Part No. F14-77010
Description
The EVA-DPH is an attractively-styled, low profile combined dual optic photoelectric smoke and heat detector for use with the Nittan NFU-7000 series of Fire Alarm Control panels. The EVA-DPH Dual Optical Detector goes one step further and uses both IR and blue LEDs to provide a more accurate measurement of particles within the chamber.
By calculating the ratio of these light sources, which operate at different wavelengths, the EVA-DPH can determine the particle size and thus distinguish between smoke and non-combustion products such as steam and dust. This patented, award winning technology is unique to Nittan and provides an excellent solution to false alarms in areas prone to steam and dust, including hotels, hospitals and other areas of multiple occupancy.
