JANTEK JEB-250 Electromagnetic Bolt Lock 12/24V DC Reversible Adjustable Release Delay

Product Overview

The JANTEK JEB-250 is a reversible electromagnetic bolt lock intended for access control systems in commercial and institutional environments, where doors require secure electric locking and fail-safe operation. Constructed from stainless steel for the critical components and an aluminum housing, it supports direct current supply at either 12V or 24V DC, suitable for integration in office buildings, server rooms, and secure areas.

What distinguishes the JEB-250 is its selectable release delay mechanism, allowing adjustment between 0, 3, 6, or 9 seconds. This feature is particularly valuable for B2B buyers who need to tailor the lock's operation to specific door-closing mechanisms or user flow, reducing installation errors and ensuring compatibility with fire safety or building automation requirements. This lock is advisable for bulk procurement in modern security upgrades, especially where adjustable release timing is critical for compliance or workflow.

Key Features

• 12/24V DC dual voltage ? supports both common power supply standards for flexible system integration


• Reversible (NO) operation ? bolt retracts on power loss for fail-safe (emergency exit) applications


• Selectable release delay ? adjustable holding time after door closure (0, 3, 6, 9 sec)


• Stainless steel bolt and faceplate ? high durability and resistance to tampering


• Position status output ? provides signal for door closed/open state to central control panels


• Incorrect position blocking ? lock refuses activation if the door is not properly aligned


• Built-in protection ? safeguards against overvoltage and reverse polarity

Applications

Ideal for access control in office buildings, schools, server rooms, cabinets, and institutional doors requiring electric fail-safe locking. Suitable for systems with fire exit, emergency escape requirements, and for integration with building automation or security signaling thanks to position output and delay adjustment. Can be used in both new installations and security retrofit projects.

Packaging & Shipping

Standard export packaging. Each unit includes the electromagnet bolt lock, stainless steel strike plate, installation accessories, and a wiring diagram manual.
