The CO signal helps to speed up alarm activation in the event of smoldering fires but cannot
1
trigger fire alarms on its own.
Only for OOHC740: If the 'Suppression (5)' parameter set is needed, 'Suppression CO (12)' should
2
be used for new applications.
Depends on CO proportion.
3
In the case of open fires, the proportion of CO in the fire gas make-up is low. With high proportions
4
of CO, the sensitivity could theoretically increase by up to 0.9 %/m with open fires (i.e. instead of
2.3 %/m to 1.4...2.3 %/m, for example).
Only in the OOH740 from ES ≥20
5
The static activation temperature of 80 °C is above the operating temperature
range permissible for continuous periods.
The point detector may only be used in continuous operation within the specified
temperatures!
