Device for independently protecting against theft the goods transported in containers, trailers and lorries

摘要

The invention relates to a device making it possible to protect containers and goods transported, independently from the vehicles which tow or transport them. It consists of an alarm unit 1 placed inside the container and whose control parameters 8 and 13, placed on the outside, are circuit substitutions and the alarms 5, 12, 9, 17 made up of changes in state of the detection loops of the unit 1. The automatic protection operates permanently and is made up of an independent loop. Placing the encoding keyboard with an incorporated relay 7 and the lock with contacts 6 in series allows the device to be stopped only when possessing the code and the key. Any triggering simultaneously switches on acoustic warning devices 4, luminous warning devices 3, and radio warning devices 10.
