TOCSIN 920 Controller

The  TOCSIN 920 is a touch-screen gas detection system with flexible control, allowing versatile system design.

The TOCSIN 920 allows up to 250 addressable gas detectors to be controlled.

The controller is designed to work directly with addressable highways and can integrate eight highways as a standard. Additional hubs allow multi-cable options to be accommodated.

Each addressable highway allows up to 32 gas detectors or other input devices to be interconnected. When combined with the T107 addressable relay node, savings can be made on the cost of installation.

Typical applications include car parks, swimming pools, laboratories, schools, universities, road tunnels, refrigeration plant, offshore platforms, refineries, petrochemical processing, the process industry, fuel distribution, gas storage, fuel storage, and garages.
