Sargent and Greenleaf 6120 Troubleshooting Manual

Model 6120, 6123
Motorized Electronic
Combination Locks
This troubleshooting guide is designed to help you identify and solve problems you may encounter with
a Sargent & Greenleaf electronic lock. It is not designed as a substitute for the instructions that were
shipped with your lock. If the instructions are missing, you can obtain a replacement by contacting S&G
at the Nicholasville address listed at the bottom of the page. As an alternative, you can call us at (859)
885-9411. An automated literature extension will record your request and mailing information. An auto-
mated lock help line is also available 24 hours a day, 7 days a week. The number is (800) 826-7652,
extension 500. You must call from a touch tone phone. Troubleshooting information is also available on
S&G's internet site. The address is www.sargentandgreenleaf.com.
Some of the following troubleshooting procedures are intended for the consumer, and others require the
skills of a qualified safe technician. The Sargent & Greenleaf line of electronic combination locks is not
designed to be user serviceable. We specifically do not recommend any repairs beyond replacing either
the keypad or the lock body as a unit.
All applicable troubleshooting procedures should be tried before a safe is forcibly opened. Whenever a
safe must be opened by drilling, S&G recommends you contact the safe manufacturer first. The safe
maker will supply appropriate procedures for dealing with his product.
If you find it necessary to locate a competent safe technician in your area, S&G suggests you call the Safe
& Vault Technicians Association, at (214) 827-7233. Any work which you think may be submitted to S&G
as a warranty claim must be cleared by our Technical Services Department prior to completion.
Basic Operation:
The Sargent & Greenleaf line of electronic locks is powered by alkaline batteries which are
located under or within the keypad housing. They can be easily replaced by following the
instructions that originally came with the lock.
The lock can be ordered in two basic lock bolt configurations—a traditional square bolt for
use with most safe designs, and a beveled spring bolt for direct locking applications on
light safe doors and inner compartments of burglary safes.
When the correct code is entered and followed by the # sign, a motor retracts the lock
bolt. This allows the container to be opened. The bolt remains retracted for six seconds;
then the motor extends the bolt again. S&G electronic locks are equipped with a spring
mechanism to automatically extend the bolt after any obstruction, such as safe boltwork,
is moved out of its path.
Some safe manufacturers ship safes with the lock bolt retracted. With the door open and
the safe handle turned fully to the locked position, enter the code (followed by the # sign).
Wait fifteen seconds, then repeat the procedure. The lock should now cycle normally.
Close your safe door only after checking for proper lock operation at least three times.
