3. Setup and Installation
This section outlines the general steps for installing the Alarm Lock T2 leverset. Professional installation is recommended to ensure proper function and security.
Door Preparation:
- Ensure your door thickness is between 1-5/8 to 1-7/8 inches.
- The lock requires two bored perpendicular holes: one in the door face and a crossbore hole in the door edge.
- The backset width required is 2-3/4 inches.
Lever Handle Orientation:
The lever handle is reversible. Determine if your door requires a right-hand or left-hand operation and adjust the lever accordingly during assembly.
Interchangeable Core Installation:
The leverset is designed to accept a standard interchangeable core from manufacturers such as Best, Falcon, Arrow, or KSP (sold separately). Install the core according to the core manufacturer's instructions to enable key override functionality.
Battery Installation:

4. Operating Instructions
This section details how to operate your Alarm Lock T2 leverset for daily use and programming.
Entering User Codes:
- Press the desired 3 to 5 digit user code on the keypad.
- The lock will provide LED indicators and an audible sound to confirm code entry.

Programming User Codes:
The lock can be manually programmed through the keypad to add, delete, or modify user entry codes. Refer to the detailed programming guide included with your product for specific instructions on master code setup and user code management.
Key Override:
If an interchangeable core is installed, a physical key can be used to engage or release the lock mechanism, bypassing the electronic keypad. Insert the key into the core and turn as required.
5. Maintenance
Proper maintenance ensures the longevity and reliable operation of your lock.
Battery Replacement:
The lock is powered by 5 AA batteries, which provide approximately 120,000 cycles. Replace batteries when the low battery indicator appears or if the lock's response becomes sluggish. Always replace all 5 batteries simultaneously with new, high-quality alkaline AA batteries.
Cleaning:
Clean the lock's exterior with a soft, damp cloth. Avoid using abrasive cleaners, solvents, or chemical sprays, as these can damage the finish and electronic components.

If you encounter issues with your Alarm Lock T2 leverset, refer to the following common troubleshooting steps:
- Lock Not Responding: Check battery levels and replace if necessary. Ensure batteries are inserted with correct polarity.
- Codes Not Working: Verify that the correct user code is being entered. Ensure the lock is not in a lockout mode. Re-program the code if unsure.
- Lever Not Engaging: Check for any obstructions around the latch bolt or strike plate. Ensure the lock is properly aligned with the door frame.
