Abstract
An adverse condition detect or that allows the user to test the apparatus in close proximity without having to endure full operational alarm activation. The adverse condition detector includes a detector, a transducer and a test system. When the detector senses an adverse condition, the transducer is activated to generate an alarm signal having an alarm level. When the test switch is activated, a test signal is generated at the alarm level and has a test duration that is substantially less than the duration of the alarm signal. In one embodiment of the invention, the alarm signal includes a plurality of alarm pulses having an alarm pulse duration and the test signal includes a plurality of test pulses each having a test pulse duration substantially less than the alarm pulse.
