Warehouse Smoke Control with FSCS Override - Metasys® System Extended ArchitectureApplication Note

Document IntroductionSmoke control applications issue commands to controlled devices that pressurize or depressurize an area of a building to minimize the spread of smoke. This document describes smoke control of a single story warehouse with a rooftop unit in the Metasys system extended architecture. The smoke control strategy is achieved with the DX-9100 (DX) application and the smoke control 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 OverviewThe DX application and the smoke control NAE application both provide smoke control for a single story warehouse with a rooftop unit. The DX controllers provide field connections, and the DX application provides basic HVAC and automatic smoke control for the rooftop unit. 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.

Smoke Control Priority LevelsAll automatic smoke control commands are commanded at Priority 3. Fire fighter manual overrides commanded from the FSCS panel to pressurize or depressurize zones are commanded at Priority 2. Fire fighter manual overrides commanded from the FSCS panel to control individual fans and dampers are commanded at Priority 1. Weekly testing is commanded at Priority 7.

Automatic Smoke ControlAutomatic Smoke Control depressurizes the warehouse. Pressurize and depressurize commands in automatic smoke control are commanded at Priority 3. Priority 3 commands are released when the smoke alarm is reset.

If a warehouse is under smoke control, the FSCS panel turns on status light-emitting diodes (LEDs) to indicate the current status of the fans, dampers and warehouse zone. Status LEDs for a fan show whether the fan is either On, Off, or in Trouble. Status LEDs for a damper indicate whether the damper is either Open, Closed, or in Trouble. Status LEDs for a zone indicate whether the zone is in Pressurize mode, Depressurize mode or Purge mode. The Auto LED 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 the warehouse goes into smoke control. If a fan does not reach its set point within 60 seconds, its Trouble LED is turned on. If a damper does not reach its set point within 75 seconds, its Trouble LED 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.

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.


5

There are two levels of manual smoke control: Priority 2, and Priority 1. Priority 2 is the first level and is initiated when a fire fighter, using the FSCS, puts a zone, the warehouse in this application, in manual smoke control by turning the zone knob to Pressurize, Depressurize, or Purge. All zone smoke control commands are commanded at Priority 2. Priority 2 commands are released when the fire fighter returns the Zone knob back to Auto, or returns the Panel Enable key back to Auto.

Priority 1 is the second level and is initiated when a fire fighter, using the FSCS, puts a point in manual smoke control by flipping either a fan toggle switch to On or Off, or a damper toggle switch to Open or Close. Individual points are commanded at Priority 1. Priority 1 commands are released when the fire fighter either flips the fan or damper toggle switch back to Auto, or returns the Panel Enable key back to Auto.

Any point that is under manual smoke control activates the trouble checking logic and turns on the Trouble LED for that point. If a fan does not reach its setpoint within 60 seconds after the DX issues the command, its Trouble LED is turned on. If a damper does not reach its setpoint within 75 seconds after the DX issues the command, its Trouble LED is turned on. If the Zone switch is set to either Pressurize, Depressurize, or Purge, and a fan does not reach its setpoint within 60 seconds after the DX issues the command, or a damper does not reach its setpoint within 75 seconds after the DX issues the command, the Trouble LED for the fan or damper that failed 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.

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.


6

FSCSThe FSCS panel (Figure 1) is used to control smoke in the warehouse and is responsible for all Sonalert® logic. A Trouble LED is turned on 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 as described in Table 2, and the Sonalert sounds. Pressing the Silence button on the FSCS panel silences the Sonalert and changes the LED to a slow blink. The LED remains on slow blink until it is commanded off. The panel starts a timer and resounds the Sonalert within 24 hours if the 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 is turned on to a fast blink if the panel loses N2 communications.

The Smoke LED for the zone is turned on when a smoke alarm is initiated by an automatic smoke detector in the zone.

The LEDs on the FSCS panel can be set to the following values (Table 2).Table 2: FSCS LED Blink Condition FSCS LED Value LED Blink Condition0 LED is off1 LED is on continuously2 LED slow blink3 LED fast blink and Sonalert turned on

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).

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.

!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.

Figure 2: Assigning the Fire Object to Smoke Control Objects

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

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

Figure 3: Fire Administrator Access Permissions


9

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

4. Fire Limited - This is the lowest of the permissions and only allows the operator to view fire/smoke control devices and alarms.

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 ConsiderationsTake the following design considerations into account when designing your system. In addition, refer to the Metasys System Extended Architecture Smoke Control System Technical Bulletin (LIT-1201684).

• For information on the definition and the initial configuration of this DX-9100 smoke control application and programmable Logic Controller (PLC) modules, use the GX-9100 Graphic Configuration Software Tool (GX Tool) to examine this smoke control application.

You can find instructions and guidelines for using the GX Tool in the GX-9100 Software Configuration Tool Technical Bulletin (LIT-6364060).

• You must define system and object names for all objects.

• The process runs once per second, which is the DX-9100 scan rate.

• You must define the hardware location for each object. This DX-9100 automatic smoke control application does not provide a manual override. Override is available from the operator at the smoke control NAE or the FSCS.

• Most rooftop units have a purge function used when the cooling or heating system ends its On cycle. This should not be confused with a smoke control purge process, or used as such. You can simply reset from Alarm mode back to Monitor mode without running purge.

• An alarm occurs if the command does not equal the condition for any controlled device output, including smoke dampers. Each Binary Output (BO) object for pressurization and exhaust outputs must be configured to have its own feedback (proof sensor) input. The BO’s alarm attribute indicates when command does not equal condition. The alarm attribute must be used in other applications, such as indicating a trouble on the FSCS panel. For smoke dampers, there must be a positive indication of the damper’s fully opened position and its fully closed position. See the response time limitations for alarms in the UL Compliance section that follows.


12

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.

• 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 or to annunciate trouble at the FSCS; 75 seconds for completion of damper travel or to annunciate trouble at the FSCS. 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 is included in 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 Metasys Smoke Control Wiring Technical Bulletin (LIT-1201753).

Smoke Control NAE Design ConsiderationsKeep the following design considerations in mind when designing a warehouse smoke control system:

• 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” BACnet Binary Value object (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 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 if the reset on the IFC panel is pressed.


13

• You must define the hardware location for each object

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

• A DX needs to provide the following 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.

• BV point for AI Fuse.

• BV point for BI Fuse.

• Use the priorities in Table 3 for commands to DX points.Table 3: DX Point PriorityPriority Command Type3 Commands from automatic smoke control2 Commands from manual smoke control for zone pressurize, depressurize, and

purge.1 Commands from manual smoke control for individual points.

Note: The ladder diagram in Figure 20 provides fan control logic for the rooftop supply and exhaust:

• If in normal occupied mode (RTU-OCC) and not in alarm (EXHAUST), and the FSCS Supply Fan switch is in either AUTO (SF-AUTO) or the Supply Fan switch is in override on (SF-OVR), then turn the RTU supply fan on.

• If in unoccupied mode (OCC is off) or in alarm (Exhaust is on), and the Supply Fan switch is not in override, then shut down the supply fan.

• If in normal occupied mode (RTU-OCC), or in alarm (EXHAUST), and the FSCS Exhaust Fan switch is in either AUTO (EF-AUTO), or, override on (EF-OVR), then turn exhaust fan on.

• If in unoccupied mode (OCC is off) , then shut down the exhaust fan.

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: Warehouse and FSCS. The Warehouse section shows logic and configuration screens for pressurization and exhaust logic, lock alarms, latched alarms, and alarm lockout interlock settings for the warehouse. The FSCS section shows the logic and configuration screens for each of the smoke control devices the FSCS controls and/or displays status for. These devices include Exhaust Fan 1, Supply Fan 1, Zone Switch, Zone Smoke LED, and Fire Fighter Control.

Zone Smoke LED - 3rd Party Zone Trouble Interlock DefinitionThe 3rd Party Zone Trouble Interlock Definition (Figure 39) contains an optional, third-party, normally open (N.O.) contact input connection, and a point to monitor the DX offline status. If the third party point goes unreliable or the DX monitoring the third party point goes offline, the Zone LED is turned on.

FSCS Zone Switch LogicThe FSCS Zone Control Switch main logic inputs (Figure 40) from the FSCS are Zone Pressurize, Zone Depressurize, Zone Purge, and Firefighter Control switch. Inputs from the DX are Zone Pressurize and Zone Depressurize. Outputs are the Pressurize, Auto, Depressurize, and Purge LEDs on the FSCS panel and the Zone MCO.

The Zone Control system block logic (Figure 41) controls the FSCS Zone LEDs for the zone, depending on the Fire Fighter Control Key setting.

The Zone Purge LED is turned on if the pressurize and depressurize points in the DX are true.

Figure 39: 3rd Party Zone Trouble Interlock Definition

Figure 40: Zone 1 Control Switch Main Logic


35

The Zone Pressurize LED is turned on if the DX pressurize point is true and the depressurize point is false. The Zone Depressurize LED is turned on if the DX depressurize point is false and the pressurize point is true.

The Zone Auto LED is turned on only if the Zone Switch on the FSCS panel is not set to Pressurize, Depressurize, or Purge.

The Zone Pressurize, Zone Depressurize, and Zone Purge settings on the FSCS panel are not functional unless the Fire Fighter Control Key has been turned on.

If the Fire Fighter Control Key is off, the FSCS Request is set to 0. If the Fire Fighter Control Key is on, the FSCS Request is set to the values shown in Table 8, depending on the position of the Zone switch.Table 8: FSCS Zone1 Switch FSCS Request State ValueFSCS Zone 1 Switch Position FSCS Request
