Test mode
For testing purposes the point detector OOH740-A9-Ex can be set to test mode. In
test mode the point detector reacts faster and with a higher sensitivity level.
Physical testing:
The optical function part can be tested with the test gas REF8 or REF8-S.
l
The heat sensors can be tested with the following tools:
l
–
Hot air fan
–
Detector tester RE7T
Behavior in degraded mode
For the C-NET and a C-NET connected to the , the following applies:
When the main processor of the fire control panel fails, the control panel is in
degraded mode operation. Depending on the control panel type, the fire control
panel can continue to perform the most important alarming and signaling functions
in degraded mode operation.
Behavior of control panels that support degraded mode operation:
Alarming is still ensured in degraded mode operation. However, in degraded mode
only collective alarming is possible. This means that in the event of an alarm, it is
possible to identify the C-NET detector line but not the exact location of the
detector triggering the alarm.
Degraded mode operation on the C-NET is not supported in the same way by all
control panels. The information in the 'List of compatibility' and in the corresponding
control panel documentation must be taken into account during project planning.
Line tester
WARNING
Using the line tester FDUL221 during commissioning
Risk of explosion
●
Only operate the line tester FDUL221 in the area that is not at risk of
explosion.
●
If peripheral devices on an C-NET-Ex detector line are to be read into the line
tester FDUL221, make sure there is a line adapter (Ex) FDCL221-Ex between
the line tester and the peripheral devices.
The line tester FDUL221 is able to recognize and localize the following errors on
the C-NET-Ex:
Wiring error
l
Open line
l
Short-circuit
l
In addition, the line tester recognizes the devices connected to the C-NET-Ex
detector line.
