Description of Nittan Smoke and Heat Detector EVA-DPH-UL Standard Nittan Addressable Fire Detector
The EVA-DPH is a low profile, attractive design that combines photoelectric smoke and heat detectors for use with the free alarm control panel of the NFU-7000 series.
The EVA-DPH dual optical detector goes a step further and uses both infrared and blue LEDs to provide a more accurate measurement of the particles in the chamber. By calculating the ratio of these light sources, operating at different wavelengths, EVA-DPH is able to determine the particle size and thus distinguish between smoke and non-combustible products such as steam and dust. . This patent, award-winning technology is unique to Nittan and provides an excellent solution for false alarms in areas prone to steam and dust, including hotels, hospitals and other areas. of many people.
EVA-DPH initiates alarms in response to both rapid acceleration and fxed heat (57°C) conditions. The thermal section incorporates a highly linear thermistor circuit, with the thermistor mounted externally. The special design protects the thermistor while allowing maximum air fl ow. The circuit thermistor generates a voltage proportional to the scaled temperature and digitally transmits the encoded value to the control board.
This EVA-DPH Nittan Heat and Smoke Detector has chemical etching, stainless steel insect screen thereby reducing insect penetration and airborne contaminants.
