Checking Airflow Monitoring; Functional Test Of Airflow Sensors - Bosch FCS-320-TM Operation Manual

80 en | Commissioning
Malfunction transmission occurs as part of checking the airflow monitoring system (as per
section below).
Check whether, when a pipe breakage and an obstruction are detected, the malfunction is
displayed at the aspirating smoke detector and at the fire panel.

Checking Airflow Monitoring

NOTICE!
The steps below may only be carried out following an airflow calibration in accordance with
Section 6.3 Calibrating the Airflow Sensor.
Pipe breakage
Check the breakage detection:
1.
2.
3.
4.
obstruction
Check the obstruction detection:
1.
2.

Troubleshooting
If the airflow malfunctions are not correctly detected by the unit, proceed as follows:
Check whether...

2.
3.
4.
5.
6.
7.
8.
If no faults are detected, the operativeness of the FCS-320-TM and/or the airflow sensor is
checked by means of the test pipe or diagnostic software (see Section 6.7 Functional Test of
Airflow Sensors, Page 80).

Functional Test of Airflow Sensors

Check the operativeness using a test pipe and a digital precision pressure gauge and with the
aid of a PC and the FAS-ASD-DIAG Diagnostic Software.
A full functional test using the digital precision pressure gauge is described below. A limited
functional test can also be carried out without a digital precision pressure gauge.

Detach the pipe from the connection to the FCS-320-TM or open the test adapter.
Check whether the malfunction display on the smoke aspiration system lights up.
Alternatively, check the data of the airflow sensor using the diagnostic appliance and a
PC or laptop.
Enter the result in the test log.
Close – depending on the planned airflow monitoring – the corresponding number of air
sampling openings with some duct tape.
Check whether the malfunction display on the aspirating smoke detector lights up.
Alternatively, check the data of the airflow sensor using the diagnostic appliance and a
PC or laptop.
Enter the result in the test log.
