HES KR-1-5 Key Switch Station Latch

HES KR-1-5 Key Switch Station Latch

The HES KR-1-5 is a key-operated switch station designed for secure, manual control in access control and security system installations. Featuring a latch mechanism with N/O-N/C (normally open/normally closed) dual-contact relay outputs, this unit provides reliable hardwired activation for commercial and industrial security applications where key-based access is required.

Key Features

• Key-operated switch mechanism for manual activation
• Latch functionality for sustained control output
• Dual-contact relay configuration (N/O and N/C outputs)
• NAR/302 specification compliance
• Integrated switch station form factor
• Suitable for hardwired security panel integration
• Indoor installation rated for commercial/industrial environments

Technical Highlights

The KR-1-5 integrates directly with standard access control systems and security panels that support key switch inputs and relay logic. The dual-contact design enables flexible wiring configurations for both activation and status monitoring, making it compatible with systems requiring both normally open and normally closed circuit paths. The latch mechanism ensures sustained output until manually reset, providing positive control verification in security-critical applications.

Applications

Ideal for commercial security installations, industrial control rooms, and access control systems where secure key-based manual activation is essential. Commonly deployed in facilities requiring fail-safe or fail-secure door strike integration, emergency release systems, and manual override stations.
