com. Pick up any electronic device and you might notice a little “UL” logo on the bottom. That’s short for Underwriters Laboratories, an independent agency
that tests electronics to make sure they’re not just pieces
of junk. The UL also tests home security monitoring stations. Its testing methods cover a lot of the same ground as the FM Approval, but it goes even further, reviewing the quality of the monitoring technology and the knowledge, response times, and abilities of the operators and employees. If a station gets the UL stamp of approval, its operators, technology, and facilities are the best of their class.
