Installing the Detector Module
See
Figure 3, Page 4
:
1.
Open the unit by carefully unlocking the housing cover's quick-release locks with a
screwdriver and then removing the housing cover.
2.
Carefully disconnect the display board connection cable from the motherboard ("DISPL."
connection) and remove the housing cover.
1.
Spread the brackets provided for fixing the detector module slightly apart.
2.
Carefully insert the detector module until you hear it click into place. Make sure that the
used detector module is fixed tightly and securely by the bracket by additionally pushing
together the brackets by hand.
3.
Connect detector module 1 to the "HEAD1" connection on the motherboard using the
flatband cable.
FCS-320-TP2 and FCS-320-TT2 variants:
Connect detector module 2 to the "HEAD 2" connection on the motherboard using the
flatband cable.
4.
Reconnect the display board connection cable to the "DISPL." connection on the
motherboard.
Setting the Fan Voltage
See
Figure 4, Page 5
: with jumper JU1, the fan voltage is set on the motherboard. The default
setting is marked in bold.
Number of Detector Modules
See
Figure 4, Page 5
: The number of populated detector modules is factory set in line with the
model variant (jumper JU4 on the unit's motherboard).
Installing the Unit
NOTICE!
Only DM-TP-50(80), DM-TP-10(25) and DM-TP-01(05) detector modules certified to VdS may
be used in the FCS-320-TP1/TP2. Only DM-TT-50(80), DM-TT-10(25) and DM-TT-01(05)
detector modules certified to VdS may be used in the FCS-320-TT1/TT2.The detector module
settings are configured via the DIP switch on the detector module.The sensitivity value is
based on measurements with standard test fires (old value in brackets).
NOTICE!
FCS-320-TP2
and
FCS-320-TT2
variants
:
These units are factory prepared for the installation of two detector modules:
-
The fan covers for both aspiration pipes are removed.
-
The two pipe system connections are cut out.
-
The pin pair on jumper JU4 is open (see
Figure 4, Page 5
).

NOTICE!
-
When selecting the installation location, ensure that the unit displays are easily visible.
-
Remember when planning that the unit fans generate a noise level of approx. 45 dB(A).
-
The air outlet on the unit must not be obstructed. The distance between the air outlet
and adjacent components, e.g. a wall, must be at least 10 cm (4 inches).
-
The aspirating smoke detector can be installed with the suction device pointing up or
down (to do this, rotate the housing cover through 180°). If the aspiration pipe points
down, make sure no impurities enter the air return pipe, which will be pointing up.
-
The aspirating smoke detector is either screwed directly to the installation wall by the
rear panel or installed using unit mounting type MT-1, e.g. on frames (see
Figure 5,
Page 5
: 1 = horizontal installation, 2 = vertical installation).

1.
First, clearly mark the fixing points on the installation position provided on the
equipment. Use the supplied drilling jig as an aid. To guarantee a firm, low-vibration hold,
the unit must be secured with four screws (max. 6 mm
∅
(0.4 inches) for wall mounting,
max. 4 mm
∅
(0.2 inches) for MT-1 unit mounting).
2.
Using four screws appropriate for the installation method, attach the unit securely to the
surface or to the unit mounting. Ensure that the unit is not fixed under mechanical stress
and that the screws are not tightened too tightly, otherwise damage or undesirable
resonance noises could occur.
To balance out unevenness and/or prevent vibrations, vibration absorbers (subject to
separate order) must be used.
3.
Using a screwdriver, carefully punch out the required cable entries on the housing (max.
5 x M20 and 2 x M25).
4.
Fit the cable entry/entries as required with M20 or M25 connections (2 x M25 and 1 x
M20 included in the delivery) by pushing them into the cable entry/entries.
5.
Route the connection cable(s) (max. 2.5 mm
2
) through the prepared M20 or M25
connections and into the unit. Cut them to the required length inside the unit.
6.
Wire the unit according to the connection information described below.

1.
Check the system after installation using the FAS-ASD-DIAG Diagnostic Software.
2.
The unit must be operated for at least 30 min prior to the airflow being initialized to bring
it up to operating temperature.
3.
To initialize the connected pipe system, press the S2 flow-init button (see
Figure 5,
Page 5
) on the detector module concerned until the green operating LED on the unit
starts to flash. Initialization is complete after approx. 10 seconds. Following successful
initialization, the operating LED lights up permanently.
4.
No further modifications may be made to the pipe system during or after initialization.
The unit's fan voltage must also remain unchanged following initialization. Otherwise, the
initialization procedure must be repeated.
Troubleshooting Using Flash Codes
