Our aim is to develop an innovative visual and audible alarm device for fire alarmapplications with a CPD – EC Certificate of Conformity that meets EN 54-23. This Standardhas been introduced to ensure Visual Alarm Devices (VADs) are standardised in their lightoutput, ensuring there is a visual warning of an emergency situation. This ensures compliancewith the DDA and in areas of high ambient noise or where people have to wear ear defenders.The proposed visual and audible alarm will have the following benefits:• LED beacon that meets the optical performance required by EN54-23• Audible alarm with adjustable tone and voice messages that can be easily understood• Universal base plate containing LEDs with ‘click on’ modular fittings for conformitywith other manufacturers’ detection and alarm devices• Remote control for individual testing and setting of each alarm using wirelesstechnologyTo deliver the benefits the following enabling innovations have been identified:• LED and optical lens design will ensure maximum output to comply with EN 54-23with minimal power demand• Piezo-electric sound transducer reduces the power demand whilst have the rightfrequency response and sound pressure level for tone and voice; Tone, voice messages andvolume can be adjusted; device can be self-testing• Unique modular design allows ‘component building’ to suit client’s specification andbudget• New software protocols allow for universal integration of alarms with existingsensors/detectors and control panel boardsVisual and audible alarms are used extensively worldwide. All VADs for the Europeanmarket must comply with EN54-23 by July 2013; Cranford Controls who already have aportfolio of established products have recognised the opportunity to not only meet the newStandard but also to create a step change in visual and audible alarm technology. This willcreate new jobs within the UK, reduce client costs and substantially improve public safety.

我们的目标是开发一种创新的视觉和听觉报警设备，用于火灾报警应用，并获得符合EN 54-23的CPD - EC合格证书。本标准旨在确保视觉报警设备（VAD）的光输出标准化，确保紧急情况的视觉警告。这可确保符合《残疾歧视法》的规定，以及在环境噪音高或人们必须佩戴护耳器的地区。拟议的视觉和听觉警报器将具有以下优点：·符合EN 54 -23要求的光学性能的LED信标·具有可调音调和语音信息的声音警报，易于理解·通用基板包含LED，带有“点击”模块化配件，可与其他制造商的检测和警报设备保持一致·使用无线技术远程控制每个警报的单独测试和设置为了实现以下创新· LED和光学透镜的设计将确保最大的输出符合EN 54- 23的最小功率需求·压电声换能器降低了功率需求，同时具有合适的频率响应和音调和语音的声压级;音调，语音信息和音量可以调节;·独特的模块化设计允许“组件构建”以满足客户的规格和预算·新的软件协议允许报警与现有传感器的通用集成/探测器和控制面板视觉和听觉警报在世界范围内广泛使用。欧洲市场的所有VAD必须在2013年7月前符合EN 54 -23标准;已经拥有大量成熟产品的克兰福德控制公司已经认识到，不仅要满足新标准，而且要在视觉和听觉报警技术方面实现飞跃。这将在英国创造新的就业机会，降低客户成本，并大大改善公共安全。
