RE: LED Door Lock Status Indicator Hack

["Jim \(List\)" <jim.list@xxxxxxxxxxxxxxxxx>]

I've always taken that red=3Ddanger, green=3DOK.

So, applying that to the purpose of the door status, red=3Dunlocked
(danger=
of
unauthorised entry).

If the purpose was to warn that the door was locked (i.e. on a card-entry
system), then red=3Dlocked, green=3DOK to open.

Nice write-up Martin - I wish I'd run cable to door & window frames
too.

I wonder what others' views are on the red/green colour code. I appreciate
it can be a personal thing but my instinct would've been red=3Dlocked,
green=3Dopen rather than the other way around.

Cheers,

Tim.
