Control a right-hand access-controlled opening with a fail-secure solenoid lock configuration. Fail-secure operation keeps the door secured when power is removed, while an electrical release signal changes the locking state for authorized entry. The right-hand handing identifies the door orientation this hardware is built to serve, helping installers match the lock to the opening before installation. Security Door Controls Z7852RQNE combines solenoid actuation, right-hand handing, fail-secure operation, and finish code 626 in one specific configuration. These details matter when replacing installed door hardware or specifying an electrified locking point for a controlled opening. Handing and operating mode must match the existing door preparation, access-control sequence, and site egress design. Within the 7852 family, this version is distinguished by its right-hand configuration and fail-secure locking behavior. Finish code 626 provides the specified exterior finish designation for coordinated door hardware selections. Select this unit when the opening calls for a right-hand solenoid lock that remains locked during a power interruption rather than releasing the door.
