## Long description

QOLTEC electric strike 52458 is a reverse-operation (fail-secure) door strike designed for integration with access control systems. It operates from a 12V DC supply and draws up to 300 mA, providing secure locking when power is removed. The unit is suitable for installation in metal or wooden door frames and is compatible with electronic locks, intercoms and access controllers used in offices, apartment entrances and secure rooms.
Advantages
The strike’s reverse operation mode ensures the door remains locked when power is cut, supporting security policies that require fail-secure behavior. Its 12V DC rating and 300 mA current consumption make it compatible with common low-voltage access control power supplies. The compact mechanical design allows mounting in both metal and wooden frames and simplifies integration with existing intercoms and access control panels.
Suitable for
 Office entry control systems
 Apartment building main entrances with intercoms
 Secure rooms and cabinets requiring fail-secure locking
 Retrofit installations in metal or wooden frames
Key specifications
 Operating mode: reverse operation (fail-secure)
 Supply voltage: 12 V DC
 Current consumption: 300 mA
 Suitable mounting: metal and wooden door frames
 Compatibility: electronic locks, intercoms, access controllers
How to use
Mount the electric strike into the prepared recess in the door frame following the frame manufacturer’s guidelines and the strike’s mechanical dimensions. Connect the 12V DC supply and control wiring according to the access control system wiring diagram, ensuring correct polarity and secure connections. Configure the access controller or intercom to provide the appropriate control signal; when the strike receives power it operates in reverse mode so that removal of power returns the latch to the locked position. Test locking and release cycles several times after installation to verify reliable operation.
Usage recommendations
Use a regulated 12V DC power supply sized to handle the 300 mA load plus any additional margin for wiring losses and other connected devices. For retrofit projects, confirm frame recess dimensions and strike outline before cutting. Regularly inspect mechanical parts and wiring for wear or corrosion, and follow local fire and safety codes regarding fail-secure devices in escape routes.
