Associated equipment

Smoke dampers are ordered as a complete assembly. They are typically two-position dampers and have end switches that indicate the fully open and fully closed position. The switches are installed in the field. Dampers actuate with two types of control: pneumatic actuation and electrical actuation.

Note:

Switches that are part of the actuator do not provide an acceptable indication of actual damper travel. They only show the operation of the actuator and not the actual position of the damper.

For pneumatically actuated smoke dampers, the operating pressure range (spring range) and the normal position of the damper must be specified. Typically, the normal position will be closed (normally closed). The spring range must be high (8–13 lbs) to give the most close-off force.

Uniform Building Code 905.10.2 requires hard drawn, type L, copper pneumatic piping for smoke control system components. The air source must have automatic isolation valves separating it from pneumatic control devices not used for smoke control. Since the smoke control system will open and close smoke dampers, it may require an air pressure monitoring switch. If air pressure is lost in the smoke damper control lines, the switch transmits a Trouble indication.

For electrically actuated smoke dampers, the operating voltages are 24 Vac and 120 Vac. It is usually not possible to get actuators with DC operating voltages. A spring on the actuator positions the damper if power is lost. The power-loss position is typically the actuator closed (normally closed) position.

The electrical power that operates the smoke damper must be from an emergency power source and is monitored at a point after the last disconnect. The loss of electrical power initiates a Trouble indication.

Fans

Fans need additional control components for smoke control operation. Supply/return fan systems require independent control of fans. Multiple fan system Start and Stop points bypass some safety devices.

VAV systems require the smoke control system to be capable of either commanding the fans to full capacity or a higher capacity than comfort controls would command. High-pressure safeties are not bypassed in smoke control operation. Care must be taken to ensure that increased capacities do not trip high-pressure cutout devices. Excess pressures could deactivate fan systems, making them unusable for smoke control.

Verification of operation equipment

Codes require that the smoke control system provide verification of operation status indications at the FSCS. To accomplish this, the smoke control system provides devices that monitor the actual operation of fans

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.
