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.
Detection module
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.
Main alarm following Fire source identification
For certain applications, it is practical to perform the alarm signaling once the fire location has
been identified. To do this, the Fire alarm after ROOM·IDENT must be activated. It is important
to remember that when this function is activated, the ROOM·IDENT function must also be
activated; otherwise, the fire location cannot be identified.
The Main alarm after ROOM IDENT function is deactivated as standard.

Notice!
When inserting the detection module, be aware of the mechanical coding, which protects the
device against twisting.
