Falcon A7851-12RX-RHR MA851 V Fail Safe Mortise Lock Case with RX Switch, Right Hand Reverse, Field Reversible

The Falcon MA851 V Fail Safe Mortise Lock Case with RX Switch (model A7851-12RX-RHR) is a commercial-grade replacement lock case engineered for electrified mortise lock applications. Configured for Right Hand Reverse (RHR) installations and featuring field-reversible operation, this lock case provides fail safe functionality, defaulting to the unlocked position upon power loss, making it well suited for access-controlled openings where free egress or entry must be maintained during a power interruption. Note that this lock case does not include an armor front; the armor front must be specified and sourced separately.

Key Features

• Fail Safe Operation: Designed to default to the unlocked state upon loss of power, supporting life-safety and access control code requirements for controlled openings.
• Integrated RX Switch: Built-in RX monitoring switch provides door position or lock status signal output for integration with access control systems and building management platforms.
• Right Hand Reverse (RHR) Configuration: Pre-configured for right hand reverse door handing to streamline installation on compatible openings.
• Field Reversible: Handing can be reversed in the field, providing installation flexibility and reducing the need for multiple part numbers on varied projects.
• MA851 V Lock Case Platform: Part of Falcon's MA851 V mortise lock case series, a proven platform for commercial-grade electrified mortise hardware.
• Armor Front Not Included: Lock case only, armor front must be selected and ordered separately to suit the specific door preparation and finish requirements of the application.
• Commercial-Grade Replacement Part: Designed as a direct replacement component for compatible Falcon electrified mortise lock assemblies, supporting long-term serviceability in commercial installations.
