How Does the V3 / VAS Gas Detection System Work?
1. Field detector: The New Cosmos gas detector measures the target gas with a suitable sensor and transmits its model-specific electrical signal. 2. V3 indicator: displays the gas concentration on a 50-segment LED bargraph; signals alarm and fault conditions. 3. VAS alarm unit: connects to facility safety functions via audible alert and two-stage alarm contacts in a suitable installation.
V3-M, KD-12 and PD-12: For suitable 4–20 mA output versions of KD-12 / PD-12, the V3-M option is evaluated. Types V3-H, V3-C or V3-T are not considered direct equivalents. Suitability must be confirmed via detector model code, cabling and delivery specifications.
From an operational perspective, its advantage is that it provides point-based gas monitoring, maintenance mode and centralized alarm organisation in existing industrial panel infrastructures. In installations across OIZ facilities, natural gas lines, chemical, metal, energy and process industries, it is addressed alongside project requirements.
V3-M CE, Alarm Safety and Maintenance Notes
CE scope: The V3-M CE document on this page does not imply automatic conformity for every V3 variant and every metal housing combination. The manufacturer instruction manual specifies that the housing configuration designated with V3-M is CE-certified. Prior to ordering, the current document, product code and housing combination must be verified together.
Maintenance modeallows external alarm outputs to be managed during servicing and calibration in a suitable system configuration; it does not substitute for periodic functional testing and calibration of the detector. Alarm levels and ventilation/plant shutdown scenarios must be designed in accordance with the installation risk analysis.
Manufacturer Resources and Technical Documents
Links to the NOVEL brochure, Turkish catalogue, English instruction manual and V3-M CE document at the top of the page have also been retained.
Gas Detection and Standards Approach
Control and alarm system approach: In fixed gas detection systems, the detector, control/indicator unit, alarm outputs and field automation must be evaluated as an integrated whole. EN 50271 and relevant EN/IEC 60079-29 series standards may serve as references in application and system design; model-based conformity must be verified with the manufacturer's current certificates. The V3-M document should not be interpreted as ATEX certification or certification belonging to the entire V3 series without verifying the model/metal housing combination.

Frequently Asked Questions About New Cosmos V3
Is the New Cosmos V3 a gas detector or a gas alarm indicator?
V3 is not a gas sensor on its own. It is an indicator unit that displays the measurement signal from the compatible detector in the field. It operates as part of a fixed gas detection system alongside the VAS alarm unit and suitable control outputs.
Can the V3-M indicator operate with KD-12 and PD-12 detectors?
V3-M can be evaluated for suitable 4–20 mA output KD-12 and PD-12 configurations. The detector's exact model code, signal type, power supply, cabling and required CE combination must be verified prior to ordering.
What is the difference between V3-H, V3-C, V3-T, V3-D, V3-O and V3-M?
Hv/Hi is for hot-wire semiconductor, Cv/Ci for catalytic combustion, Tv/Ti for thermal conductivity, D for electrochemical, O for galvanic oxygen, and M for suitable analogue signal inputs. Input connections of the models are not identical.
Is the V3-M CE certificate valid for all V3 models?
No. CE conformity depends on the specific indicator, metal housing and version combination. Order-specific verification must be conducted based on the V3-M CE document on the NOVEL page and current manufacturer documentation.
Are V3 and VAS the same device?
No. V3 is an indicator that displays gas concentration and alarm status. VAS is an alarm unit that provides audible warning, two-stage alarm and fault contacts in a suitable configuration.
What are the outputs of the V3 alarm panel?
The manufacturer's V3 technical table includes a 4–20 mA analogue output in suitable configurations and dry contacts for alarm/fault. Output and wiring details must be verified according to the selected indicator, detector and system schematic.
Where is the V3 gas indicator used?
It can be used to monitor signals from fixed gas detectors on panels in industrial facilities; within gas alarm systems in OIZ, energy, gas infrastructure, petrochemical, automotive and metallurgical plants.
Does V3 maintenance mode substitute for gas detector calibration?
No. Maintenance mode helps manage alarm outputs following the appropriate procedure during servicing. Functional bump testing with gas and calibration of the detector must be performed separately in accordance with manufacturer instructions and facility maintenance schedules.
