FCS-320-TM Aspirating Smoke Detector
F.01U.130.928 | 1.0 | 2009.11
Operation Guide
Bosch Sicherheitssysteme GmbH
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.
6.6
Checking Airflow Monitoring
Pipe breakage
Check the breakage detection:
1.
Detach the pipe from the connection to the FCS-320-TM or open the test adapter.
2.
Check whether the malfunction display on the smoke aspiration system lights up.
3.
Alternatively, check the data of the airflow sensor using the diagnostic appliance and a
PC or laptop.
4.
Enter the result in the test log.
obstruction
Check the obstruction detection:
1.
Close – depending on the planned airflow monitoring – the corresponding number of air
sampling openings with some duct tape.
2.
Check whether the malfunction display on the aspirating smoke detector lights up.
3.
Alternatively, check the data of the airflow sensor using the diagnostic appliance and a
PC or laptop.
4.
Enter the result in the test log.
Troubleshooting
If the airflow malfunctions are not correctly detected by the unit, proceed as follows:
Check whether…
1.
All borings are free
2.
The pipe system has breaks or fractures
3.
All pipe connections are tight
4.
The fan can blow out freely
5.
The correct aspiration reducing film sheets were used
6.
Any test adapters and air filters are closed
7.
Any filter inserts are clean
8.
Any ball valves and blowing-out valves are in the operating position.
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
).
6.7
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.
NOTICE!
The steps below may only be carried out following an airflow calibration in accordance with
Section 6.3 Calibrating the Airflow Sensor
.
