6. Battery Check Procedure:

(voltmeter that can measure 9 v.d.c is required)

Make sure the batteries being used with the lock are marked as

alkaline. “Extra Heavy Duty” batteries are NOT alkaline. Use a

voltmeter to check the voltage level of each battery. Each one

should indicate at least 7.75 volts. If either battery is below this

voltage, replace both with fresh batteries. Fresh batteries will

indicate voltage levels of 9.2 volts or greater.

7. Stop Pin Check and Opening Procedure:

Check: The stop pin is the pin which holds the lock bolt in

the lock. On a few early models it could dislodge and

prevent the drive mechanism from engaging. The

motor can be heard running, but the lock bolt does

not retract. To verify this problem, make sure the

safe boltwork is not binding the lock bolt (see the

information in Step 4). Enter a valid code and listen

to the sound the motor makes. If it makes no sound

at all, the problem is not a dislodged stop pin. If

the motor seems to run normally, wait until it goes

through its retraction and extension cycle (about 6

seconds). Then enter a valid code while pulling the

safe handle toward the unlocked position. If the motor

sounds the same as it did during the previous cycle

(free running), a dislodged stop pin is the most likely

problem.

Opening: If the safe can be moved, the most successful method

is to orient the safe so the lock is in a vertical-up

position (with the lock bolt pointing up). Gravity may

help the drive mechanism engage long enough to

unlock the safe. The lock may need to be operated

two or three times with the safe in this position.

The handle should be tried after each attempt.

If this technique is unsuccessful, drilling is the

remaining option. Contact the safe manufacturer for

recommendations.

8. Keypad Connector Check:

Note: This technique is for standard, two-battery

keypads only.

If the lock works intermittently, check for loose wires at the

keypad connector (underside of the keypad). It is a four-wire

connection. Inspect each wire while pushing it and attempting

to gently rotate the wire where it enters the connector. If any

motion is noted, try pushing in on the wire to attempt to tighten

it. Operate the lock with a valid code. If the looseness is still

present, S&G recommends replacing the lock.

10. Low Battery Warning Check Procedure:

Your lock is equipped with a low battery warning feature that changes

the pitch of the sounder when the batteries need to be replaced. It

also incorporates a low battery tester and warning demonstrator that

simulates the low battery warning signal for one lock cycle. To operate

the demonstrator, press and hold the * key until three beeps are heard.

Now enter a valid code while listening to the sounder. If the sounder

has changed pitch, the batteries are okay (although it is always a good

idea to check them with a voltmeter). If the sounder does not change

pitch, the lock was already in low battery mode when the demonstrator

was engaged, and the batteries should be changed before any further

troubleshooting is attempted.

11. Safe Relock Device Engaged Check Procedure:

It is possible for the safe’s relock device(s) to activate during shipment. If

the safe has recently been serviced or handled roughly during shipment,

the relock device could be engaged. Use the following procedure to verify

this.

A) With the lock in the locked condition, note the amount of

motion in the safe handle

B) Locate the safe handle in the middle of its travel range, and

operate the lock with a valid code

C) As soon as the lock bolt retracts, again note the range of

motion in the safe handle

If the handle moves farther when the lock bolt is retracted, but the safe

does not open, a relock device is probably the cause. The service of a

trained and experienced safe technician should be employed. Contact the

safe manufacturer for recommendations.

The Safe & Vault Technicians Association, based in Dallas,

Texas, can refer you to a safe technician in your area. The

association’s number is (214) 827-7233.
