The guard devices"Antej" have a function of multiple alarms suppress.
Permanent drawdown (false alarms) can occur due to a faulty sensor (detector) in the protection zone. This can lead to the monitoring desk equipment overload, an increase in response time to an alarm or malfunction of the desk. To avoid this, you can programmatically enable the multiple alarms suppress in Guard Panel. When you enable this mode, no more than three alarm reports for single guard session pass in each zone, subsequent alarms in the session are ignored.
