Les, here is the UL listing for the FBI XlCPRO system panel I have in my house.
FBI was purchased by Honeywell and renamed Omni series. I think the XLC is now the OMNI848 if I am not mistaken. I found installing and monitoring alarm systems to be quite lucrative for eventual selloff of the accounts to a national chain, but the day to day dealings with that business is not my particular cup of tea.
