The Nittan EV-P Analogue Addressable Smoke Detector is specially designed for use with Nittan FSK protocol control panels. The design of the EV-P increases the reliability and performance of the detector.
The Nittan EV-P Optical Smoke Detector is connected by two terminals to the two wire loop. The remaining terminals provide an unlimited current (Terminal 2, Base Control) and a 3mA limited current (Terminal 3, RIL), when the detector goes into alarm condition. These currents can be used for the operation of an auxiliary function such as a remote indicator.
