What is wrong with mobile phone app alerting?

Well, not much! Our GroupAlarm App is a fast, inexpensive and reliable way of alerting your personnel. Combined with backup alert channels such as SMS or call, successful alert delivery is exceedingly secure. However, every system is only as strong as its weakest link – in that case, the smartphone itself. When it comes to smartphones, there are a couple of factors beyond your control as an administrator:

  • Cell reception can be spotty at times
  • Phone manufacturers operating system updates can be erratic / unpredictable
  • Dependency on mobile phone contract
  • Smartphones can run out of battery during a regular day

For these reasons, we collaborate with to deliver an alerting solution for the most demanding and sensitive applications.

FRED pager with GroupAlarm

You always have an overview of the status of each individual pager. All configurations are made in GroupAlarm, the pager no longer requires a programming station. The setup and installation of 50 pagers can be completed in 3-4 hours without any previous knowledge, and you can integrate the system directly into your processes.
