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

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.
Selecting the test mode for 'Technical CO Alarm' on the fire control panel does
not deactivate the fire detection functionality and the 'Technical Ambient
Supervision Message'.
If using CO test gases which haven't been approved, a fire alarm may be
triggered during testing if additional setting of test mode is not undertaken on the
fire control panel.
When the detector is in alarm condition, the internal alarm indicator flashes
brightly every second.
7.3.3 Testing the functionality of the 'Technical Ambient
Supervision Message'
You do not have to check the functionality of the 'Technical Ambient Supervision
Message' on a regular basis.
Testing the fire detection functionality and the 'Technical CO Alarm' ensures that
the 'Technical Ambient Supervision Message' also works.

7.3.3.1 'Technical Ambient Supervision Message' performance
check
You cannot test whether the 'Technical Ambient Supervision Message' is
functioning correctly with test devices.
Checking can only take place indirectly:
You must know the current ambient temperature.
Enter the following parameters in the 'SintesoWorks' software:
– A hysteresis range of 5 °C.
– A temperature threshold which is at least 10 °C below the current ambient
temperature.
– Alarming when value falls below threshold
The detector sends a signal to the control panel.
The 'Technical Ambient Supervision Message' is working correctly if the control
panel displays the corresponding message.
