from the detector location. Typical uses are for air duct sampling and
allowing the installation of the detector in under-floor or ceiling voids or when
sampling from pieces of computer related equipment (see Figure 6 and Figure 7).

Table 2 below contains a list of procedural guidelines for installation of the
detector.
Table 2: Procedural guidelines
Do
Don’t
Ensure that the power and signal cables are
correctly connected before powering up by use
of cable
identifiers or electrical continuity
checks. Incorrect connection could damage the
detector.
Ensure that cable of an appropriate approved
type is used for interconnection.
Place sampling points so that the detector will
be able to detect smoke at the earli
est
opportunity.
Ensure that the detector exhaust is in an area
with the same atmospheric pressure as the
sample pipes, either by placing the detector
physically in the protected area or by leading a
pipe from the detector exhaust to the protected
area.
En
sure that the environment of the protected
area is within the environmental operating
parameters of the detector.
Set the appropriate ClassiFire alarm factor for
the area to be detected.
Set the detector address s
witches correctly
when used in a network.
E
nsure that the detector is properly grounded.
Drop the detector.
Install detectors in damp or exposed areas.
Remove or connect boards when the detector is
powered up.
Connect internal 0 volt terminals to local earth.
Attempt to re-use dust separator (filter)
cartridges once removed.
Attempt to adjust or alter detector settings other
than via the user-programmable functions. Any
attempts to adjust the laser potentiometer are
detectable and will void the warranty on the
product.
Place the detector near high power RF sources.
Place the detector so close to other equipment
that there is insufficient room to access and
change the dust separator (filter) or access the
RS-232 connector.
Use sampling pipe of less than 27 mm (1 in.)
outside diameter without a suitable 27 mm
(1 in.)
pipe adapter. It is important that there are
no leaks where the pipe connects to the
detector.
Use excessive force when fitting sampling pipes
as this may damage the detector.
