Application-specific parameter sets
1
The CO signal helps to speed up alarm activation in the event of smoldering fires but
cannot trigger fire alarms on its own.
2
Note chapter '4.1.3.1 Description', 'High Suppression (8)' paragraph.
3
Only implemented for reasons of compatibility. If the 'Suppression (5)' parameter set is
needed, 'Suppression CO (12)' should be used for new applications.
4
Depends on CO proportion.
5
In the case of open fires, the proportion of CO in the fire gas make-up is low. With
higher proportions of CO, the sensitivity could theoretically increase to up to 0.5 %/m
(i.e. e.g. instead of 2.3 %/m to 1.8 … 2.3 %/m) with open fires.
The static activation temperature of 80 °C is higher than the permanently
approved operating temperature range of the electro-chemical cells used for CO
detection.
The detector may only be used in continuous operation within the specified
temperatures!
All parameter sets except for 8 comply with standards EN 54-7 and CEA 4021.
