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 6.9V to 9V 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
