The switch can then be used to change the active outline. For additional information, see

Outlines, page 124; Sensor and Activator Settings, page 115.

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.

• In4: If a CCTV monitor will be connected to the unit, you can connect a push-button

switch to In4 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 24;

Configuring a CCTV Monitor (TV-Out), page 54; Sensor and Activator Settings,

page 115.

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.

Note: If the sensor requires an external power supply, you may be able to connect it to

the 12 VDC connector on the rear panel of the unit. However, bear in mind that the unit

can supply a maximum of 500 mA of power. If the devices connected to the unit require

more than this amount of power, you must power some or all of them independently.

2. Connect the two wire contacts of the sensor or switch to the Sensors terminal block on

the rear panel of the MVG 400, as illustrated in figure 7. 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 more than four dry sensors to the MVG 400, 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.

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)
