Automatic Fire Alarm System is Developing Towards Intelligence

At present, the automatic fire alarm system is widely applied, in many places has become necessary equipment, and takes the role of safety guarder; but in actual application.

It also suffers from some problems in the market, such as bad product quality, single product function, product performance unstable, only detecting one kind of fire, and false fire alarm, this problem may cause large losses for people.

With the development of microprocessing technology, sensing technology, communication technology, control technology, and Artificial intelligence technology, now the automatic fire alarm system is developing towards intelligence and networking.

The main research direction is the intelligent (smart) style of auto fire alarm systems.

The main components of fire alarm systems include the fire detector, local fire alarm control panel, and central fire alarm control panel.

It also can work with kinds of fire equipment and communication equipment to form a central control system. automatic fire alarm, automatic fire suppression, fire evacuation, system display, and fire archive management to form a complete fire control system.

Trigger Element

in an auto fire alarm system, the element which is automatically or manually causes a fire alarm signal we call it “trigger element“, mainly includes a fire detector and manual call point, fire detector can get action fire parameters (like smoke, flame, heat, gas concentration).

It automatically gets a fire alarm signal.

Normally in the market, there are 5 styles of fire detectors, there are heat detectors (thermal detectors), smoke detectors, optical flame detectors, gas detectors, and combined fire detectors.

Different styles of fire detectors for different types of fire and different places.

A manual call point or manual start button is manually to get a fire alarm signal and start the automatic fire alarm system, it is a necessary component in fire alarm systems.

Fire Alarm Device

in an automatic fire alarm system, the fire alarm device is the one that can receive, display, and transfer the fire alarm signal.

And it also can send out a control signal and some other accessibility, we call it a ” fire alarm device”.

The fire control panel is one kind of fire alarm device, fire control panel has the following functions:

• offer heat detector with power supply.
• Monitor the work status of heat detectors.
• The fire detectors send out Receive, Transfer, and process fire alarm signals
• Indicate the fire alarm location and time.
• Main power and standby power automatic switching.
• Recharging of standby power.
• Failure monitoring functions of power supply.
• Fire alarm function and fire memory.
• Time function.

It is the heart of a fire alarm system.

In fire alarm devices, some other devices such as interrupters, zone indicators, and fire indicator panels, can be taken as ancillary equipment. They are applied in certain conditions, and just like a fire alarm control panel, they all belong to a fire alarm device.

Sounder&Strobe

In auto fire alarm systems, sounder&strobe is the device that makes out lights and voice, to warn people to take measurements of fire evacuation and fire rescue.

Fire Control Equipment

in automatic fire alarm systems, fire control equipment is the device that can automatically or manually activate relative fire fighting equipment and can display their working status, including the fire control panel, control equipment of automatic fire suppression system, the control panel of a fire hydrant, control equipment of exhaust and smoke control system and air-conditioning ventilation, control equipment of fire-proof door, the control panel of fire resisting shutter, control equipment of fire emergency lighting.

In addition, general fire control equipment and fire extinguishing equipment work together, and they achieve centralized and decentralized control by generating a common fire signal.

Power Supply

automatic fire alarm system belongs to fire equipment, its main power should adopt of fire power supply, standby power should adopt of battery.

The system power not only makes a power supply for the fire alarm control panel but also for some other relative fire control equipment.

Perhaps 10 years or 20 years later, the automatic fire alarm system with fire suppression system will get more and more intelligent.
