HES 8400LR Life-Safety Narrow Stile Mortise Exit Device
The HES 8400LR is a life-safety rated narrow stile mortise exit device engineered for aluminum and glass door applications requiring reliable egress control in institutional, commercial, and public-assembly environments. Built with satin stainless steel construction and a 1-1/8 inch backset configuration, this mechanical-only device delivers the durability and precision necessary for high-traffic facilities where controlled exit is critical.
Key Features
- Life-Safety Rated: Meets applicable egress requirements for controlled exit scenarios
- Narrow Stile Profile: Minimizes visual obstruction while maintaining full mechanical functionality
- 1-1/8 Inch Backset: Standard mortise mounting depth compatible with tight frame geometries
- Satin Stainless Steel Construction: Corrosion-resistant finish suitable for indoor and semi-protected environments
- Aluminum and Glass Door Compatibility: Engineered for seamless integration with aluminum frame and tempered glass assemblies
- No Integrated Monitoring Switch: Mechanical-only design allows external monitoring integration
Technical Highlights
The 8400LR's mortise form factor provides robust mounting security within door frame cavities, eliminating surface-mounted hardware visibility. The narrow stile configuration is purpose-built for slim-profile aluminum and glass doors common in modern commercial and institutional architecture. Satin stainless steel resists corrosion in varied indoor conditions while maintaining a professional appearance. The absence of an integrated monitoring switch simplifies installation in facilities where exit event detection is managed through external hardware or centralized facility control systems rather than door-level sensors.
Applications
Ideal for hospitals, educational facilities, corporate offices, government buildings, and public assembly spaces where life-safety egress control must meet code requirements without compromising aesthetic design. The mechanical-only operation suits integrators implementing facility-wide exit monitoring and access control strategies.
