Aspirating Smoke Detector
Notice!
The sensitivity value is based on measurements with standard test fires (old value in
brackets).
The activation threshold for the airflow malfunction is set to 20% volume flow change by
default. Higher values are not permitted within EN 54‑20 or ISO 7240-20 .

Connecting an External Detector Alarm Display
A digital external detector alarm display can be connected to the FCS-320 series aspirating
smoke detectors. This is available by separate order.
Connect the remote indicator to the motherboard of the FCS-320 using the terminal strip X6.
The unit must be in a voltage-free state for this.

Data Logging
Connecting a PC via the diagnostics cable
The FAS‑ASD‑DIAG Diagnostic Software is used to conduct the device tests.
The current airflow sensor data, smoke level values, various status values and the parameters
configured via the programming software can be read out locally using a laptop. This makes it
much easier to detect altered operation conditions in the event of service being carried out.
The supplied diagnostics cable connects the aspirating smoke detector ("DIAG" connection on
the motherboard) to the PC. The FAS‑ASD‑DIAG version is connected to the PC via a USB port,
earlier DIAG versions use a COM.
For details, please see the diagnostic software documentation.
