    How small are you talkiing?

    We use Leibert GXT-1000's. They have alarm relays available through a db-9 connector. In fact, I think the last two we put in have a USB port for communication.

    We just moved into a place with a natural fp which worked fine last month. Tried a fire yesterday with 30-mph winds and now the whole house reeks of woodsmoke. I'll have to look at the chimney when I...

    repairing RC1000, RC2000 boards

    Does anyone have a source for getting old ECI and Danfoss CPU boards repaired? The outfit we were using went out of business last fall, and Danfoss won't touch them any more.
