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.
| Remote I/O Control | Allows operators to remotely manage inputs and outputs for every connected Optio-based monitor. |
| High-Capacity Sensor Support | Accommodates up to 6 sensors per monitor, enabling a single Primus V controller to manage a network of up to 576 total sensors from a single location. |
| Six Integrated Relay Outputs | Includes 6 × 2 A @ 24 VDC, 0.5 A @ 120 VAC Normally Open/Normally Closed relays with optional failsafe mode for reliable alarm and control activation. |
| Local & Remote 4–20 mA Outputs | Offers two local analog outputs plus twelve Modbus-driven remote 4–20 mA outputs for flexible integration. |
| Strobe & Horn Output | Provides a direct output port for local audible and visual alarm devices. |
| Time-Stamped Data Logging | Records all state changes and alarm events with accurate time stamps for compliance and diagnostics. |
| Configurable Multi-Zone Operation | Supports up to 12 unique zones to separate alarm logic and control functions across your facility. |
| Flexible Communication Options | Integrates with building automation systems and building management systems (BAS / BMS) via BACnet, Modbus RTU, analog 4–20 mA, and relay outputs. |
