• The S&G Model 2740 Electromechanical Safe Lock is shipped
©
from the factory in single user mode with a factory shipping
combination of 50-25-50. This combination is used to open
the lock and change the combination(s). It is also used in
conjunction with the setup module to access the lock for
calibration, setup, and maintenance. You should set the lock
to your own, unique combination(s) before storing anything of
value in the safe or cabinet.
• All setup, maintenance, and troubleshooting operations must
be performed with the safe or container OPEN. Never close
the container with either a change key or the setup
module attached. At the conclusion of a combination change
or service operation the lock should be checked to make sure
it operates at least three times consecutively on the intended
combination before closing the safe or container. The setup
module must be disconnected to test the lock.
• The lock will sometimes emit a beep or series of beeps to
communicate its state. A table of the eleven possible beep
patterns is included in this document (page 12).
• All combinations must contain three numbers, ranging from
0 to 99. Unlike mechanical locks, the 2740 has no forbidden
zone, and it does not have a restriction on how close adjacent
numbers of the combination may be to one another.
• If you stop dialing for more than ten seconds, the lock will
reset, forcing you to begin the combination entry sequence all
over again.
• If ten incorrect combinations are entered in a row, the S&G
Model 2740 Electromechanical Safe Lock will shut

Lock is powered by a main battery (CR123A lithium
camera-type), and also uses a long-life backup battery
(CR2450 coin cell). Both batteries must be changed at the
same time by a technician who has successfully completed
S&G factory approved training.
• The 2740 will switch to the backup battery and latch OPEN if
the ten-beep low battery signal is repeatedly ignored. Opening
with the backup battery may take as long as five seconds
after the combination is entered. If you find that your lock
will not lock, the batteries will have to be replaced, and it will
need to be reset by an S&G 2740 Certified Technician using a
setup module.
• The lock's combination can be changed by use of the setup
module or a separate change key. Only a safe technician who
has successfully completed the factory approved 2740 training
class should connect a setup module to a lock. The change key
can be used by a safe custodian or security officer following
the appropriate instructions included in this document.
• Lock bodies and covers are matched components. Do not
replace a lock cover with the cover from another lock. At best,

this will produce erratic lock operation.
