Connecting Activators
Activators are external devices such as alarms and lights that can be turned on by the system in response to an
event. Essentially, the unit functions as an on/off switch for these devices. The unit activates an activator by closing
the circuit of its power supply. Two activators can be connected directly to the unit. In addition, if you wish, you
can connect an IA-3126-2 relay board to the unit. This makes it possible to connect up to 16 additional activators to
the unit (see Connecting Sensors and Activators Using an IA Relay Board, page 16).
In addition to the activators themselves, you will need the 16 AWG red and black cables to connect each activator
to the unit.

To connect an activator:
1. Install the activator in its desired location in accordance with the manufacturer's instructions.
2. Connect the two contacts of the activator to the Activators terminal block on the rear panel of the UVG400, as
illustrated in figure 11.
Note: The wires must be connected to two adjacent contacts in the same group (e.g. the two contacts of
“Out1”), but the polarity does not matter.

Connecting Sensors and Activators Using an IA Relay Board
If you want to connect additional dry sensors and/or two activators to the UVG400, 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 UVG400’s configuration utility.
NOTE: Alternatively, you can connect additional sensors using an ADAM module, as explained under
Connecting Sensors Using an ADAM Module, page 12. Sensors that are connected through an ADAM
module can be configured using the UVG400’s configuration utility.
