What does that mean anyway?
Underwriters Laboratories Inc. (UL) is an independent, not-for-profit product safety testing and certification organization, and is one of the most recognized, reputable conformity assessment providers in the world. UL qualifies alarm service companies for Listing and for Certificate service by reviewing examples of their work. After the alarm company becomes "Listed," it's the company's declaration that its systems will be installed, maintained, tested and monitored in accordance with the highest codes and standards. UL Standards for Safety are essential to helping ensure public safety, reduce costs, and improve quality.

Unlike Protection Networks, most alarm companies don't have the seal of approval from Underwriters Laboratories. For more information visit www.ul.com.
