[Hai-users] Problem with ALC lighting on OmniPro II

[James Rupert]

You bring up a good point. Recessed light housings have a thermal over load
shut off device in them. If the cans have to big or the wrong type of bulb
or if there is insulation around a can that isn't rated for zero clearance
they will over heat and shut themselves off. Could the problem be with the
lights and not the switches?

I have about 50 alc light switches and dimmers on an omnipro2.  There is one
circuit, and only one, that exhibits the annoying behavior that you
describe....but only in that they turn off randomly...my dining room ceiling
can lights.  This has happened regularly for the last 5 years.

I have always assumed that the problem was heat related...I have seen the
same behavior in a non-controlled situation in a different house.  I have
never followed up with any troubleshooting, but I would love to hear what
you find out.

Other than this one troublesome circuit, ALC has worked flawlessly for me.
No delays, no odd behavior, just solid performance.  Hope you work this out.

Subject: [Hai-users] Problem with ALC lighting on OmniPro II

I recently added some ALC lights (wired via cat-5 to an OmniPro II), and am
experiencing some odd lighting behavior.  The lights will periodically
spontaneously turn on or off (primarily off).  This happens when no other
activity is occurring in the OmniPro II (e.g. no one is turning lights on or
off, and no timed events are triggering), and is random and unpredictable.
It typically is the case of a light turning off some minutes or hours after
manually turning it on.  It occurs with different lights in the house, so
doesn't seem to be tied to one switch.

I am going to start trouble shooting this by disconnecting different
switches from the OmniPro II to see if some switch is injecting commands
into the system in some way, although with the infrequent intermittent
nature of the problem, it'll be a long slow process of elimination.  I have
tried to eliminate all programming that references lights, to try to take
some kind of programming error out of the equation.  However, has anyone
ever encountered this kind of behavior before?  Could bad connections to the
switches cause this?  Is cat-5 sufficient for ALC signalling, or is it
possibile I am picking up some interference?

I have definately seen this kind of behavior from X-10 switches, and kind of
expect it there, but was surprised to see it in an ALC system.  I had hoped
it would be more reliable!  I have a bunch more switches to install, but am
holding up because of this problem.
