Your alarm when triggered will make a deafening sound for around 10 minutes.
Most popular option with the Bosch system is notification via the Bosch app – this means the alarm notifies you via the app when triggered. This option requires a cable to be connected from the Alarm Panel to the modem.
You may choose to call your neighbour or family / friends to check up on your property.
If you choose to add Back to base monitoring, then an alarm monitoring centre will call your mobiles to let you know. They may then send out a security car to check up on the property for a fee.
