HVG400 Installation Guide

Connecting Devices to the HVG400

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 15).

In addition to the activators themselves, you will need 16 AWG red and black cables to connect each activator to

the unit.

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 HVG400, 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 HVG400, 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 PVN SerVision client applications and activators can be turned on and off via these

applications. However, the sensors and activators cannot be configured using the HVG400’s configuration utility.

NOTE: Alternatively, you can connect additional sensors using an ADAM module, as explained under

Connecting Sensors Using an ADAM Module, page 11. Sensors that are connected through an ADAM

module can be configured using the HVG400’s configuration utility.
