VOICE agent Description

The VOICE agent remote alarming module is a compact device designed for DIN rail mounting with a 110-230VAC or 24VDC power supply.
The VOICE agent is equipped with 16 iputs for 24VDC. Up to eight of the inputs can be configured as analogue inputs.
Against this are four digital relay outputs (e.g. collective- or hornoutput). The outputs can be altered by SMS.
All operating states, the time, analogue values and communication activities are shown in the display.
Of course, the VOICE agent is also a solution to expand an existing system.
Voice messages are transmitted using Voice over IP or the LTE network.
The connection paths can be monitored. In the event of a failure, an alarm can be sent either via the second voice channel or by e-mail.
A test message can be sent at periodic intervals to test device operation. If this message is sent by e-mail it includes the acutal values including the analogues.
Calling the device provides the information if there are actually any alarms.

All events are recorded in a log memory. This can be used to find out when an alarm arose and which subscriber acknowledged it.

To ensure proper function during power blackout, the VOICE agent has an integrated battery charge controller for an external connected battery pack. The battery conditon is monitored.

The actual status of the in- and outputs is visualised in the browser. Additionally, the value of analogue inputs is shown.

A web browser is used for programming the system. This means that no software needs to be installed or updated. The VOICE agent can be programmed and maintained over the network or the telephone line. Remote programming and maintenance is possible ober the network or LTE. The optional text to speech engine generates all spoken messages automatically. This comfortable function features the following languages: German, French, English and Italian. Please order the language you need together with your VOICE agent

You can expand the VOICE agent to a complete monitoring system:

VOICE VOICE agent extension

The use of the VOICE agent extension enables the upgrade of the monitoring- and controlling system up to 64 inputs and 52 outputs. Every extension module offers additional 16 in- and 16 outputs. A total of three extensions can be integrated over the network to the VOICE agent.

VA-D133 VOICE agent Operator module

The display and operator module displays the alarms in plain text, additionally the integrated sounder is activated. The 13.3" touch display offers the possibility to view the alarm list and current analogue readings as well as to review log files.


The VOICE agent offers a variety of communication options:


Local Remote
Display on VOICE agent in plaintext
Activate lamp/horn outputs on the VOICE agent and the extension modules
Network printer
Unix syslog messages on existing PCs
Alarm and status overview page in the web browser on existing PC's
Textual messages on PBX integratd desk phones using the ATAS protocol
Voice messages using VoIP
Voice messages using LTE
Messages to pager
Textual messages on PBX integrated DECT phones using the ATAS protocol
Notification of control centres / operations centres SIA DC-09 CID


Since all the programming takes place fully in the browser, there is no need to purchase software and updates. The configuration comes with graphics and is menu-based. For alerting, 30 stand-by groups with a total of 50 participants are available. For the voice messages, either the optional text-to-speech engine can be used or voice files can be recorded. A separate voice file can be stored for each of the 16 digital inputs. When used as an analogue input, 3 voice messages with different switching thresholds are available for each input. The fault message sequence is in accordance with DIN 19235. Delay times can be programmed for the inputs, the alarm triggering as well as for the jump to the next participant in the alarm chain. Each participant in the alarm list can acknowledge the fault by entering a code (DTMF tones) and thus stop further processing of the list.

Example of the programming by browser: Analogue input
