The invention device seismic detector altitude relates to the field of seismology. Device altitude seismic detector converts weak seismic waves disturbing jerks in the sound and light signals. Device seismic detector altitude consisting of a rigidly mounted on the wall of the housing which is sensitive to seismic vibrations element and electrical warning circuit composed of a power source, tumbler, sounder, and the light emitter, characterized in that it is sensitive to seismic vibrations element consists of a microswitch with lever, the pendulum the rod and the load, a sphere, a circular plate, wherein the pendulum with the rod upper end with a counterbore simply supported on the needle, vertically mounted on a bracket fastening m on the body, is mounted at the lower end of the rod, the ball is set in the hole at the lower load end with a gap diameter, the center of the ball above the lower load end, the ball is able to freely roll on a flat, circular plate which is fixed on the lever of the microswitch, and also for fixing the bottom horizontal position simply supported on a stop lever with a plate has a free stroke between the stop and the end of the load from the position "on" to the position "off" in the absence of a sphere whose weight is greater than the restoring force of the spring microspots ereklyuchatelya with normally closed contacts. The device can be used in seismic areas to provide timely public notice of the initial stage of the earthquake, it can be installed in every room of high-rise buildings above the ninth floor. The device can be used in the system notification each entrance of a tall building from nine or more floors with the installation of audible alarm sounder on the stair aisles, and the device is set on the top floor with individual settings, given the natural oscillations of the building.
