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.
