  • Page 14: Methods Of Smoke Control

    Chapter 1 Smoke control overview Methods of smoke control Smoke control system designers use five methods to manage smoke. They use the methods individually or in combination. The specific methods used determine the standards of design analysis, performance criteria, acceptance tests, and routine tests. The methods of smoke control consist of: compartmentation, dilution, pressurization, air flow, and buoyancy.

    Applications of smoke control methods A disadvantage of the airflow method is that it supplies increased oxygen to a fire. Within buildings, the airflow method must be used with great caution. The airflow required to control a wastebasket fire has sufficient oxygen to support a fire 70 times larger than the wastebasket fire.

  • Page 20 Chapter 1 Smoke control overview If the technique employs modulated supply airflow, a fan provides at least minimum pressure when all stairwell access doors are open. Either a single-speed fan with modulating bypass dampers or a variable frequency drive varies the flow of air into the stairwell to compensate for pressure changes.

  • Page 21: Elevator Shaft Smoke Control

    Applications of smoke control methods Single and multiple injection pressurization techniques The single injection and multiple injection techniques provide pressurization air to a stairwell (Figure 6). Both techniques use one or more pressurization fans located at ground level, roof level, or any location in between.

  • Page 22: Atrium Smoke Control

    Chapter 1 Smoke control overview more information about elevator shaft smoke control, refer to Klote, J.K., and Milke, J.A. (Design of Smoke Management Systems, 1992). Atrium smoke control Atrium smoke control uses buoyancy to manage smoke in large-volume spaces with high ceilings. The buoyancy of hot smoke causes a plume of smoke to rise and form a smoke layer under the atrium ceiling.
  • Page 23 Applications of smoke control methods Natural smoke venting technique The natural smoke venting technique employs vents in the atrium ceiling or high on the atrium walls to let smoke flow out without the aid of fans (Figure 8). The applicability of natural venting depends primarily on the size of the atrium, the outside temperature, and the wind conditions.

  • Page 24: Underground Building Smoke Control

    Chapter 1 Smoke control overview Underground building smoke control The smoke control objective for underground buildings is to contain and remove smoke from the alarm zone. The smoke control system fully exhausts the alarm zone and provides makeup air to replace the exhausted air.

    Smoke detection and system activation Zoned smoke control detection and activation Zoned smoke control activation occurs on a signal from either a sprinkler water flow switch or a heat detector. For maximum benefit, the zoned smoke control system should only respond to the first alarm. Two design techniques that prevent detection of smoke in zones other than the first zone reporting are: •...
  • Page 26 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.

    Design approaches to smoke control Design approaches to smoke control Smoke control methods provide a mechanical means of directing smoke movement in an enclosed space. The application of one or more methods to a building provides a building smoke control system. Design approaches to smoke control include the no smoke, tenability, and dedicated system approaches.

    Configure each analog output and universal input using a LonTalk ser- vice tool, such as Trane’s Rover service tool. The service tool requires the Tracer MP581 software plug-in to configure an EX2. EX2 modules receive their configuration information from the Tracer MP581 controller they communicate with.

    Chapter 7 Programming Programming occurs after hardware installation is complete. The smoke control system must be programmed for automatic response, weekly self- testing, end-process verification, and response to manual FSCS commands. Response times Time response requirements must be kept in mind when programming. They are give in Table 27.

    Chapter 7 Programming In general, the BCU cannot pass information faster than every 5 seconds. This is the fastest a CPL routine can run. A BCU is included to collect system events, such as communication failure, and allow a user a remote connection to the system for status.

  • Page 116 Chapter 7 Programming From requirements 33.2.1 and 33.2.2, we can see that there is a decoupling between annunciation and reaction. The series of network variables shown in Figure 54, nvoSwitch05 through nvoSwitch12, are used to directly control the smoke alarm LEDs on the FSCP. For example, a smoke alarm for floor 1 is received.

    Chapter 7 Programming Communication watchdog Since multiple Tracer MP581s are used to interface with the mechanical equipment and FACP and FSCS panels, checking communications between each MP581 and BCU is necessary. Three different communication systems are used: BCU to MP581 (auto-bind), MP581 to MP581 (custom bind), and MP581 to EX2.

    Chapter 7 Programming Lamp test and audio alarm silence A lamp test must be performed for every FSCS panel. This test will cause all indicator lights to come on. However, an alarm takes precedence over the lamp test. Figure 68 shows a TGP program fragment that will enable a lamp test relevant to its own LEDs while broadcasting a lamp test request to other Tracer MP581s.

    Chapter 7 Programming 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.

    Variable-air-volume system Variable-air-volume system For variable-air-volume (VAV) systems, some form of duct pressure relief is required on each floor or in each smoke control zone. In smoke control mode, all return and supply fans will be set to their highest speed. If the VAV dampers are closed when this occurs, the duct pressure may be enough to damage the ductwork.

    Chapter 8 Network variable bindings Overview The LonTalk communications protocol allows data to be shared between devices (stand-alone or with a BAS) on a LonTalk network. This is called peer-to-peer communication. As an example of peer-to-peer communica- tion, two or more devices serving the same space share data, such as a temperature reading, without having to pass the data through a BAS.

Only “generic” network variables, which are neither Space Comfort Controller (SCC) or Discharge Air Controller (DAC), are necessary. Use of generic variables does not affect either BCU auto-bound network variables or SCC or DAC based network variables.

    Custom bindings Custom bindings A distinction is made between FSCP and mechanical system control in this section. While smoke control panel processing is predictable, mechanical system processing (actuators, feedback validation) is unknown. It is limited to approximately five smoke control zones based on the UUKL-approved smoke control panel.
  • Page 136 Chapter 8 Network variable bindings In Table 31, the term multi-vibrator is used to indicate a network variable whose state is changed regularly. The receiver expects this value to change state within a certain interval. If it does not, a communication fault is generated.

    Nodes can be any LonTalk-compatible devices, such as appliances, switches, sensors, Tracer MP581s, and Tracer Summit BMTX BCUs, that are connected to a Trane LonTalk network. For the purposes of a UUKL- compliant system, a node is either a Tracer MP581 or a Tracer Summit BMTX BCU.
