Multi-Story Building Smoke Control with FSCS Override - Metasys® System Extended ArchitectureApplication Note

Document IntroductionSmoke control applications issue commands to controlled devices that pressurize or exhaust an area of a building. This document describes smoke control for a multi-story building with floor above/floor below pressurization in the Metasys® system extended architecture.

The smoke control strategy is achieved with the DX-9100 (DX) application and the smoke control Network Automation Engine (NAE) application described in this document, with manual override of the smoke control logic provided by the Fire Fighter’s Smoke Control Station (FSCS).

Note: These application notes only present an example of one smoke control strategy. Since every building is unique, the details of applying the strategy vary. These application notes can help you develop an appropriate application for your project.

Application OverviewThis application provides smoke control for a multi-story building. The application logic provides automatic smoke control, floor above/floor below pressurization and exhaust, stairwell and elevator pressurization, and fire fighter manual override. The DX controllers provide field connections, and the DX application provides basic HVAC and automatic smoke control for the multi-story building. The smoke control NAE provides a connection to the FSCS, and the smoke control NAE application provides automatic smoke control and fire fighter manual override for the smoke control system.

Automatic Smoke ControlAutomatic Smoke Control provides the logic for UUKL first incident rule by locking out subsequent alarms from automatic smoke control. Floor Above/Floor Below logic depressurizes the floor that goes into smoke alarm. The floor above the alarm, floor below the alarm, stairwell and elevator shaft are pressurized. Pressurize and Depressurize commands in automatic smoke control are commanded at a Priority 3. Priority 3 commands are released when the smoke alarm is reset.

If a floor, stairwell, or elevator shaft is under smoke control, the FSCS controls the Light-Emitting Diodes (LEDs) next to each FSCS switch to indicate the current status of the fans, dampers, and zone. Status LEDs for a fan show the fan status as On, Off, or in Trouble. Status LEDs for a damper show the damper status as Open, Closed or in Trouble. Status LEDs for a zone (store or mall area) show the zone status as Pressurize mode, Depressurize mode, or Purge mode. The Auto LED for each fan, damper, and zone switch remains on while the point is in automatic smoke control.

The logic to check the status of fans and dampers for trouble is initiated when a floor, stairwell, or elevator shaft goes into smoke control. If a fan does not reach its set point within 60 seconds, its Trouble LED on the FSCS is turned on. If a damper does not reach its set point within 75 seconds, its Trouble LED on the FSCS is turned on. After a commanded point goes into Trouble, the Automatic Command Retry logic repeats the command that failed every 60 seconds until the command is successful.

Pullstation LogicPullstations are not allowed to initiate automatic smoke control for individual floors. However, they are allowed to initiate smoke control pressurization for stairwells and elevators.


5

Automatic Smoke Control PrioritiesAll automatic smoke control commands are commanded at a Priority 3. Fire fighter manual overrides, issued from the FSCS panel, to pressurize or depressurize zones, are commanded at a Priority 2. Fire fighter manual overrides, done from the FSCS panel, to control individual fans and dampers, are done at a Priority 1.

Manual Smoke ControlManual Smoke Control logic is initiated when a fire fighter turns the FSCS Panel Enable key from the Auto position to the Fire Fighter Control position and initiates a manual override of a fan, damper, or zone point from the Auto setting on the FSCS panel. This turns off the Panel Enable switch Auto LED, and turns on the Panel Enable switch Fire Fighter Control LED.

There are two levels of manual smoke control. A fire fighter can put a floor in manual smoke control by turning the zone knob to Pressurize, Depressurize, or Purge. The zone smoke control commands are commanded at Priority 2. Priority 2 commands are released when the fire fighter turns the zone knob back to Auto or turns the Panel Enable key back to Auto.

A fire fighter can put a point in manual smoke control by flipping a fan toggle switch to On or Off, or a damper or Variable Air Volume (VAV) toggle switch to Open or Close. Individual points are commanded at Priority 1. Priority 1 commands are released when the fire fighter flips the toggle switch to Auto or turns the Panel Enable key back to Auto.

Any point that is under manual smoke control activates the trouble checking logic. If a fan does not reach its set point within 60 seconds, its Trouble LED turns on. If a damper does not reach its set point within 75 seconds, its Trouble LED turns on. After a commanded point goes into Trouble, the Automatic Command Retry logic repeats the command that failed every 60 seconds until the command is successful.

Auto Command Retry LogicThe Auto Command Retry logic is used for fans, dampers, and VMAs. It does a comparison check between the commanded state and the actual device state, to verify that the command was successful. In the event a command to a fan, damper, or VMA fails, possibly because the MCO for the commanded device is on a remote smoke control NAE panel. The additional time required to communicate with the remote smoke control NAE might exceed the command response limit. Therefore, the command is resent every 60 seconds until the command is successful.

The Auto Command Retry logic is used when either a device MCO does not match command, a fan, damper, or VMA status does not match its commanded value, or a fan, damper, or VMA trouble input is active.

FSCSThe FSCS panel example (Figure 1) shows the manually controlled devices for Floor 6 only, the elevator supply fan, and stairwell supply fan. The devices for Floor 6 are three dampers, a supply fan, an exhaust fan, and a VAV. The LEDs next to each dial or toggle switch (Table 2) designate the status of each device or zone. The Smoke LED indicates a smoke alarm for the zone (floor).The FSCS in this application has six floors and additional controls not shown here.

The LEDs on the FSCS panel (Figure 1) can be set to the following values.

The FSCS panel is responsible for all Sonalert® logic. A Trouble LED is lit when a fan or damper fails to achieve its commanded state, an automatic smoke detector triggers an alarm, or an AI or DI fuse on the DX fails. The LED value is set to 3 or 4, as described in Table 2, and the Sonalert sounds. Pressing the Silence button on the FSCS panel silences the Sonalert and changes the Trouble LED to a slow blink. The Trouble LED remains on slow blink until it is commanded off. The panel starts a timer and resounds the Sonalert within 24 hours if the Trouble LED is not turned off.

The Sonalert sounds if the FSCS Panel Enable key is turned from the Firefighter Control position to the Auto position and all zone knobs and point toggle switches are not set to Auto. The FSCS still goes into Auto mode, but the Sonalert reminds the firefighter to set the manual smoke control switches to the Auto position.

The General Trouble LED turns on to a fast blink if the panel loses N2 communications.

Assigning the Fire Object Category to Smoke Control ObjectsYou must assign every object used specifically for smoke control as a Fire object. This limits the control of smoke control devices and points to authorized Fire operators.

Use the pull down menu to assign the Fire object category (Figure 2).

!WARNING: Risk of serious injury or death if a smoke control object is not assigned as a Fire object! In the event of a fire or smoke control event, devices or points used for smoke control that are not assigned as Fire objects allow those devices and points to be controlled by non-fire authorized operators. It is imperative that every smoke control device or point be assigned as a Fire object.

Security Administration SystemThe Security Administration system authenticates and authorizes users of Metasys® system extended architecture applications. The Security Administrator is a browser-based interface that manages all accounts.

Use the Security Administrator System to authenticate and authorize users on the Metasys system extended architecture. The Security Administrator creates User Accounts and Roles, and assigns access permissions to each user of the Metasys system extended architecture.

Roles and User Accounts OverviewSecurity is based on User Accounts and Roles. Roles are groups of users with a specific function within the Metasys system. To access the system, an individual provides a user account and the correct password. Use letters, numbers, or symbols to create user account passwords.

Use the Login button from the logon prompt to send the user’s credentials. A unique Session generates when the user’s credentials match the logon requirements.

UUKL Smoke Control Security Administration DetailsUUKL smoke control requires that only operators designated as fire operators be able to control the smoke control system. This required the creation of four new roles:

1. Administrator - This is the highest level of control and allows site control of all HVAC and Fire features.


9

2. Fire Administrator - This role is a fire manager level setting. It allows for full system control, including system modification or configuration.

3. Fire User - This role is for most fire field technicians and allows system control and alarm acknowledgement, but not system modification or configuration.

Figure 3: Fire Administrator Access Permissions

Figure 4: Fire User Access Permissions

Design ConsiderationsThis DX9100 and Smoke Control NAE application, as it exists in the Metasys System Extended Architecture Smoke Control Library, complies with the UL 864 UUKL Smoke Listing. However, you are responsible for ensuring that the application complies with state and local regulations, and is approved by the Authority Having Jurisdiction (AHJ). You are also responsible for configuring all of the smoke control components, as well as the programming of those components, in order to comply with the UL 864 UUKL Smoke Listing as documented herein.

DX Design ConsiderationsA DX will need to provide the following BACnet Binary Value object (BV) points:

• Zone Pressurize Command – Set to true to turn on supply fans

• Zone Depressurize Command – Set to true to turn on exhaust fans

• BV Auto point – Normally set to true. Point is false when a fire fighter turns a fan On or Off, or sets a damper to Open or Close.

• BV command point for each fan

• BV feedback point for each fan

• BV command point for each damper

• BV open feedback point for each damper

• BV close feedback point for each damper


12

• BV point for an Analog Input (AI) Fuse

• BV point for a Binary Input (BI) Fuse

Use the following priorities for commands to DX points:

• Priority 3 – commands from automatic smoke control

• Priority 2 – commands from manual smoke control for zone pressurize, depressurize, and purge.

• Priority 1 – commands from manual smoke control for individual points.

• For information on the definition and the initial configuration of the Programmable Logic Controllers (PLCs), use the GX-9100 Software Configuration Tool (GX Tool) to examine this program.

• This application can be expanded for a building with more than six stories. For further details, please contact Field Support Services in Milwaukee.

• You must define tag names for all points.

• You must define the hardware location for each object

• You must name each object with a descriptive name that is unique in the system.

• An alarm occurs if the command does not equal the condition for any pressurization or exhaust output. Each Binary Output (BO) for pressurization and exhaust outputs must be configured to have its own feedback (proof sensor) input. The FSCS indicates when command does not equal condition.

For UL compliance:

• If DX Digital Inputs (DIs) are used for smoke control, then DI8 must be jumpered and mapped to the smoke control NAE as a normal state of On. If DI8 is off, a critical alarm must be issued at the FSCS to indicate a binary input fuse failure that must be fixed immediately, because the DI is no longer accurate.

• If DX Analog Outputs (AOs) are used for smoke control, then Analog Output 14 (AO14, voltage) must be wired to Analog Input 8 (AI8, voltage) and the AI must be mapped to the smoke control NAE with a low alarm limit of 20%. If the AI goes below 20%, it indicates the AO has failed because of a blown fuse, which drops the AO to 0V and the AI to 0% (low alarm). The DX is downloaded so that the AO is normally at 5V because its source point is an Analog Constant (ACO) with a default of 50.


13

• Response time for individual smoke control components to achieve their desired state of operational mode, exclusive of control system response, should not exceed the following time periods: 60 seconds for fan operation at the desired state plus 90 seconds to annunciate; 75 seconds for completion of damper travel plus 90 seconds to annunciate. In the case of fan start after damper close, these times are additive. If the damper must be closed before the fan starts, the total response time could be up to 135 seconds for operation, 75 seconds for damper to close plus 60 seconds for fan to start. Time to annunciate would be added to this time. (Control system response is the time from automatic detection of a smoke condition to the issuing of an appropriate command to the equipment.)

For specific wiring requirements, refer to the Metasys Smoke Control Wiring Technical Bulletin (LIT-1201753).

Smoke Control NAE Design Considerations• The smoke control NAE reports critical alarms based on the alarm condition,

and the alarm can only be cleared by resetting from the Intelligent Fire Controller (IFC) panel or the Firefighter’s Smoke Control Station (FSCS).

• A “Programming In Progress” BV point is required. You must set this point to true any time you are making changes to the Smoke Control system. This turns on the Programming In Progress LED on the FSCS to let a fire fighter know that changes are currently being made, and the system may not be fully functional. The point must be turned off when changes are complete.

• A master reset interlock is required. The interlock is true after you press reset on the Intelligent Fire Controller (IFC) panel.

• Each floor requires a Latched Alarm BV object. The lock alarm logic sets this point to true for the first alarm detected.

• Each floor requires an Alarm Lockout Interlock. The interlock is true if any latched alarms for other floors is true or the master reset interlock is true. Do not include a floors latched alarm in its own Alarm Lockout Interlock.

• Response time for individual smoke control components to achieve their desired state of operational mode, exclusive of control system response, should not exceed the following time periods: 60 seconds for fan operation at the desired state plus 90 seconds to annunciate; 75 seconds for completion of damper travel plus 90 seconds to annunciate. In the case of fan start after damper close, these times are additive. If the damper must be closed before the fan starts, the total response time could be up to 135 seconds for operation, 75 seconds for damper to close plus 60 seconds for fan to start. Time to annunciate would be added to this time. (Control system response is the time from automatic detection of a smoke condition to the issuing of an appropriate command to the equipment.)

Smoke Control NAE ApplicationApplication File Location

This Metasys system extended architecture smoke control application is located on the Metasys Branch Purchase Package (BPP) CD in the Metasys System Extended Architecture Standard Smoke Control Applications directory.

Metasys System Extended Architecture ObjectsThis smoke control NAE application resides on the smoke control NAE and was created with the System Configuration Tool (SCT) to define the required Control System, Interlock, and Multiple Command objects. The Logic Connector Tool (LCT) is used to create the logic within the Control System object.

The LCT logic and configuration screens are organized into two sections: Multi-Story Building and FSCS. The Multi-Story Building section shows logic and configuration screens for the floor above/floor below pressurization and exhaust logic, lock alarms, latched alarms, and alarm lockout interlock settings for the stairwells, elevators, and each of the six floors. The FSCS section shows the logic and configuration screens for each of the devices the FSCS controls and/or displays status for. These devices include the Zone Switch, Damper 1, Supply Fan 1, Variable Air Volume Modulating Assembly (VMA) 1, Zone Smoke LED, Damper 2, Damper 3, and Exhaust Fan 1 for each of the six floors. In addition, the logic and configuration screens for the stairwell fans, elevator fans, and Fire Fighter Control is provided.


23

Multi-Story Building Smoke Control

Floor Above/Floor Below Logic The Floor Above/Floor Below main logic (Figure 13) controls the automatic smoke control. It consists of the inputs, two system blocks, and outputs. The inputs (Figure 14) are one interlock for each floor and a master reset interlock. The Lock Alarms block (Figure 15) locks in the first incident. The All Floors Logic block determines which floors to pressurize and depressurize. Outputs (Figure 16) are binary points within a DX. Each floor has a pressurize and depressurize point.

Figure 13: Floor Above/Floor Below Main Logic


24

The inputs and the Lock Alarms block is shown in Figure 14. Each floor has one smoke alarm interlock. The Lock Alarms block locks in the first incident. The Master Reset Interlock releases the locked alarms. There is an output alarm for each floor. Only the first floor in alarm is set to true. All other floors are set to false.

Figure 14: IFC Alarm Input Points, FSCS Reset Point, and Lock Alarms Block


25

The Lock Alarms block and All Floors Logic block (Figure 15) show the outputs from the Lock Alarms block feeding into the All Floors Logic block, and the resulting outputs.

Figure 15: Lock Alarms and All Floors Logic Blocks


26

The outputs from the All Floors Logic block (Figure 16) connect to zone pressurize and depressurize points in the DX. Stairwells and Elevator shafts also have pressurize points in a DX..

Figure 16: All Floors Outputs to DX Controllers


27

All Floors LogicThe following screens show the expanded All Floors Logic block that includes a system block for each of the six floors (Figure 17), and a stairwell block and elevator block (Figure 18). Each floor logic has an input for that floors smoke alarm, one for the floor above and one for the floor below. Outputs tell the DX to pressurize or depressurize.

Figure 17: All Floors - Floors 1, 2, 3, 4, 5 and 6 Logic


28

The Stairwell Logic block and Elevator Logic block (Figure 18) both have an input for each floor, and one pressurize output.

The expanded Stairwell Logic block (Figure 19) pressurizes the stairwell if any floor is in smoke alarm or a pull station is active.

Figure 20: All Floors - Elevator Pressurization Logic


30

Lock Alarms LogicThe Lock Alarms – All Floors system block (Figure 21) has a lock control system block for each floor. Inputs are that floor’s alarms, an Alarm Lockout Interlock that is true if there is an alarm on any other floor, and a Master Reset Interlock. Outputs feed into the All Floors logic and to the Latched Alarm point. The latched alarm point is input into the Alarm Lockout Interlock for all other floors.

Figure 21: Lock Alarms - All Floors


31

The expanded Floor Lock logic (Figure 22) shows the logic for a single floor. The first latch latches the alarm for that floor until it is reset. The second latch latches the first incident.

Alarm Lockout Interlock LogicThe Master Reset Interlock Definition (Figure 23) releases the locked alarms when commanded by the IFC fire panel Reset button.

The Master Reset Interlock Action Table (Figure 24) sets the Manual Latched Alarm Reset to inactive 60 seconds after the IFC fire panel Reset button is pressed.

Using Multiple Smoke Control NAEs or NIEs

Requirements for Larger SitesThere are larger sites where, due to a large number of objects, several smoke control NAEs or NIEs may be required. If this is the case, then one smoke control NAE must be designated as the FSCS smoke control NAE and must connected directly to the FSCS. A Site Director smoke control NAE is used to monitor all smoke control NAEs and smoke control NIEs.

Object LimitsEach device and its programmed points use objects. There is a suggested object limit of, for performance purposes, 5,000 objects per smoke control NAE/NIE. When approaching the object limit it is sometimes necessary to add additional smoke control NAEs or NIEs.

Site Director Smoke Control NAEThe Site Director smoke control NAE provides the ability to monitor and control all devices connected to the smoke control system.

FSCS Smoke Control NAEThe FSCS smoke control NAE connects directly to the FSCS and monitors the Site Director smoke control NAE.

Smoke Control System Connection OverviewThe example multi-story smoke control system (Figure 99) shows the IFC panels, the FSCS panel , the Site Director smoke control NAE, the smoke control FSCS NAE, a smoke control NIE, and various N1 and N2 devices, communicating over Ethernet and fiberoptic connections.

Figure 99: Example Multi-Story Smoke Control System


90

FSCS AlarmsTable 15 shows the resulting FSCS alarms when any of the devices in the example multi-story smoke control system (Figure 99) go offline.

Monitoring the Site Director Smoke Control NAEThe Site Director smoke control NAE must be monitored by the FSCS smoke control NAE in the event it goes offline. The NAE Site Director Monitor Interlock (Figure 100) is used to monitor the Site Director. If the Site Director smoke control NAE goes offline the FSCS Smoke control NAE detects the offline alarm and sends trouble alarms to the FSCS for any floors, devices, or points being controlled by the Site Director smoke control NAE. .

To monitor the Site Director smoke control NAE:

1. Add a Site Director Monitor point (Figure 101) to the tree in the FSCS folder of the FSCS smoke control NAE

2. Create a folder inside the FSCS folder of the FSCS smoke control NAE for each floor the Site Director smoke control NAE monitors.

3. Inside each newly created floor folder, create a folder for Damper 1, Damper 2, Damper 3, Exhaust Fan 1, Supply Fan 1, VMA 1, and Zone Smoke LED.

Monitoring a Smoke Control NIEEach smoke control NIE must be monitored by the Site Director in the event it goes offline. If a smoke control NIE goes offline the Site Director smoke control NAE detects the offline alarm and sends trouble alarms to the FSCS smoke control NAE for any floors, devices, or points being controlled by the smoke control NIE.

To monitor a smoke control NIE:

1. Add an NIE monitor point (Figure 105) to the tree in the FSCS folder of the Site Director smoke control NAE (Figure 104).
