For an alarm system I require that it be certified by Underwriters Laboratories:

We had to get some computerized equipment "UL Approved" and, since it was all low voltage except the power supply, all we needed to do is make sure nobody could touch a high voltage contact and use a UL Approved power cord. I expect that your UL Approved alarm just has an Approved power brick like most every laptop. They are not certifying the quality of the alarm system.
