    摘要: A low current drain timer for bank vaults is easily settable to limit opening of the vault to a predetermined time, irrespective of the time of closing the vault. Three thumb wheels having corresponding indicia are set to designate the elapsed time necessary for reopening. A timer is activated by a reset switch and the manual repositioning of a mechanical latch, which latch permits later closure of a vault door. Either of sequentially operating solenoids at the lapsed time permit opening of the vault door. A backup battery power source renders the timer unaffected by failure of a conventional electrical power source.
