An intelligent door lock system includes a position sensing device configured to be coupled to a drive shaft of a lock device. The position sensing device senses position of the drive shaft to assist in locking and unlocking a lock of a lock device. A processor is coupled to a wireless communication module that utilizes audio and RF communication to communicate. Audio is used to communicate a security key to the wireless communication device and the RF increases a wireless communication range to and from the wireless communication device. A circuit is coupled to the engine and to an energy source. A device converts energy into mechanical energy and is coupled to the circuit, positioning sensing device and the drive shaft. The device that converts energy is coupled to the energy source to receive energy from the energy source.

A security device is provided including a security lock configured to retain an object when locked, a receiver configured to receive a security code transmission, and processing circuitry configured to transition the security lock between a locked state and unlock permissive state based on receipt of a security code. The security lock may initially be set to the unlock permissive state. At the first instance in which a security code is received, the processing circuitry may transition the security lock to a key permissive mode in which the security lock transitions to a locked state and in response to a subsequent receipt of the security code the security lock transitions to the unlock permissive state.

An intelligent door lock system is retrofitted to an existing door lock system that includes a door lock system with a lock and a drive shaft; and an intelligent door lock system. The intelligent door lock system includes, a position sensing device configured to be coupled to a drive shaft of a lock device, where the position sensing device senses position of the drive shaft to assist in locking and unlocking a lock of a lock device, an engine with a memory, with the engine coupled to the positioning sensing device, a circuit coupled to the engine, an energy source coupled to the circuit, and a device that converts energy into mechanical energy coupled to the circuit, positioning sensing device and the drive shaft, the device that converts energy being coupled to the energy source to receive energy from the energy source.

A delayed unlocking push-down type emergency door-locking device includes a main lock seat, a secondary lock seat, a push-down type handle assembly, a position-sensing module and a timing electromagnetic traction assembly. The push-down type handle assembly is configured for moving along a driving path from a locking position toward an unlocking position, thereby at least one of locking element of the main lock seat is separated from a locking groove to unlock. A stopper is disposed at the secondary lock seat, configured for moving between a stop position and an avoidance position. The timing electromagnetic traction assembly is configured for counting time upon when the position-sensing module detects the push-down type handle assembly is separated from the locking position, and for pulling the stopper from the stop position to the avoidance position after delaying a predetermined delay time to the unlocking position for delaying.

A building alarm system and automated door lock arranged to place the alarm system in an armed state when a door lock fails to engage to lock an associated door in a closed position. Activation of a single button by a user or use of specific code by a user to gain access to a building can cause the alarm system to automatically rearm and for door locks at the building to be locked after entry by the user. A first responder code can be used by first responder personnel to gain access to a building after an alarm system indicates an alarm state, e.g., that corresponds to an emergency condition.
