Abstract
An ambient condition detector includes a time delay function whereby a user initiates a functionality test of the detector and has time to move away from the vicinity of the detector before a potentially hearing damaging, audible report is issued from the detector under test. Multiple ways to set the time delay interval are included in the various embodiments. The sensors of the ambient condition detector may include fire sensors, smoke sensors, gas sensors, motion sensors, vibration sensors and multiple combinations of these sensors.
