Can I order a Verbatim to pass a UL inspection on my panel?
Yes. You select the desired Verbatim configuration and add the external UL approved power supply option. This removes all 120 VAC from the unit and supplies it with 12 VDC, which is accepted by all 508 UL inspectors. Also, the phone line input is protected per UL 1459/1950 requirement for high power. UL does not have a standard for a process alarm autodialer.
