Final answer:
Self-contained electromechanical locks combine electronic and mechanical components to provide secure access control. They operate independently and are commonly used in residential and commercial buildings. Examples include keypad locks and electromagnetic locks.
Step-by-step explanation:
Self-contained electromechanical locks are locks that combine electronic and mechanical components to provide secure access control. These locks are designed to operate independently and do not require an external power source or control panel. They are commonly used in applications where there is a need for both security and convenience, such as in residential and commercial buildings.
One example of a self-contained electromechanical lock is the keypad lock. It features a mechanical lock mechanism and an electronic keypad that allows users to enter a code to unlock the door. The lock's self-contained design eliminates the need for additional wiring or a separate control panel.
Another example is the electromagnetic lock. It utilizes an electromagnet and an armature plate to secure a door. When power is applied to the electromagnet, it creates a magnetic field that attracts the armature plate, effectively locking the door. In the event of a power failure, the lock is designed to fail-safe, automatically releasing the door to ensure emergency egress.
