Product Description

Aspirating smoke detectors from the FCS-320-TM series are active fire detection devices for
providing early smoke and fire detection. They are used for space and equipment protection
as well as for monitoring air conditioning units or ducts (provided that the FCS-320-TM is
installed outside of these units or ducts). You can also pinpoint the exact location of the fire
using the innovative fire source identification operation.
Variants
All FCS-320-TM series aspirating smoke detectors have LED displays for operating mode,
malfunction and main alarm, and also offer an infrared diagnostics port. In addition, the FCS-
320-TM-R variant offers an optical fire source identification display for up to five zones.
fire source identification
Innovative fire source identification technology allows the exact location of the fire to be
pinpointed by monitoring up to five distinct neighboring zones. To enable the emergency
response teams to intervene as quickly as possible, the location of the fire can also be
identified, for example, by means of strobes that are assigned to the various monitoring
ranges.
sensitivity
FCS-320-TM series aspirating smoke detectors have a response sensitivity of 0.5%/m to 2%/m
light obscuration.
With the new high-power light source technology, a broad detection spectrum including all
standardized fires is achieved (see Section 3.4 Defining the Response Sensitivity, page 35).
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-TM series reliably detect
malfunctions such as pipe breakage or obstruction of the air sampling openings.
The airflow monitoring is temperature-compensated and can be set depending on the air
pressure.
Plug-and-play
The plug-and-play function makes the installation and commissioning of the aspirating smoke
detectors simple. The housing base is preinstalled on site. By presetting the detection unit for
standard applications, the FCS-320-TM series aspirating smoke detectors are ready for
operation as soon as they are inserted into the housing base.
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.
