3 Technical Specifications
3.1 Product Description
Aspirating smoke detectors from the FCS-320 series are active fire detection devices that are
connected directly to conventional lines for early smoke and fire detection. They are used for
room and equipment protection as well as for monitoring air-conditioning units or ducts.
Variants
The FCS-320‑TP1 and FCS-320‑TP2 models feature LED displays indicating operating mode,
malfunction and alarm (the FCS-320‑TP2 has two alarm displays). The FCS-320‑TT1 and
FCS-320‑TT2 models offer differentiated alarm displays (info, pre and main alarm) as well as a
10-level smoke display (on the FCS-320‑TT2, all alarm and smoke level displays are doubled).
The FCS-320‑TP1 and FCS-320‑TT1 variants are each fitted with a detector module.
Both FCS-320‑TP2 and FCS-320‑TT2 have two integrated detector modules each. Two
aspiration pipes can be connected, enabling two areas to be monitored. This effectively
doubles the monitoring area.
Dual-detector dependency
The use of two detector modules in variants FCS-320-TP2 and FCS-320-TT2 also enables a
dual-detector dependency to be realized. This means that one area can be monitored by two
pipe systems.
Two alarm stages
Alternatively, the FCS-320-TP2 and FCS-320-TT2 can have two alarm stages configured. A pipe
system is connected via a pipe adapter on two detector modules. Selecting different response
sensitivities for the detector modules enables the time-staggered triggering of two main
alarms.
Sensitivity
Three detector module versions are available for the FCS-320 aspirating smoke detector
series:
– DM‑TP‑50(80) with a response sensitivity of up to 0.5%/m (0.8%/m) light obscuration
– DM‑TP‑10(25) with a response sensitivity of up to 0.1%/m (0.25%/m) light obscuration
– DM‑TP‑01(05) with a response sensitivity of up to 0.015%/m (0.05%/m) light obscuration.
Depending on the detector module used, the FCS-320‑TT1 and FCS-320‑TT2 models can
achieve a resolution ten times higher for displaying up to 0.05%/m (0.08%/m), 0.01%/m
(0.025%/m) or 0.0015%/m (0.005%/m) light obscuration.
Notice!
The sensitivity value is based on measurements with standard test fires (old value in
brackets).
The new High-Power-Light-Source technology permits a broad detection spectrum over all
standardized fires.
LOGIC×SENS
The intelligent signal processing LOGIC·SENS distinguishes between deception variables and
fire events in order to prevent false alarms.
Reliable airflow monitoring
Analogous to point-type smoke detectors, which are monitored electronically for wire breaks
and short-circuits, highly sensitive and dependable airflow monitoring is required for smoke
aspiration systems. The airflow sensors used in the FCS-320 series reliably detect
malfunctions such as pipe breakage or obstructions in the air sampling openings.
Airflow monitoring is temperature-compensated and can be set depending on the air pressure.
Aspirating Smoke Detector Technical Specifications | en 9
Bosch Sicherheitssysteme GmbH Operation Guide 2018.04 | 2.0 | F.01U.130.926
The small airflow unit also contains a dynamic airflow sensor that enables a response to small
and fast changes in the airflow.
Patented air sampling openings
The air sampling openings of the pipe system require clearly defined bore diameters that
depend on the planning and design. These precise air sampling openings are created using
patented aspiration reducing film sheets, marking tape, and clips, which not only permit easy
installation, but also prevent "whistling" noises. Another advantage is the quick and easy
detection and checking of the air sampling opening diameters.
Point-type detector projection
The system’s aspiration points can be equated with point-type smoke detectors. The
monitoring areas can therefore be planned in accordance with the applicable national
regulations.
Diagnostics
There is a system available with the FAS-ASD-DIAGdiagnostic software that enables quick and
convenient error containment for maintenance and service. The current and stored unit status
is read out via cable data transmission to the PC.
Selecting the fan voltage
The fan voltage for special planning can be increased from 6.9V to 9V by relocating the fan
jumper. This increases the air transport speed and therefore reduces detection time.
3.2 Areas of application
Thanks to their detection principle, FCS-320 aspirating smoke detectors represent an
extremely versatile fire protection solution.
Principle
Air samples are taken from the monitoring range by a pipe system with defined aspiration
borings and then fed to the detection module.
This is especially well-suited for areas in which point-type detectors cannot be used or can
only be used under certain circumstances. These include:
– Areas that are difficult to access, in which point detectors are difficult to install and
maintain
– Air-conditioned areas
– Areas that require the earliest detection possible
– Areas with a height greater than that allowed for point detectors
– Areas in which point detectors are not desired for aesthetic reasons
– Areas in which strong electromagnetic fields occur
– Areas that are exposed to high or low temperatures
– Areas with contaminated air that require filter elements
– Areas that must be protected against vandalism.
Space protection
The FCS-320 series is suitable for monitoring areas such as
– Those with double floors, false ceilings
– Tunnels, ducts, barely accessible hollow spaces
– Storage, high-rise warehouses, elevator shafts
– Museums, cultural institutions
– Hotel rooms, hospital rooms, offices, prison cells, train compartments
– Freezer storage

Thanks to its high sensitivity, expensive goods and equipment can be monitored reliably. The
aspirating smoke detectors from the FCS-320 series are therefore especially suitable for areas
of application:
– Where early intervention is essential due to a high value concentration
– Where equipment must always be operational
– Where highly sensitive detection is necessary (e.g. in areas where, due to built-in filter
elements, the air contains a low concentration of smoke particles)
– Where high air-exchange rates prevail.

3.3 System Overview
The smoke aspiration systems comprise an aspirating detector and pipe system.
The aspirating smoke detector comprises the detector module for detecting the smoke
aerosols, the aspiration unit for transporting the air samples to the detector module and the
airflow sensor for monitoring the pipe system for breakage and obstructions.
The pipe system comprises essentially pipe and fittings. The standard pipe system is made
from PVC or ABS. The pipes used for equipment monitoring should be halogen-free.
Each air sampling opening in the pipe system represents a point detector in the planning.

To guarantee reliable operation even under the most difficult conditions (clean rooms,
recycling area), there are numerous accessories available, such as air filters, water separators
and detonation safety barriers.
3.4 Functions
Air samples are taken from the area to be monitored via the aspiration unit. They are fed via a
pipe system with defined air sampling openings to the sensitive detection module.
Detector module
Depending on the response sensitivity of the detector module in use and programmed alarm
threshold, the FCS-320 series aspirating smoke detector triggers the alarm when the
corresponding light obscuration threshold is reached. With the FCS-320‑TP1 and the
FCS-320‑TP2, the alarm is displayed via the alarm LED and/or two alarm LEDs on the unit and
transmitted to a connected fire panel. The FCS-320‑TT1 and FCS-320‑TT2 versions offer
differentiated LED displays for info, pre and main alarm. Pre and main alarms are transmitted
to the fire panel (with FPA‑5000 Rel 2.1; additionally with info alarm from Rel 2.5 or above).
Various delay times can be programmed for the alarm thresholds, as well as for displaying and
transferring malfunctions. Alarm messages are saved and are reset after the cause has been
eliminated.
LOGIC·SENS
Aspirating Smoke Detector Technical Specifications | en 13
Bosch Sicherheitssysteme GmbH Operation Guide 2018.04 | 2.0 | F.01U.130.926
The LOGIC·SENS intelligent signal processing compares the measured smoke level with
known disturbance variables and decides between alarm and deception.
Detector module monitoring
Each detector module is monitored for contamination, signal malfunction and removal. Soiling
of the detector module has no effect on its sensitivity. With all variants, any malfunction is
displayed via the malfunction LED and transferred to the fire panel. Malfunctions caused by
brief environmental fluctuations can be eliminated with a time-delayed setting.
Airflow Monitoring
An airflow sensor checks the connected pipe system for breakage and obstruction.
The airflow sensor can – depending on the configuration of the pipe system – detect at least a
50% obstruction to a complete obstruction of the air sampling openings and a breakage in the
pipe system that results in a 50% loss from the air sampling openings. Should the fan fail, the
airflow in the pipe system is interrupted and this causes a blockage message. Airflow
monitoring is temperature-compensated and can be set depending on the air pressure.
On expiry of a defined delay, the malfunction is displayed on the aspirating smoke detector
and the message is transmitted to the fire panel. The monitoring window thresholds can be
modified to suit the environmental conditions (see Airflow Monitoring).
The principal signal curve of the airflow sensor is indicated in Airflow Monitoring.

Fault Indication
An imminent detector module or airflow malfunction generates a malfunction message that is
displayed on the FCS-320.
Flash code for malfunction detection
Malfunctions and certain device statues are displayed using various LED flash codes on the
detector module's electronics PCB. Thus it is possible to differentiate quickly among
malfunctions that can be caused by a defective detector module, an obstruction, or a break in
the pipe system.
Resetting via fire panel
A malfunction message is reset via the connected fire panel. The panel resets alarm and
malfunction messages on the unit while simultaneously resetting the detector line via the
reset board.
Calibrating the airflow sensor
Automatic airflow sensor calibration makes it significantly easier to start the FCS-320. The
initialization phase is carried out according to or independently of the air pressure as desired.
14 en | Technical Specifications Aspirating Smoke Detector
2018.04 | 2.0 | F.01U.130.926 Operation Guide Bosch Sicherheitssysteme GmbH
To set the FCS-320 to the airflow typical for the pipe network, an airflow initialization (flowinit) procedure is carried out. This must be done for each unit once at the start after
installation, each time the pipe system is replanned/redesigned and after changing the fan
voltage. This enables the unit to determine and save the airflow typical for the pipe network.
Pipe System
A pipe system with an overall length of up to 300m can be connected to FCS-320 series
aspirating smoke detectors over a maximum of 32 aspiration points. Two pipe systems can be
connected to both the FCS-320‑TP2 and FCS-320‑TT2 variants. The entire pipe system then
has a total length of 2 x 280m and a maximum number of 2 x 32 aspiration points.

3.5.5 FAS-ASD-DIAG Diagnostic Software
DIAG
Figure3.4: Diagnostic software for reading out unit status
The diagnostic software enables the saved and the current unit status, as well as the error
messages to be displayed on the PC or laptop.
The supplied diagnostics cable connects the aspirating smoke detector ("DIAG" connection on
the motherboard) to the PC. The FAS-ASD-DIAG version is connected to the PC via a USB port,
earlier DIAG versions via a COM port.
Diagnostic messages remain saved in the unit for at least 3 days in order to be able to evaluate
even short, sporadically occurring errors (e.g. in case of changed operating conditions).
Resetting the device via the diagnostic software deletes all saved diagnostic messages.
The software also allows the deletion of error messages.
Notice!
The diagnostic software can be used to save in file format all the stored and current
diagnostic data as well as any settings made. To be able to compare the data read out, save
each file under a different file name.
3.5.6 Remote indictors
A remote indicator must be connected if the aspirating smoke detector is not directly visible
or has been mounted in false ceilings or floors.
The external detector alarm display is installed in an obvious place in halls or entrances of the
building section or areas concerned.

4 Vibration absorbers
Vibration absorbers
The fans of the aspirating smoke detectors cause a noise level of approx.45dB(A). Mounting
the FCS-320 onto vibration absorbers can effectively reduce noise transmission through the
installation elements. This results in a reduction in the noise level from 1to 2dB(A).
Additional operating noises may be caused by vibrations on the pipe system, which are
generated by the air flowing through it. This can be remedied by inserting a corrugated hose
(approx.15cm long) between pipe system and aspirating smoke detector to create a flexible
transition.
In noise-sensitive areas, the sound level can also be reduced by installing a piece of plastic
pipe approximately 100mm long into the air outlet opening of the unit. This is done by
breaking out the pre-punched opening in the protective grille (e.g. using a small edge cutter).

During planning/design, a distinction is drawn between area monitoring and equipment
monitoring. For both applications, PVC pipes and halogen-free pipes can be used but the
restrictions of EN 54.20 must be observed. The pipes used for equipment monitoring should
be halogen-free.
The figure shows essential accessory components that can be selected for the application
concerned.
The pipe system must be constructed using pipes with an external diameter of 25 mm and the
associated fittings.
If the maximum permissible pipe lengths are used, then for the pipe returns, pipes with an
exterior diameter of 40mm and the appropriate fittings must be used.
Blowing-out system
In areas that are susceptible to dust particles or icing, it may be necessary to blow out the
aspiration pipe system and its air sampling openings. The figure below shows a manual
blowing-out system with a three-way tap.

Aspiration reducing film sheets
An air sampling opening is a 10mm bore in the aspiration pipe that is covered with a patented
aspiration reducing film sheet with the required opening diameter. The size of the opening
depends on the structure of the pipe system (see Planning).
The aspiration reducing film sheet is secured with marking tape to prevent it from becoming
displaced. The marking tape is a transparent sticky film with red edges and a 10 mm hole. It is
placed over the aspiration reducing film sheet so that the air sampling opening is not
concealed and can be seen from long distances.

2 ASD aspiration clip made of
plastic
During use in deep-freeze areas, the flexible aspiration reduction expands in the air sampling
openings and pushes the ice away during blowing out. The special plastic clip ensures that the
aspiration reduction remains at the defined location.
As the clips are more stable under pressure and the elastic rubber insert significantly
improves the cleaning effect, they are used for all plans and designs which require a blow-off
system due to environmental influences (e.g. increased exposure to dust).
Notice!
The standard AF-x aspiration reducing film sheets and the marking tapes are not suitable for
use in low-temperature areas.
The aspiration reductions with plastic clips are available separately.

A concealed pipe system for area monitoring can be realized by installing in a false ceiling.
This requires the use of ceiling lead-throughs in the false ceiling. The ceiling lead-through can
be used with a false ceiling thickness of up to approx. 35mm.According to the planning and
design guidelines, the ceiling lead-throughs are fitted with aspiration reducing film sheets with
defined air sampling openings and connected to the pipe system by means of aspiration
hoses.
If these hoses exceed a maximum of 1m in length, the plan according to Section3Planning
applies. If structural circumstances dictate that lengths in excess of 1m are used, the pipe
system has to be calculated accordingly.

If the aspirating smoke detectors and the pipe system are installed in areas with varying air
pressure, the aspirated air must be returned to the pressure area of the pipe system. The airreturn pipe can serve to equalize pressure or to prevent atmospheric loads (e.g. odors) in
neighboring spaces.

out.
!
Caution!
The air-return pipe of the smoke aspiration system should not exceed 2m. Longer returns
must be checked individually.

3.6.5 Air filters for dusty areas
In areas with interference to the environment such as, e.g. dust, an air filter is to be used to
protect the smoke detection system. The standard air filter used is the type FAS-ASD-FL,
consisting of a plastic housing with two pipe connections. If the air filters are dirty, then the
filter inserts must be changed by opening the filter housing.
In order to extend the maintenance intervals, one air filter can be installed in every output
pipe instead of one air filter inside the main sampling pipe. The same design specifications
shall apply as stated in the projection tables in the appendix.
FAS-ASD-FLFAS-ASD-FLFAS-ASD-FLFAS-ASD-FL
FAS/FCS
Furthermore, in order to extend the maintenance intervals, several air filters can be installed
in parallel in the main sampling pipe. This requires the main sampling pipe to be split into one
or several pipes and to be equipped with the same air filter or the combination of air filters.
The individual pipes can then alternatively be either combined again to one main sampling
pipe or be separately continued into the monitoring area(s). The same design specifications
for the individual air filters shall apply as stated in the projection tables in the appendix.
3.6.6 Water Separator for Humid Areas
If the smoke aspiration system is operated in environments where condensate can form in the
aspiration system, a water separator is used. Condensate can form with sharp temperature
fluctuations and in areas where fresh air is monitored.For areas with extremely high humidity,
the FAS-ASD-WS Water Separator can be used, for example.
The FAS-ASD-WS Water Separator is integrated at the lowest point in the pipe system
downstream of the air filter and the aspirating smoke detector. The 45° pipe elbow permits
optimum distance from the wall.

7 Detonation safety barrier
Vapor/air and/or gas/air mixture ignition in the aspirating smoke detector may result in pipe
explosion or detonation. This depends on the composition, concentration, temperature, and
pressure of the flammable mixture.
The detonation safety barrier is a flame trap that is flame-proof in the face of pipe explosions
(deflagrations) and detonations.
26 en | Technical Specifications Aspirating Smoke Detector
2018.04 | 2.0 | F.01U.130.926 Operation Guide Bosch Sicherheitssysteme GmbH
In normal operation, the steam and gas mixtures flow in any direction through the safety
barrier. An ignition of the mixture in the upstream aspirating smoke detector will cause the
developing detonation to be arrested. Ignition is prevented by the flame filter. Combustion of
the mixture in the flame filters may cause a rebound of the detonation front. To prevent this, a
minimum pipe length of 1.0m between the installation point of the detonation safety barrier
and a possible ignition source (aspirating smoke detector) must be maintained. Permanent
fire prevention is thus achieved indirectly.
!
Caution!
The connecting pipe between the aspirating smoke detector and the detonation safety barrier
must be made of metal. During installation, care must be taken to ensure that the threaded
connections are bolted together gas-tight using synthesol or sealing tape.
