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 lock’s 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 is the battery life in S&G’s 6120 and 6123?
During S&G 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.
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.
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.
Does the lock function properly in high humidity conditions?
Yes – S&G’s 6120 design protects the electronic boards with a
coating that shields the lock’s 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.
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.
What is the effect of magnetism on the product?
None—magnetic fields cannot be used to compromise
6120 or 6123 locks as they can with some locks that rely on
solenoid locking devices.
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 is the maximum distance the lock can be located from
the keypad?
The 6120 and 6123 can be supplied with wire lengths up
to 10 feet, at an additional cost. Greater lengths are not
recommended.
How can the 6120 or 6123 be used to retrofit a mechanical
lock that incorporates a wingback cover?
Using longer cover screws, the mechanical lock’s 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.
