Dräger REGARD 3900
The Regard 3900 is a standalone, autonomous control system for up to 16 gas detectors. It is fully configurable and monitors the concentration of toxic gases, oxygen and combustible gases and vapours.
Product features
- Flexible design
-
The Regard 3900 can be equipped with up to four 4 - 20 mA input cards. Each input card can be connected to up to four gas detectors, either 2 or 3 wire, giving a maximum of 16 gas detectors per each Regard 3900. Each input module is equipped with three alarm relays.
These relays are designated as common alarms for the corresponding input card for "Fault", "1st alarm" and "2nd alarm". The 1st and 2nd alarm relays are fully configurable and can be set up as rising or falling and latching or non-latching.
In addition, the Regard 3900 can be equipped with up to two relay modules. Each relay module has eight additional relays.
In accordance with the ATEX directive, the first relay is always configured as a fault relay and cannot be changed. The other seven relays can be configured as individual, common or voting alarms. They can either operate as normally open or normally closed relays.
The alarm relays are acknowledged by operating a button at the front of the control unit. - Robust enclosure
- The robust IP65 enclosure enables the installation of the control system at virtually any location within a safe area.
- Quick and easy configuration
- The Config 3900 configuration software enables quick and easy configuration via a laptop or a PC. With new installations, the configuration can initially be carried out online and then loaded during commissioning. During maintenance the system configuration can be downloaded from the device to a PC for checking. The appropriate connection cable and the required software are available as accessories.

List of detectable gases and vapours.
For over 70 years, Dräger has been one of the technology leaders in gas detection.
When there’s danger in the air ... this can quickly pose a high risk to humans, the environment, and all types of property and systems. Recognize the threat before it is too late.
Safety Instrumented Systems are used to reduce the risk for the protection of people, plants, and environment.
Explosion hazards mostly arise from flammable gases and vapours. Instead of avoiding their ignition by explosion protection measures it may be preferable to detect them before they become ignitable.
