Results
The following modules can be used with the relevant settings for class B or A:
– 0.015% LT/m (0.05% LT/m) module – with a sensitivity of min. 0.12% LT/m (0.4% LT/m)
– 0.1% LT/m (0.25% LT/m) module – with a sensitivity of min. 0.2% LT/m (0.5% LT/m)
– 0.5% LT/m (0.8% LT/m) module – with setting 0.5% LT/m (0.8% LT/m)
System parameters possible:
– I-pipe system
9V fan voltage, max. 80m total pipe length for U-pipe system
– U-pipe system
6.9V fan voltage, max. 110m total pipe length
9V fan voltage, max. 110m total pipe length
– M-pipe system
6.9V fan voltage, max. 110m total pipe length
9V fan voltage, max. 160m total pipe length
– Double U-pipe system
6.9V fan voltage, max. 140m total pipe length
9V fan voltage, max. 160m total pipe length
Notice!
The sensitivity value is based on measurements with standard test fires (old value in
brackets).
