摘要：
A method for testing smoke sensor is to set a predetermined level for alarm generation on the basis of information on a first output of a main light receiving element for a stray light caused by an emitted light from a main light emitting element, a second output of an auxiliary light receiving element for the emitted light directly received from the main light emitting element and a composite output of the first and second output whereby tests for confirming normal operation and the like of the smoke detector can be executed with high precision.
