The Nittan EV-DPH-A2R F14-82106 is a combined smoke & heat detector. The EV-DPH-A2R 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 EV-DPH can determine the particle size and thus distinguish between smoke and non-combustion products such as steam and dust. The EV-DPH-A2R is further enhanced by the addition of a Heat sensor with Class A2R, Rate or Rise performance. This provides an excellent solution to false alarms in areas prone to steam and dust, including hotels, hospitals and other areas of multiple occupancy.
