Abstract
The Uninterruptible Timed Electromagnetic Locking mechanism consists of a rechargeable DC battery pack wired in parallel downstream of the power supply, a logic circuit including a programmable timer relay which when activated by a switch, engages the lock for a user-set amount of time regardless of future switch states, and an electromagnetic lock controlled by the logic circuit and programmable timer relay.
Claims1
An uninterruptible timed electronic locking circuit comprising:
- a. A circuit power source consisting of an AC-DC power supply whose output is wired in parallel with a rechargeable DC battery pack, and
- b. A logic circuit consisting of a switch, NAND gates and a programmable timer relay connected immediately downstream of the circuit power source, and
- c. An electromagnetic lock connected immediately downstream of the logic circuit,
- Whereby the electromagnetic lock will engage and remain engaged when a user first turns on an input switch, regardless of future switch inputs, until the set time value of the user-programmable timer relay expires, and
- Whereby the normal operation of the logic circuit and electromagnetic lock are not compromised by a loss of power at the input of the AC-DC power supply due to the rechargeable DC battery pack wired in parallel with the output of said AC-DC power supply.
