A combination lock with a holdup delay requires the user to wait a predetermined time (4 to 30 minutes, but usually 15) after dialing the combination before the safe door can be opened. After this delay period, there is a grace period of 2 to 3 minutes during which the user must make the final bolt-retracting turn of the safe dial. If this is not done in time, the entire dial-and-wait process must be repeated. Many businesses use these devices and advertise their use, as a deterrent. However, improperly placed or used, these devices can actually increase risks. If employees are inattentive, anyone can gain easy access to the safe contents during the grace period. If the safe is open to public scrutiny, potential robbers can observe the safe-opening routine and use the information thus gained to plan their crime. Risks associated with these devices, however, can be reduced or eliminated: (1) the safe should be kept out of public scrutiny, (2) business personnel should not provide clues on the delay period, or (3) two safes can be used -- one easily accessible and convenient and a secondary safe with a delay timer that is kept in an area not visible or accessible to unauthorized personnel.
