BIG TOWER is Beinat’s modular and scalable gas detection system designed for the centralized monitoring of large facilities. Thanks to its multilayer architecture and native integration with BMS systems via BACnet, it enables the management of thousands of sensors distributed across multiple buildings.

Composed of ABS16, ABM16, and the SM640 System Manager (Linux-based with touch display), BIG TOWER ensures full control, event datalogging, simplified maintenance, and complete customization for bespoke projects.

Ideal for hotels, residential buildings, supermarkets, schools, offices, and complex applications.
