Standard for Video Image Smoke Detection System (VISD) Devices
Scope:
These devices 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 standard would not include testing for flame detection functions or the combination of Video Image Smoke and Flame detection functions. This standard would utilize 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.
