Fully-electric vibration sensor. This innovative Seismic sensor detects break-in attempts through prying, penetration, impact etc. using typical impact sound signals. Patented frequency analysis detects the difference between simple knocking, external vibrations and similar frequencies that typically occur during a break-in attempt. This guarantees unparalleled false alarm prevention. The sensitivity can be adjusted individually. The sensor is attached to the window frame, door frame or wall. The large recording range allows even extensive window elements to be monitored by a single sensor. Alarm memory LED. Sabotage monitored with NC cover switch. Recording range up to 4 m (radius)Maximum Current = 150 mAMaximum DC Voltage = 16VContact Resistance = 10OhmsLength = 85mmWidth = 25mmDepth = 23mmMinimum Operating Temperature = -20°CMaximum Operating Temperature = +60°CDimensions = 85 x 25 x 23 mm
