Fire protection system with fan shut off, including a camera and a display unit
The invention relates to system for suppressing the fire and warning to the occupants are disclosed. The described system includes a thermostat and Fan in an HVAC interface with a residential HVAC system, a receiver operable to receive a signal indicating the presence of a fire or smoke, and a processor in communication with the receiver and in response, sends a signal to the HVAC interface to cause the residential HVAC system to be shut down. In addition the system also includes camera system sending signal to a display unit displaying the floor and room number on the screen, thus warning the occupants the location of the fire.
1. A system for suppressing fire in a building, the system comprising:
a plurality of smoke detector units,
each smoke detector unit comprising:
a smoke detector,
a power supply,
an auxiliary power supply,
a camera connected to the smoke detector, and
a wireless transmission unit connected to the camera
a normally closed relay,
a fan controller connected to an HVAC unit,
a thermostat,
a display unit,
a micro-controller for display unit,
a wireless receiver for the micro-controller,
a telephone system,
wherein upon detection of a smoke by any one of the smoke detectors, the respective smoke detector passes a signal to a normally closed relay to open and to cut-off the power supply to the thermostat as well as fan controller thereby shutting off the fan unit; and activates the respective camera and the wireless transmission unit to transmit a signal to a wireless receiver connected to the micro-controller so as to display the location of the fire on the display unit connected to the micro-controller.
2. The system of claim 1 , wherein said building comprises more than one fire zone.
3. The system of claim 1 , wherein said telephone system is adapted to call fire department.
4. A system for suppressing fire in a building, the system comprising:
a plurality of smoke detector units,
each smoke detector unit comprising:
a smoke detector,
a wireless transmission unit connected to the smoke detector,
a power supply,
an auxiliary power supply,
a camera connected to the smoke detector, and
a wireless transmission unit connected to the camera,
a normally closed relay,
a fan controller connected to an HVAC unit,
a wireless transmission unit connected to the relay,
a thermostat,
a display unit,
a micro-controller for display unit,
a wireless receiver for the micro-controller,
a telephone system,
wherein upon detection of a smoke by any one of the smoke detectors, the respective wireless transmission unit connected to the smoke detector passes a signal to a normally closed relay to open and to cut-off the power supply to the thermostat as well as fan controller thereby shutting off the fan unit; and activates the respective camera and the wireless transmission unit to transmit a signal to a wireless receiver connected to the micro-controller so as to display the location of the fire on the display unit connected to the micro-controller.
