Netvox R312A – Wireless LoRaWAN Emergency Push Button (Portable)

Netvox’s wireless portable emergency push button features a simple switch button that is activated when pressed. This device uses a tact switch that is easy to operate and easy to carry. When the emergency button switch is pressed, the alert signal is sent to a centralised monitoring system via the LoRaWAN protocol. “Safe” signals are also sent periodically to report range and battery status.
