CONVENTIONAL FIRE ALARM PANEL SYSTEM TO CONTROL FIRE
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. These alarms may be activated
from smoke detectors, and heat detectors. Alarms can be either motorised bells
or wall mountable sounders or horns. They can also be speaker strobes which
sound an alarm, followed by a voice evacuation message which warn people
inside the building not to use the elevators. They may also be activated
via manual fire alarm activation devices such as manual call points or pull
stations. Fire alarm sounders can be set to certain frequencies and different
tones including low, medium and high, depending on the country and manufacturer
of the device. Most fire alarm systems in Europe sound like a siren with alternating
frequencies. Fire alarm sounders in the United States and Canada can be either
continuous or set to different codes such as Code 3. Fire alarm warning devices
can also be set to different volume levels. Smaller buildings may have the alarm
set to a lower volume and larger buildings may have alarms set to a higher level.
Fire alarm control panel (FACP) AKA fire alarm control unit (FACU); This component,
the hub of the system, monitors inputs and system integrity, controls outputs and relays information.
After the fire protection goals are established – usually by referencing the minimum levels of
protection mandated by the appropriate model building code, insurance agencies, and other authorities – the
fire alarm designer undertakes to detail specific components, arrangements, and interfaces necessary
to accomplish these goals. Equipment
