// Alarms

Your plant's alarms
on WhatsApp.

Text, voice, charts and acknowledgement on the on-call person's phone, even with a voice message. The plant only needs a data SIM: no dialer, no phone line.

How it works

  1. The plant. The PLC raises the alarm; the 4G router with a data-only SIM sends it to the server.
  2. The server, in the European Union. It recognises the alarm, picks the on-call staff and checks that the plant is always online.
  3. WhatsApp. The message arrives with the alarm and a voice note that reads it out loud.
  4. The on-call person. Taps «Take charge», asks for values or a chart, even with a voice message.

If nobody answers

If the alarm is not taken in charge within a few minutes, the on-call chain starts: reminder, second on-call person and then a voice call. Timing, order and night hours are agreed with the customer. Every voice message is kept in the plant log, with name and time.
