Dräger REGARD 3900
The Regard 3900 is a standalone, autonomous control system for up to 16 measuring channels. It is fully configurable and monitors the concentration of toxic gases, oxygen and combustible gases and vapors.
Product benefits
- Flexible design
-
Up to four 4-20-mA transmitters each can be connected to a maximum of four input modules in 2/3 wire technology. Each input module is equipped with three relays.
These change-over relays are designed as collective alarms for the corresponding module for the messages "Fault", "1st alarm" and "2nd alarm". The two alarms 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 two relay modules. Each of these modules has eight relays.
The first relay is always configured as a failure relay and cannot be changed. The other seven relays can be configured as individual, collective or group alarms. They can either operate as a operating current relay or a standby current relay.
Depending on the application and the connected transmitters a third gas alarm and an additional alert can be configured.
The alarm relays are acknowledged by operating a key 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 the Non-Ex range.
- 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.

System Components
The best performance characteristics alongside the greatest flexibility – the gas library of the infrared-optical transmitter Dräger PIR 7000 can be freely configured and offers exceptional linearity for each library substance across the whole measuring range.
Modular design – highly flexible: The universal transmitter Dräger Polytron 7000 measures toxic gases and oxygen and can be optimally adjusted to the most different applications.
Flame detection on the basis of a live video signal. Using a color video signal, the Dräger Flame 5000 detects characteristic properties of flames by means of its digital signal processing and software algorithmics. The Dräger Flame 5000 is approved for use in explosion-hazard areas according to ATEX, IECEx and FM/CFM.
All in one enclosure: The Dräger Polytron 7500 is a pyrolyzer for the continual monitoring of toxic gases and halogenated carbons in the ambient air. The device contains all necessary functions such as sampling, processing and analysis.

Literature
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.
