Application-specific parameter sets
15
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
Only for OOHC740: If the 'Suppression (5)' parameter set is needed, 'Suppression CO (12)' should
be used for new applications.
3
Depends on CO proportion.
4
In the case of open fires, the proportion of CO in the fire gas make-up is low. With high proportions
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).
5
Only in the OOH740 from ES
≥
20
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!
