Model 2740 High-Security Electromechanical Safe Lock
• Approved for installation on all classes of GSA-approved security containers.
• Powered by a readily-available, long-life CR123A camera-type battery, with a CR2450 backup battery.
• Built in low battery indicator gives 100 obvious low battery warnings before the backup battery engages.
• Battery life has been tested in excess of 20,000 openings and closings.
• New design motor-driven lock mechanism offers a high level of security by eliminating the threat of vibration and bouncing attacks.
• Penalty Time feature prevents opening by entering sequential or random combinations until a valid combination is found.
• Familiar left-right-left dialing sequence is natural for those users who are already accustomed to using mechanical locks.
• No hard-to-read LCDs or confusing display icons or symbols to interpret.
• Single control and dual control modes.
• Built in relock trigger and thermal relock component for resistance to forced and covert entry attempts.
• Stainless steel lock bolt resists 600 lbs of end and side load.
• Bolt retracts flush with the end of the lock case and travels .461 inch, eliminating the need for an optional short bolt for Mosler retrofits.
• Bolt is drilled and tapped to accept most bolt extensions used in GSA containers.
• Simplified installation makes this the fastest, easiest to install lock in its category. A single brass spindle connects the dial to the lock. No
tubes to cut and deburr, and no delicate cables to contend with.
• Uses S&G’s “Magic Module” footprint, the standard of the industry, for ease of retrofit.
• Lock cover is retained unless the lock bolt is extended, eliminating the possibility of the safe or vault door being closed while the cover is
removed from the lock.
