MS-2. MS-2 is a two zone conventional fire alarm control panel compatible with the new I3 smoke detectors from System Sensor, and provides such advanced features as drift compensation, maintenance alert, and freeze warning.
The Ring of Fire describes the margins of the Pacific Plate, which is ringed by volcanoes and experiences frequent catastrophic earthquakes, from New Zealand to Indonesia to Japan and Russia's Kamchatka, through Alaska's southern fringe along the entire western coast of the Americas.
The most volcanically active belt on Earth is known as the Ring of Fire, a region of subduction zone volcanism surrounding the Pacific Ocean. Subduction zone volcanism occurs where two plates are converging on one another. One plate containing oceanic lithosphere descends beneath the adjacent plate, thus consuming the oceanic lithosphere into the earth's mantle. This on-going process is called subduction. As the descending plate bends downward at the surface, it creates a large linear depression called an oceanic trench. These trenches are the deepest topographic features on the earth's surface.
