Sargent and Greenleaf
General Information
The Sargent & Greenleaf Models 6128, 6129 and 6106-240 are
designed to provide a high level of security combined with
fl exible features that allow multiple levels of control over normal
operations and service access. Follow these instructions
carefully to get the best possible use from your lock.
Introduction
• A-Series electronic safe locks incorporate sophisticated
electronic circuitry. These locks are suitable for indoor use only.
• The keypad should only be cleaned with a soft, dry cloth.
Avoid the use of solvents or liquids.
• Never attempt to lubricate the lock or keypad components.
Service should only be performed by a qualifi ed technician.
• Anytime the keypad is removed from its mounting base, either
disconnect the lock cable or support the keypad so that it does
not hang by the cable. This could adversely affect the cable
connector or the keypad receptacle.
• Each time a button is pressed, and the lock accepts the input, it emits a “beep,” and the LED on the keypad lights momentarily.
• All the letters of the English alphabet are displayed on the keypad. This allows you to devise numeric, alphanumeric, or word-based
codes. Use whatever approach works best for you.
• All codes end with #. This signals the lock that you have fi nished entering all digits of the code.
• Personal data which can be directly related to a code holder, such as a birthdate, should not be used in making up a lock code.
Avoid codes which can be easily guessed.
• After the lock is changed to a new code, the lock function must be checked by locking and unlocking it several times with the
container door open. Make sure it functions correctly before closing the door.
