摘要: Improvements in a smoke alarm are presented. The multifunction unit includes separate sensors within single enclosure for detecting and occupancy, sounding distinctive audible when combustion is detected or the presence of person area sensor. can replace an existing function alarm. Multiple alarms networkable together various purposes. Additional features include intruder alarm, visitor annunciator, integrated illumination source, external lighting control, HVAC system ceiling fan ventilation and/or fire safety control. proposed provides much-needed improvements security, energy saving, safety, user convenience without need completely systems each purpose.
