This document describes a fire alarm and smoke detector system designed using digital logic. The system uses inputs from an emergency switch, smoke detector, and main switch. It outputs a fire alarm and activates an automatic sprinkler system. The logic design includes OR gates, AND gates, a JK flip flop timer set to 3 seconds, a 1Hz clock, 7 segment displays, and inverters. When the smoke detector or emergency switch is activated, the alarm will sound for 3 seconds before automatically shutting off the sprinkler and alarm. The group's responsibilities for the project are also outlined.

- 3. • A fire alarm system is number of devices working together to detect and warn people through visual and audio appliances when smoke, fire, carbon monoxide or other emergencies are present. • Alarms may be activated from smoke detectors, and heat detectors. • A smoke detector is a device that senses smoke, typically as an indicator of fire.
- 4. • Many houses don’t have a fire alarm system so we need to design a fire alarm system using the digital logic system that all family members can use in single-family residences. • It must be able to detect fires at all locations, residents must be able to activate it from convenient locations themselves, and it must alert residents in all portions of the house.
- 5. • To study the working principle of fire alarm and smoke detecting system. • To design, construct and fire alarm system and smoke detector using digital system. • To implement digital logic design in the project. • To discover fires early in their development when time will still be available for the safe evacuation of occupants.
- 6. • Type of Logic • Power Supply • Input • Output Name of Project Fire Alarm & Smoke Detector System Main Functions/Objective To discover fires early in their development when time will still be available for the safe evacuation of occupants. Voltage Supply 5VDC Input Emergency Switch, Smoke Detector and Main Switch. Output Fire Alarm and Automatic Sprinkler Logic Type i. OR Gates ii. AND Gates iii. JK Flip Flop (For timer 3 Seconds) iv. Clock 1Hz Output v. 7 Segment vi. Inverter vii. Indicator
- 8. Switch C is the main switch which is must always be ON in order to activate the whole system. Then, Inputs A&B can trigger the alarm when A OR B is ON. Here the unique of the system, if we switch OFF inputs A&B the timer will ON and count up from 0 to 3 second. After 3 second it will automatically OFF the water sprinkler and alarm.
- 16. • Our project still need to be improve with proper timer reset using the component that has reset on timer so that the system will operate without adding the 2 AND gate as reset/stopper for timer counting. In real situation. • This projects need a lot of addition to be modified such as backup system, including water system and add another indicator for alert surrounding. • We has learn how to be logic in alarm system from this project. This is the basic idea for fire alarm system. For more, the circuit will more complex and bigger than this.
