System Enhancement Module and Gateway For Honeywell Vista Series

The new ADC-SEM-100-CDMA is a system enhancement module designed by Alarm.com to be used on Honeywell Vista 10P, Vista 15P and Vista 20P security systems. The main function of the SEM is to let your Honeywell Vista system send alarm signals to a central station monitoring service using Alarm.com's signal forwarding plan. The signals are sent on the CDMA cellular network insuring fast, reliable communications.

You can also, with your SEM, take advantage of Alarm.com's residential or commercial remote services. This SEM also features a Zwave control module that can be used with Alarm.com's Residential Advanced Interactive or Residential Interactive Gold packages which give you full remote control of your Zwave home automation devices. This will allow you the same control if you have Alarm.com's Commercial Services as well.

The SEM does not require its own power supply as it draws power from the panel's auxiliary power and battery. By utilizing the panel's power and backup; the SEM can perform reliably for up to 24 hours during a power outage. If you have Alarm.com's residential or commercial remote services packages you will be able to view system and sensor status/history, remotely arm and disarm the system, set up and manage user codes, and create customized e-mail and text message notifications for any type of alarm or non-alarm activity at the property where this is installed. Also, if you have the proper service package, like Residential Gold, you will be able to manage and control your home's Zwave devices because of the SEM's built-in controller. Set up scenes and trigger events to make your home smarter and more energy efficient.

You can get Alarm.com's great service features on your Vista system by using the SEM module. You will be able to arm/disarm the system remotely, see zone/device status and history, you will also be able to set up and manage user codes as well as setting up custom email and text messages to alert you of any violation of your system. You can also take advantage of Alarm.com's home automation features as well. If you have Zwave devices in your home; the SEM will allow you to control and set scenes through your Alarm.com account.

With the SEM's easy-to-read status LEDs you'll always be able to determine if there is an error condition with the unit and easily troubleshoot. You will also receive OTA (over the air) upgrades that will be automatically pushed to your SEM to keep it as relevant and current as possible. All of these things are why Alarm.com is becoming our favorite service to use.
