Re: Keyscan CA8000 Question

["petem" <petem001@xxxxxxxxx>]

I worked on some keyscan system and what you told us is definitely a
programming issue,
first thing that make me say that is,if you tie the led signal line to
another output it works ok,
so that mean the problem is not with wiring or with the reader

next thing is that the way it flash look like the programmer told the system
there was an input associated to the out door and as its lock for the after
hour schedule it doesn't see the closed zone and react as door open too long
or door forced state

now there is 1 easy way to fix that,put a resistor to the input programmed
for the out ready door,or program the same input in both reader as the door
status input........
