1 EE 294 Master’s Project Spring 2006 D.A.S. Deaf Alert System By Robert Wangai Samer Ashkouri

2 Introduction Build & design a fire alarm alert system for a hearing-impaired person. Build & design a fire alarm alert system for a hearing-impaired person. This system will inform the user of a fire visually and physically. This system will inform the user of a fire visually and physically. As an added feature, a door bell system will be integrated with the fire alarm system to indicate to the user that someone is at the front door. As an added feature, a door bell system will be integrated with the fire alarm system to indicate to the user that someone is at the front door. This system will be monitored through a computer to keep an updated status in case of an emergency. This system will be monitored through a computer to keep an updated status in case of an emergency.

3 4 Major Parts Smoke detector with designed circuit. Smoke detector with designed circuit. Door bell system. Door bell system. Pager like portable device. Pager like portable device. Computer interface board. Computer interface board. All of these parts will use wireless communications to interact with each other… All of these parts will use wireless communications to interact with each other…

4 Smoke detector with designed circuit A communication circuit board was designed to transmit data from the smoke detector to the portable device. A communication circuit board was designed to transmit data from the smoke detector to the portable device. In addition, we integrated a strobe light in this circuit to visually alert the user. In addition, we integrated a strobe light in this circuit to visually alert the user. The smoke detector requires a 9-volt battery to operate. The smoke detector requires a 9-volt battery to operate. The circuit board requires a 9-volt battery to operate. The circuit board requires a 9-volt battery to operate. The strobe light requires 2 AA (3-volt) batteries to operate. The strobe light requires 2 AA (3-volt) batteries to operate. The user will have the option of using either batteries or an AC adapter for their source of power. The user will have the option of using either batteries or an AC adapter for their source of power.

9 Pager like portable device This pager like portable device will act as a receiver and will gather data from the smoke detector & the door bell. This pager like portable device will act as a receiver and will gather data from the smoke detector & the door bell. This portable device alerts the user both physically (by vibration) & visually. This portable device alerts the user both physically (by vibration) & visually. Visually, a red LED light will turn on incase of a fire. In case of the door bell being pressed, a green LED light will turn on. Visually, a red LED light will turn on incase of a fire. In case of the door bell being pressed, a green LED light will turn on. Ideally, this portable device will be worn on the belt or on the wrist of the user. Ideally, this portable device will be worn on the belt or on the wrist of the user.

10 Pager like portable device circuit

11 Computer interface board A communication circuit board was designed to receive data from the smoke detector and the door bell device. A communication circuit board was designed to receive data from the smoke detector and the door bell device. In addition, it will monitor alarms through an RS pin cable connection to a computer. In addition, it will monitor alarms through an RS pin cable connection to a computer. An AC adapter will be needed to help power this device. An AC adapter will be needed to help power this device.

16 Deaf Alert System

17 Conclusion The Deaf Alert System will be used as an early warning system incase of a fire emergency. The Deaf Alert System will be used as an early warning system incase of a fire emergency. It will additionally help the user find out when someone is at the front door. It will additionally help the user find out when someone is at the front door. Finally, this system will keep an updated status and monitor any kind of alarm on the user’s personal computer. Finally, this system will keep an updated status and monitor any kind of alarm on the user’s personal computer.
