Testing air flow monitoring
WARNING
The following steps can only be taken after air flow adjustment as de-
scribed in Chapter "Air Flow Sensor Adjustment" has been carried out.
Test that a pipe breaks will be recognised:
1. Loosen the pipe at the connection to the TITANUS
MICRO·SENS
®
or
open the test adapter.
2. Check whether the fault display on the aspirating smoke detector is
flashing.
3. Check the air flow sensor data using the DIAG3 diagnostics tool and a
PC or laptop.
4. Enter the result in the test record.
Test that a blockage will be recognised:
1. Depending on the air flow monitoring arrangement designed in, close the
corresponding number of aspiration apertures with some sticky tape.
2. Check whether the fault display on the aspirating smoke detector is
flashing.
3. Check the air flow sensor data using the DIAG3 diagnostics tool and a
PC or laptop.
4. Enter the result in the test record.
If air flow faults are not correctly recognised by the device, proceed as fol-
lows:
Check whether ...
1. All holes are free.
2. The pipe system has any breaks or cracks.
3. All pipe connections are sealed.
4. The fan can blow freely.
5. The correct aspiration reducing films have been used.
If a defect is found, the functioning of the TITANUS
MICRO·SENS
® or the
air flow sensor will be tested using a test pipe or the diagnosis software (see
section "Testing the air flow sensory analysis function").
