Dave;
Not necessarily. It depends on where you place the wiring and small backup
battery. Think of a fire suppression system as a critical system on a
fighter that must survive battle damage-- redundency and routing systems
through less- vulnerable areas certainly helps. The routing of hydraulic
(brake) lines, chute release lines and critical electrical wiring, etc. all
need to be carefully thought out with an eye toward where a fire is most
likely to occur and where it will do the most damage at speed. Things like
fire sleeves can help lines survive for a bit longer than if they are bare.
When all is said & done, I agree with you-- I'd still like to have the
option of a manually- operated mechanical linkage to actuate my fire-
suppression system but it would be in addition to the automatic system. As
they say, "Simplicity is Golden; complexity for it's own sake is a pain..."

Wouldn't common sense tell you that if there is a fire than you have to
assume
the electric stuff is all dead???
I would have to also believe that a mechanical linkage or actuator would be
mandatory for the same reason or if not at least for personal safety...
