BS EN 50131 2 4 specifies for combined passive infrared and microwave detectors installed in buildings and provides for security grades 1 to 4, specific or non specific wired or wire free detectors, and uses environmental classes I to IV. For a combined detector where both detection technologies need to be in their activated state in order to generate an alarm condition, the grade dependent requirements of BS EN 50131 2
