Techko's S081H Magnetic and Vibration Sensor Entry Alarm can provide valuable protection for your home or property by detecting the unauthorized opening of a door, sliding window or cabinet door or by the vibration or breakage of a glass window. This combo-unit can be mounted on any door or glass window and requires no wiring or special installation. When the door or window is opened or if the alarm detects glass vibration or breakage, the alarm's switch detector sounds the built-in 65/90 db alarm. After 60 seconds, the alarm will reset itself. To arm or disarm the system, there is a convenient slide switch on the side of the unit.
