HES MDR-1 Push Button SG/SS NC with Guard Ring

HES MDR-1 Push Button SG/SS NC with Guard Ring

The HES MDR-1 is a stainless steel push button mechanism engineered for access control systems requiring momentary activation and fail-safe operation. Featuring a guard ring design and normally closed (NC) configuration, this control accessory integrates seamlessly with HES electromagnetic locking systems across 12VDC and 24VDC platforms.

Key Features

• Stainless steel construction for corrosion resistance and durability
• Guard ring protection for enhanced security and tamper resistance
• Normally closed (NC) configuration maintains locked state on power loss
• Push button mechanism for momentary activation
• Dual voltage support: 12VDC or 24VDC operation
• Direct compatibility with HES electromagnetic locking systems

Technical Highlights

The MDR-1 utilizes stainless steel components to withstand indoor environmental conditions where corrosion resistance is critical. The guard ring design protects the push button mechanism from accidental or unauthorized manipulation, enhancing the security profile of the installation. As a normally closed device, the MDR-1 operates in fail-safe mode—if power is interrupted, the system remains locked, preserving building security during power anomalies.

The unit's momentary activation design ensures the button only triggers an access event during active depression, preventing unintended locking or unlocking cycles. Compatible with standard 12VDC and 24VDC power supplies, the MDR-1 integrates into existing HES electromagnetic locking architectures without requiring additional conversion hardware.

Applications

Ideal for office buildings, data centers, secure facilities, and any indoor access control installation where momentary push-button activation and fail-safe locking are required. The stainless steel construction makes it suitable for areas with humidity or moderate moisture exposure.
