Adverse condition detector with diagnostics

摘要

An adverse condition detector that records historical data concerning the operation of the detector such that the detector can be interrogated by a technician. The microprocessor of the adverse condition detector monitors for alarm conditions and other important information related to the operation of the detector. Upon identifying an important characteristic of the detector operation, the microprocessor time stamps the information and stores the information within memory of the microprocessor. The detector includes an interface pad that is accessible from the exterior of the detector such that a technician can access the interface pad without removing the detector housing.
