The Drager REGARD 3000 control system is a modular gas detection system that can detect various gases and vapours. Its multi-coloured status light indicates the status of the system. You can combine three modules – Input, Relay and Gateway – and connect up to four analogue transmitters and eight relays with the controller.

Especially well visible and audible from a distance

​In the event of an alarm, every second counts – but it is also helpful to see the status of the gas detection system at a glance. The REGARD 3000 makes this possible with its status light. Different colours indicate whether everything is in order (blue), whether there are malfunctions (yellow) or whether alarms are pending (red). In addition, it can be seen immediately whether the alarm is active (flashing red) or has been acknowledged (continuous red light). This way, everyone on site is informed about the system status and daily checks are made easier.

Access the gas warning system more centrally

​Gas transmitters are often installed in areas that are difficult to access or far away from each other and the associated control unit. The REGARD 3000’s 4 – 20 mA HART® input module gives you central access to all diagnostic information in case of an alarm or fault. The transmitter configurations can also be read out and transferred conveniently. The intuitive touch display gives you an overview of the status of your gas detection system at all times.

Flexible options for expansion

​If the range of functions or the size of the gas detection system changes, The REGARD 3000 can be expanded by an additional relay or gateway module, depending on the requirements. This way, the system remains flexible and grows with the plant without shutting down the production process for longer. A REGARD 3000 can be equipped with a maximum of one input module, one relay module and one gateway module.

Networking individual systems with each other

​Do you have several gas detection systems with REGARD 3000 and REGARD 7000? Would you like to have all systems in view and control and configure them centrally? Then, connect the REGARD 7000 as a client to the REGARD 3000 systems via an Ethernet cable connection. Networked in this way, the client can detect, control and configure the REGARD 3000 units as satellites.

Flexible options for mounting

​Do you already have a control cabinet or control station for your production process control system and would like to integrate the gas warning system there? Or do you need a small gas detection system that can easily integrate into your building? With the Dräger REGARD 3000, you can integrate the docking station directly into a control cabinet and mount the operating unit (display module) in the control cabinet door. Or you can use the innovative, compact wall-mounted housing. You can choose between the colours telegrey and black.
