The burglar alarm block can be used to easily set up an alarm system with the existing sensors (motion detectors, window contacts, etc.).
The alarm can be armed immediately or after a delay either via the block inputs or directly through the app.
If an Alarm is triggered, various alarm levels are started in a time-delayed manner.
An alarm can create alerts by flashing lights, playing an alarm sound/loud music, making phone calls, or raising the blinds and opening curtains.
Double click on the block to bring up the configuration menu, this allows selection of which sensors should trigger an alarm and which function blocks (lighting controllers etc) should be used as an alert.

|---|---|---|---|---|---|
| Rem | Remanence input | Remanence input: If active, the function block retains its previous state after a Miniserver reboot. The state of the function block is saved: – When saving to the Miniserver – At a planned reboot – Before a backup – Once per hour – When activating/deactivating an alarm system (max. every 10s) The data is saved on the SD card. |

Output on WDot↑
In case a window or door is still open when the alarm system is armed (delayed or normal), output (WDs) is activated and a message is output at (WDot). For example, "Attention, kitchen window is still open"! If several windows / doors are open, the output reads: "Attention! Several windows or doors are still open!".
Presence Sensor Functionality↑
When the alarm system is armed, Tree Presence Sensors connected to the alarm system are automatically set to the shortest overrun duration.
For battery-operated Presence Sensor Air, the overrun time can only be adjusted during the next status update from the sensor. These sensors do not support immediate changes to the overrun time.
If the alarm is armed while the Presence Sensor still detects presence, the active motion will immediately trigger the alarm. Therefore, to prevent false alarms, it is crucial to arm the system with a delay.
Arming the Alarm: Without Delay vs. With Delay↑
When the alarm system is armed, the overrun time for Presence Sensors (Tree) is automatically set to the shortest duration. However, the alarm may be triggered immediately if the Presence Sensor's input is still active. The input will deactivate after 3 seconds of no motion detection. This delay might be too long for the burglar alarm system, potentially triggering a false alarm.
Arming Without Delay
Arming the system without a delay is appropriate only when you are confident that no one is inside the building. For instance, if you leave home and forget to set the system with a delay, you can activate it immediately once the house is confirmed empty, ensuring that no movement will trigger the alarm.
Arming With Delay
If there is a chance that motion could still be detected, it is advisable to set the system to activate after a delay. The delay duration can be modified to fit your requirements, providing sufficient time to exit without inadvertently setting off the alarm.
