PA/V A SOLUTIONSVARIODYN D1Digital Public Address andVoice Alarm System2 | Voice Alarm is increasingly important in the safe management of buildings. A voice message informs occupants exactly what to do in an emergency and it is a long established fact that people respond more quickly and are more likely to take the correct action during an evacuation if voice messages are used instead of tone sounders.THE ROLE OF VOICE ALARM• Clear directions to people in the building• Live messages giving exactinstructions to people whoare not familiar with the surroundings • Customised pre-recordedmessages (available inmultiple languages)• Up to 20 minutes shorter response time to fire alarm• Serial Interface toHoneywell fire panels for EVAC guidance and time-controlled evacuation • High-end non-emergency features such asequalizing, automatic volume control and multi-channel announcements as well as backgroundmusic • Alarm cancellation and manual evacuation override controlBENEFITS | 3PUBLIC ADDRESS -MORE THAN VOICE ALARMVoice Alarm systems are more frequently used as public address and entertainment systems than only as automatic evacuation system inpublic buildings with a high number of visitors.• Paging and evacuation with zone-dependent messages • Integration with airport/train station managementsystems• Multiple channel/zone music broadcasting • Sport/concert hall and stadium sound systemintegration • Time-scheduled announcements• Touch screen operation panels• Operation from intuitive computer management systems • High quality background music for high class shopping experienceFEATURES PUBLIC ADDRESS PROVIDES ADDITIONALL Y:4 |Selecting, designing and commissioning a PA/VA system can be challenging. At Honeywell we have a team of experts that will help you build the most suitable system for your building.The first step is to decide exactly what type of PA/VA system you will need. This will largely depend on the size and functional complexity of your building.The following two types of systems are available that start from small ‘Compact Solution’ packages suitable for single storey buildings such as shops and offices and move up to a custommade ‘Modular System’ that will consist of a number of distributed systems linked together for large structures such as exhibition fairgrounds and airports.VOICE ALARMCOMPETENCE FOR YOU• Controlling and indicating equipment certified to EN 54-16 and EN 54-4• Complete range of EN 54-24 certified loudspeakers • Flexible systems that supports both simple and the most complex communication needs • High quality digital audio matrix• Intuitive touchscreen Graphical User Interface that manages the entire system • Phased evacuation scenarios • Situation, location & evacuation phasedependent voice messages • Exact guidance regarding evacuation routes• Freely configurableevacuation scenarios with logical dependencies • Dedicated Honeywelldesign and project supportSYSTEMS KEY FEATURES |5 LEISURE COMPLEXES SCHOOLS SMALL HOTELS OFFICESTHE COMPACT SOLUTION:COMPRIO D1An easy-to-install PA/VA system.Suitable for small to medium buildingswith up to 24 loudspeaker zones.APPLICATIONS• Leisure complexes• Supermarkets• Schools• Hotels• OfficesBENEFITS• Amplifier with build-in PSU available• ‘Off the Shelf’ Package• Installation within two hours• Only 8 HU rack space incl. amplifier,charger and batteries• Ensured compliance to ENstandards• Complete solution for up to 24zones• max. 2000 W output powerexpandable with additional DOM/AMPs6 | Our PA/VA systems can be distributed and networked together to deliver the most comprehensive and powerful solution for a wide range of applications. Suitable for mid to large and complex sites.THE MODULAR SOLUTION V ARIODYN D1• Industrial facilities • Universities• Airports and transport hubs • Stadiums• Exhibition halls and fairgrounds • Mega Shopping Malls • Large Office buildingsAPPLICATIONS• Scalable and modular to adapt to constant changes and demands• Supports a large number of evacuation and/or paging zones • Manages complicated evacuation strategies in the event of an emergency • IP connectivity tolink multiple nodes (VARIODYN D1 DOM)BENEFITS• Up to 120 announcements at the same time• Pre-recording and playbackof messages• Secured data link to various Honeywell Fire Alarm Systems• Decentralized and redundant system architecture• Interface to BuildingManagement Systems (e.g. Honeywell EBI)• Redundant network and Call Stations linksComputer Management Station (PAMMI)Decentralized | 7STADIUMS AIRPORTS SHOPPING MALLS RAILWAY STATIONSCUSTOMISED CONTROLThe PAMMI (Public Announcement Man Machine Interface) software provides monitoring and control of the Honeywell Voice Alarm System via a graphical user interface on a Microsoft Windows® based personal computer.PERFECT SYMBIOSIS VOICE ALARM AND FIRE ALARMAREA BY AREA, TARGETED AND ORDERL Y:EVACUATION PROCEDURE EXAMPLE AT THE AIRPORT• There is a short-circuit in the baggage sortingarea on the 1st sub-level,section B of the airport. • The fire detector detects the formation of smokeand transmits theinformation to the firealarm control panel.• The fire alarm system simultaneously initiatesalarms to the securityservices and the voicealarm system.• The security inspectorassesses the situation viathe video camera installedon-site and then activatesa stored a nnouncementto the personnel with thepush of a button.• Due to the increasingformation of smoke,the fire alarm systemautomatically closes thefire door in the affectedarea.Synergies arise through digital coupling of the fire alarm system with the voice alarm system, thus facilitating an orderly, area-specific evacuation during emergencies: If a fire is detected by the connected fire detectors and then received by the fire alarm control panel, this automatically activates the voice alarm system. The endangered areas are then selected automatically and informed via the PA/VA system, while at the same time the fire alarm control panel activates fire protection systems, for example, fire doors, air-conditioning and ventilating systems, elevator controls or smoke dampers.The combination of voice alarm and fire alarm technology not only offers functional advantages, there are economical advantages as well: PA/VA reduces the total EVAC time significantly, a PA/VA system is not much more expensive than standard sounders, while it adds valuable support by increasing productivity of building occupants.8 | | 9VARIODYN D1 AND COMPRIO PA/VA SYSTEM DIAGRAM Thanks to its modular construction and the varioussystem components, the VARIODYN D1 system can easily DCS Digital Call Station DSCF DSC for Firefighter Fire Alarm Control PanelInterfaceDOMAMP PSUDCSF 1/12Configuration via LaptopCD playerETCSDCS PlusCentral Operating Terminal(PAMMI, WINMAG, Honeywell EBI etc)Loop Isolator ModuleAdvanced,Automatic Volume Control10 | WINMAGPLUSONE MANAGEMENT SYSTEM FOR ALLPERFORMANCE FEATURES OF THE VARIODYN D1 INTERFACE WINMAGPLUS DRIVER• System configuration readout of a VARIODYN D1 network to take it over via import files to WINMAGplus application.• Fault and status indication of the VARIODYN D1 system components: • DOM, SCU, DAL bus devices like DCS and • UIM, Amplifiers (each channel)• Audio and control contact inputs and outputsThe WINMAGplus hazard management system lets you create a scalable software solution with superb levels of integration with different sub-systems.In case of Voice Alarm system, VARIODYN D1 is connected via Ethernet/RJ45 to the same network as the WINMAGplus server.

Simplified, prescriptive method, requiring loudspeakers mounted every 6 meters or less.2. Detailed method, requiring in practice acoustics simulations as VA system design base regarding spacing, location, type selection, audio equalizing and proper orientation of loudspeakers.Acoustic simulations are paramount for a proper PA/VA system design in complex, tough and large areas. EN 50489 and CEN/TS 54-32 require minimum intelligibility level from installed VA systems. Installing and planning VA systems bears a risk of failure during intelligibily measurements in the handover phase. Toprevent such critical situations and underbudgeting of VA systems acoustic simulations are the only guarantee. |13EXAMPLE OF THE ACOUSTIC SIMULATION OF AN AUDITORIUM Acoustic simulation software provides to precisely and reliably assess sound pressure level (dB) and intelligibility level (STI/CIS). The software calculates the simulatedroom as a space map in 3D, enabling the user to verify the selected type, location and setting of loudspeakers.Voice Alarm system design for acoustically challenging areas must be based on professional, quality simulations,prepared by experienced acoustic experts.Our Technical Support Team provides expertise, experience, tools and wide portfolio of certified VA loudspeakers to assure our partners and system designers that Variodyn D1 system designs will pass acceptance tests.14 | VARIODYN D1 PRODUCT FAMIL YAll of the components of the VARIODYN D1 product family are compatible, interchangeable and optimally adapted to the customers growing needs.

压电变压器直流高压电源设计摘要压电陶瓷变压器是一种新型的压电换能器件,具有尺寸小,结构简单,不可燃,耐辐射,高可靠等优点。
压电变压器在电视显像管、雷达显示管、静电复印机、静电除尘、小功率激光管、离子发生器、高压极化等设备中得到广泛的应用。
本课题是研究压电变压器设计出10kV的直流高压电源。
当在压电陶瓷变压器输入端(驱动部份)加入交变电压时,通过逆压电效应,瓷片产生沿长度方向的伸缩振动,将输入电能转变为机械能;而发电部分则通过正压电效应将机械能转换为电能从而输出电压因瓷片的长度远大于厚度,故输出端阻抗远大于输入端阻抗,输出端电压远大于输入端电压.一般输入几伏到几十伏的交变电压,可以获得几千伏以上的高压输出.关键词:压电陶瓷变压器直流高压阻抗Design of Piezoelectric Transformer DChigh voltage power supply ABSTRACTPiezoelectric ceramic transformer is a new type of piezoelectric transducer device, the size is small, simple structure, non-combustible, resistance to radiation, high reliability.
