Also known as Security. This LED can only activate if there is a secondary device hooked into the Priority 2 Alarm terminals. This secondary device could be a security system, building management system, or another fire alarm control panel. Depending on how the panel is programmed, the panel's alarms may or may not activate when a condition like this is present.
Here, the westbound North American plate overrides the Pacific plate, creating the highly faulted and folded ranges from the Rockies to the Coast Mountains. Canada rides on one of 30 or so tectonic plates, or slabs, which underlie the earthâs continents and oceans.
Unique landforms are created at plates margins. There are four types of landforms created at plate margins: fold mountains, ocean trenches, composite volcanoes and shield volcanoes. Fold mountains are created at two types of plate boundary.1  At destructive boundaries: where an oceanic and a continental plate moving together.2  At collision boundaries: where two continental plates moving togther.hield volcanoes are found at constructive plate boundaries. As the two plates move apart magma rises up from the mantle. It then rises up through a vent forming a volcano. 1  Shield volcanoes have a wide base and gently sloping sides.
