The counterplate is the necessary complement of the electromagnetic lock that will allow the locking and unlocking of the passage. The magnetic field generated by the electrical supply creates an adherence between the electromagnetic lock and its armature plate, keeping the access closed when the fail-safe system is used. This is the case of most SEWOSY electromagnetic locks, together with their counterplates.
Synonymous: Armature plate
CPREG is a registered trademark of SEWOSY, designating the electromagnetic housings created by the company. The armature plate of CPREG aluminium housings can be adjusted in case of door sagging through a sliding system. Three generations of CPREG aluminium housings are currently marketed: the 1, 2 and 3. The eco-friendly CPREG 4 and 5 will be launched on the market in 2016.

Synonymous: DC Power, DC
A double action door can be opened in the two directions, by pulling or pushing it.
A double swing door is made of two leaves. The door can be single action, pulling or pushing, or double action, meaning that it can be opened in the two directions.
The unlocking of the electric strike is caused by power on or electric impulse, whereas in the absence of power, the strike remains locked.
Synonymous: fail-secure, power on
Metal housing fitted with an electromagnet device which releases remotely the latch bolt of a lock, by means of an electronic control organ.
In France, an electromagnetic lock is a control adaptor device: a DAC. Locked or unlocked by power supply, an electromagnetic lock can be mounted on the frame or on the upper door rail of the access, while its counterplate can be laid on the leaf.
A flush-mount electric strike must be mortised in the reservation designed for this purpose. The other way to fit a strike is to surface-mount it on the door frame.
Synonymous: to mortise, mortice, flush mounted
Ability of an electric strike or electromagnetic lock to resist the pressure, which is measured in Newton Deca (DAN).
A horizontal lock is wider than tall, the latch bolt being then in the lower part of the lock.
Remote access control device functioning by dialing on the keypad.
It is the moving part of the door, which is opened or closed.
Synonymous: swing, opening
Plural of leaf. Refers to the moving parts of doors. A door can have two leaves.
LED is the abbreviation for “light emitting diode“. Comprised in the status sensor of some SEWOSY electromagnetic locks, the LED indicates the status of unlocking by red color, and of locking by green color.
An electric strike with memory, also called “bi-stable” or “back and forth“, is unlocked by power on. It registers its unblocking as long as the door is not actuated, by a mechanical device maintaining the latch pressed on the pallet of the device. When the door is closed again, the pallet is released and the electric strike is locked again.
Rectangular hollow part of the door frame in which the electric strike fits.
Synonymous: reservation, mortice
Action of installing the electric strike in the reservation.
Synonymous: flush mounting
Rectangular hollow parts of door frames in which electric strikes are embedded.
Refers to an electric strike whose dimensions are smaller than those of standard strikes, and which consequently suits to narrow profiles.
Mechanical system of permanent opening. It comes to a lever which must be actuated in a direction to maintain the electric strike unlocked and then again in the other direction to allow re-locking of the access.
In cases where the SEWOSY electric strike comprises a signaling or status contact, the pallet enables to optimize the fit of contact, regardless of the type of latch. For the memory electric strikes, the pallet is blocked by the latch bolt as long as the door is not closed again.
Horizontal bar fitted on an emergency exit, enabling to leave a building from inside to outside by mechanical push, even if the door is locked.
Device for remote access control running through Radio Frequency Identification (RFID). It allows to remotely identify the user of a badge, card or key chain integrating technology of Marin type, for example, or other. The proximity reader can also be provided with a keypad unlocking access by manual dialing.
A pulling door is open when pulled, thus inwards.
A pushing door is opened when pushed, thus outwards.
The latch of some SEWOSY electric strikes has the ability to rotate on itself, thus requiring less space. This often avoids the lateral cut of the door frame. The reduced aperture offset is a benefit designated by the ROUREG trademark of SEWOSY.
The magnetic field of a standard electromagnetic lock can persist when power cut: this is the remanence phenomenon. This delays the door unlocking and requires more effort to push the door. The presence of an ejector in the counterplate allows canceling the remanence, so to neutralize the magnetic field. This anti-remanence system is integrated in all SEWOSY electromagnetic locks.
The information on the open or closed door position, or its unlocked or locked status, is transferred remotely to a centralization organ or dashboard.
Rectangular hollow part of the door frame in which the electric strike fits.
Synonymous: mortise, mortice

Brand filed by SEWOSY, designating the electric strikes featuring a reduced aperture offset, and an adjustable latch with a 3 mm tolerance.
Door position sensor built-in electric strikes to send an information about the opening or closure of the door to a management organ or dashboard.
The door is pulling or pushing, but not both together.
It’s a mechanical memory‘s system that keeps the bolt pressed on the electric strike pallet as long as the door is not closed. Therefore, the electric strike memorizes its unlocking, which results in the stationary contact.
An electric strike or an electromagnetic lock can be surface-mounted on a door when it has no reservation.
Synonymous: surface mount
Mounting is performed on the door frame when it has no reservation (wooden doors or gates for example) for an electric strike, or to facilitate the fitting of an electromagnetic lock.

The time delay is programmed by the installer to hold the release for a specific period of time, usually a few seconds.
A mortise electric strike must be built-in in the reservation designed for this purpose.
Synonymous: flush-mount, built-in
