The Netvox R311A wireless door/window sensor monitors and reports the opening and closure of doors and windows by using a magnetic switch. The transmission signal is sent via the LoRaWAN protocol to your centralised monitoring system and can then be used to trigger an alarm system or simply keep track of when the sensors break contact.

• Compatible with the LoRaWAN protocol
• Requires 2 x CR2450 3v batteries
• Built-in antenna
• Simple operation and device configuration
• Reports battery voltage and window/door status
