An internal detector with dual technology detection utilising a combination of PIR and microwave sensors, for use in domestic and commercial installations. These grade 2 detectors use a combination of PIR and microwave detection technology to provide greater tolerances to changing environmental conditions. Available in both wired and radio variants, these detectors link seamlessly into the Eaton security system in terms of function, style and reliability. Pet tolerant variants are also available in wired and radio from. The use of standard AA batteries for the radio variant reduces service complexity while maintaining typical
battery life of two years.
