    • 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.
    • 烟雾探测器验证系统,包括烟雾探测器,便携式计算机系统和光学接收器,验证烟雾探测器的操作。 烟雾探测器包括周期性调制以提供关于烟雾探测器的状态信息的发光二极管(LED)。 便携式计算机系统存储从耦合到便携式计算机系统的光接收器接收的状态信息。 光接收器从LED接收状态信息并将接收的状态信息提供给便携式计算机系统。
