Automatic fire alarm systems are fairly common today. Most homes, businesses and commercial complexes have installed these alarm systems to safeguard themselves against fire and its adverse affects on life and property. These systems generally consist of a series of devices that act in tandem to avert a fire or damage caused by fire.
All such systems have a basic device called the initiating device that detects the advent of fire or other signals like smoke in the air. These devices can detect fire through a rise in temperature or through smoke particles that fill the air around these devices. Other than the initiating device’s basic function of alerting about a fire, modern equipments also have recording facilities to enable monitoring.
The alarms are the other parts of the set up and these are triggered off as the initiating device detects some problem. Generally most detectors themselves can sound a beep but it can go unheard if no one is around. Hence, it is always wise to invest in alarms that ring loudly to alert all occupants of a building or home.
These devices are connected through a set of wiring that runs from a central outlet to control all devices. Some basic alarms also come with battery operated instruments and they do not require wiring. However, if your building is still under construction, it is always wise to plan such wiring requirements and install them during the construction itself.
The central device that controls all these devices is called the control panel. A wire runs from the control panel to connect all devices. In good systems, the wire comes back to the panel and creates a loop through which individual devices can send and receive signals from the control panel. It makes the process of recording system performance much easier.
Working of an Automatic Fire Alarm System
With all the devices explained above, a fire alarm system works to protect life and property. A signal is sent by the detectors or the initiating devices to the control panels. These devices have a simple mechanism in which they trip to send a signal. As the control panel receives the signal, it sends a message to the alarm devices to ring.
Certain alarm systems also have a set of flash lights or strobe lights that are set on by the control panel when they receive a signal from the initiating device. These lights are installed in addition to alarm so that people with hearing impairment can be alerted about the fire. The lights can also be noticed from a distance where sound of the alarm could not reach.
Manual alarm systems have manual levers that can be pulled to inform about the fire. These levers when pulled make a very loud noise to inform all occupants of a building. However, they need to be operated by an individual and thus, should be installed only in low risk places and where there are people working round the clock.
Hence, an automatic fire alarm system can safeguard your premises and your valuables even when no one is around.
