Apollo 55000-137 Series 65 CS (90ºC) heat detector

  • A high-quality Type CS static/rate of rise heat detector.
  • Monitors temperature using a dual thermistor network which provides a voltage output proportional to the external air temperature.
  • Certified to EN54-5 by the LPCB.
  • Wide 9-33V DC operating voltage.
  • Red LED illuminates when the detector is in alarm.
  • Requires a BF308ZD diode base, BF308Z non-diode base or BF308ZR relay base.
