What is alarm monitoring?
A monitored alarm offers additional security and peace of mind over a traditional non monitored alarm. Once your alarm has been activated, your system will send a signal from the main control panel to our 24 hour alarm monitoring control centre. When the signal is received, we will immediately verify that the alarm is genuine before notifying your keyholders and the emergency services.
