| Summary: | The design of a flre alarm system for deaf and hearing impaired persons using remote and multiple sensing devices is presented in this thesis. The function of this device is to inform the hearing impaired persons to the occurrence of a fire especially while they are in deep sleep. It is designed to be effective, reliable, relatively inexpensive and to avoid any necessity for direct connection to the user. The system consists of a transmitter unit which may be connected to almost every existing fire alarm system and transmits an on/off signal by radio frequency to a portable receiver(vibrating unit) which will trigger a vibrating device and flashing light indicator used by the deaf person. In addition a sleeping cot vibration or heating element will be incorporated to the device. With suitable modification, this device can also be used as a burglar alarm and to monitor door bell, telephone ringing, alarm clock, etc, thus making it a versatile system. |
