A

  • AC Power

    The alternating current or voltage reverses direction at regular intervals. The voltage is thus constantly positive and then negative.

    Synonymous: Alternating voltage, alternating current (AC)

  • Adjustable latch

    The latch of some SEWOSY electric strikes is adjustable with a fit up to 3 mm, to compensate the clearance between the latch bolt of the lock and the latch strike. The adjustable roller is an advantage designated by the name ROUREG filed by SEWOSY.

  • Counterplate

    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.

L

  • Leaf

    It is the moving part of the door, which is opened or closed.
    Synonymous: swing, opening

    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.

  • Light emitting diode

    Commonly abbreviated as LED, the light emitting diode is included in the status contact which equips some VELMAG electromagnetic locks of SEWOSY. This LED lights in red to signify that the access device is unlocked, and green for the opposite.

M

  • Memory

    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.

  • Mortise

    Rectangular hollow part of the door frame in which the electric strike fits.
    Synonymous: reservation, mortice

N

  • Narrow

    Refers to an electric strike whose dimensions are smaller than those of standard strikes, and which consequently suits to narrow profiles.

O

  • OPEM

    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.

P

  • Pallet

    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.

  • Panic bar

    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.

  • Proximity reader

    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.

  • Pulling (door)

    A pulling door is open when pulled, thus inwards.

  • Pushing (door)

    A pushing door is opened when pushed, thus outwards.

R

  • Reduced aperture offset

    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.

  • Remanence

    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.

  • Signaling contact

    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.

  • Single action

    The door is pulling or pushing, but not both together.

  • Stationary contact

    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.

  • Surface mounted

    An electric strike or an electromagnetic lock can be surface-mounted on a door when it has no reservation.
    Synonymous: surface mount

  • Surface-mounted
