The Simplex TrueSite Workstation is a next generation platform that manages an entire fire and life safety network from a single location.  This PC-based graphical command center provides centralized network annunciation, historical logging, report generation, and control of fire alarm network points. TrueSite Workstations can support 7 network loops with as many as 686 Simplex control units and seamlessly integrate competitive systems using an Agency-Listed DACR option. Touch-screen operation combined with an intuitive, 3D graphical user interface and customized, event-specific operator instructions help accelerate emergency response and control your training costs.


The Simplex TrueSite Workstation supports up to 60 concurrent remote client connections and leverages the customer's existing LAN/WAN for remote annunciation deployment.​




  • TrueSite Workstation at a Glance
    - Monitor and control up to 250,000 devices
    - Support seven network loops and as many as 686 panels
    - Monitor any brand of control panel using agency listed digital alarm communicators
    - Store historical data for up to 500,000 events
    - Graphically display information and events on a campus-wide site map and individual building floor plans


  • Fast emergency response and notification: The TrueSite Workstation has been designed for fast, efficient response to critical situations. TrueSite Workstation receives status and event information from devices and control units across the facility fire alarm network. The console alerts operators with colour coded action messages and customizable audio notifications. Event locations are pinpointed on a color, 3D map of the facility and detailed, step-by-step response instructions are displayed for the operator to follow. 

  • Simultaneous display of graphical and textual alarm data on up to four display screens: This helps operators quickly assess system activity and respond rapidly to an emergency. TrueSite also includes highly configurable email event notification capabilities, extending the power of the system to mobile and offsite team members.


  • 3D color graphics: With an advanced graphical user interface, the TrueSite Workstation provides touchscreen or mouse-driven access to all system control features. It can import building site plans from CAD drawings and graphically display the location of fire, emergency, supervisory and trouble conditions locations throughout the network. Color coding of events and pan and zoom technology makes it easy to zero in on a specific point of interest. 


  • Seamless integration, outstanding survivability: At a time when interoperability and continuity are more critical than ever, the TrueSite system combines seamless integration with industry leading survivability. Using its Digital Alarm Communication Receiver (DACR) interface, TrueSite can accept alarm information from virtually any control panel. This enables TrueSite to tie together, in an integrated solution, control panels from other vendors as well as panels in locations too remote to be networked.  The TrueSite system is further distinguished by its exceptional survivability. Unlike some other systems, the TrueSite workstation operates as an actual node on the fire alarm network. This architecture has the advantage of providing true peer-to-peer linkage with all panels on the network, thereby fortifying the TrueSite system’s ability to continue operations even if a catastrophic event cripples other parts of the network.

New BSIU Delivers Cost Effective Management for Smaller Facilities

The TrueSite Workstation Building System Information Unit (BSIU) for Simplex systems using ES-Net is ideal for facilities that can benefit from the powerful features of a TrueSite Workstation but do not have the scale, or the budget, for TrueSite UL 864 listed computer hardware and software. 

Thanks to a new application allowed by NFPA 72 (2019 edition) and corresponding changes to UL standards, the BSIU allows us to offer many TrueSite Workstation features and a UL 864 listed software solution that can be run on non-UL 864 listed computer hardware. The use of "off the shelf" computers dramatically reduces cost and makes the TrueSite Workstation much more accessible for smaller or budget-restricted facilities such as schools, clinics, commercial buildings and small residential facilities.
