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用于火灾报警应用的创新型视觉和声音报警设备，并获得符合 EN 54-23 的 CPD – EC 合格证书。该标准的推出是为了确保视觉报警设备 (VAD) 的光输出实现标准化。是紧急情况下的视觉警告，这可确保遵守 DDA 以及在环境噪音较高或人们必须佩戴护耳器的区域。建议的视觉和听觉警报将具有以下内容。优点：• 满足 EN54-23 要求的光学性能的 LED 信标• 具有可调节音调和易于理解的语音消息的声音警报• 包含 LED 的通用基板，带有“点击”模块化配件，可与其他制造商的检测和警报保持一致设备• 使用无线技术对每个警报进行单独测试和设置的远程控制为了提供以下优势，已确定了以下支持创新：• LED 和光学透镜设计将确保最大输出，以符合 EN 54-23 标准，且功耗需求最低•压电声音传感器降低了功率需求，同时具有正确的音调和语音频率响应和声压级；音调、语音消息和音量可以自我测试。独特的模块化设计允许“组件构建”；适合客户的规格和预算• 新的软件协议允许警报器与现有传感器/探测器和控制面板的通用集成视觉和声音警报器在全球范围内使用所有欧洲市场的VAD 都必须符合。 EN54-23 已于 2013 年 7 月通过；Cranford Controls 已经拥有一系列成熟产品，他们认识到不仅可以满足新标准，而且可以在视觉和声音报警技术方面实现重大变革，这将在英国创造新的就业机会，减少就业机会。客户成本并显着改善公共安全。
