System Overview 2. System Overview 2.1 Definitions • Al_Com is the communication protocol for the AutroSafe Detection Loop. • AUTROLON is AutroSafe’s Local Operating Network. • AutroFieldBus is used to communicate with a BSD-340 interface and BSD-321. • PowerLoop is a two-wire bus capable of delivering 30VDC/ 100W connected in ring topology and is galvanically isolated from the rest of the system. The PowerLoop interfaces detectors and other loop units including a 4-20mA interface.
System Overview 2.2 System Example The illustration below depicts a system consisting of panels networked on an AUTROLON network. For compliance with C.E.N. regulations (EN-54), and for optimal safety, the AUTROLON must be installed as a ring loop. A maximum of 32 system units can be networked in this way. In the example, Al_Com communication is used to communicate with standard loop units and standard Ex-certified loop units.
IFG Functionality 3. IFG Functionality 3.1 Introduction This chapter covers some of the distinctions between AutroSafe functionality for Oil and Gas panels and standard AutroSafe panels. 3.2 Inhibit Point All loop input units can be inhibited. When one or several points are inhibited, the point(s) will not signal alarm to outputs. An inhibited point will however present an alarm, prealarm and early warning on all panels and AutroCom as usual. This includes panel buzzer, panel LEDs and panel LCD display.
IFG Functionality 3.5 Detection Zone faults and Point faults In standard AutroSafe, a point fault is presented as a detection zone (DZ) fault; the point in fault can be accessed via the panel menu. Oil and Gas panels can also be configured to present point faults as DZ faults. 3.
IFG Functionality 3.9 Support for Detectors Communicating on RS-485 (from SW 3.5.0) Release 3.5.0 (and future versions) supports the use of different detectors connected to the AutroFieldBus via the protocol-converter unit BSD-321. Supported detectors are: AutroPath, open-path gas detector SafeEye series 200/300, open-path gas detector AutroFlame CCTV flame detector and video switch Kidde Fenwal AnaLaser HSSD 3.
IFG Functionality 3.11 Local/External mode functionality Local/External functionality is selected via the AutroSafe configuration tool, as default, it is switched off (Local mode only). When switched on, the system toggles between the following modes: External mode: AutroSafe is operating together with an external system (with no communication faults or internal faults). The external system is able to control extinguishing agent activation.

System Hardware 4.8.3.5 Why loop-back? The BSD-321 requires a RS-485 loop-back connection. Loop-back is used to give increased system safety. While one channel on the BSD321 is transmitting, the other is receiving making it possible to verify that the internal operation of the BSD-321 is correct. By using RS-485 loop connection dual communication paths to the detectors are obtained in addition. Loop-back Loop-back of RS-485 can be done either locally on BSD-321 or remotely with loop to/from detector.
System Hardware 4.8.5 Typical applications using different signal references Application 1 The schematic drawing below shows an application where the reference is tied to the local earth. The cable shield is terminated at the BSD-321 end only.
System Hardware Application 2 The schematic drawing below shows an application where the reference is coupled to the detector’s reference. The RS-485 connection is floating at the BSD-321 side. The cable shield is terminated at the BSD-321 end only.
System Hardware Application 3 The schematic drawing below shows an application where the detector has common signal reference and Earth. The shield and signal reference is tied together at the same location by the detector only (the IE point at the ports are floating).
System Hardware 4.8.6 Port Isolation on RS-422 ports The schematic drawings show the RS-422 ports on the BSD-321. Each port is isolated from the rest of the electronics on the BSD-321 and has separate Instrument Earth per port. The signal reference of the driver / receiver is separated from Earth.

Projecting Guidelines 5.6 System Shielding and Earthing 5.6.1 Introduction The AutroSafe Integrated Fire and Gas System (IFG) has been designed to supply power and communications to advanced flame and gas detectors. The system is able to deliver up to 100W of power and uses a digital communications system, which modulates the PowerLoop at approximately 130kHz. The PowerLoop system also allows hundreds of metres of cable to be used between the loop driver and the field equipment.
Projecting Guidelines 5.6.3 Single Earth Systems – Power Loop Firstly, consider a Single Earth system for simplicity. 1) All PowerLoop cabling must be shielded Every segment of the PowerLoop cable has to be protected by a shield that effectively attenuates the radiated field from the cable. The shielding is required to avoid radiated emissions and hence crosstalk from one PowerLoop to any other. Armouring is normally not considered to be a sufficient shield.
Projecting Guidelines 4) Shield must be continuous The PowerLoop cable will be split in two segments, separated by field equipment including junction boxes or Loop Units. The shield must be continued through these separations. There must be no electrical connection to the local frame earth. In the following figure the junction boxes includes a strap / jumper to continue the shield between the cable segments (these straps / jumpers should be made of a suitable low-impedance cable).
Projecting Guidelines 5) Maximum cable length The PowerLoop Calculator will define the maximum length of each cable segment, this tool however determines length only from the power loss of the specified cable. The cable or wire capacitance will not affect the cable length as much as the resistive loss will restrict the power, not the communication. 5.6.4 Dual Earth Systems – Power Loop Some installations use both Instrument Earth (IE) and Protective Earth (PE) as two separate earthing paths.
Projecting Guidelines 5.6.5 Shielding & Earthing AutroFieldBus Each unit that may be connected to AutroFieldBus has described the local earthing requirements in their datasheet. In the total system overview, some key issues needs to be taken care of: • There are no absolute requirements for shielding, however if severe electromagnetic interference is expected, shielding should be applied. • If shielded cable is used, it should be continous. Care should be taken to avoid earth/shield loops.
Projecting Guidelines 5.6.6 Earth Fault Detection AutroFieldBus The enabling of the Earth Fault detection mechanism has been described earlier. It monitors the cable segment that is electrically connected to the EAU-341 loop driver. However, if the cable is interrupted electrically by a BSL-325 Booster or a Fibre modem, these segments may need additional Earth Fault Monitoring. This may be achieved by including a BSD-321 into this segment, and enable the Earth Fault Monitoring at this device.
PowerLoop Calculator Tool 6. PowerLoop Calculator Tool 6.1 Introduction The PowerLoop Calculator Tool is an integrated part of the AutroSafe Configuration Tool. The tool allows you to define and edit a Power Loop with a number of Loop Units. Based on the power consumption and the cable loss, the tool presents a go/no-go test to the user. The defined Power Loop can be saved for possible changes at a later stage.
PowerLoop Calculator Tool 6.2 Operating The PowerLoop Calculator Tool 6.2.1 Loop driver type Select first the PowerLoopDriver type (BSD-340 or BSD-340Ex) 6.2.2 Add Button • • • • Enter the cable length and cable dimension (the dimension is for your information only). Enter the specified resistive loss of the cable to be used. Select the detector type X33/1, BN-342 or Junction Box. If BN-342/EX is selected, also enter the actual load to the external equipment/detector (supplied by BN-342/EX).
PowerLoop Calculator Tool The Power In, Power Out and Cable Loss are calculated. Power In: Power supplied to the BSD-340, i. e. the total power consumption. Power Dissipation: To find out the total power/heat budget, the dissipated power from the BSD-340 inside the rack can be calculated. Simply calculate the power dissipation by Power In minus Power Out. Then add a comment in the Help about this field, to inform of the intention. Power Out: Power delivered to the loop from the BSD-340.
PowerLoop Calculator Tool 6.2.5 Delete Row Button • Select a row in the list box above to delete a row, then press Delete Row Button. When pressing the Delete Row Button, the tool automatically performs a new calculation and verification. 6.2.6 Load Config Button The Power Loop Calculator dialogue is modeless, thus it is possible to do configuration while the dialogue is open. In this way, the loop data (detectors in sequence) which is entered in the System View can be loaded.
PowerLoop Calculator Tool 6.2.8 Gra+phical Button This view shows only the loop units and the cable segments. If a (or several) Junction Box is included, this will not be shown in the graphical view. The cable segment will show only the closest cable information, causing this cable characteristics and resistance (to be observed in the view) not to be perfect. However the current flow and voltages at each loop unit will be calculated correct.
PowerLoop Calculator Tool 6.2.9 Ambient Temperature A maximum ambient temperature of the BSD-340 Loop Driver must be entered. The ambient temperature of the BSD-340 affects the maximum delivered power to the Power Loop. 6.2.10 Save and Load File The data entered from the user shall be saved to a file at request of the user, and same data may be read at a later stage for editing. All data in the current sheet will be lost if a file is read (make a warning).
PowerLoop Calculator Tool 6.2.11 American Wire Gauge (AWG) The conversion table puts into an exact relation the American Wire Gauge (AWG) number with the cross-section measured in mm2. The first column reports the AWG number, the second the corresponding diameter of the cable in mm, while the third reports the equivalent cross-section area in mm2. The table shows some examples of cables available, and their characteristics.
