Single-Point Gas Alarm System NV-120Cv New-Cosmos Vietnam

New Cosmos NV-120 Series – Single-Point Gas Alarm & Indicator System

The NV-120 Series from New Cosmos is a high-performance gas alarm & indicator system designed to monitor a single gas detection point with reliability, flexibility, and smart features. It displays gas concentration, triggers alarms, and supports integration with controllers or safety systems.

🔧 Key Features & Functional Highlights

Modular Connectivity: The NV-120 unit works in tandem with a gas detector (diffusion or extractive type), displaying concentration levels and triggering audio-visual alarms when thresholds are exceeded.
Dual Alarm Stages & Fault Detection: Provides two levels of gas alarm plus a fault output (LED, buzzer, voice message) for early warning in case of equipment or sensor issues.
Analog Output (4-20 mA): Each unit offers a 4-20 mA analog signal proportional to gas concentration, enabling connection to PLCs, recorders, or SCADA systems.
Power & Backup Options: Standard units can be powered via 100-240 VAC or optional 24 VDC. Some models support integrated backup batteries to maintain monitoring during power cuts.
Intermittent Monitoring Capability: In battery-powered units, after main power loss the system continues full monitoring for ~120 minutes, then switches to intermittent monitoring (10 s monitoring every 15 min) under specified conditions.
User Interface & Controls: LCD bar graph display, menu-driven settings for zero/span adjustments, maintenance mode, alarm delays, and language support for voice messages.
Compact & Flexible Installation: Available in both wall-mounted and panel-mounted forms, with dimensions optimized for industrial panels.
Fault Self-Diagnostics & Error Codes: The system self-monitors internal health and displays error codes with corrective guidance.
