Response times

Response times

Response times are a pre-installation consideration. For a discussion of response time requirements for smoke control systems, refer to NFPA 92A (NFPA 2000, Recommended Practice for Smoke Control Systems), section 3.4.3.3 and NFPA 92B (NFPA 2000, Guide for Smoke Management Systems in Malls, Atria, and Large Areas), section 4.4.4. The activation sequence should be accomplished so as to avoid damage to the equipment. For example, the dampers should be opened before starting the fans. Table 7 shows the required response times, as published in the referenced NFPA documentation.

Table 7. NFPA response time requirements

Component

Response time

 

 

Damper operation to desired state

75 seconds

(open or closed)

 

 

 

Fan operation to desired state

60 seconds

(on or off)

 

 

 

Note:

Some building codes such as the Uniform Building Code have much more stringent response times. As with all of the considerations discussed in this chapter, the local authority having jurisdiction (AHJ) has the final word.

Cable distance considerations

Table 8 on page 30 given cabling distance requirements for data of two different types:

•Hardware based, such as from analog or binary inputs and outputs

•Communication based, such as from the Lontalk communication link or I/O bus (EX2)

The table also presents different cabling distance requirements depending on whether the data path is monitored or unmonitored.

There are no stated distance limitations for monitored information paths. The maximum distance allowed is the same as the manufacturer’s stated maximum distance for that particular data type. A data path is considered monitored if some notification for opens, ground-shorts, and conductor shorts is available and used (NFPA 72A [2002] section 4.4.7.1).

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.
