Abstract

The invention relates to the signalling systems and is meant for signalling of the earthquake start. The device contains a housing, wherein there are placed, being electrically connected, a light signal source, a sound signal source, a timer, an electric switch and a support. The support is made in the form of a bell-crank, articulately fixed onto a horizontally placed, rigidly fixed into the housing axle, at the same time, one bell of the crank comes in contact with the switch, and onto the other bell there is executed a prominence with jack, wherein it is placed a ball. Under the ball it is placed a pick-off plate, rigidly fixed into the housing. According to the second variant one bell of the crank is made compound with the possibility of controlling its length.Claims: 3Fig.: 2
