Adverse condition detection and notification apparatus

The present invention provides an adverse condition detection apparatus that enables a user to test the apparatus in close proximity without having to endure fully operational alarm noise. In one embodiment, the apparatus includes a detector, a transducer, and a test system. The detector provides an adverse condition signal in response to detecting an adverse condition (e.g., smoke). The transducer is operably connected to the detector for receiving the adverse condition signal. The transducer generates an operational alarm in response to receiving the adverse condition signal when the detector detects the adverse condition. The test system is operably connected to the transducer and causes it to generate a test alarm in response to a user activating the test system. However, the test alarm, at least initially, is lower in audibility than the operational alarm.
