7.3.2 Testing the functionality of the 'Technical CO Alarm'
The following table shows the accessories with which the FDOOTC241 can be
tested in sensor mode 0.

Sensor mode 0 (Technical CO Alarm) X – X –
If detector FDOOTC241 is in test mode, the following must be noted:
Because the fire detection functionality is not automatically deactivated during test
mode for CO, the documentation provided for the control panel must be consulted
for details of how to proceed (for FS20 control panels as of MP2.1).
Deactivating the 'Technical CO Alarm' on the fire control panel does not
deactivate the fire detection functionality and the 'Technical Ambient Supervision
Alarm'.
If you are using CO test gases which haven't been approved, a fire alarm may be
activated during testing if additional setting of test mode is not undertaken on the
fire control panel.
If the detector is in alarm status, the internal alarm indicator flashes brightly every
second.
7.3.3 Testing the functionality of the 'Technical Ambient Supervision
Alarm'
You do not have to check the functionality of the 'Technical Ambient Supervision
Alarm' on a regular basis.
Testing the fire detection functionality and the Technical CO Alarm ensures that the
'Technical Ambient Supervision Alarm' also works.
