Electromagnetic Reversible Door Lock Dantom JS-1504N — fail-safe/hold-open electric strike

Dantom JS-1504N is a reversible electromagnetic door lock designed as an electric strike for controlled door release in access control installations. The device fits into standard door frames and allows remote unlocking and secure holding of the latch by applying an electrical signal. The JS-1504N supports reversible operation, making it suitable for doors that require either fail-safe (unlocked on power loss) or hold-open behavior depending on installation wiring and configuration.

Advantages

The lock provides reversible fail-safe/hold-open operation allowing flexible integration with access control systems. Its electric-strike design enables retrofit into many frame types without replacing the existing lockset. The unit is engineered for reliable electrical activation and consistent mechanical engagement, reducing door operation issues and simplifying remote release. Compact form factor and straightforward mounting help speed up installation and maintenance.

Suitable for

• Office interior and exterior doors with access control
• Residential entry doors and apartment block entrances
• Commercial premises where remote release is required
• Doors requiring reversible fail-safe or hold-open functionality

Key specifications

• Reversible operation allowing fail-safe or hold-open mode
• Electric strike / electromagnetic bolt design for frame installation
• Designed for remote electrical activation and controlled unlocking
• Compact dimensions suitable for standard door frames
• Compatible with common access control wiring and power supplies

How to use

Install the Dantom JS-1504N into the door frame aligned with the existing latch or deadbolt according to frame cutout dimensions and manufacturer mounting instructions. Connect the lock to the access control system or push-button release using appropriate power and control wiring; configure the wiring for the desired reversible mode so the unit operates either as fail-safe (releases on power loss) or as hold-open when energised. After mechanical mounting and electrical connection, test door operation through multiple cycles to ensure reliable engagement and release, and adjust strike alignment if necessary for smooth latching.

Usage recommendations

Use compatible power supplies and follow local electrical codes when wiring the unit. Verify compatibility with the door’s lockset and frame prior to installation and perform routine inspections to check electrical connections and mechanical wear. For environments with high security requirements or heavy traffic, consult a qualified installer to ensure correct mode selection and durable mounting.
