Classification of Electrified Locking Devices
by SDC
Classification and Glossary of ELECTRIFIED LOCKING DEVICES
Architectural Hardware: Term applied to all hardware used in a building construction, but particularly that used on or in connection with doors, windows, cabinets and other movable members. Also known as Builders Hardware and more specifically, Door Hardware (See DHI Glossary of Terms).
Electrified Architectural Hardware: Electrically operated products associated with doors, windows and cabinets. Also known as Electrified Builders Hardware (See DHI Glossary, DHI Tech Talk EA1/91). This includes all electric door hardware including electric door openers/closers, electrified locking devices, exit devices, door holders, etc.
Electrified Locking Devices: An electrically powered device, which enables a door to be locked or unlocked in response to an electric signal from an input or controlling device (See ANSI/BHMA Standards). Also known as Access Hardware and Access Control Hardware.
CLASSIFICATION OF ELECTRIFIED LOCKING DEVICES
The following is a list of electrified locking devices segregated into different product classes according to design and operational attributes. Items marked with an asterisk (*) are manufactured by SDC.
CATEGORY: ELECTROMAGNETIC LOCKING DEVICES
CLASS: Electromagnetic Lock (aka, Magnetic Lock, Maglock)
DESIGN & OPERATIONAL ATTRIBUTES: An electromagnet normally mounted to the frame that when powered is magnetically coupled to a door mounted armature, locking the door without the assistance of any mechanical interaction between the magnet and the armature assembly.
1. *Surface Mount Electromagnetic Lock
2. *Surface Mount Electromagnetic Gate Lock
3. *Mortise Mount Electromagnetic Lock
4. *Electromagnetic Delayed Egress Lock
ANSI/BHMA DEFINITIONS & DHI GLOSSARY
ELECTROMAGNETIC LOCK – An electrically powered lock that locks or unlocks a door by the activation or deactivation of an electromagnet that is magnetically coupled to an armature (sometimes referred to as strike).
DELAYED EGRESS LOCK – A delayed egress lock is a device or combination of devices arranged to be locked in the direction of egress for a predetermined time after the releasing process has been initiated. After the predetermined time, the door operates normally.
ARMATURE: A piece of iron or steel that connects the poles of a magnet (sometimes referred to as strike).
CLASS: Electromagnetic Shear Lock (aka. Magnetic Shear Lock)
DESIGN & OPERATIONAL ATTRIBUTES: An electromagnetic shear lock normally mounted in the mortise of a frame that when powered is coupled to a door mounted armature by both magnetic force and the interaction between movable or fixed interconnecting mechanical stops.
1. *Mortise Electromagnetic Shear Lock (aka, Concealed Magnetic Shear Lock)
2. *Semi-Mortise Electromagnetic Shear Lock (aka, Semi-Concealed Magnetic Shear Lock)
3. *Surface Mount Electromagnetic Shear Lock
GLOSSARY
SEMI-MORTISE - A frame mounted lock with a surface mounted armature or strike assembly attached to the door.
CATEGORY: ELECTROMECHANICAL LOCKING DEVICES
CLASS: Electrified Lockset
DESIGN & OPERATIONAL ATTRIBUTES: Latch or latch and bolt assembly with key cylinder and knobs or lever handles for manual operation and is equipped with a solenoid or motor for electrically controlled locking and unlocking.
1. *Electrified Mortise Locksets
2. *Electric Frame Actuator Controlled Mortise Lockset (no electric hinge or wires through the door required)
3. *Electrified Cylindrical Locksets
4. *Stand Alone Mortise Locksets; card, keypad or biometric actuated; battery powered or hardwired
(Aka integrated lock).
5. *Stand Alone Cylindrical Locksets; card, keypad or biometric actuated; battery powered or hardwired
(Aka integrated lock).
ANSI/BHMA & DHI GLOSSARY
LOCKSETS – A lock, complete with trim, such as knobs, escutcheons or handles.
MORTISE – A cavity made to receive a lock or other hardware.
CYLINDRICAL (LOCKS & LATCHES) – A term used to describe bored locks, which have a cylindrical case into which a separate latch bolt case fits.
FRAME ACTUATOR – A frame mounted mechanism, which manipulates a component of a cooperating locking mechanism in a door in response to signals from an input or controlling device.
CLASS: Electrified Exit Device
DESIGN & OPERATIONAL ATTRIBUTES: A door latching assembly incorporating an actuating member usually called an actuating bar which releases the latch bolt(s) upon application of force in the direction of exit travel or by activation of an internally mounted solenoid or motor.
1. Electrified Mortise Exit Device
2. *Electric Frame Actuator Controlled Mortise Exit Device
3. Electric Latch Retraction Rim Mount Exit Device
4. Electric Latch Retraction Vertical Rod Exit Device (Surface Or Concealed)
5. *Delayed Egress Exit Device (Mortise Lock, Rim And Vertical Rod)
ANSI/BHMA & DHI GLOSSARY
EXIT DEVICE – A door-locking device designed to grant instant exit by pressing on a cross bar that releases the lock bolt or latch.
Mortise Exit Device – An exit device with a lock mechanism installed into a mortise provided in the edge of the door.
RIM EXIT DEVICE– An exit device with latching mechanism applied to the face of the door.
VERTICAL ROD EXIT DEVICE – A device with top and bottom latching mechanism applied to the face of the door or concealed inside the door and connected by rods to the actuating mechanism. Vertical rod assemblies may be equipped with top and bottom latching mechanisms or top latching mechanism only.
FRAME ACTUATOR – A frame mounted mechanism, which manipulates a component of a cooperating locking mechanism in a door in response to signals from an input or controlling device.
CLASS: Exit Control Locks and Exit Devices
DESIGN & OPERATIONAL ATTRIBUTES: A rim mounted paddle device or rim mounted exit device, which releases the latch, or latch and bolt, and sounds an alarm upon application of force in the direction of exit travel. Alarm may be powered by a battery or low voltage power supply. There is no internally mounted solenoid or motor for remote access control.
1. Exit Control Lock
2. Alarmed Exit Device
CLASS: Electric Strike (aka, Electric Door Opener, Electric Door Release)
DESIGN & OPERATIONAL ATTRIBUTES: An electromechanical device used in place of a standard strike, equipped with a solenoid or motor for electrically controlling a movable keeper for the purpose of allowing a latched and locked door to be opened by push or pull without manual lock operation.
1. *Electric Strike
2. *Rim Mount Electric Strike (for use with rim mount exit device)
DHI GLOSSARY
STRIKE – A metal plate or box that is pierced or recessed to receive the bolt or latch when projected.
RIM – A term indicating articles of hardware designed for application to the surface of doors.
CLASS: Electric Bolt Lock (aka Electric Deadbolt)
DESIGN & OPERATIONAL ATTRIBUTES: Solenoid or motor actuated bolt with or without a mechanical key release.
1. *Electric Mortise Mount Bolt Lock
2. *Electric Surface Mount Bolt Lock
3. *Electric Gate Lock
4. *Electric Exit Device Latch Release
DHI GLOSSARY
MORTISE – A cavity made to receive a lock or other hardware.
EXIT DEVICE – A door-locking device designed to grant instant exit by pressing on a cross bar that releases the lock bolt or latch.
