3.1.2 Features of the 'Technical CO Alarm'

Alongside its fire detection functionality, the FDOOTC241 also has a CO detection

functionality with the following features:

Static or dynamic alarm profiles
Real time interpretation of the situation
Process- and time-controlled switchover of the parameter sets for CO

Signal processing by the 'Technical CO Alarm' is undertaken regardless of CO

signal processing for the fire detection functionality with the 'Suppression CO' and

'Balanced CO' parameter sets.
The signal processing feature of the 'Technical CO Alarm' enables optimum

calculation of the CO concentration. The electro-chemical cell allows the best

possible level of accuracy to be obtained depending on the ambient conditions.
The FDOOTC241's CO detection is characterized by the ability for parameters to

be set and a relatively low cross-sensitivity to other gases, e.g. ethanol or

hydrogen (H

2

).
