Model 6123—Motorized Electronic Combination Lock

decisions —mrc And tdo

mrc—mAnAgement reset code

Before any buttons are pressed, you need to make some decisions.

The first is whether or not your lock is to have a management reset

code, also known as the MRC. This code must be programmed into

the lock before the master code is changed for the first time. After

the master code is changed, the lock can never be programmed with

an MRC. Conversely, when an MRC is programmed into a lock, it is

always present. It cannot be deleted or changed.

Some 6123 locks have factory installed management reset codes,

depending on how they were ordered by the safe maker or dealer. You

cannot install a new MRC to replace an existing one.

The management reset code is used to regain control of a lock when

its master code is lost. When the MRC is employed, it deletes the

supervisor and all user codes present in the lock and changes the

master code to the factory default of 1 2 3 4 5 6 #. While this can

be a real time and money saving feature if a master code is lost,

the presence of a management reset code in a lock could also be

viewed as a security weakness under some circumstances. Carefully

consider whether or not you want to program an MRC into you lock. If

you decide to use this feature, here’s what you need to know.

Important: All programming and code changing should be

done with the safe door open. Do not close the safe door until

all programming and/or code changes are completed and triple

checked to make sure everything is working correctly.

An MRC consists of seven digits, including one [01] or [03] pair

that can appear once anywhere in the code. When entering the

MRC, these two digits are pressed simultaneously. An example of an

acceptable management reset code is:

7 4 8 1 [1 0] 5

Before programming the MRC into the lock, enter the master code

(123456#) to make sure the lock is functioning correctly on the

factory default master code. When the bolt extends, press:

* *

# 1 2 3 4 5 6 #

(______) # (______) #



The [01] or [03] pair of digits in your management reset code must

be pressed at the same time. The lock will emit three rapid beeps

after the final # is pressed to acknowledge successful programming

of the MRC. If you don’t hear those three beeps, the MRC has not

been programmed. If you hear a long tone (called a “brap”) while

trying to program the MRC, either you’ve made an error in the entry

sequence, the lock already has an MRC, or the master code has

been changed. Even if the master code is changed, then set back to

1 2 3 4 5 6 #, the management reset code cannot be set.

The procedure for using the management reset code to reset a lock

with a lost master code is found later in the manual.

tdo—time delAy override

Note: Time delay override is not available if the lock is used in

supervisor/user mode.

If your 6123 will be using a time delay, you may also want to program

a time delay override capability. Like the MRC, you’ve got to make

this decision and do the programming before the master code is

changed for the first time.

A time delay is used to deter armed robbery. Statistics show

that the longer an armed robber has to wait for a safe to open,

the less likely he is to initiate the crime. The 6123‘s time delay

feature enforces a waiting time between the entry of the lock

code and the opening of the safe.

Often a safe that requires a time delay lock is involved in a cash

carrier or armored car pickup process. Excess cash receipts

are picked up at various intervals by armored car services.

In the interest of security and efficiency, it is important that

these couriers do not spend any more time than is absolutely

necessary to access the safe, remove the excess valuables, and

be on their way. This is where the time delay override code

comes into play. It allows one code to override the lock’s time

delay and open the safe immediately.

Before the lock’s master code is changed for the first time,

you should determine whether or not you will need a time delay

override code or not. If you will need a TDO, you must decide

if it will be a single user time delay override or a dual control

time delay override.
