The Turnip Entry sensor is the smallest full-featured security transmitter in the industry. It is typically used to sense opening and closings of doors and windows but can secure just about anything using its Strip & Stick external contact holes. It will alarm when the magnet is pulled away from the NanoMax or when the external contact is opened. 


Install by removing the adhesive paper and adhering the sensor and magnet on a door or window. Make sure to align the alignment marks on the NanoMax and magnet when mounting. 

3M™ VHB™ Tape works great if the surface is properly prepared and firm pressure is applied for over 10 seconds. Make sure to clean the surface before installing the sensors.

Wireless performance is optimized when mounted near the top of the door in a vertical orientation.
