Multifunction smoke alarm unit
First Claim
1. A multifunction smoke alarm unit comprising:
- a single enclosure that approximates the size of a smoke detector configured for installation on a ceiling or wall;
at least two separate sensors located within said single enclosure, wherein at least one of said sensors is a smoke or combustion detector, and at least one of said sensors is an occupancy sensor that detects the presence and absence of occupants;
said at least two separate sensors are powered externally from an AC source;
said at least two separate sensors further includes a battery to provide power in the event of AC power disruption;
further includes at least one hard wired interconnect which can connect to at least one other smoke alarm or multifunction smoke alarm unit;
said interconnect link(s) provides propagation of smoke alarms, occupancy alarms and signal events to at least a second smoke alarm and or multifunction smoke alarm, andat least one audible warning device for notification of a-combustion or an occupancy or vacancy detection event.

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

33. A multifunction smoke alarm unit comprising:
-
a single enclosure that approximates the size of a smoke detector configured for installation on a ceiling or wall; at least two separate sensors located within said single enclosure, wherein at least one of said sensors is a smoke or combustion detector, and at least one said sensors is an occupancy sensor; one or more communication link(s) which can connect to at least one other smoke alarm unit, multifunction smoke alarm unit, network, computer network, external lighting, HVAC system, HVAC thermostat, ceiling fan, ventilation system, security alarm, and or fire safety system; at least one audible warning device for notification of a combustion or a motion detection event; functions as a smoke alarm in accordance with NFPA 72 National Fire Alarm code industry standard smoke alarm building codes, and functions as an intruder alarm, visitor annunciator, occupancy-based automatic night light with integrated illumination source, automatic security light controller, occupancy-based external lighting controller, occupancy-based HVAC system controller, occupancy-based ceiling fan controller, occupancy-based ventilation controller, and/or occupancy-based fire safety system controller.
