What Is Remote Monitoring of a Fire Alarm System?
DiTi Service engineers · updated 26.09.2026
Short answer
Remote monitoring sends the fire alarm's status to a dispatcher's computer over RS-485, Ethernet or GSM, showing which detectors are normal, where there is a fault and the battery charge.
The panel's status is sent to the computer of a dispatcher or maintenance company over RS-485, Ethernet or GSM. You can see which detectors are normal, where there is a fault and how charged the batteries are.
This is especially useful for unstaffed sites and for networks of sites in different districts.
Practical tips
Use GSM or Ethernet for remote sites and RS-485 within one building.
Set up notifications for faults, not just fires.
Test the communication channel at every service visit.
Frequently asked questions
Is a dedicated computer needed for monitoring?
Usually yes — a PC or server at the dispatcher's desk running monitoring software.
What happens if communication is lost?
The on-site system keeps working independently, and the dispatcher sees the lost link as a fault.
