What kind of electrical locks?
Electrical strike
They are door-locking devices, used in conjunction with various lock sets and access control systems to provide security and automatic door opening.
Electrical strike use a solenoid to control a movable keeper. Upon activation, the keeper allows the door to open even if the latch bolt is not is in the extended position.
Electric strikes prices vary from $30 to $400. Professional products must be compliant to certifications like BHMA or UL in the USA and ULC in Canada.
Electrified mortise
Electrified Mortise Locks are mortise locks with a solenoid that keeps the latch bolt from retracting (usually only from the unsecure side). As a result, it is only possible to turn a handle from the secure side to retract the latch bolt, then open the door. But impossible to turn it on the outside of the door, unless the solenoid is disengaged. Thus, anyone inside can get out simply by turning the handle. Outsiders must use a key or must have access granted by the access control system.
Similarly to electrical strikes, electrified mortise locks are available in either fail-safe or fail-secure modes.
Fail-safe and fail secure
In fail-safe mode, when applying power, the lock locks. Whereas in the fail-secure mode. When applying power, the lock unlocks. Thus, when power to the lock is disengaged or “fails”, the lock will go to its fail-safe (unlocked) or fail-secure (locked) mode.
An electromagnetic lock
It is an electromagnet attached to the top of the door frame and a metal plate mounted onto the door opposite the magnet. When the electromagnet is energized, the door is held closed with a force that varies from 500 to 1500 pounds.
Electromagnets are fail-safe equipment. They allow people out when there is no power. Because of fire evacuation, many cities have specific regulation of the electromagnet installation.
