Nittan EV-H-A1R Heat Detector Analogue Addressable Rate of Rise EV-H-A1R Nittan

Description

Nittan EV-H-A1R Evolution Heat Detector Analogue Addressable Rate of Rise Nittan EV-H-A1R Heat Detector Analogue Addressable Heat of Rise Features: 54°C heat detector Sensing element: thermistor Using Nittan Evolution FSK Protocol EEPROM addressed Low profile Operational voltage range from 20V to 35V Low monitoring current Omniview 360° LED (fire alarm indicator) Remote indicator output Base Control auxiliary output Non-polarised terminal Standard EN54-5:2000 + A1:2002  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.
