Dynamic airflow

Activation or deactivation of dynamic airflow is possible via the diagnostic software.
Detection module
5.5.8 ROOM·IDENT
Activation or deactivation of fire source identification is possible via the diagnostic software.
Detection module
5.5.9 LOGIC·SENS
The LOGIC-SENS intelligent signal processing feature can be activated or deactivated via the
diagnostic software. If the signal evaluation is switched on, LOGIC-SENS recognizes briefly
occurring disturbance variables and can thus prevent a deceptive alarm.

Setting the Fan Voltage

The standard setting fan voltage setting is 9 V. In critical applications, the fan voltage can be
set to a higher level via the diagnostic software. This increases the transport speed in the pipe
system, thus achieving faster detection in the case of longer pipe lengths.
With a fan voltage of 9 V to 10.4 V, the maximum pipe lengths are reduced to 30m for I-pipe
systems or 40 m for U and double U-pipe systems. A fan voltage of 10.5 V or higher supports
the maximum pipe length.

Caution!
Whenever the fan voltage is changed, the FCS-320-TM automatically performs an airflow

initialization.
5.5.11

Entering the current air pressure

The current air pressure in the monitoring range must be entered via the diagnostic software if
air-pressure-dependent calibration is required.
The default setting is 1013 hPa. This corresponds to the average air pressure at sea level.
5.5.12

Entering the height above sea level

The value of the height above sea level is that of the location where the FCS-320-TM is
installed. This value is entered via the diagnostic software. The standard deviation is 0 m. If
the airflow sensor in the unit requires air-pressure-dependent calibration, it is necessary to
change this value.
