Electrified Cylindrical Locksets
ACCESS CONTROL CAPABILITIES WHILE MEETING FIRE LIFE SAFETY CODE COMPLIANCE
Electrified cylindrical locksets are similar to mechanical cylindrical locksets but include a built-in solenoid to keep the latch from retracting when turning the handle from the outside of the door. From the inside of the door, the latch can be retracted by turning the handle, ensuring free egress for code compliance.

Entering the door from the outside requires a key or access control to disengage the solenoid, allowing the latch to retract when turning the handle. Electrified cylindrical locksets are typically less expensive than electrified mortise locksets and are well suited for both new and retrofit construction.
Additional features include:
- Compatible with any type of access control
- Available as failsafe or failsecure
- Available in a variety of trim and finish options

Application
SDC's Electra™ 7200 series solenoid controlled cylindrical locks are designed 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 cylindrical locksets stay latched even when unlocked, maintaining fire door integrity and eliminating the need for exposed and vulnerable electric strikes and magnetic locks or request-to-exit devices.
7200 series models incorporate a grade 1 cylindrical lockset and vandal resistant clutch – proprietary to all SDC locksets. 7200 series locks come standard with built-in latch status monitoring, REX optional. They replace most brands of mechanical locksets making them fully compatible with new and retrofit applications.
Electrified cylindrical locks may be used on non-fire-rated and fire-rated wood, mineral core and hollow metal doors. Additionally, SDC's building code compliant 7200 Series electrified cylindrical locksets stay latched even when unlocked, maintaining fire door integrity. This basic ability complies with national code requirements for up to 3-hour fire-rated doors, including elevator lobby and stairwell doors where electromagnetic locks and electric strikes are not permitted.
Electrified cylindrical locks eliminate the need for exposed and vulnerable locking devices, such as electric strikes, magnetic locks and remote request-to-exit devices. Additionally, they are ideal for high profile installations that require high security or superior appearance. Facility applications include: commercial high-rise buildings, industrial and technology centers, healthcare, transportation, government and military facilities, museums and universities.

Failsafe vs Failsecure
Failsafe - Z7250
Locked when energized, the failsafe cylindrical electric lock function, model Z7250, is ideal for interior door and exit door applications. Unlike a magnetic lock, the Z7250 is never locked from the inside and permits uninhibited egress at all times by turning the inside manual lever handle. This also eliminates the need for secondary egress switch devices, such as motion detectors, wall mounted exit switches and switch bars. When connected to the fire life safety command center, the lock releases immediately in an emergency, transforming a stairwell or elevator lobby door from a one-way exit into a two-way exit. This permits re-entry and eliminates the possibility of stairwell entrapment and potential exposure to life threatening smoke inhalation. Additionally, firefighters are permitted uninhibited access to all floors during an emergency, speeding lifesaving and fire extinguishing efforts.
Failsecure - Z7252
Unlocked when energized, the failsecure cylindrical electric lock function, model Z7252, is ideal for interior high security applications. The Z7252 is never locked from the inside and permits uninhibited egress at all times by turning the inside manual lever handle. This also eliminates the need for secondary egress switch devices, such as motion detectors, wall mounted exit switches and switch bars. Battery backup power supplies may be specified to provide power for operation during power outage.

Electrified Locks and Fire Ratings
Installing an electrified lock on a fire-rated door can void the door's fire rating. Use fire-rated locks, like SDC's 7200, for fire-rated openings. It is important to note that retrofitting an electrified lock on a fire-rated door can void the door's fire rating when door core drilling is required for a wire raceway. It is crucial that the lock is installed to allow for a rated door assembly to be re-certified after installation. For recertification, the Warnock Hersey (WH) Mark is the leading fire product safety and performance mark for building and construction products. Manufacturers and AHJs have viewed WH as the preferred mark for fire safety certification. Products bearing the Warnock Hersey certification indicate compliance to relevant building codes, association criteria, and product safety and performance standards.
Using improperly rated locks can void the rating as well as any drilling, cutting, or non-original penetration to the door or frame. On fire doors with ratings of 45 minutes or higher, an electrified lock must be installed so that it does not allow fire or smoke to penetrate. This is accomplished in originally rated assemblies by making sure the wiring is inside ANSI electrical pockets built into the door or frame. Fire code officials are serious about not allowing fire and smoke to penetrate fire-rated doors. We recommend you pay particular attention to the manufacturer's installation instructions as well as product listings and certifications before proceeding.

Door Core Drill Guide
Typically fire rated hollow metal doors will require preparation for wire preps by the door supplier to maintain their fire rating. However, the SDC door core drill fixture kit provides the best method of field wire preparation for fire rated or non-fire-rated particle filled and wood doors to accommodate the installation of electrified locksets, exit devices and hinges while maintaining the door integrity and rating. The installer may call for inspection of fire-rated doors for re-certification when installation is complete.

- Evacuator drill bit standard
Power Transfer Hinge
Installed in the center hinge position of the door, the PTH series electric hinge provides the concealed and vandal resistant wires required between the door and the frame for the purpose of powering and monitoring the access controlled locks. Choices include a 4-wire hinge for basic applications that may include a request-to-exit output and a 10-wire hinge to accommodate multiple remote lock status outputs, such as door status, latch status, locked status and request-to-exit.
