Security Door Controls Z7852-R-G-U Electrified Mortise Lock, Solenoid, Fail Secure, Dual Voltage, Galaxy Trim

Security Door Controls Z7852-R-G-U Electrified Mortise Lock offers a robust solution for secure access in commercial and institutional environments. This solenoid-controlled lock is designed specifically for locked outside only applications, ensuring uninhibited egress from the interior. With fail secure functionality, the lock remains secure when de-energized, making it ideal for high-security areas like equipment rooms and inner offices. Constructed with a heavy-duty mortise design, the Z7852-R-G-U features a vandal-resistant clutch mechanism, enhancing its durability against physical abuse. The dual voltage capability (12/24VDC) allows for versatile installation options, while the right-hand handing can be easily reversed in the field for custom applications. The lock is crafted from stainless steel with a satin finish, ensuring both aesthetic appeal and long-lasting performance. Key specifications include a 1-3/4" door thickness, a 3/4" throw latchbolt, and a standard ANSI 4-7/8" strike type. The Z7852-R-G-U is compatible with Schlage trim and includes monitoring contacts for added security functionality. Whether retrofitting an existing lockset or installing a new system, this electrified mortise lock is engineered to meet stringent code compliance and operational reliability.

SDC’s Electric 7800 pro and mod series solenoid controlled mortise locksets replace existing mechanical or electrified mortise locksets for the access control of openings in commercial, industrial and institutional facilities where code compliance, dependable operation and resistance to physical abuse are required. These code compliant electric mortise locksets stay latched even when unlocked, maintaining fire door integrity and eliminate the need for exposed and vulnerable electric strikes and magnetic locks or request-to-exit devices. 7800 Pro series models incorporate a grade 1 heavy duty mortise lockset and vandal resistant clutch – proprietary to all SDC locksets. They replace most brands of mechanical locksets making them fully compatible with new and retrofit applications and provide field selectability of all operational attributes. All SDC mortise locks feature a mortise cylinder to manually retract the latch.

Models:

• Z78: SDC Solenoid controlled mortise lock
• ZS78: Solenoid controlled mortise lock, SDC supplied Schlage L9080

Applications:

• Failsecure Operation: Locked when de-energized, the failsecure mode is recommended for security applications, such as inner offices, equipment rooms and security mantraps. Loss of power causes all doors to lock. Battery backup is required for continued operation during a power loss.
• Failsafe Operation: Locked when energized, the failsafe mode is recommended for fire life safety applications, such as stairwell doors, perimeter exit doors and safety mantraps. Loss of power or a signal from the life safety system causes all doors to unlock for free uninhibited access and egress.
• Locked Both Sides: Unlocked by an access control, remote control or key from either side. Field reversible operation.
• 7830: Locked both sides, failsafe
• 7832: Locked both sides, failsecure
• Locked Outside Only: Unlocked by an access control or key from the outside. Uninhibited egress at all times by turning the inside lever handle. Field reversible operation.
• 7850: Locked outside only, failsafe
• 7852: Locked outside only, failsecure
• Locked Outside and/or Inside: Unlocked by an access control, remote control or key from either side. Alternately, unlocked by an access control or key from the outside and uninhibited egress at all times by turning the inside lever handle.
• 7835: Locked outside and/or inside, failsecure outside, failsafe inside
• Deadbolt Security, Locked Outside Only: Deadbolt projected by key cylinder or thumbturn. Outside lever retracts deadbolt when electrically unlocked. Unlocked by an access control or key from the outside. Uninhibited egress at all times by turning the inside lever handle. Turning the inside lever will also retract the deadbolt.
• 7870: Deadbolt security, locked outside only, failsafe
• 7872: Deadbolt security, locked outside only, failsecure
• Deadbolt Privacy, Locked Outside Only: Deadbolt projected by key cylinder or thumbturn. Throwing deadbolt locks out electric operation of outside lever. Unlocked from the outside by key only. Uninhibited egress at all times by turning the inside lever handle. Turning the inside lever will also retract the deadbolt.
