Sdc Z7852LQE Fail Secure Mortise Lock Left Hand 12V

Product Description

The SDC Security Door Controls Z7852LQE is a fail secure electric mortise lock designed for left-hand door applications. In a fail secure configuration, the lock remains locked when power is removed, maintaining security during power outages or system failures. This unit operates on 12 volts and is built for access control installations where maintaining a locked state during power interruptions is a code or security requirement. It is typically installed by licensed locksmiths, access control technicians, or commercial door hardware specialists working in commercial or institutional environments.

The Z7852LQE is suited for commercial door applications requiring integrated electric locking hardware within the door mortise pocket. Its fail secure operation makes it appropriate for server rooms, secure offices, detention areas, and other controlled-access spaces where an unlocked door during a power loss is not acceptable. The left-hand configuration must be confirmed against the door handing before installation.

Key Features

• Fail secure operation — lock remains locked when power is lost
• Left-hand door configuration
• 12V operating voltage for compatibility with standard access control power supplies
• Mortise-style form factor for in-door integration with compatible mortise lock chassis
• Single unit per package for individual door installations

Compatibility

Designed as an OEM-style electric mortise lock replacement or new installation component for commercial left-hand door applications requiring fail secure access control integration.

Installation Notes

Installation should be performed by a qualified locksmith or licensed access control technician familiar with commercial door hardware and low-voltage wiring. Disconnect and lock out all power to the access control system before beginning installation or servicing. Confirm door handing before ordering, as left-hand and right-hand mortise locks are not interchangeable. Local building codes and fire egress requirements must be verified prior to installing fail secure hardware on any door in a path of egress.
