Nondedicated smoke purge

(UL-864: 3.21.h)

The term nondedicated refers to a system that provides the building’s HVAC functioning under normal conditions and a smoke control objective during a fire alarm condition.

The main concern when designing a nondedicated system is for programming to ensure that, once a smoke alarm or FSCP override occurs, any component of the smoke control system is controlled solely by automatic smoke control or manual override commands. For details regarding priority, see Table 28 on page 101.

Figure 70 shows an example of programming for a nondedicated system to implement the priorities in Table 28. In this figure, the smoke control dampers for Floor 1 are controlled. The actuator position, either Open or Closed, will default to whatever the HVAC system commands. There are two states that will turn control over to either automatic smoke control or FSCP overrides:

If the broadcast general smoke alarm is TRUE, or

If the FSCP override switch is set to either Open or Closed.

BAS-APG001-EN, Engineered Smoke Control System for Tracer Summit specifications

The Trane Engineered Smoke Control System is an advanced solution designed to enhance safety and efficiency in buildings by effectively managing smoke during emergency situations. Specifically tailored for integration with the Tracer Summit Building Automation System, the Trane Engineered Smoke Control System (BAS-APG001-EN) combines cutting-edge technologies with user-friendly features, empowering facility managers to maintain optimal air quality and ensure occupant safety.

One of the standout features of the system is its programmable logic capabilities, which allow for customized smoke management strategies based on building layout and operations. This flexibility ensures that smoke is effectively controlled, providing clear egress paths for occupants while maintaining a safe environment for emergency responders. The system is engineered to operate seamlessly with other building systems, including HVAC and fire alarm systems, enabling a cohesive response during smoke events.

The Trane Engineered Smoke Control System employs sophisticated detection technologies that monitor air quality and detect smoke in real-time. This proactive approach facilitates early intervention, allowing for rapid activation of smoke control measures. Additionally, the integration of variable speed fans ensures that smoke is moved efficiently out of critical areas, reducing the risk of smoke inhalation for building occupants.

One of the key characteristics of this system is its ability to provide reliable, redundant operation. With engineered backup systems in place, the reliability of smoke control measures is significantly enhanced, ensuring that they will function correctly even in the event of a power failure. This is especially critical in high-rise buildings or complex structures, where smoke control is vital to occupant safety.

User interface features included in the Tracer Summit system offer intuitive controls and monitoring capabilities, simplifying the management of smoke control operations. Facility managers can easily view system status, receive alerts, and make necessary adjustments through the user-friendly dashboard, enhancing operational efficiency.

The Trane Engineered Smoke Control System stands out as a premier solution for smoke management in contemporary building designs. By integrating sophisticated detection technologies, programmable logic, and reliable operation, it provides an essential layer of safety in creating environments that prioritize occupant protection. As buildings continue to evolve, Trane’s commitment to innovation ensures that its Engineered Smoke Control System remains a key component in modern fire safety infrastructure.
