The Series 65A Ionisation Smoke Detector uses a low activity radioactive foil to detect fires by irradiating the air in the smoke chambers and causing a current flow. If smoke enters the chamber, the current flow is reduced leading to an alarm.

  • responds well to fast burning, flaming fires
  • designed to operate in a variety of enviroments
  • flashing LED and magnet operated test switch option
Approvals/certifications Certified to EN54-7 by the LPCB.
