Smoke Control Wiring Overview
For Metasys® system field wiring to comply with the National Electrical Code
(NEC) and National Fire Protection Association (NFPA) specifications for smoke
control systems, separate power-limited wiring from non-power-limited wiring as
specified in NFPA 70, National Electrical Code. Field wiring terminals used for
power-limited wiring must be labeled as such. If terminals are not labeled, they are
regarded as non-power-limited.
3
Metasys® System Extended Architecture Smoke Control Wiring Technical Bulletin
Some Metasys system hardware may be used in both power-limited and
non-power-limited circuits. These circuits must be segregated during system
design to comply with the appropriate codes. The wiring system must be designed
in groups, with each Field Terminal Board (TBF) bay being chosen to house all
power-limited or non-power-limited field wiring. See the Wiring Segregation
section in this document for details on wiring segregation requirements for
Metasys system extended architecture products.
In order to meet the requirements of Underwriters Laboratories, Inc.® (UL) under
UL 864 UUKL Smoke Control, some of the Metasys system field wiring must be
protected by installing transzorbs or Metal Oxide Varistors (MOVs). This
protection is only required if the field wiring to the monitored and controlled
equipment leaves the room where the controller is installed. A more detailed
description of the requirements including tables showing which point types require
protection may be found in the Metasys Field Interface Point Types section in this
document.
Isolate the Smoke Control System on a dedicated backbone. If you are using an
existing backbone, consult the customer’s Information Technology (IT)
department to physically isolate the backbone.

As with other types of systems designed and installed to protect life and property,
the responsibility for approving equipment, installations, and procedures lies with
the local Authority Having Jurisdiction (AHJ). The phrase Authority Having
Jurisdiction refers to the agency or individual responsible for approving
equipment, an installation, or a procedure and giving permission to occupy a
building.
Metasys® System Extended Architecture Smoke Control Wiring Technical Bulletin

In most municipalities, that responsibility lies with the fire chief, fire marshal,
electrical inspector, or others having statutory authority. Become familiar with the
building codes of your community as their requirements may differ from those of
the NFPA.
Other entities, such as an insurance carrier or hospital accreditation organization,
may have influence and/or right of approval of the configuration of the smoke
control system.
Smoke Control System Requirements per UL 864 UUKL
The following requirements must be followed in configuring and assembling a
Metasys Network in order to comply with the UL 864 UUKL Smoke Control
Listing:
6
•
All field wiring must be done in compliance with the Metasys System Extended
Architecture Smoke Control Wiring Technical Bulletin (LIT-1201753).
•
The Ethernet card used for connecting the NU-NCM350-8 to the N1 Local
Area Network (LAN) must be the NU-ETH101-0 (available directly from
Johnson Controls).
•
A UL 864 UUKL Listed Firefighters’ Smoke Control Station (FSCS) must be
used to provide manual control of smoke control systems. The UL Listed
annunciator panel, made by Automation Displays, Inc., is the UL Listed FSCS
for the Johnson Controls Smoke Control System..
•
Each Binary Output (BO) object, used for pressurization and exhaust control
outputs, must be configured with positive feedback which monitors the
associated controlled equipment status. Typically, smoke control dampers
provide a pair of feedback binary inputs for the two damper end switches. For
fans used for smoke control, provide positive indication of airflow with either a
flow switch or static pressure sensor to determine the On/Off status of the fan.
•
Positive indication on the FSCS of the operation of all smoke control
equipment must be provided, such as both the open and the closed damper end
switches for each smoke damper, airflow measurement, or static pressure
measurement for each smoke control fan.
•
When any smoke control equipment does not respond to automatic or manual
commands, this trouble condition must be visibly and audibly indicated on the
FSCS.
•
The FSCS controls the Sonalert logic for all smoke control systems; no extra
application is necessary.
•
The Weekly Testing of Dedicated Stairwell Pressurization Fans - Metasys
System Extended Architecture Application Note (LIT-1201739) application
must be used on all dedicated smoke control systems.
Metasys® System Extended Architecture Smoke Control Wiring Technical Bulletin
•
The status of all smoke control systems must be displayed simultaneously on
the FSCS. Once a system has been accessed, you must display on the FSCS all
control points (fans, dampers, and so forth) in that system simultaneously.
•
Duct smoke detectors are often located in the return duct of a Heating,
Ventilating, and Air Conditioning (HVAC) fan and connected to stop the fan
when smoke is detected, which is in compliance with NFPA 90A. However, if
the fan is used for smoke control, and the smoke control strategy is such that
the return duct is configured to exhaust smoke from the building during the
smoke control system operation, then the duct detector should be prevented
from stopping the fan, once the smoke control system has been activated.
•
Automatic activation of any smoke control sequence of operation must have
priority over any automatic environmental control strategy and over any
non-smoke control manual commands. When an automatic smoke control
sequence is initiated, the system design must bypass the following operational
overrides:
-
High and Low Temperature Protection Devices (i.e., A-11 and A-25 Series
Temperature Protection Devices)
-
Return and Exhaust Air Duct Smoke Detectors
•
Manual activation or deactivation of any predefined smoke control strategy
from the manual override station must have priority over any automatic smoke
or environmental sequence of operation. The FSCS serves as the manual
override station.
•
To protect against signal transients, use an American Power Conversion
(APC®) ProtectNet® model PNET1 Ethernet/token ring port surge protector
on each end of the copper lines with RJ45 connectors. Contact American
Power Conversion at 1-800-800-4272. A transient surge suppressor is not
needed if the line stays in the same room as the two devices it connects and is
less than 20 feet (6 meters) long.
•
Use a Tripp Lite® ISOBAR®8ULTRA power line surge protector or a Tripp
Lite IBAR®12ULTRA power line surge protector on all 110-120 VAC power
sources. Use one of these two surge protectors on all devices in the smoke
control system that use AC power (including AC to DC adapters). Contact
Tripp Lite at www.tripplite.com.
•
After an alarm is received and acted upon automatically by the smoke control
system, additional alarms must not cause the smoke control system to take
automatic secondary actions. However, the system will execute any manual
commands from the FSCS.
•
All communication links between buildings must be fiber-optic cable or copper
cable buried in a conduit that is separate from power wiring.
Metasys® System Extended Architecture Smoke Control Wiring Technical Bulletin

•
Response time for individual smoke control components to achieve their
desired operational state should not exceed the following time periods:
60 seconds for fan operation at the desired state plus 10 seconds to annunciate;
75 seconds for completion of damper travel plus 10 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
issuance of an appropriate command to the equipment.)
•
In smoke control applications, you must reserve Priority 2 commands for BOs
used for smoke control functions, such as fan and damper control. All other
non-smoke control logic should use lower command priorities.
•
To design a smoke control system that sends commands across the N1 LAN,
you must use the NAE/NIE to interface all input and output smoke control
points.
DX-9100 Controller Application Requirements
The following requirements apply when using hardwired DX-9100 controller
applications:
8
•
A DX base with transient protection devices (Metal Oxide Varistors (MOVs)
must be used. The Johnson Controls product code number for the DX base
with MOVs is DX9100-8990F.
•
All alarm input Digital Inputs (DIs) must be monitored and report critical
alarms at the FSCS when they close (turn On), such as a fire alarm control
panel smoke detector alarm point.
•
You must monitor the fuse on the DI circuit of each DX-9100 controller when
the DI is used for smoke control. To do this, connect a jumper wire across one
spare DI, so that it will always indicate an On condition. If the fuse fails, this
point will go off, indicating a fuse failure. Map this point to the FSCS directly
connected to the NAE as a critical alarm with a normal state of Closed (On).
•
Any time that you use Analog Outputs (AOs) in your configuration for smoke
control, you must monitor the fuse on the AO. To do this, set one AO for
voltage and define an Analog Input (AI) for voltage. Connect Analog
Constants (ACs) set for 50.0 to the AO that is ranged for 0–100. This gives the
AO a 50 percent signal or a 5 volt output. This output is hardwired to the AI
defined for voltage with a range of 0–100 and a low limit of 20. If the AO fuse
blows, the voltage will go to 0 and the AI will go into low alarm. This alarm
must be monitored as a critical alarm.
•
Any DX-9100 controller used in a smoke application must have a Metasys
system poll priority of 1 or 2.
Metasys® System Extended Architecture Smoke Control Wiring Technical Bulletin
•
All fans controlled by the DX-9100 controller must have an airflow status
switch. Any mismatch of command and HVAC equipment controller status of
the fans must report a critical alarm at the FSCS.
FSCS Requirements
Requirements of an FSCS include the following. The FSCS must:
•
have full monitoring and manual control capability over all smoke control
systems and equipment
•
have the capability to override (partially or in full) any operation in progress,
including programmed actions, non-smoke control manual overrides, and
non-smoke control bypasses
•
have highest priority over all smoke control systems and equipment
•
have a building diagram clearly indicating the type and location of all smoke
control equipment
•
have indication of the actual status (not the command status) of systems and
equipment used for smoke control. This includes both the full open status and
the full closed status of each smoke control damper, the status of each fan used
for smoke control.
•
activate an audible signal if the operation proof sensor (binary feedback point)
failed to provide positive feedback that its command was executed within the
allowed response time
•
have its alarm horn turned on by all hardware supervision alarms, such as
binary feedback alarms on fans and dampers, as well as the system
troublepoints
•
be the only FSCS on a Metasys network used for smoke control applications,
unless multiple FSCSs are approved by the AHJ
Note: Use the UL listed annunciator panel as your FSCS. The panel is available
from:
Automation Displays, Inc. (ADI)

Type 2, Modules Rated as Power-Limited Only
For Type 2 modules (power-limited only), field wiring must be segregated from
non-power-limited wiring. In application specific products, this is not a problem
because all field wiring is power-limited.

Type 3, Modules Rated as Both Power-Limited and Non-power-Limited
(Application Specific)
For Type 3 modules (power-limited/non-power-limited), it is up to the system
designer to ensure that modules are segregated, based on application.
In base frame applications, wiring must be grouped by bays. Each bay in a base
frame must be dedicated as either power-limited or non-power-limited. Base
frames are shipped with a label on each bay stating Power-Limited Field Terminal.
When configuring a base frame and using a bay for non-power-limited field
connections, you must use a permanent black marking pen to cover the wording on
the label. The only bays that should display this label must be totally dedicated to
power-limited field wiring. Bays that do not display this label must be totally
dedicated to non-power-limited field wiring. In no case should power-limited field
wiring be mixed with non-power-limited field wiring.
The XTM/XPx-xxx product line has labels displaying whether it is power-limited
or non-power-limited. For the XPx modules shown in Figure 4, if the field wiring
is non-power-limited, the power-limited label must be covered with a black
permanent marking pen as explained above. For a specific module, only one type
of wiring may be used per side on the module.

Input/Output (IO) Wiring Transient Protection
Requirements
UL 864 UUKL Smoke Control Listing requires that any field I/O wire, from
monitored or to controlled equipment, respectively, that leaves the room in which
the controller is mounted, must be able to withstand signal line transient of
2400 volts and energy levels not less than 0.03 joule or greater than 1.2 joules. To
meet this requirement, some of the Metasys system field wiring must be protected
by either transzorbs or MOVs. If the hardware you are using is not mentioned in
the following sections, no transient protection is required.
When installing the transient protectors (MOVs, transzorbs), care must be taken
when installing a protector in close proximity to other protectors. Before installing
the protective device in the terminal block, twist it together with the field lead and
insert it into the terminal block as one wire. Twist the wire tightly around the
transient protection device a minimum of two turns before inserting it into the
terminal block.
