The single ultraviolet flame detector is a new type of intelligent fire detection equipment. Utilizing advanced ultraviolet detection technology, it employs a solar blind-band ultraviolet flame detector, effectively suppressing solar interference and achieving rapid response and accurate identification of flame signals. The detector employs non-contact detection, with sensitivity adjustable on-site, and provides passive contacts, standard current output, and connection to a fire alarm system.
