LOX EM3500M Monitored Magnetic Lock 280 kg, 12/24 V DC

The LOX EM3500M is a monitored, surface-mounted electromagnetic lock with up to 280 kg holding force for compatible single-door access-control systems. It operates from 12 or 24 V DC and provides separate door-position and lock-status outputs for a connected controller or monitoring input.

Key Features

• Up to 280 kg holding force
• Selectable 12 or 24 V DC operation
• Current draw: 530 mA at 12 V DC or 260 mA at 24 V DC
• Door Status Sensor (DSS) for door-position feedback
• Lock Status Sensor (LSS) for magnetic-lock feedback
• Red and green status indication
• Built-in MOV surge protection
• Anti-tamper mounting plate
• No residual magnetism

How the Monitoring Works

The EM3500M has separate outputs for door position and lock status. These outputs can report to a compatible access controller, alarm input or building-management system. Monitored describes the locks feedback contacts; it does not include a monitoring service.

Power and Fail-Safe Operation

This is a power-to-lock device. The magnet secures the door while powered and releases when power is removed. A regulated 12 or 24 V DC power supply must be selected to suit the lock and the wider access-control system. The power supply is sold separately.

Because power loss releases the door, the complete installation must be designed around the sites security, emergency-egress and applicable compliance requirements.

Compatibility and Installation

The EM3500M suits compatible single-door access-control systems. Surface mounting space is required on the frame, with the armature aligned correctly on the door. L, Z or U brackets may be required for inward-opening doors, glass doors or frames that do not provide a suitable flat mounting surface.

Professional installation is recommended. Before purchase, confirm the door construction, opening direction, frame dimensions, cable route, controller inputs and available power capacity.

Included and Required
