Nittan EV-H-A1R 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.
