Electrified Locks

The four basic types of Electrified Locks are

  • Magnetic Locks
  • Electric Strikes
  • Electric Panic Hardware
  • Electric Cylinder and Mortise Locks

There are two main, or common types of Electrified Locks, Fail Secure and Fail Safe. Fail Secure locks stay locked even when the power to them is shut off. If the power to Fail Safe locks is shut off, they will unlock.

Picture of a Magnetic LockThe Magnetic Lock may be the most common type of Electrified Lock. There are two types of Magnetic Locks, Shear Locks and Plate Locks, both are Fail Safe. A Shear Lock contains an
electromagnet placed within the top of the door frame, pointing down. A steal plate is placed in a recession at the top of the door. When the door is closed and the magnet is energized, the plate rises to meet the magnet and the door is locked. With Plate Locks, the steel plate is placed on the vertical surface of the door. The electromagnet is exposed vertically and it meets the steel plate as the door closes.

Picture of an Electric StrikeElectric Strikes are latch bars that can be operated remotely. They are used to replace conventional fixed strike faceplates in a door frame. Usually, the replacement in question involves a mortise lock or conventional mechanical cylinder that hooks into the latchbar of the Electric Strike. Electric Strikes usually have a angled or sloped surface which enables the latchbolt to lock into a keeper space within the Electric Strike pocket, behind the Electric Strike latchbar. When power for an Electric Strike plate is either shut on or off, the latchbar will release and allow the door to open without retracting the latchbolt. There are AC and DC versions of Electric Stikes, and they are available in both Fail Safe and Fail Secure options.

An electrified push bar on a door falls into the category of Electrified Panic Hardware. These electrified push bars can be locked or unlocked remotely. Many panic bars contain a request to exit switch, which is activated by the bar being pushed. There are two types of Electrified Panic Hardware, rim (surface) mounted (or Mortise Lock). The other type involves using vertical bars which fasten into strike pockets at either the top, bottom, or top and bottom of the door. Vertical bars are either concealed inside the door, or surface mounted.

Electrified Cylinder and Mortise Locks are essentially mechanical door locks with that come with an electric solenoid. The solenoid engages a small pin, which keeps the lock from opening. Electrified Cylinder Locks should only be used for light access control, since it only requires a little bit of force to break them. Electrified Mortise locks get their strength from the door they are fitted to. This means Electrified Mortise locks have the potential to be very strong. If needed, you can order Electrified Mortise locks that have an door position switch (dps). Other options for Electrified Mortise locks include an request to exit sensor and lock monitoring switch.
