Door and Frame Dimensional Requirements
Proper mechanical preparation is critical to ensure the reliable operation of the Samsung SHS-P718 digital mortise lock. Before mortising, verify that the door structure meets all physical dimension thresholds. The lock is engineered for mounting on standard wooden or steel doors with a leaf thickness between 40 mm and 80 mm.
The installation requires a backset clearance of exactly 70 mm from the door edge to the center of the handle spindle hole. In addition, the door stile must provide a clear, unobstructed flat surface with a minimum lock stile width of 115 mm to accommodate both the lock body footprint and internal structural mountings. Installers must also inspect the gap between the door leaf edge and the door frame strike plate; this clearance gap must not exceed 5 mm. Excessive clearance beyond 5 mm will prevent proper latch engagement and compromise the mechanical integrity of the deadbolt.
Mortise Pocket and AML320 Mechanism Integration
The lock utilizes an AML320 two-way latch mortise assembly tested to withstand 300,000 operational cycles. Prepare the door stile cutout according to standard AML-320 mortise dimensions. When routing the mortise cavity, ensure clean vertical and horizontal edges to prevent friction against the internal mechanical linkage.
Feed the electrical connection cables through the preparatory routing channel from the mortise cavity to the front and back panel positions. Avoid sharp cable bends or pinches against the structural reinforcement plates during assembly. Secure the mortise casing firmly into the door edge using the designated mounting screws, ensuring the faceplate sits completely flush with the door leaf perimeter.
Reversible Handing and Push-Pull Handle Assembly
The Samsung SHS-P718 features a universal reversible design that allows field configuration for either left-handed or right-handed door swings. Adjust the handing selector mechanism on the chassis prior to securing the escutcheon assemblies. The integrated push-pull handle architecture physically covers the key-tail pathway to prevent forced entry via punching attacks.
Position the exterior body—measuring 86 mm (W) x 387 mm (H) x 61 mm (D)—against the outer door face, routing the primary communication cable through the lower access borehole. Align the interior mounting plate and firmly bolt it through the door core into the exterior housing threaded posts. Connect the wiring harness to the designated PCB sockets on the interior body, which measures 86 mm (W) x 354.8 mm (H) x 63 mm (D), and attach the interior assembly to its mounting bracket.
Power Supply Setup and Sensor Commissioning
The lock operates on a DC 6V electrical circuit powered by 8 AA alkaline batteries (they are not included) installed in the interior battery compartment. Do not mix old cells with new cells during commissioning. After loading the 8 AA alkaline batteries (they are not included), confirm that the audio-visual indicator illuminates and verify the latch deadbolt throw by cycling the push-pull handles.
Check the integrated infrared (IR) welcome motion sensor, which detects user approach within a 70 cm range to automatically illuminate the numeric touchscreen. If the primary power depletes completely in service, an external 9V battery (they are not included) can be pressed against the external power contact terminals on the bottom of the exterior body to temporarily supply emergency power for credential verification, or the physical emergency override key can be inserted directly into the hidden key cylinder.
