RE: LED Door Lock Status Indicator Hack



HID Prox access systems (one of the biggest in the world)

RED =3D Locked
Green =3D Unlocked
=20=09=20
But on a personal basis I agree with the concept of Red =3D danger

If SWMBO and kids don=92t have regular use of access systems never any
reas=
on
to confuse them..

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.
