Whenever # is pressed, the lock chirps to acknowledge the entry. Wait for the chirps before proceeding. If a long series of closely spaced chirps (almost a continuous tone) sounds when # is pressed, the new master code will not be accepted—the old code is retained.
Note: It is very important to remember your master code. If it is lost, the manufacturer of your safe may be able to help you reset the lock. S&G does not retain any lock codes
To Enter or Change a User Code (codes #2—#9)
Press SG* (______) # (user I.D.) * (______) # (______) # (74) master code new user code new user code
Whenever # is pressed, the lock chirps to acknowledge the entry. Wait for the chirps before proceeding. If a long series of closely spaced chirps (almost a continuous tone) sounds when # is pressed, the new code will not be accepted. Any existing user code remains.
For instance, if you want to enable the #2 user code (the first user code) to open the lock with a code of 4 4 6 6 3 3, you will use the following procedure.
Press SG* (______) # 2 * 446633# 446633# (74) master code
This same procedure would change any existing #2 user code to 4-4-6-6-3-3.
To Delete a User Code
You may find that a particular user code which you have enabled is no longer needed. It is a good security policy to remove any unneeded codes. To do so, follow this procedure.
Press SG* (______) # (user I.D. 2 through 9) * # # (74) master code
Whenever # is pressed, the lock chirps to acknowledge the entry. Wait for the chirps before proceeding. If a long series of closely spaced chirps (almost a continuous tone) sounds when # is pressed, the user code will not be deleted.
Low Battery Condition
The Model 6120 lock uses two 9-volt alkaline batteries. We recommend Duracell®. If the batteries in your lock need to be replaced, twenty consecutive beeps will be heard after the last number of the code and the # sign have been pressed. The batteries will have to be replaced before the lock can be opened.
Note: A low battery simulator is built into the Model 6120 so you can familiarize yourself with how the lock sounds under a low battery condition. To activate the low battery simulator, depress the * key for approximately three seconds, until the lock emits three chirps. Immediately enter your code. Each time you press a key, the chirp will sound distinctly different than it does during normal operation. Approximately two seconds after you enter the code and open the lock, the Model 6120 will revert to normal keypad tones.
Battery Replacement Procedure (standard two-battery keypad)
The Model 6120 will NOT forget your code(s) during battery change. The circuitry is designed to hold this information for extended periods of time even if there are no batteries installed.
Changing Batteries—Two-Battery Keypad
Step 1—Remove the keypad from its mounting base. This can be done by pulling the bottom of the keypad housing away from the base (photo 1). Grip the keypad housing as shown in the photograph for best results. Support the keypad housing so that the wires which are attached to its circuit board are not pulled or stressed. Do not let the keypad hang from its wires.
Step 2—Turn the keypad over and remove both batteries. This is best done by grasping the bottom of a battery and pulling it gently away from the keypad circuit board. Do not use any type of tool to pry a battery from its holder.
Step 3—Install new batteries by pushing them directly into the battery connectors attached to the keypad circuit board. It’s important to support the connectors so they will not get bent during battery insertion (photo 2). The connectors are designed to make it very difficult to install a battery incorrectly. Pay close attention to battery polarity so as not to damage a connector by forcing a battery into it backwards.
Step 4—Hold the keypad housing close to the mounting base while you coil excess wire inside the housing (photo 3). Position the wire away from the spring clips that hold the keypad housing to the mounting base.
Step 5—Align the spring clips with the receptacles in the base. Using steady pressure, push the keypad housing back onto its mounting base. Don’t allow any wire(s) to be damaged by contact with the spring clips. The keypad housing will snap into place on the base.
Step 6—Check the master code and all user codes at least three times with the safe door open. Close the safe door only after the lock has been thoroughly checked for proper operation.
Note: The 6120 will operate with just one 9-volt alkaline battery attached to either connector. This is only recommended under emergency conditions when a second replacement battery is not available. Using a single battery will not harm the lock in any way.
Changing Batteries—One-Battery Keypad
Step 1—Keypad disassembly is neither required nor advised. The removable battery holder is accessed from the bottom of the keypad base. Pull it slightly toward the front of the keypad, then downward to remove it (photo 4).
Step 2—As you remove the old battery, you will notice there is a spring at the bottom of the holder. The new battery will rest on top of this spring to maintain good electrical contact.
Step 3—Note that the battery is oriented so that the larger contact is in line with the larger opening in the top of the battery holder (photo 5). It’s important to orient the new battery this way.
Step 4—With the new battery in the holder, slide the holder into the base of the keypad until it clicks into place (photo 6). If your lock does not operate properly, don’t press any buttons for five minutes, then try it again.
