Tracy,

I didn’t initially hook up the alarm light on my system as = I was concerned that it would be going off all the time while I got everything working. Well today I hooked it up. I wired P3-10 to the = positive on a 5V LED and P3-2 to the negative side. When I turned the EM-2 = on, the light did not light.

Is this expected behavior? I thought the alarm would go = off if anything was out of its setting. The voltage was low so at least something was out. (I am not concerned about this as I have a low = voltage monitor which was telling me at the time that I had low = voltage.)

Thanks,
