5.7 SelfVerify® 2.0 Function
As an add-on feature, Autronica provides the SelfVerify® 2.0 system
function. The function is performed automatically every 24 hours,
and is a calibrated self-test of the sensor elements verifying that the
sensitivity of the protector is within the approved range. In addition
to the daily system test, SelfVerify® 2.0 includes 100 % of the signal
path, and 99 % of all components in the protector, and it is run
internally every other second, giving an immediate warning if a
discrepancy is detected. The advanced SelfVerify® 2.0 function
removes the need of manual testing and inspection.
If the protector has integrated FAD (Sounder or VAD), the SelfVerify®
2.0 test will be performed on these functions as well, ensuring that
the sounder/loudspeaker element is able to produce sound and the
LED is able to produce light.
A clicking sound occurs while the SelfVerify® 2.0 test of
sounder/loudspeaker is being performed. A short light blink will
occur during a SelfVerify® 2.0 test of the VAD.
For more information about SelfVerify® 2.0, refer to “Testing and
Maintenance”, chapter 11.1.
Note that manual inspections may be required according to local
regulations.
5.8 Cover Detection
As an add-on feature, Autronica provides “Cover Detection”. The
AutroGuard® protector’s top cover has an exposed surface. The
Cover Detection functionality will detect if the protector is covered in
such a way that smoke is prevented from entering into the detection
chamber. A fault message will appear on the system panel after 5
minutes. Short term covering (<30s) will not be reported as a fault,
but will increase the sensitivity of the protector and will start flashing
the LEDs.
Cover Detection is easy to enable or disable by configuration.
The following settings apply to Cover Detection Sensitivity:
Off (will never give a fault message)
Normal (
detects all materials that can be unequivocally identified
as blocking the air inlet
)
High (detects more challenging materials that might not always
completely block the air inlet). Challenging materials may be, for
example, a transparent plastic bag, a thin and transparent black
clothing/fabric (for example, a thin black sock)
For further details, refer to Configuration, chapter 10.6.3.
