Is it necessary to have a LV warning module when using an EFIS?  Many (eg

stratomastor Enigma) have alarm and warning functions that will warn of a

low voltage occurrence.



Ref Z16 in Aeroelectric connection.

If you are unhappy with the consequences of a total electrical  

failure, then you should ensure that you have active notification of  

an alternator failure.  A low voltage warning, with a very noticeable  

warning, is a good way to do that, as a low system voltage is a good  

indication of an alternator failure.   It really doesn't matter  

whether the low voltage warning is provided by a separate low voltage  

warning system, or whether it is provided by some other system  

(engine monitor, EFIS, etc), as long as it is effective.



If you are convinced that the low voltage warning provided by the  

EFIS will be quickly noticeable, then it should be all you need.

Thanks for the question and the answer. I will put low voltage on my checklist when I install my electrical system.  I am just getting started and gleaming every morsel of info I from the list.



Have a good one.

   You only need one LV warning system. You choose.
