The Primus V commercial network controller combines gas, heat, and flame detection measurements into a single, coordinated life-safety system. Designed for commercial applications where multiple hazards may be present, the Primus V unifies diverse sensor inputs and translates them into actionable intelligence.
With native BACnet and Modbus capability, the Primus V seamlessly communicates with any facility’s BMS / BAS, enabling real-time coordination between detection, ventilation, alarms, and facility controls. Using Subcon software (sold separately), operators can configure, monitor, and manage all connected devices from a single interface; eliminating complexity while providing a comprehensive, system-wide view of safety conditions.
The Primus V is more than just a controller; it’s an integrated platform that transforms individual detection points into a cohesive, responsive safety ecosystem.
