## Long description

Electromagnetic lock QOLTEC 52459 12V symmetrical with memory and lock is a compact locking device designed for access control and door security systems. Operating at 12 volts, the lock features a symmetrical body for reversible mounting and built-in memory and lock functions that preserve the last state of the device. Intended for installations where a consistent holding force and state retention are required, this model integrates into commercial and residential setups that use electromagnetic locking principles.
Advantages
The symmetrical design allows reversible installation on left- or right-handed doors without mechanical modification. Built-in memory and lock functions retain the lock state after power interruptions or control signal changes, supporting reliable access management. Compatibility with standard 12V power supplies simplifies integration into existing electrical systems, and the compact form factor supports installation in confined frames or mounting points.

How to use
Mount the electromagnetic lock QOLTEC 52459 on the door frame according to the door swing direction, taking advantage of its symmetrical construction for left or right mounting. Connect the device to a 12 V DC power supply and to the access control system outputs (e.g., keypad, card reader, or central controller) following standard wiring practices for electromagnetic locks. Verify the memory and lock functions by testing power interruptions and control signals to ensure the lock retains or releases as required by the installation logic. Adjust alignment between the armature plate and the lock face to achieve full contact and optimal holding force.
Usage recommendations
Use a regulated 12 V DC supply with appropriate current capacity and short-circuit protection. Ensure the armature plate surface and lock face are clean and aligned to maintain maximum holding performance. Integrate the lock with compatible access control components and provide surge protection if the system is exposed to electrical disturbances.
