Abstract
A smoke alarm device including self-test reminder circuitry is provided. The smoke alarm includes smoke detection circuitry and a smoke sensor, the functionality of which may be tested using a test switch connected in parallel across the smoke sensor. Additionally, a reminder circuit is provided, the output of which may be used to enable an indicator. The indicator may be the horn or annunciator of the smoke detector, or may be some other type of indicator, such as a light or other audible indicator. Periodically, the reminder circuit will cause the indicator to become enabled so as to remind the consumer to test the smoke alarm. The indicator will remain enabled until the reminder circuit is manually reset by the consumer. Actuation of the test switch simultaneously tests the functionality of the smoke detection circuitry and resets the reminder circuit.
