Acquisition Module or an IA-3126-2 relay board to the unit. Either of these devices makes it possible to connect up
to 16 additional sensors to the unit.
Sensor 1 and Sensor 6 can be used as switches instead of sensors. The switches can be used to activate outlines and
to change the display on a CCTV monitor.
Connecting a Sensor Directly to the Unit
The unit has six sensor connectors (In1 – In6). You can use these connectors to connect up to six dry-contact input
sensors directly to the unit. Alternatively, In1 and In6 can be used to connect switches as follows:
 In1: If you are defining more than one outline (alternate sets of recording and event-handling settings), you
can connect a toggle (on-off) switch to In1 instead of a sensor. The switch can then be used to change the
active outline. For additional information, please refer to the Embedded Video Gateway System Guide.
Note: Some alarm panels can also be connected to In1. When they are, they can function as automatic outline
toggle switches. For additional information, please consult the alarm panel vendor.
 In6: If a CCTV monitor will be connected to the unit, you can connect a push-button switch to In6 instead of
a sensor. The button can then be used to change the display on the monitor. For additional information, see
Connecting a CCTV Monitor, page 18 and refer to the Embedded Video Gateway System Guide.

To connect a sensor or switch directly to the unit:
1. Install the sensor or switch in its desired location in accordance with the manufacturer's instructions.
2. Connect the two wire contacts of the sensor or switch to the Sensors terminal block on the rear panel of the
HVG400, as illustrated in figure 5. Insert the wires into the connectors and tighten the screws below each
connector to hold the wires in place.
Note: The wires must be connected to two adjacent contacts in the same group (e.g. the two contacts of
“In1”), but the polarity does not matter.

Connecting Sensors Using an ADAM Module
If you want to connect additional dry sensors to the HVG400, you can do so by connecting an ADAM Data
Acquisition Module to the unit. Up to 16 additional dry sensors can then be connected to the unit through the
ADAM module.
NOTE: Alternatively, you can connect additional sensors using an IA-3126-2 relay board, as explained
Connecting Sensors and Activators Using an IA Relay Board, page 15.
To connect sensors using an ADAM module, you will need the following items:
 ADAM-4051 Data Acquisition Module (available from SerVision)
 ADAM-4520 isolated RS232->RS422/RS485 converter (available from SerVision)
