Visual and audible warning device

Newsteo WRN12, wireless warning device

The WRN 12 can communicate with any kind of Newsteo logger nearby. It will warn local staff in real time.
With its strong 80dB buzzer and its 40 lumen flashing light, WRN12 is the perfect complement of Newsteo smart wireless sensors to inform the local staff when a logger is on the alert. Once alarm is activated, a simple pressure on WRN12 red button stops the sound alarm. The red flashing light will go on until the logger will stop to be in alarm mode (or by software acknowledge).

  • Alert for exceeding the set thresholds
  • Real-time alert for people on site

  • Strong 80dB sound signal
  • Red light with an output of 40 Lumen
