315. Bitting position - The location of a key cut
316. Blade - the portion of a key which may contain the cuts and/or millings
317. Blind code - A designation, unrelated to the bitting, assigned to a particular key combination for future reference when additional keys or cylinders may be needed
318. Block master key - The one pin master key for all combinations listed as a block in the standard progression format
3. Time Delay – Used to limit the frequency of opening and to act as a theft deterrent. The delay can typically be set between 1 and 99 minutes.
3. Time Delay Override/Armored Car Override – a specific code is set during the lock initialization that allows the lock to be opened by a forced override during a time delay.
3. Opening Windows – Similar to a time delay, setting opening windows takes the control of opening a step further. Any attempted opening outside of the pre-set time frames are blocked and ignored by the lock. Time frames are customizable, some common utilizations include minutes or seconds following a time delay, or a specific time of day.
3. Wrong Try Penalty – Also referred to as “penalty modes” this feature is available in most electronic locks to prevent an individual from running through various combinations quickly. Following the entry of a number of incorrect codes (the number of incorrect tries can be customized), the lock enters “penalty” or “lock out” mode. Depending on user settings and model, the lock may reset after a set time following the lock out and allow the same number of incorrect code entries, or may require the correct code be entered the first try to prevent re-entry of lockout mode.
3. Dual Custody – This feature prevents a single user from owner the container, typically two entry codes are required for successful opening. Typically given to two separate individuals, dual codes assist in deterring internal theft. The credentials aren’t restricted to multiple codes, they could also include utilization of an electronic lock and a key lock, two separate locks or another method of controlling access.
3. Audits – Most electronic lock manufacturers offer products that allow audit trails to be pulled by authorized individuals with data reports including the number of times the safe was opened, the time of these openings, and the code used for entry. Loss Prevention departments often use these audit trails in internal theft investigations or determining extraction times.
3. Duress Mode – An operating code is entered along with a number or series of number and through the location’s security system or burglar alarm, alerts law enforcement of a robbery in progress. This feature only works when integrated with the alarm system; upon entry of the duress code, the lock is released and the container opened.
3. Ability to Integrate with a Facility’s Access Control System – Allows the ability to interface with the location’s existing access control and alarm system. This feature allows access to audit data in real time, increasing the visibility of who is accessing the safe. Many times this feature will operate in conjunction with the camera in the same room or office as the safe.
