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.
