• Sargent & Greenleaf 6120 series Motorized Electronic

Combination Locks have been designed to use the same

mounting screw locations and occupy the same space as a

standard S&G 6730 mechanical lock. The 6120 series uses

standard mounting dimensions to simplify retrofit in safes

originally equipped with mechanical locks.

• The keypad base diameter is 4” (101,6 mm). This is slightly

greater than the diameter of standard S&G dial rings for

mechanical locks. The 6120 series keypad will cover any

scratches or paint blemishes left by the old lock.

• Modifications to the lock (including lock bolt attachments)

are not recommended, and will void the manufacturer’s

warranty.

• A minimum distance of .150” (3,8 mm) is required between

the end of the lock case containing the bolt and the safe’s

blocking bar or cam plate which is normally blocked by the

extended lock bolt. This is because the lock bolt may not be

retracted quite as far by older batteries as by fresh ones.

• You should install fresh alkaline batteries in the keypad and

connect the lock wiring cable to check the functions of the

lock prior to installation. Follow the procedures given in the

Operating Instructions. Avoid pressure to the end of the

lock bolt during these checks.

• Do not allow the safe’s blocking bar or cam plate

to depress the electronic lock’s bolt farther than it

retracts during normal motor operation. This can lead to

inconsistent lock operation.
