    Nittan Evolution EV-P Optical Detector With Optional Built In Sounder

    Using a simple but effective technique, the EV-P Optical Detector incorporates a chamber housing an Infra Red (IR) LED light and a photodiode light detector set at an obtuse angle preventing it from seeing the light. When smoke enters the chamber the light bounces off the smoke particles and strikes the photodiode, causing it to generate an alarm condition when a set threshold value is met. The EV-P Optical Detector is therefore more sensitive to larger smoke particles which tend to be caused by smoldering fires rather than fast flaming fires.

    Benefiting from the same sophisticated detection technology as the EV-P, the EV-PS Optical Detector comes with a sounder fully integrated within the sensor itself as opposed to a separate sounder base. The EV-PS sensor drives and controls the EV-PSBCN base, with the entire platform only taking one address for maximum system efficiency. This clever design makes for quick and simple installation, saving both time and money, whilst remaining extremely competitively priced. It also makes for a more aesthetically pleasing appearance, with a lower profile for an unobtrusive appearance.
