The LSNimproved version allows T-taps on stubs or loops and any number of nodes, branches
per node and elements per branch as long as the maximum number of elements does not
exceed 254.
Connections can be positioned anywhere along the LSN line.
Notice!
Planning should take the anticipated total current and line resistance into account to ensure
each detector has an operating voltage of at least 15VDC.
As soon as an LSN classic device is in a loop or stub, only loop or stub structures can be
used. In this case, T-tapping is no longer possible.
