Draeger VarioGard Central Unit


The Dräger VarioGard Central Unit is at the center of a cost-efficient, modular gas detection system. A digital Bus makes it possible to connect and manage up to 100 transmitters for various gases.

Multifaceted Alarm Management

  Four concentration alarms and four average alarms can be programmed on a freely selectable time base for each connected transmitter. If a gas alarm is detected, visual, audible and electrical indicators are activated so that suitable action may be taken.

 

Configured to meet customer requirements

  “A VarioGard system can be individually put together and programmed, in accordance with customer specifications. VarioGard Transmitter, VarioGard Relay Module, VarioGard Converter Module and VarioGard Battery Module can be selected as modules. The three-wire digital bus cable for connecting the individual modules can be up to 1100m long.”

 

Simple operation

  “The device is configured using six keys and a two-line display. The equipment comprises a three-color LED [standard operation (green), warning (yellow) or alarm (red)], a built-in audible alarm, and five programmable relays. “
