Which mode will turn on all exterior and interior protection devices, while still allowing the exit and entrance delay times?

The mode that activates all exterior and interior protection devices while allowing for both exit and entrance delay times is referred to as "Away mode." In this mode, the system is fully armed, meaning that all sensors and alarms are operational to provide maximum security against intrusions when the premises are unoccupied.

The inclusion of exit and entrance delay times in this mode is crucial as it provides users the opportunity to exit the premises without triggering the alarm immediately and also allows them time to enter the building and disable the system. This is particularly important for situations where there might be a brief period of time needed to secure the area before the alarms are fully engaged.

In contrast, other modes such as "Stay mode" are designed more for situations where occupants are present but may want to allow for movement within the home while securing the exterior. "Sleep mode" typically provides partial protection and is used when individuals are in their sleeping areas, while "Home mode" reflects a state where certain sensors may be disarmed (especially interior motion sensors) to accommodate movement within the home. Thus, "Away mode" is specifically designed for complete security coverage when the property is vacant.
