Chapter 1 Smoke control overview

Note:

Atrium smoke control should not activate on signals from sprinkler water flow switches or heat detectors. Since the temperature of a smoke plume decreases with height, activation by these devices may not provide reliable results.

Beam smoke detectors minimize interference problems created by stratified hot air under atrium ceilings. On hot days or days with a high solar load on the atrium roof, a hot layer of air may form under the ceiling. The layer can exceed 120° F (50° C). The smoke from an atrium fire may not be hot enough to penetrate the layer and reach ceiling- mounted smoke detectors (Figure 9).

Beam-detector installation typically conforms to one of two configurations: vertical grid or horizontal grid.

Figure 9: Sample stratification

Vertical grid

The vertical grid is the most common beam detector configuration. A number of beam detectors, located at different levels under the ceiling, detect the formation and thickening of a smoke layer. The bottom of the grid is at the lowest expected smoke stratification level.

Horizontal grid

The horizontal grid is an alternate beam detector configuration A number of beam detectors, located at different levels under the ceiling, detect the rising smoke plume. Beam detectors are located:

•Below the lowest expected smoke stratification level

•Close enough to each other to ensure intersection with the plume

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.
