The LockMasters LockOne LKM10K is a pedestrian door lock device designed for security applications. Documentation indicates it is available as an exit-only model and is GSA Approved FF-L-2890C Lock Type I & II. The device is intended for use on doors with thicknesses of 1-3/4” and 2”. Installation requires specific attention to door handing (left or right) and may necessitate the use of a key override feature. This article details the installation process and components based on available documentation.
Device Overview and Components
The LockMasters LKM10K is presented as a second-generation pedestrian door lock. The device arrives fully assembled. Key components include the base plate, spindles, retaining alignment rings, tool base plate cover, base plate cover, and a change key plug. Additional components that may be used in conjunction with the LKM10K include an S&G 2740B lock shield, a light indicator collar, a light indicator lens, a spindle alignment tool, an acrylic light pipe, Security Door Controls 920 keypad, and a Securitron PSP-24 DC power supply.
The documentation specifies two spindle sizes: 1-3/4” and 2-5/8”. These spindles, along with retaining alignment rings, are included with the device. The base plate is supplied with a cover, designated as “B” and “C”.
Installation Instructions – General Procedure
Installation of the LKM10K requires careful attention to detail. The process begins with aligning the pre-punched bail on the exterior trim side of the door. A horizontal line should be extended from this point across the door, continuing at least 10 inches. This line serves as a guide for marking the template.
The documentation references an exterior trim mounting template, available in both left-hand (Part Number: 10KELHTMP) and right-hand (Part Number: 10KERHTMP) configurations. These templates are used to mark the locations for drilling holes for mounting the exterior trim. The template includes markings designated as “B”, and dimensions of 5/8”.
Door Preparation and Template Usage
Prior to drilling, it is crucial to determine the bevel edge of the door. A horizontal line is established based on the high side of the bevel. The exterior trim template is then aligned with this line. Once aligned, the template is used to center punch all the holes that will be drilled.
Specific drilling requirements vary based on door material. For fire-rated doors, a 5/16” wood drill bit must be used for the raceway escutcheon. For metal doors, a 5/16” metal drill bit is required for the wire entry hole (designated as “F”).
Key Override Feature Installation
The LKM10K supports a key override feature, though instructions indicate users should refer to separate instructions before drilling for this feature. Lockmasters recommends using an interchangeable core rim cylinder to facilitate re-keying. The documentation includes a figure illustrating a sample template for right-hand doors (Part Number: 10KERHTMP).
Handing Considerations
The LKM10K is designed to accommodate both left-hand and right-hand doors. The appropriate exterior trim mounting template must be selected based on the door’s handing. The documentation provides separate part numbers for left-hand and right-hand templates.
Additional Notes and Resources
The documentation references a QR code that, when scanned with a smartphone camera, provides access to a detailed video of the installation instructions. An optional 1/8” Hex Wrench is recommended as a tool for installation.
Compatibility and Standards
The LockMasters LockOne LKM10K is noted as being GSA Approved FF-L-2890C Lock Type I & II. The documentation explicitly states that the exit-only model is not FF-L-2890B approved. The device is compatible with Security Door Controls (SDC) 920 Push Pull Handle models.
Conclusion
The LockMasters LockOne LKM10K is a security device intended for pedestrian doors. Successful installation requires careful adherence to the provided instructions, including proper door preparation, template usage, and consideration of door handing. The key override feature offers additional flexibility, and compatibility with SDC 920 handles expands its potential applications. The device’s GSA approval indicates adherence to specific security standards.
