ENVIRONMENTAL CONDITION DETECTOR TRANSMITTER INTERFACE

摘要

A transmitter interface board (12) for integration with a conventional environmental condition detector (16) (such as a smoke detector, carbon monoxide detector, etc.), for transmitting information on the operating status of the detector to a remotely located monitoring facility (20). The transmitter interface is connected to a detector circuit (16) in the condition detector in a manner such that the interface can detect alarm pulses emitted from the detector. Based on the number of alarm pulses emitted in a pre-defined interval the tranmsitter interface is able to determine the operating status of the detector. The operating status information is then sent by a transmitter (64) to the central monitoring facility.
