SmartStruxure Solution Hardware Overview

The SmartStruxure solution hardware includes the Automation Server (AS-SMK), or AS-P (AS-P-SMK), PS-24V power supply, terminal bases, and a variety of I/O modules. The Automation Server (AS-SMK), or AS-P (AS-P-SMK) is the main controller in the system and is always installed with a PS-24V supply forming the minimum configuration.

A selection of I/O modules (described here) is installed with the Automation Server (AS-SMK), or AS-P (AS-P-SMK) to provide inputs and outputs covering a wide variety of I/O types and capacities ranging from 8 channels up to 464 channels (29 I/O modules of the 16 channel type + one additional PS-24V). Hereafter in this document, when the Automation Server (AS-SMK) and AS-P (AS-P-SMK) are discussed together, they will be referred to as Smoke Control Servers.

Each device consists of a terminal base and an electronics module that plugs into the base. The electronics module has two handles, which have to be pulled out when removing the module from or inserting the module to the terminal base. In their inner position, the handles lock the module to the terminal base. This effectively prevents unintentional separation providing tolerance for vibration and jarring as required in UL 864 systems. Wiring connections are made on the terminal blocks contained on the terminal base. The terminal screws are accessible without removing the module. Power for all devices is taken from the 24 VDC rails of the backplane that is part of the terminal base

Terminal Base

Terminal Base

The I/O terminal base provides 2 terminal blocks, while the Automation Server (AS-SMK) has a single terminal block. The AS-P (AS-P-SMK) and power supply terminal bases have no terminal blocks. The I/O, Automation Server (AS-SMK), and AS-P (AS-P-SMK) terminal bases use the same backplane circuit board. Both will pass through (left to right) the 24 VDC power. The power supply terminal base does not pass through the 24 VDC from the left backplane port and injects its output voltage onto the bus extending to the right. This terminates the accumulating load on the previous power supply module and now this PS-24V supplies power to the bus connecting to additional modules connecting on the right side. All of the terminal bases increment the address bus value by one and pass it on toward the right and also to the plug-in electronics module. All terminal bases also pass a high speed RS-485 communications bus from base to base. The RS-485 communications serves all I/O modules and is managed by the single Smoke Control Server allowed to reside on the I/O bus.

The design provides each module position with a unique address based on the position of the module on the I/O bus. This creates an automatic addressing scheme where the electronics module plugged into the terminal base will take on the position based address provided by the base. The first (leftmost) terminal base module starts with address 01. Address 01 is reserved for the initial PS-24V power supply and address position 02 is reserved for the Smoke Control Server. Only one Smoke Control Server is permitted on the I/O bus. The I/O bus extends up to a maximum position address of 32. After the first PS-24V and the Smoke Control Server, the I/O bus supports up to 30 I/O and power supply modules. The PS-24V is rated for 30 watts output and additional PS-24V units must be added on the I/O bus as needed to ensure the load on any power supply units is 30W or less.

Electronics Module Features

There are three type of electronics modules included in the Automation Server module family including the PS-24V Power Supply module, the Smoke Control Server, and 17 models of the I/O modules. All of these modules share the following common features.

Hot-connect and Hot-swap

Because critical applications require 24-hour operation, Schneider Electric designed the electronic modules for hot-connection of terminal bases and hot-swapping of the modules to their bases. This design ensures continuous power and communication during service operations.

Auto-Addressing

The auto-addressing feature eliminates the need for setting DIP switches or pressing commission buttons. With the Automation Server family, each module automatically knows its order in the chain and assigns itself accordingly. This significantly reduces engineering and maintenance time.

Simple DIN-rail Installation

Fasteners easily snap into a locked position for panel installation. The fastener has a quick-release feature for easy DIN-rail removal. The modules use common 35mm DIN rail.

Protection

Protection components on the inputs and the outputs protect against high-voltage, short-duration transient events. The current inputs are protected against over current.

Accommodates Multiple DIN Rail Panel Installations

The Automation Server module family uses built-in connectors for single row connectivity, side by side. If a panel size requires multiple rows, S-cable extension cords are available.

Power Source

The Automation Server module family are all powered by 24 VDC supplied by the PS-24V module, which in turn, is powered by 24 VAC. For UL 864 compliance, the 24 VAC must be provided by one of the approved transformers. For more information, see Transformers

Environment

The module family shares a common environment specification:

  • Storage: -20°C to +70°C

  • Operating: 0°C to +50°C

  • Humidity: up to 95% RH, non-condensing

Module Housing

Modules have housings that share plastic resin type and are molded with the same mechanical size dimensions:

  • Plastic Type: Eco Friendly ABS/PC

  • Plastic Flammability: UL94-5V

  • Enclosure Rating: IP20

  • Mechanical Size– Inches 3.6 W x 4.5 H x 2.5 D (Millimeters: 90 W x 114 H x 64 D)

Power Supply

A PS-24V power supply module is required for each Smoke Control Server. The PS-24V plugs into the model TB-PS-W1 DIN rail mounted terminal base. The right side of this terminal base directly mates with the TB-AS-W1 terminal base holding the Smoke Control Server. The PS-24V accepts input power from a 24 VAC transformer and consumes a maximum power of 60VA. The unit provides a 24 VDC (30W max.) output to the terminal base. This power is delivered to the Smoke Control and other modules positioned to the right of the PS-24V terminal base.

Power Supply Module

Power Supply Module

Optionally, you can add I/O modules to the right of the Smoke Control Server. These I/O modules consume 24 VDC power from the power supply module feeding the Smoke Control Server. When the accumulated power of the Smoke Control Server and I/O modules reach 30W, the output capacity from the initial power supply module is exhausted. If additional I/O is needed, you can connect another PS-24V power supply module on the right side of the last I/O module. This terminates the load on the previous PS-24V. You can now connect additional I/O modules to the right of the added power supply module which will supply them with 24 VDC power. You can repeat this process until a total of 32 modules are connected on the I/O bus (counting the Smoke Control Server, multiple PS-24V units and all I/O modules). Use the Power Budget table to determine when another power supply is needed. For more information, see Power Rating

For UL 864 systems, the DC power input rating (24 to 30 VDC @40W) is not applicable. Only the transformer-powered PS-24V has been evaluated using one of the approved transformers. For more information, see Transformers .

  • Power Input: 24 VAC (+-20%) 50/60hz

  • Recommended transformer rating: 60VA (or higher)

  • Maximum Input Current: 2.5A

  • Power Output: 24 VDC (+/-1V) 30W 1.25A

Smoke Control Server

The Automation Server (AS-SMK), or AS-P (AS-P-SMK) is the main controller in the smoke control system. The Automation Server and AS-P with the SMK suffix (AS-SMK and AS-P-SMK), refer to the UL 864 listed model which is the version you must apply in smoke control applications. As indicated previously, when the Automation Server (AS-SMK) and AS-P (AS-P-SMK) are discussed together, they will be referred to as Smoke Control Servers.

Note:

The Smoke Control Servers are the same standard model Automation Servers with the addition of the UL 864 listing mark, software revision restrictions, and a different installation instruction sheet.

The Smoke Control Servers are IP-Level CPU/controllers that communicate with the host WorkStations and other IP controllers and Ethernet devices using the 10/100 BASE-TX Ethernet interface. The Smoke Control Servers communicate with Continuum b3 Series and I/A MNB Series controllers using one or both of the RS-485 BACnet MS/TP interface channels.

The Smoke Control Servers communicate with the FSCS panel using either of the RS-485 channels with the selection of the Modbus protocol. The Smoke Control Servers also communicate with the variety of local I/O modules connected via a separate high speed RS-485 interface passing through the backplane terminal base units connecting all I/O modules to the Smoke Control Servers. The Smoke Control Servers plug into the model TB-AS-W1 terminal base which mounts/snaps onto a DIN rail.

The following table describes the ports provided on the Smoke Control Servers.

The Smoke Control Servers manage the communications from the Fire Alarm Panel (source of zone alarm signal input) and determine how that alarm signal is associated with the application program defined smoke zones in the system. The Smoke Control Servers managing the Fire Alarm Panel (FAP) typically assign the smoke zone number to the alarm signal and distribute that zone alarm signal to the other controllers responsible for taking action associated with the initial smoke zone alarm.

Typically, the zone alarm distribution will be from the Smoke Control Servers managing the FAP to the other Smoke Control Servers acting as Zone Managers. The Smoke Control Servers operating as Zone Managers will supervise and coordinate the operation of the BACnet MS/TP controllers connected to the two MS/TP network ports (COM-A and COM-B) provided on each Smoke Control Server.

The MS/TP controllers will typically provide the majority of direct control and monitoring of the field equipment used to create pressurized zone control. The Smoke Control Servers also support a large collection of I/O expansion modules locally connected in the same or adjacent enclosures. You can also define the I/O modules within Automation Server or AS-P programming to provide control and monitoring of smoke zone equipment. Due to the distributed nature of the HVAC system and the portion of that equipment participating in the smoke control system, the MS/TP controllers provide most of the equipment connections. The I/O modules may be more efficient when dealing with large AHU and damper clusters needing a large collection of I/O in a local area.

You can use the Smoke Control Servers in dedicated or non-dedicated smoke control applications and connect to the following components:

  • b3 BACnet controllers, such as b36xx-S, b38xx-S, and b39xx-S series

  • BACnet MNB controllers, such as MNB300, MNB-V1-2 and MNB-V2-2

  • FAP via Ethernet (BACnet/IP), or contact input from the FAP via digital inputs on I/O modules or MS/TP controllers

  • FSCS panel (using the RS-485 Modbus port)

Smoke Control System Functions

The Smoke Control Servers perform the following functions in a smoke control system:

  • Initialize and manage the smoke control system

  • Manage the normal mode HVAC comfort control

  • Receive fire alarms from the Fire Alarm Panel and instruct the BACnet devices to execute a smoke control strategy

  • Manage the FSCS display of equipment and alarm status and processes manual override direction from the FSCS panel

  • Manage weekly self-tests on dedicated equipment in the system

  • Supervise the Ethernet TCP/IP communications between the Smoke Control Servers

  • Monitor the controllers in the smoke control system and signal the FSCS when there is a communication fault or output override

Common I/O Module Features

The I/O modules include these common features:

  • Terminal base mounting

  • Hand/Off/Auto switches

Terminal Base Mounting

All I/O modules plug into the same model terminal base model TB-IO-W1 and spread their unique combination of inputs and outputs over the 24 wiring terminals provided on each base.

Hand/Off/Auto Switches

All I/O modules that provide analog or digital outputs include an optional Hand/Off Auto switch. The front panel of the I/O module with the -H model number suffix includes Hand/Off/Auto (HOA) switches that provide override control of the outputs. For Digital output types, the switch will accommodate the positions to select automatic operation (output driven by the Automation Server or AS-P), the override ON mode and the override OFF mode. For Analog output types, the switch will accommodate the positions to select automatic operation (output driven by the Automation Server or AS-P) and hand/manual override mode. When in the hand override position, a rotary potentiometer is provided to manually control the output voltage or current over the full range.

The Automation Server or AS-P reads the position of the HOA switch and enables the functional supervision required for UL864 compliance. While the HOA switches are useful during system installation and configuration, all switches associated with smoke control equipment must remain in the automatic position after system commissioning. All switches that affect smoke control equipment must be supervised by the Automation Server or AS-P and the status of the HOA switches reported to the Automation Server or AS-P managing the FSCS panel. If any HOA switches affecting smoke control equipment are detected in a position other than automatic, the Automation Server or AS-P must indicate a fault on the FSCS panel with visual and audible annunciation. You may use the common equipment fault LED as a visual indicator. However, a preferred scheme includes a separate LED indicator identified as an HOA Override Fault.

A summary of the I/O modules included in the smoke control system follows.
