Product / service details

Principle of Operation
Netvox Wireless Door/Window Sensor is a magnetic contact sensor available to detect the state of doors and windows. R311A will transmit information and data to the server from the opening and closing of doors,
windows, gates, etc. based on the desired behavior. The low battery consumption device is long lasting
which ensures optimum usage.
Thanks to its small size, R311A can be installed everywhere. It is wireless so it takes up minimal floor
space. The transmission is directed to a central center that can be programmed to trigger an alarm
system. The versatile wireless sensor is reliable and suitable for various applications.
