  • No. In order to release a door using the included proximity cards they must first be programmed to the system using the included software. 

  • The magnetic lock is suitable for both in-swinging and out-swinging doors. Brackets (L bracket, LZ bracket, U bracket) are 

    used to orient the armature for use with both applications. Filler plates are also used to provide a large, flat mounting area 

    on the door frame when the electromagnet is larger than the available mounting space on the door frame due to the frame's geometry.


    The magnetic lock should always be installed on the secure side of the door. Most installations are surface mounted. 

    For safety, magnetic lock, cables, and wires should be routed through the door frame or flush mount with wire moulding.


    Installation is straightforward. With in-swinging applications, the electromagnet is typically installed in the opening corner of the 

    door at the door's header. Maglocks can also be installed vertically in the door opening when they are furnished with a full length housing. 

    With this configuration the armature is through-bolted through the door and oriented to mate with the face of the electromagnet. 

    The armature plate and electromagnet must touch in order to provide locking holding force.


    With out-swinging applications, the electromagnet is typically installed on the side of the door header. In this configuration, 

    the armature is mounted on a Z shaped bracket that orients the armature to mate with the electromagnet.


    Magnetic locks are almost always part of a complete electronic security system. Such a system may simply consist of an attached 

    keycard reader or may be more complex, involving connection to a central computer that monitors the building's security. 

    Whatever the choice of locking system, fire safety is an important consideration.


    Other variations and improvements on the electromagnetic locks have been developed. The most remarkable is the shear lock, 

    where the armature does not directly pull off the face, but the load is instead in shear, like a mechanical stop. The shear magnetic lock 

    allows a door to swing in both directions, as opposed to the original (and now ubiquitous) direct pull type, which normally works 

    either in an in-swing or out-swing configuration. In order to provide the shear magnetic lock with the appropriate holding force, 

    then two pins lock the armature onto the magnet itself, and ensure that the magnet locks into place.


    If you have any inquiries for installation, pls kindly contact us, sales@s4a-access.com we have our own manufacture and 

    within 12years production experience for magnetic lock,All locks, we provide OEM and ODM service and 1 year quality guarantee.

  • Different frequencies have different characteristics that make them more useful for different applications. 

    For instance, low-frequency tags are cheaper than ultra high frequency (UHF) tags, use less power and 

    are better able to penetrate non-metallic substances. They are ideal for scanning objects with high-water content, 

    such as fruit, at close range. UHF frequencies typically offer better range and can transfer data faster. 

    But they use more power and are less likely to pass through materials. And because they tend to be more "directed," 

    they require a clear path between the tag and reader. UHF tags might be better for scanning boxes of goods 

    as they pass through a bay door into a warehouse. It is probably best to work with a consultant, integrator or 

    vendor that can help you choose the right frequency for your application

  • The recommended cable types are "22 gauge 6-conductor shielded" for Readers and 18 gauge 4 or 6 conductor cable 

    for the locking hardware. Deviation from these recommendations may cause unexpected behavior and or invalidation of your equipment warranty.

  • For safety purposes, electric locks and electric strikes can be designed to operate in one of two modes:


    Fail-safe –to protect people: The lock is released if power cuts off.


    Fail-secure (also known as non fail safe) to protect property: The lock remains closed if power cuts off.

    This type of lock has a cylinder, similar to those found in conventional locks. The cylinder makes it possible for the lock to remain secure,

    even if the power supply is cut off.


    An electromagnet lock is ONLY Fail-Safe, so it must satisfy applicable fire regulations so as to be safe in emergency situations.

  • Most countries have assigned the 125 kHz or 134 kHz area of the radio spectrum for low-frequncy systems, 

    and 13.56 MHz is used around the world for high-frequency systems. But UHF RFID systems have only been around since the mid-1990s 

    and countries have not agreed on a single area of the UHF spectrum for RFID. Europe uses 868 MHz for UHF and the U.S. uses 915 MHz. 

    Until recently, Japan did not allow any use of the UHF spectrum for RFID, but it is looking to open up the 960MHz area for RFID. 

    Many other devices use the UHF spectrum, so it will take years for all governments to agree on a single UHF band for RFID. 

    Government's also regulate the power of the readers to limit interference with other devices. Some groups, 

    such as the Global Commerce Initiative, are trying to encourage governments to agree on frequencies and output. 

    Tag and reader makers are also trying to develop systems that can work at more than one frequency, to get around the problem.

  • Our advantages: easy to install, easy to use, easy to upgrade, high stability and compatibility. 

    You may find we don't have a lot of models, but all these models are S4A's elite of 10 years experience in this industry.

  • The minimum you need is the lock, power supply and a request-to-exit button. The request-to-exit button unlocks the door for exit, 

    but most local fire codes require at least 2 methods to unlock the door.


    There are a few components that are required for a magnetic lock installation:


    1-1: Select a Magnetic Lock. You should choose a lock strength (EL-600 to EL-1200 ) =600-1200lbs appropriate for your door.

    1-2: Add a Power Supply with Battery Backup. Model is: PS-300B is a good choice.

    The battery backup is critical to ensure that your door stays locked if the power goes out.


    1-3: dd a Request-to-Exit Button, which will unlock the door when pushed.EB series or non-touch version. EB-16 or EB-17


    1-4: Add an optional Motion Sensor, which will unlock the door automatically when someone approaches the door from inside.

    Model is M-204


    Also, you could choose a Relay Timer to keep the door unlocked for a specific time period, to allow for the delay 

    between when a person presses the Request-to-Exit button and when they push open the door.
