Abstract: Devices, systems, and methods for alarm system states are described herein. In some examples, one or more embodiments include a mobile device comprising a memory and a processor to execute instructions stored in the memory to receive a notification from a remote computing device that an event device in an alarm system has detected an event, where in response to the alarm system detecting the event, the alarm system is in a conditional state, acknowledge the event to cause the alarm system to remain in the conditional state, and transmit a signal to the remote computing device indicating whether the event is a true event or a false event, the mobile device further including a user interface configured to display the notification.
