Patent ID: 8477042

Claim:
An extension loop alarm notification output arrangement for use in a safety notification system, comprising: a notification extension loop connected to the safety notification system that generates an alarm notification output signal, configurable into a first and second wiring configurations of a notification appliance circuit; wherein the notification extension loop comprising: first, second, third and fourth outputs of the notification extension loop configurable for the first and second wiring configurations of the notification appliance circuit; at least two of configurable terminals having first and second configurations corresponding to the first and second wiring configurations, the first configuration configured to connect the first, second, third, and fourth outputs to one notification appliance circuit, and the second configuration configured to connect the first, second, third, and fourth outputs to two notification appliance circuits; an end-of-line resistor of the notification extension loop, wherein said end-of-line resistor configured to couple between the at least two of configurable terminals; and wherein the at least two of the configurable terminals in the first configuration couples said end-of-line resistor between the third and fourth outputs, and wherein the at least two of the configurable terminals in the second configuration decouples said end-of-line resistor from the third and fourth outputs.
