Abstract

A wiring harness for a fire extinguishing system including a connector that has a pair of power leads and a pair of command leads. At least one zone identification element is in communication with the connector and is configured to provide a zone location assignment to the connector.

Claims

1. A fire extinguishing system comprising:

a wiring harness including;

a connector having a pair of power leads and a pair of command leads; and

at least one zone identification element built into the wiring harness and in communication with the connector and configured to provide a zone identification assignment to the connector;

a component connected to the connector, the component includes a microprocessor configured to interpret the zone identification assignment and establish a zone location in response thereto; and

a controller connected to the wiring harness and configured to receive the zone location from the component.

2. The system according to claim 1, wherein the zone identification element is a resistor corresponding to the zone location assignment.

3. The system according to claim 1, wherein the zone identification element is at least one pin providing a binary number corresponding to the zone location assignment.

4. The system according to claim 1, wherein the component is a detector connected to the connector, the detector taking the zone location assignment.

5. The system according to claim 1, wherein the component is a suppressor connected to the connector, the suppressor taking the zone location assignment.

6. The system according to claim 1, comprising a zone, the zone including multiple connectors having zone identification elements corresponding to the same zone location assignment.

7. The system according to claim 1, wherein the wiring harness is configured to be connected to an external device.

8. The system according to claim 7, wherein the external device is one of a detector, a suppressor, and a fire extinguishing activation module.
