Abstract
Optically isolated input circuits and a processor interface with either a switch closure event detector or a pulse generator to rapidly detect changes in the status of inputs representing events such as telephone line cuts and emergency conditions. The processor determines telephone line status by applying software algorithms to data acquired with a voltage sampling circuit. The processor initializes a radio module to wirelessly transmit information regarding detected events over a local wireless system to an event clearinghouse.
