Are the 6120 and 6123 manipulation-resistant? Yes—traditionally manipulation techniques are ineffective on the 6120 and 6123 locks. They are also designed to resist random code input by locking out for up to 15 minutes after incorrect codes are entered. Both the 6120 and 6123 are UL Type 1 Listed.
Can the audible beep, which confirms code input, be adjusted or mounted remotely to an external sounding device? Yes—a remote indicator became available in 1996 with a count-up or countdown display, LED, and a remote sounder.
Can the lock replace a standard mechanical lock? The 6120 and 6123 mounting holes, bolt placement and throw are identical to a 6730 combination lock. The case dimensions are equal except for the thickness of the lock body, which is .044” greater than the 6730.
Does the lock function properly in high humidity conditions? Yes – S&aGs 6120 design protects the electronic boards with a coating that shields the locks electronic components from the effects of humidity. Locks have been tested in uncured fire safes for a 90-day period and shipped cross-country without incident, and they continued to function properly.
Does the lock have a duress mode? For duress, use one of the following lock models: 6124, 6125, 6126, 6127, 6128, 6129, or 6150.
Has the 6120 been tested for electromagnetic interference (EMI), and static electricity? Yes—under stun gun attacks, the 6120 fails secure. Locks produced after March, 1995 provide ground paths that allow static electricity to dissipate into the safe body, preventing circuit damage. In the first quarter of 1996, a ground circuit was also added to the keypad.
How can the 6120 or 6123 be used to retrofit a mechanical lock that incorporates a wingback cover? Using longer cover screws, the mechanical locks wingback cover can be fastened directly on top of the 6120 or 6123 lock cover. Before doing this, use a file or grinder to remove any projections from the underside of the wingback cover.
How do I change the Master Code? Press 74*. Press the six digits of your code, followed by #. Wait for the lock to beep 5 times. Press 1*. Press the six digits of your new code, followed by #. Wait for the lock to beep 3 times. Again press the six digits of your new code, followed by #. The lock will again beep 3 times.
How do I know that the code changed? If your lock emits a continuous tone for about one second anytime during the code changing procedure, you have made an error. When this happens, the lock ignores your new code and reverts to the old one. For more detailed changing instructions, see the complete version of the operating instructions.
How far does the lock bolt retract? Under normal operation, the bolt retracts at least .375”, leaving no more than .109” extended (our installation requirements are .150”, case to boltwork). These are the same dimensions as the standard bolt of the 6730 mechanical combination lock. Lock bolt retraction is dependent on battery condition.
How long does the bolt stay retracted after code entry? The bolt retracts for 6 seconds, allowing sufficient time to turn the safes handle.
How should the lock be mounted? Either lock can be mounted in any position, including the standard positions of right-hand, left-hand, vertical-up, and vertical-down.
If my keypad is taken and the lock cable cut, how can I get in my safe? A qualified safe technician can temporarily attach a new keypad and cable section and use your code to open the safe. Once the safe is open, the lock body (and attached cable) should be replaced.
If user codes and time delay are entered through a Master Code, what happens to the user codes and time delay if the Master Code is changed? Nothing, because a Master Code is only a means to implement the change procedure for user codes or time delays. For the 6123, it can also set the mode of lock operation, time delay window duration, and set the time delay override code.
Is the 6120/6123 a unique S&G design? Yes—the electronics, motor, and all other component parts are unique S&aG designs. S&aG has a license arrangement with another company to assure there are no infringements on existing patents.
Is there a recommended procedure for installing batteries in standard, two-battery keypads? Yes – install new batteries by pushing them directly into the battery connectors attached to the keypad circuit board. It is important to support the connectors so they are not bent due to excessive force.
What are the service or maintenance requirements for the 6120 and 6123? Due to the design, substantiated by S&aG testing, no service is needed, even in harsh environments. S&aG laboratory testing consistently exceeded 500,000 opening cycles without problems. Changing the batteries is the only service required.
What happens if carbon batteries are used rather than the recommended alkaline batteries? Carbon batteries do not allow as much current draw as alkaline batteries, and even new carbon batteries will not retract the bolt sufficiently for frequent openings. So, be sure to use alkaline batteries, preferably Duracell brand.
What happens if someone takes my keypad. Can they determine my code(s): The keypad is a “dumb” input terminal. Your codes and security information are stored in the lock body, inside the safe. No one can steal your codes by taking the keypad. To operate your lock, simply plug in a new keypad.
What happens if the batteries go dead? Are the codes lost? How long will the electronics remember the codes? Codes will be retained in the locks electronic processor for up to 10 years, even if batteries are removed or go dead. Batteries are easily replaced by removing the keypad housing.
What happens to the lock when there is a bolt side pressure from the safe’s boltwork? The boltwork of a safe, under certain conditions, can place excessive pressure on the side of any locks bolt. When this occurs, the locks bolt cannot retract properly. To relieve side pressure on the lock bolt, jiggle the safes handle. This action will remove the pressure on the locks bolt. Then re-enter a valid code to open the safe. No damage occurs to the lock under these circumstances.
What happens when the 6120 or 6123 lock is electronically attacked? If attacked with low voltage, the lock is not affected. If high voltage is applied, the lock is designed to fail secure (the lock remains closed). Therefore, attempts to defeat the lock will be unsuccessful. After an attack with high voltages, some electrical components could be damaged and may require lock replacement.
What if the master code and user codes are forgotten? S&aG recommends ordering locks with the management reset code (MRC) option. This allows the lock to be reset to the factory master code setting (1,2,3,4,5,6 #).
What is the battery life in S&Gs 6120 and 6123? During S&aG accelerated laboratory testing, which is more demanding on batteries than daily normal use, we routinely exceeded 8,000 opening and closing cycles using Duracell 9-volt alkaline batteries.
