Alarm Detection Systems (ADS) finalized the business acquisition of Illini Security Services of Sycamore, Ill. this week. The transaction welcomes hundreds of new alarm customers from the Western Chicago suburbs under the ADS name. 

Alarm Detection Systems wants to make sure Aurora police officers have tools that can help protect them if an incident occurs like the one they faced on Feb. 15, 2019, at the Henry Pratt Company at 401 S. Highland Ave. on Aurora’s West side.
