Abstract
The pitch of tones within tonal patterns emitted by ambient condition detector units and systems in the alarm or testing state is not always optimum to be heard by a wide range of users. An ambient condition detector outputs an alarm comprising a tonal pattern whereby a user can select at least one pitch tone emitted within a tonal pattern alarm when the detector senses an ambient condition. Options include verbal output.
