Description of FDKU634-D-X

• The FDKU634-D-X is a Multi-Criteria Conventional Smoke Detector. This is certified with the UL268 7th Edition, which requires to pass flaming and smoldering polyurethane tests, as well as a nuisance test that detectors must not alarm when subjected to certain types of cooking smoke.
• In addition to the requirements of UL 268 7th Edition, this is also designed to distinguish smoke from dust with a unique chamber that prevents dust from entering the smoke detection area.
• The Nohmi’s new detection technology helps to reduce nuisance alarms and improve reliability of fire detection.
• This is applied with Nohmi’s new circuit integration technology. This state-of-the-art technology was able to simplify the product circuits and down-size the product structure significantly. The Nohmi’s extremely thin detectors do not spoil the aesthetics of the building. Its operates between 19.2 to 28.8VDC range (24VDC nominal) with compatible control units.
• This is set at a nominal sensitivity of 6.4% m (2.00%ft) smoke obscuration. If the detectors get dirty, the detectors should be replaced or cleaned the smoke chamber. The FDKU634-D-X has two LEDs that allow for 360° viewing.
• The FDKU634-D-X can notify the deviation of sensitivity by flashing the LEDs when smoke is detected. The detector is compatible with any of the Nohmi bases indicated in this sheet and simply twists on.
