Fire Alarm System

The fire alarm system has designed to alert us to emergencies, so that we, staff and the general public can take action to protect them.

Fire alarms can find in offices, factories and public buildings, which are part of our daily routine but are ignored until they can save our lives in an emergency.

Regardless of the method of detection, loudspeakers also activate to warn and eliminate the possibility of a fire if the alarm has triggered.

The fire alarm system may also include a remote signal system that alerts firefighters through a central train station.

Different types of fire alarm systems

Fire alarm systems are divided into four main types;

–           Traditional

–           Can be addressed

–           Intelligent

–           Wireless

We take some time to consider each one.

1. Conventional fire alarm systems

In a traditional fire alarm system, physical cables use to connect several call points and detectors, and the resulting signal is sent to the master control unit.

Call locations and detectors are set up in “zones” to simplify finding the cause of the alarm, which is important for firefighters and general building management.

Each zone indicates by an indicator lamp, a text display, or in some cases both on the fire alarm control panel.

It makes sense to find the warning trigger more accurately so that we can divide a building into zones.

The control panel is wired to at least two sound circuits and may contain bells, electronic sounders or other audible fire alarm devices.

2. Addressable fire alarm systems

The detection principle of an addressable system is similar to that of a conventional system. Each detector is given a set address (usually by a dip-switch) and the control panel is able to determine exactly which detector or call the location the alarm was started on. .

3. Intelligent Fire Alarm Systems

However, in our next type of intelligent fire alarm system, each detector effectively integrates its own computer that effectively assesses the surroundings. And communicates to the control panel whether a fire, error or detector head needs cleaning.

Essentially intelligent systems have many more features than traditional or addressable systems. Their primary purpose is to prevent the occurrence of false alarms.

4. Wireless fire alarm systems

The last method we will consider is the wireless fire alarm system.

These methods are an effective alternative to traditional wired fire alarm systems for all applications. They use secure, unlicensed radio communications to intercept sensors and devices with controllers. It is a simple concept that offers a number of unique benefits. And it is a fully intelligent fire detection system without the need for cables
