His face unreadable now, the Satarran replied, "I have destroyed the facility that oversees the habitat's magnetic interlock system."

Destroy the interlock system and the colony itself would quickly follow suit.

The device, called an interlock system, is a small breath analyzer that keeps a car from starting if alcohol is detected.

If he fails to blow sober breath into the so-called interlock system, it will disable the car.

He will then have to use the interlock system to drive for the rest of his three-year probation.

The resultant fuse design was a three-stage interlock system:

The operation of double interlock systems are similar to deluge systems except that automatic sprinklers are used.

Different makes of selsyns, used in interlock systems, have different output voltages.

These requirements can include the use of safety gate switches or trapped key interlock systems.

In high voltage or complex systems, these padlocks may be part of a trapped-key interlock system to ensure proper sequence of operation.
