Chapter 2 Pre-installation considerations

and dampers: status switches, differential pressure switches, airflow paddle switches, current-sensing relays, limit switches, and end switches.

Status switches at fans and dampers monitor the operation of the devices. Multiple binary inputs at the Tracer MP581s verify the On and Off status of fans and the Open and Closed status of dampers. If a status switch does not confirm the commanded (automatic or manual) operation, a Fail indicator activates at the FSCS. Failure detection must incorporate a time delay to give the devices time to function.

Differential pressure switches, airflow paddle switches, and current- sensing relays monitor fan operations. Differential switches piped across fan and paddle switches in the air stream can give erroneous indications.

IMPORTANT

A current-sensing relay is the preferred way to confirm the operating status of a fan.

Limit switches and end switches monitor dampers. The switches activate damper Open and Closed signals for the FSCS. The damper blades activate the switches. Some codes require two switches in order to sense both the fully opened and fully closed position of the damper.

Tracer MP581 programmable controller

The Tracer MP581 must have multiple binary inputs to verify the On and Off operation of fans. It must also have multiple binary inputs to verify the Open and Closed positions of dampers.

Equipment supervision

Equipment supervision is a pre-installation consideration. Smoke control equipment must be supervised to ensure it is operational. Supervision techniques consist of confirming communications among system control panels, confirming operation in normal use situations, and performing weekly self-tests.

Confirming communications among all system control panels is a supervision technique that monitors basic system integrity. If any panel loses its communications, a Trouble alert is sent to the FSCS.

Normal use operations confirm the integrity of field point wiring for nondedicated equipment. Nondedicated equipment provides conditioned air to the building daily. When nondedicated equipment is not operational, comfort conditions deteriorate and building tenants notify maintenance personnel.

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.
