Although "listed" video image smoke/flame detectors are available, it is still the norm for these cameras to be used as supplemental protection. That is, they are not commonly installed for code compliance-yet. VISD systems, software and equipment have been UL Listed under URXG which is called "Smoke Detectors for Special Applications" to comply with UL Standard 268. The FM listing is under "Initiating Devices-Flame Activated or Initiating Devices-Smoke Activated," to comply with FM Standard 3232.
It's just a matter of time before we will be employing this new technology in code applications. This modern image of smoke detection will soon be an important part of the landscape of fire protection in the future.
