将对ULC/ORD-C529A-13所述视频图像烟雾探测系统设备进行调查，目的是在摄像机限制范围内的视野区域内探测火灾烟雾图像。必须随产品的具体安装或操作参数一起描述产品。尽管视频图像烟雾探测系统设备可能包括火焰探测功能，但本ORD不包括火焰探测功能的测试或视频图像烟雾和火焰探测功能的组合。本ORD利用了ULC-S529《火灾报警系统烟雾探测器》中现有的适用“加拿大”要求，并纳入了评估视频图像烟雾探测系统设备所需的附加要求。 视频图像烟雾探测系统设备不打算直接替代标准的开放区域保护设备，但确实提供了传统设备无法实现的探测能力。对于整个系统，必须特别考虑视频图像烟雾探测系统设备？s的灵敏度和特别注意，以减少误报警的可能性。

The Video Image Smoke Detection Systems Devices addressed by ULC/ORD-C529A-13 are to be investigated with the intent to detect the image of smoke from a fire in the field of view area defined by the limits of the camera. Installation/operating document(s) and/or product marking information provided with the product must describe the specific operating parameters of the product.Although video image smoke detection system devices may include flame detection functions, this ORD does not include testing for flame detection functions or the combination of Video Image Smoke and Flame detection functions. This ORD utilizes the existing applicable "in Canada" requirements in ULC-S529, Smoke Detectors for Fire Alarm Systems, and incorporates additional requirements necessary for the evaluation of video image smoke detection system devices.The video image smoke detection system devices are not intended to be a direct replacement for standard open area protection devices, but do offer detection capabilities not possible with conventional devices. Special consideration must be given to the video image smoke detection system devices regarding the overall system?s sensitivity and special care taken to reduce the possibility of false alarms.
