Marc,
Boy - you gave me an idea of another item to check at my QTH - Always
tracking noise sources here by the Jersey shore.....
Who owns the hardware?
If they do not respond in a reasonable way, I would call into the
organization's President or VP and lay it on the line - If they turn a
deaf ear, you'll drop them like a hot potato - The alarm business has
many competitors that would love your business.
Let's hear what hardware/manufacturer you're dealing with model number
etc. Sounds like one to stay away from.
