Sargent and Greenleaf 6120 User manual
The Sargent & Greenleaf Model 6120 combines ease of operation with security. Its advanced
electronic circuit design makes it easy to open and easy to change codes. Follow these
instructions carefully to get the best possible use from your lock.
INTRODUCTION
• The Sargent & Greenleaf Model 6120 Motorized Electronic Combination Lock is shipped from the
factory with a factory master code only. It is 1 2 3 4 5 6 #. This code is used to open the lock
and set or change all of its codes. If the safe maker or your dealer sets a new master code, he will
advise you of the change. You should set the lock to your own, unique master code immediately.
• The Model 6120 will always open on the master code. At your discretion, it can also be set to
accept up to eight different user codes. The master code holder is responsible for maintaining the
number of active users programmed into each lock. The master code is designated as code #1,
and the user codes (if set) are designated by user I.D. number 2, 3, 4, 5, 6, 7, 8, and 9. The
user codes do not exist until they are programmed into the lock.
• Each time a button is pressed and the lock accepts the input, it emits a “chirp,” and the LED on the
keypad lights momentarily.
• All codes must contain six digits or six letters. Any digit or letter can be used as many times as you
wish. For instance, the following codes (while not recommended) will operate the lock:
5 5 5 5 5 5 # OR J J J J J J #
• All codes end with #. This signals the lock that you have finished entering all digits of the code.
• If you pause more than 10 seconds between pressing buttons when entering a code, the lock will
assume you do not want to continue, and it will reset itself to the original code. To open the lock,
begin the code entry sequence from the first step.
• If you realize you have pressed an incorrect button when entering a code, press* or simply pause
ten seconds or more, then begin entering your code again.
• If four incorrect codes are entered in a row, the Model 6120 will shut down for a period of up to
fifteen minutes. This is a security feature. Pressing any button anytime during the lockout period will
resent the timer to its maximum penalty time. Do not touch any keypad buttons for a period of
fifteen minutes, then enter any valid code to open the lock.
• The model 6120 does not have audit trail capabilities.

TO OPEN THE LOCK . . .
Press the code digits or letters in order, followed by #. The lock bolt will retract for six seconds,
allowing you time to operate the safe handle and open the door. Do not put any pressure on the
safe handle until after the code has been entered. The Model 6120 will lock automatically when
the safe door is closed and the handle is turned to the locked position.
If all of the preceding remedies have been exhausted and the lock still does not open, contact a
qualified safe technician in your area for professional service.

WARNING: No Audit Trail Capabilities. Note: The Master Code Holder is responsible for maintaining the number
of active users programmed into each lock.
IN CASE OF TROUBLE
If your lock should fail to open when a valid code is entered, check for the following:
1. The boltwork of a safe can, under certain conditions, place pressure on the side of the
lock’s bolt. This is often caused by something inside the safe pressing against the door or by
something caught between the safe door and its frame. When this occurs, the lock will not
operate properly. To relieve side pressure on the lock bolt, move the safe’s handle to the fully
locked position, then re-enter a working code. The lock should open.
2. If the lock “chirps” when keys are pressed, but it will not open, the batteries may be
drained to the point that they will not operate the lock’s motor. Follow the battery replace-
ment procedure in this manual.
3. If the lock makes no sound when any of the keys are pressed, dead batteries are likely to
be the cause. Follow the battery replacement procedure in this manual.
4. If the lock makes no sound when any of the keys are pressed, but the batteries have
been checked and found to be good, a loose keypad connector may be the cause. Pull the
keypad away from the base as described in the battery changing procedure. Check to make
sure the wire connector is firmly seated into its receptacle on the keypad circuit board. The
connector is designed so that it will only slide into the receptacle when aligned correctly.
ABOUT CHANGING CODES . . .
All code changing procedures begin by pressing S G *(the same as 7 4*), followed by the
existing six-digit master code and #. The lock immediately chirps five times ().If the lock
emits a series of closely spaced chirps (almost a continuous tone) you have made a mistake and
must start again. Always keep the safe door open when making programming changes.
TO CHANGE THE MASTER CODE (CODE #1) . . .
Press S G * (______) # 1 *(______) # (______) #
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 manuafacturer 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 S G *(______) # (user I.D.) * (______) # (______) #
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 S G * (______) # 2 * 446633# 446633#
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 S G *(______) # (user I.D. 2 through 9) * # #
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.
The 6120 lock will not allow you to inadvertently remove the master code.

SECURITY ADVISORY
If your lock is used many times a day (50 or more openings daily), it is advisable to use as many
different keys as possible in your code number. Avoid using a key more than once whenever pos-
sible. Check the keypad frequently for visible wear which might indicate which keys are being
pressed for code entry. Change the code to use different keys when wear is evident. If neces-
sary, have a qualified service technician replace the keypad.
TO USE THE TIME DELAY . . .
The Sargent & Greenleaf Model 6120 Electronic Combination Lock has a built in time delay fea-
ture that you can turn on and off by following the programming steps on this page. The time
delay can be set anywhere from 0 to 9 minutes. When the time delay feature is enabled, your
lock will function as follows:
After you enter a valid opening code, the lock will “chirp” three times. It will not open.
The lock will “chirp” once every ten seconds during the delay period, and it will not accept
any keypad input during the delay period.
The lock will “chirp” ten times at the end of the delay period.
You must enter a valid opening code within two minutes of the end of the delay period. The
lock will open. Instead of entering a valid code, you can use the procedure below to turn the
time delay off or set it to a different length. THE TWO MINUTE PERIOD IMMEDIATELY FOLLOWING
THE TIME DELAY IS THE ONLY TIME DURING WHICH YOU CAN CHANGE OR DELETE THE TIME DELAY.
Use of the time delay feature will decrease your battery life by approximately 50%. Battery life
will vary depending on the length of the time delay. For instance, batteries will last longer with the
time delay set to 1 minute than with the delay set to 9 minutes.
A time delay is typically used in situations where there is threat of armed robbery. Statistically, an
armed robber will not linger more than a minute or two at a crime scene. The longer he stays,
the greater his risk of being caught. A time delay lock enforces a waiting period which is beyond
the control of either robber or victim.
Whenever a safe is secured with a time delay device, a sign should be posted on the door of
the container to indicate the presence of the device. Suggested wording is:
“THIS EQUIPMENT IS PROTECTED AGAINST HOLD UP AND ROBBERY BY TIME DELAY LOCK.”
A self adhesive label is available from Sargent & Greenleaf distributors or your local safe and lock
retailer. The S&G part number for the label is 0000-636-152000.
TO SET A TIME DELAY . . .
The time delay value can be 1, 2, 3, 4, 5, 6, 7, 8, or 9 minutes. To deactivate the time delay,
set its value to 0 minutes.
Press S G * (______) # 0*(_) # (_) #
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
time delay value is not accepted—the old time delay value is retained.
For instance, if you want to set the time delay to five minutes, use the following procedure.
Press S G * (______) # 0*5# 5#
To turn the time delay off, use the following procedure during the two-minute opening window.
Press S G * (______) # 0*0# 0#

LOW BATTERY CONDITION
The Model 6120 lock uses two 9-volt alkaline batteries. We recommend Duracell®. If the batter-
ies in your lock need to be replaced, twenty consecutive beeps will be heard after the last num-
ber 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 dif-
ferent 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 operation.
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.
STEP 1—Remove the keypad from its mount-
ing base. This can be done by pulling the
bottom of the keypad housing away from the
base. 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 become bent during battery inser-
tion. 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 bat-
tery into it backwards.
(continued on next page)
Step 4—Hold the keypad housing close to
the mounting base while you coil excess
wire inside the housing. 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.
