Rate Of Rise Heat Detector

Nittan’s EV-H-A1R Analogue Addressable Heat Detectors are specially designed for use with Nittan FSK protocol control panels. Their special ASIC design increases the reliability and performance.
The Nittan EV-H-A1R Heat Detector is connected onto the two wire loop using two terminals. The remaining terminals provide an unlimited current (Terminal 2, Base Control) and a 2mA 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.
