Alarmtech VD 400 seismic detector

Alarmtech VD 400 is mounted on steel or concrete objects – safes, gun cabinets, concrete walls – and detects attacks with explosives and tools such as diamond drills, cutting wheels, grinders and thermal tools. Three independent detection channels and digital signal processing give reliable detection and high immunity to false alarms.

The detector must be mounted with firm surface contact and not across joints; on concrete and brick use the mounting plate with anchor bolt. For harsh indoor or outdoor conditions a heated housing is available. It has LED alarm indication and tamper protection.
