Study Notes
Fire Alarm Systems
- A conventional fire alarm system consists of various components, including air sampling detectors, smoke detectors, heat detectors, manual pull stations, control panels, supervisory inputs, wall mount control panels, end of lines, annunciators, and trouble devices.
- Advantages of conventional fire alarm systems include lower initial equipment costs, a wide range of compatible devices, ease of programming, and limited expansion capability.
Semi-Addressable Fire Detection and Alarm System
- A semi-addressable fire detection and alarm system combines addressable and conventional detectors to provide more detailed information about the location of a fire.
- The system consists of addressable units, conventional units, zone modules, control modules, and alarm devices.
Automatic Fire Extinguishers
- Automatic fire extinguishers are designed to put out Class A, B, and C fires, involving solids, flammable liquids, and electrical equipment.
- They are ideal for environments where manual operation is not possible, and immediate activation is necessary.
Types of Fire Extinguishers
- Water fire extinguishers are best for Class A fires, involving organic solid materials, but should not be used on burning fat or oil, or electrical appliances.
- Powder fire extinguishers are effective against Class A, B, and C fires, and are suitable for electrical fires.
- CO2 fire extinguishers are best for Class B and C fires, but should not be used on Class A fires.
- Foam fire extinguishers are effective against both Class A and Class B fires, involving solids and flammable liquids.
Backup Power Supply
- A backup power supply is essential in case of a power failure, using 6- or 12-volt batteries to keep the system running.
Addressable Fire Alarm Systems
- Addressable systems display the location of each initiating device on the FACU and annunciator panel, enabling emergency responders to quickly respond to emergencies.
- These systems reduce response time and allow repair personnel to quickly locate and correct malfunctions.
Fire Alarm Components
- Fire notification devices, such as bells, strobes, horns, and chimes, notify building occupants in case of a fire.
- The fire alarm control panel is the central hub of the system, monitoring and managing initiation devices and activating notification devices.
- The primary power supply is typically 120- or 240-volt AC power sources, while the backup power supply provides power in case of a power outage.
