The Alarm.com System Enhancement Module (SEM 300) turns a legacy security alarm panel such as the Honeywell Vista or DSC PowerSeries into a modern Alarm.com-compatible security system with remote control via the Alarm.com app, home automation via Z-Wave, and dual-path communication (both cellular and internet).
Installing a SEM300 requires electronics wiring and legacy alarm panel keypad programming that can be daunting for some. It’s a technically advanced installation. Only attempt it yourself if you’re comfortable with this.
