Abstract
A smoke detector verification system, which includes a smoke detector, a portable computer system and an optical receiver, verifies the operation of the smoke detector. The smoke detector includes a light emitting diode (LED) that is periodically modulated to provide status information about the smoke detector. The portable computer system stores the status information that is received from the optical receiver, which is coupled to the portable computer system. The optical receiver receives the status information from the LED and provides the received status information to the portable computer system.
