Product Information

The Dräger REGARD® 3900 is a standalone, self contained control system for the detection of Toxic, Oxygen and Ex hazards. The control system is fully configurable between 1 and 16 channels, depending upon the type and quantity of input/output boards installed.

Benefits

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.

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.

Robust enclosure

The robust IP65 enclosure enables the installation of the control system at virtually any location within a safe area.
