Line calculation The maximum line length results from the permitted line drop on the feed.
The permitted line drop is the difference resulting from the stand-by ac-
cus discharge voltage (21.5 V) and the lower operating voltage limit of
the aspiration smoke detection system.

To guarantee the tightness of the housing seal, the appropriate cable
throughput for the particular cable must be selected.
z M 25- cable throughput: ∅ 9 to 14 mm
z M 20- cable throughput: ∅ 8 to 12 mm
