Keyscan CA8000 Question

["Andrew Buchanan" <drewber@xxxxxxxxxxxx>]

Hey,

I've just finishing installing a brand new Keyscan System in a commercial
building.  I have two CA8000's and one CA4000  communicating via cpb10
boards to System 5 software via a network w/ a netcom unit.  There are both
reader/rex doors and some reader in/reader out doors, and all have contacts.
All the readers are HID slimline readers.  I am the sub contractor, so all I
installed was the hardware.  The software was set up by the main security
provider.  I can only assume that this question has nothing to do with the
software as everything else works perfectly.  However, there is a queer
little problem that is bugging me.

 I have a front door reader in/reader out which during normal business
hours,  the mag is unlocked.  Both led's on the two readers are green (This
may be different than what you may do but we set readers up to show red for
locked and green for unlocked).  At the panel I see that relay 1 is on,
which it should be, as I tied everything hardware wise to the in reader, and
both readers one & two fire relay output 1.  Straight ahead of this door is
another reader in/reader out door which during normal business hours is
locked.  Both readers show a red led and when a valid card is swiped on
either  reader, both go green to show unlocked, and the mag is released as
it should even though hardware wise they are not tied together at all.

After hours, the front door locks via its schedule and works exactly the way
it should with a valid card read.  The inner door opens (the business is
almost 24hrs so the customer wants no one except employees to come in.) via
its schedule and works almost they way it should.  The in reader, which has
the contact tied to it properly, shows green and the associated lock relay
opens dropping the mag.  The out reader, goes green.....then flashes
red/green/red/green/red/green for a second or two, goes green and then
repeats the cycle.  There is no reason for this reader to be flashing at
all.  It is causing quite the confusion with the employees as they are
unsure if the need to swipe or not.  I checked the wiring.  All seems ok.  I
jumpered out its contact point.  No change.  And like I said above there are
4 other scheduled reader in/reader out doors which are not hardware
connected which work perfect, both in there locked state and in there
unlocked state.  So I do not believe that it is software, as I know the
person who programmed the system, and he is usually very good at it.  In
order to stop the flashing led I needed to tie in the out led to follow what
the in led does.  So with a piece of jumper wire I've solved a problem which
should not have been there in the first place.

My question is what could be causing this problem?  Its really starting to
bug me as I think I should either have to always tie the leds together
physically or not at all.  Have I overlooked a obvious thing?  This could be
just a little system glitch that does happen from panel to panel, giving
grief to installers who want it all to work the first time.

Oh well, any suggestions would be great.
