Gas controllers GA-220.LI.01/02 are designed to control 1 or 2 gas sensors for explosive, toxic or refrigerant gases. They signal light and sound when passing the alarm levels and switch relay outputs. Have 2 alarm levels with LED indication and differential audible alarm depending on the alarm level, relay outputs.

Features:
"TEST" mode. Possibility for external rechargable battery. "RESET" mode deactivates triggered alarm relay outputs for 2 min. Housing for panel mounting allows installation together with the overall system of building automation. Gas controller GA-220.LI compatible with gas sensors GS-220.B.V. ATEX certified  .

Gas controller GA-220.LI.01/02 must be mounted outside controlled areas where possible leakage of explosive, toxic gases or refrigerants. They are certified to ATEX requirements and are suitable for use in the production, processing, storage and sale of fuels, industrial production - using organic solvents, boiler rooms, storage spaces, production and storage of paints and chemicals, control of refrigeration systems and others.
