The Sargent & Greenleaf model 2740 lock was designed to meet Federal Specification FF-L-2740A. It can be easily retrofit to most security containers currently in service.
It is necessary to remove only the lock cover for installation. All other parts should remain in place as received from the manufacturer.
Most safes and cabinets will already be prepped for lock installation. In the unlikely event that this is not the case, locate exact position you want for the lock on the mounting plate. Use the template on the last page of the instructions.
Wear the included static discharge wrist strap whenever you are about to remove the lock cover, or whenever the cover is off of the lock body. The strap should be grounded to any bare metal of the container. It is also recommended that you lay the cover (still in its protective sleeve) on the container, then touch the container prior to handling the cover. This should reduce the possibility of static discharge.
It is necessary to remove only the cover when attaching the lock. All other parts should remain in place as received from the factory. When the cover is off of the lock, handle it carefully. It houses the microprocessor and related circuitry. Do not touch the circuit board.
