Fire Alarms - Check Out The Latest, Innovative Models!
Fire alarms are another important security device that helps you to
seek protection from fire accidents. Usually fire alarm and fire detectors
are sold as one package.
Fire alarms help raise a loud noise and alerts you as soon as smoke is deducted
by the fire detector. In most cases fire alarm systems act at the
instigation of fire detectors and other devices.
The Purpose of Fire Alarms
A Fire alarm helps you to be protected in case of fire breakouts.
This device is usually made up of electromechanical or other metals
and it will help you to make things better. They create a loud noise
and you will be able to evacuate the building through alternative
and safe passages created already for this purpose. Fire alarms have
helped to save innumerable lives and properties.
Components of a Fire Alarm
Fire alarms are made of many constituents. They can be categorized
into three major units namely control units, fire detectors and alarm
signal devices.
Control Units
The fire alarm system is controlled by a fire alarm control panel.
Like any other security devices this fire control panel can be referred
as the head or brain of the fire alarm signal device. You must primarily
use it to decide how your fire alarm or fire detector should operate.
Besides this there are two more important units. The fire alarm signal
that performs the main function and fire alarm pull station which
transmits signals to the fire alarms through pull boxes.
Fire Detectors
Fire detectors come in two types namely smoke and heat detectors.
Smoke Detectors
Smoke detectors can further be divided into two categories namely
ionization smoke detectors and photo electronic ionization units.
A smoke detector will be helpful to deduct fire even before a fire
breaks out. A smoke detector will therefore be able to
help you in taking preventive actions at an early stage. Photo electronic
ionization detectors can be used in houses while the other category
can be used in offices.
Heat Detectors
Heat detectors also come in two types. They are known as fixed temperature
and rate of rise. In the first type the device will work if the room
temperature reaches an optimal level of 140° F or 195° F.
The other device also works on standard temperature levels. However
they can very well sense sudden and upward fluctuations of temperature.
This device has a limitation when compared with smoke detectors because
heat detectors can only recognize high levels of temperature and it
is difficult to save property or people in most cases.
Alarm Signal Devices
Alarm signal devices are of two categories namely audible and visual.
The first one
Emits loud noise and alerts you to escape from the fire outbreak.
The loud noise may be in the form of bells or speakers or even sirens.
Similarly visuals catch your attention by emitting certain types of
lights like strobe light. It is also possible to intimate the fire
service personnel through the sound.
