7.2.2 Testing the fire detection functionality
The table below shows the accessories with which the fire channel can be tested in
the various sensor modes.

If the point detector is working in test mode, the following must be noted:
In test mode, the point detector responds according to the sensor mode selected.
This means when the point detector is operated as a heat detector (sensor
mode 1), it must be thermally checked as well.
Selecting test mode on the fire control panel does not deactivate evaluation of the
functionality of the 'Technical CO Alarm' and 'Technical Ambient Supervision
Alarm'.
When the detector is in alarm condition, the internal alarm indicator flashes. For
information on the flashing modes, observe the notices in chapters 'Internal alarm
indicator in the case of ES <20 (OOH740 and OOHC740) [

7.2.3 Testing the CO functionality (only for OOHC740)
The table below shows the accessories with which the gas channel can be tested.

If the point detector OOHC740 is working 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.
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.
