Application
The HF-24 ultraviolet fire detector is suitable for use in automatic fire alarm systems in places where the fire is likely to break out quickly or where valuable assets are stored such as: Petroleum storage, engine room. Computer, Library, Museum. The HF-24 ultraviolet fire detector is not a replacement for smoke or heat detectors, it should only be used to increase protection against rapidly spreading fires. Here, there are no regulations on the protection area for ultraviolet detectors. The reason is because any fire any distance will affect the detector. However, a very small fire would take 7-15 seconds at less than 12 feet to ignite and 20-30 seconds at 25 feet.
Working principle:
The HF-24 detector uses an ultraviolet sensor that will absorb extremely weak sources of ultraviolet light, like the kind emitted by a flame. The sensor will return a series of pulses forming the fill current. And the electronic circuits in the detector will convert this current an alarm signal. Here there will be an electrical circuit that recognizes strong and unwavering sources of ultraviolet light such as the light of lightning and lightning. In addition, there is a filter circuit in the detector to limit the wavelength of the light sensor to between 1850 and 3000 angstroms to limit visible light and infrared light.
Basic function: Fast fire sensor
High reliability, long life UV sensor Low current consumption
The HF-24 detector can be combined with other detectors on the same zone circuit of the central cabinet.
Can be used with the same base as Hochiki . heat and smoke detectors Same size and color as Hochiki . heat and smoke detectors Easy to maintain
– clean without having to disassemble
– assemble the detector Not UL compliant
