Nittan Evolution Heat Detector

Unlike smoke detectors that detect the presence of smoke particles, heat detectors only react to changes in temperature. The EV-H-A1R is a Thermistor based Heat Detector, which use electronic components that change their resistance when heated; this change is detected by circuitry within the detector.

Key Features

  • Option Of A1R (54°C) or CS (92°C) Classification Heat Detector.
  • Evolution FSK protocol.
  • EEPROM Addressed (Programmer).
  • RIL and Base Control Outputs.
