Calibrating the Airflow Sensor
The airflow sensor calibration of the FCS-320-TM Aspirating Smoke Detector is performed
automatically when the detection unit is inserted into the housing base, provided that the X4
jumper has been plugged into another socket first. This plug-and-play feature makes the FCS-
320-TM considerably easier to commission. In addition, the calibration can also be performed
using the FAS-ASD-DIAG Diagnostic Software. The initialization phase is therefore carried out
according to or independently of the air pressure as desired.
Pipe System
A pipe system with an overall length of up to 50 m can be connected to FCS-320-TM series
Aspirating Smoke Detectors over a maximum of 8 aspiration points. A maximum of 5
aspiration points can be connected with ROOM·IDENT.
