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.
