APX Mobile Radio Siren And Lights Interface Module


Emergency vehicles are a complex environment. Loaded with specialized equipment and controls, it's not easy to know where to look. An overloaded cockpit can lead to user distraction in critical moments. Motorola Solutions has collaborated with Futurecom Systems Group, ULC to deliver the Siren and Lights Interface Module (SLIM).

The SLIM creates a single touch point to operate all mission-critical equipment in an emergency vehicle. It enables APX™ control heads to operate light bars and sirens while also delivering a common microphone for PA and radio communications. Now you have a cleaner, simpler workplace that provides a safer and more efficient emergency vehicle experience.

Simple and compact, the SLIM module is installed in the trunk of the vehicle, where it interconnects the APX mobile radio with products from most of the leading lights and sirens manufacturers.
