Time-delay Combination Locks
A time-delay combination lock is most commonly a digital, electronic combination lock equipped with a delay timer that delays the unlocking of the lock by a user definable delay period, usually less than one hour. Unlike the time lock, which unlocks at a preset time (as in the case of a bank vault), time-delay locks operate each time the safe is unlocked, but the operator must wait for the set delay period to elapse before the lock can be opened.

Famous quotes containing the words combination and/or locks:
“Nature is an endless combination and repetition of a very few laws. She hums the old well-known air through innumerable variations.”
—Ralph Waldo Emerson (18031882)
“So Lycidas sunk low, but mounted high
Through the dear might of him that walkd the waves,
Where other groves and other streams along
With nectar pure his oozy locks he laves
And hears the unexpressive nuptial song
In the blessd kingdoms meek of joy and love.
There entertain him all the saints above
In solemn troops and sweet societies,
That sing, and singing in their glory move,
And wipe the tears for ever from his eyes.”
—John Milton (16081674)
