The JTW-BD-FCI-TD2000 intelligent temperature detector meets the national standard GB4716-2005 and is used to detect the heat generated by a fire and report the detected temperature analog quantity to the control panel. Due to the use of analog information, users, installers, and maintainers can obtain more information than regular systems. Meanwhile, as the probe is addressable, it can enable firefighters to quickly determine the location of a fire.
