A control unit (100) controls an alarm device (102) to give an alarm, if a room sensor (104) does not detect movement in an apartment (90) in a time period longer than a room delay, and if detections by a door sensor (106) and bed sensor (108) are missing during said room delay. The control unit (100) sets a predefined rest delay, which is longer than the room delay, if the bed sensor (108) has detected presence in a bed (114). During the rest delay, the control unit (100) does not control the alarm device (102) to give an alarm, even though the room sensor (104) does not detect movement for a longer time than the room delay. The control unit (100) shifts to the room delay or controls the alarm device (102) to give an alarm after the end of the rest delay, if it takes a longer time to detect movement in the apartment (90) than the room delay. When the door sensor (106) detects movement by the door (112), the control unit 100 starts, after the previous control delay has ended, a control delay that is shorter than the room delay, during which the control unit (100) does not control the alarm device (102) to give an alarm. After the control delay has lapsed, the control unit (100) is adapted at times outside of the rest delay to control the alarm device (102) to give an alarm, if the room sensor (104) does not detect movement in the apartment (90) during the control delay or the bed sensor (108) does not detect presence in the bed (114). The control unit (100) ends the control delay and starts the room delay, if movement is detected in the apartment (90) during the control delay without detection of movement by the door sensor (106) at times outside of the rest delay. After the control delay has lapsed, the control unit (100) controls the alarm device (102) to alarm during the rest delay, if the room sensor (104) has detected movement in the apartment (90) during the control delay without a detection by the door sensor (106). The control unit (100) ends the control delay, if the door sensor (106) has carried out a detection during a control delay within the rest delay. |
