Gas Sense Controller Units
The Gas Sense range of controller units includes the GA-ADR addressable controller and the GA-300 series of two-channel and four-channel analogue controllers.
The Gas Sense range of controller units includes the GA-ADR addressable controller and the GA-300 series of two-channel and four-channel analogue controllers.
The GA-ADR addressable controller offers easy setup and flexible operation. Connect, monitor and configure up to 247 detectors on a single Modbus serial line. Create automation zones and expand the system through our modular architecture.
The GA-300 controller is an easy-to-use, cost-effective solution for projects that require 1-4 detection zones. It is a highly reliable analogue unit, equipped with all necessary functionality for industrial and commercial detector monitoring.
The Gas Sense range of controller units includes the GA-ADR addressable controller and the GA-300 series of two-channel and four-channel analogue controllers. Both models are available for DIN-rail mounting or in panel configuration.
The GA-ADR and GA-300 series controller units offer in-built sound and light signalization, integrated relay outputs and continuous detector diagnostics with universal compatibility across the entire Gas Sense range of fixed detectors.
