HES KR-3 Latching Key Reset Mechanism

HES KR-3 Latching Key Reset Mechanism

The HES KR-3 is a latching key reset mechanism engineered for professional access control installations requiring manual reset functionality. Designed for integration with HES electric strike systems and standard security architectures, the KR-3 provides reliable latching control with dual normally closed (N/C) contacts for auxiliary circuit management.

Key Features

• Latching key-operated reset mechanism for manual override capability
• Two normally closed (N/C) contacts for auxiliary control circuits
• Compatible with 12/24 VDC control panel architectures
• Integrates seamlessly into HES electric strike installations
• Supports parallel and sequential control logic in wired security systems
• Compact form factor suitable for OEM and retrofit applications

Technical Highlights

The KR-3 operates across standard 12/24 VDC control systems commonly deployed in access control networks. The dual N/C contact configuration enables flexible circuit design, allowing integrators to implement both independent reset functions and coordinated multi-door sequences. The latching mechanism ensures positive engagement and prevents accidental reset, critical in high-security environments where intentional manual intervention is required.

Applications

• Commercial building access control systems
• Electric strike reset and monitoring circuits
• Emergency exit door management
• Building automation auxiliary controls
• Security system integration and expansion

The HES KR-3 is ideal for system integrators and facility managers implementing or upgrading access control infrastructure where manual reset capability and reliable latching control are essential design requirements.
