A network lock system and a method for operating the network lock system. The network lock system includes a lock mechanism and a device adapter for applying a power signal to a lock mechanism in which a bolt and a latch are locked together. The lock mechanism includes an electromagnet and a compressible spring. The power signal provides power to the electromagnet which causes the bolt to be attracted into the electromagnet by an electromagnetic force exceeding a compression force of a spring which causes the bolt to be released from the latch and causes the bolt to be surrounded by the electromagnet. Withdrawing the power signal from the lock mechanism removes the power provided to the lock mechanism which removes the electromagnetic force resulting in the compression force of the spring pushing the bolt into the latch causing the bolt and the latch to be locked together.
