Multiple suite audio line isolator

1. A method for isolating suites comprising the steps of:

isolating the suites when an alarm is initiated;

setting a timer during isolation creating a window of time to clear a short circuit;

clearing said short circuit;

removing isolation from the suites as the timer reaches completion;

determining if there is a short circuit in each of the suites;

isolating suites that have a short; and

determining if there was an audio short before said alarm was initiated.

2. The method as recited in claim 1 further comprising the step of supplying the suites with supply power through a single power supply path when said alarm is initiated.

3. The method as recited in claim 1 further comprising the step of determining if a short circuit was present before said alarm was initiated.

4. The method as recited in claim 3 further comprising the step of disabling audio if a short circuit was present before said alarm was initiated.

5. The method as recited in claim 1 further comprising the step of providing supply power to the suites in series before said alarm is initiated and providing supply power to the suits in parallel after said alarm is initiated.

6. The method as recited in claim 1 further comprising the step of using a resistor to determine if there is a short circuit in each of the suites after the timer has timed out.

7. The method as recited in claim 1 further comprising the step of using a resistor to determine if there is an audio short circuit in each of the suites after the timer has timed out.

8. A line isolator for multiple suites comprising:

a supervisory relay capable of supplying power to suites in series and in parallel;

an isolation relay in communication with said supervisory relay wherein said isolation relay prevents power from being supplied to a suite;

sense circuitry in communication with said isolation relay wherein said sense circuitry determines if there is a short circuit;

latching circuitry in communication with said sense circuitry wherein said latching circuitry activates said isolation relay to prevent power from being supplied to a suite when said sense circuitry determines the occurrence of a short circuit; and

a timer in communication with said latching circuitry wherein said timer allows time for a short circuit to be cleared during isolation, wherein, upon completion of said isolation relay activation, the isolation is independent of audio used to sense the short circuit.
