MaxlogicMavili ML-492L Addressed LPG Gas Detector, Three-Stage Alarm Level

This is an addressed gas detector that monitors LPG leakage in parking garages and similar large enclosed spaces. Alarm thresholds are divided into three stages at 20%, 40%, and 100% LEL, and each stage sends a separate signal to the panel. It provides audible and visual notification while being managed through the addressed gas control center. The three-stage design allows different intervention decisions based on the magnitude of the leak.
