Connecting Devices to the MVG400 22

3. Connect the activator to an external power supply, such as the vehicle battery.
Note: You may be able to supply power to the activator by connecting it to the 12VDC Power Out connector
on the rear panel of the unit (see Using the 12VDC Power Out Connector , page 38).
Connecting Sensors and Activators Using an IA Relay Board
If you want to connect additional dry sensors and/or activators to the MVG400, you can do so by connecting an
Intelligent Appliance IA 3126-2 relay board to the unit. Up to 16 additional dry sensors and 16 additional activators
can then be connected to the unit through the relay board. Sensor and activator events from devices connected to an
IA relay board can be seen in SerVision client applications and activators can be turned on and off via these
applications. However, the sensors and activators cannot be configured using the MVG400’s configuration utility.
NOTE:
Alternatively, you can connect additional sensors using an ADAM module, as explained under
Connecting Sensors Using an ADAM Module , page 18. Sensors that are connected through an ADAM
module can be configured using the MVG400’s configuration utility.
