Beschreibung
Zusammenfassung:	FIELD: intruder alarms for signaling about intrusion by perpetrators into guarded territory on basis of detection of characteristic mechanical oscillations of soil. ^ SUBSTANCE: device comprises one or a group of seismic receivers, installed in soil, which are joined by two-wire communication line with control panel. Seismic signal analyzer forms activation signal in case of appearance of perpetrators in seismic receiver detection zone. Transfer of information from seismic receivers to control panel and vice versa is realized by means of digital serial bidirectional receipt-transfer of information on basis of position-time code. ^ EFFECT: increased reliability of device due to ensured capacity for change of sensitivity of seismic receivers, provided addressed signal receipt mode from various seismic receivers and receipt of information for selection of moving objects on basis of mass. ^ 4 cl, 15 dwg
