Most Intelligent Fire Detection and Alarm Systems Out There

Most Intelligent Fire Detection and Alarm Systems Out There

Did you know that most of all the fires in Ireland (about 92 %) happen in a private dwelling? That is because business owners have become much more aware of modern fire alarm systems, fire detection solutions and fire alarm regulations. Fire alarms can save lives and guarantee the safety of your customers and employees.

How does the fire alarm system work?

Such a system includes several devices built to warn your employees and customers via audio and visual appliances every time fire, smoke, carbon monoxide are detected. A basic fire alarm system can also activate safety control functions and alert the local fire department. The alarms can be initiated manually (manual call points, pull stations) or automatically (smoke or heat detectors).

Types of fire alarm systems

They usually distinguish conventional and addressable systems.

The conventional system makes use of a physical cable to connect detectors and call points. Their signals are transmitted to the control unit.

Each detector in the addressable system is given a set address so that the control panel can determine the exact place of fire.

There are two more advanced types: intelligent and wireless systems. The main purpose of the intelligent system is to prevent false alarms. Such systems are far more complex, and the detectors evaluate the environment and come up with decisions. Wireless alarm systems use free radio communications to transmit signals and connect devices and controllers. 

What kind of fire detection solutions are there?

Detection devices are the core of any fire alarm system. They vary from complex intelligent multi-sensor detectors to simple break glass units. Here are the most advanced options available in the Irish market nowadays:

Heat Detectors

The heat detector triggers an alarm if the temperature changes or exceeds a certain value. Heat alarm is preferred for areas with dust or smoke so that a standard smoke detector would not go off.

Smoke Detectors

It is recommended to have at least one smoke alarm on each storey. For commercial property, such as offices or hotels, a smoke detector in every room is the requirement. There are ionisation, light scattering, light obscuring smoke detectors. The main disadvantage is that they are a bit too sensitive and may cause false alarms.

Carbon Monoxide Detectors

CO fire detectors indicate fire by identifying the level of carbon monoxide in the air.

Optical Smoke Detector

In this case, detectors use the IR light scatter principle, its chamber is usually protected from insects, dust and other objects.

Multi-Sensor Detectors

These fire detection systems receive inputs from optical and heat sensors. They process these inputs using an algorithm built into the detector circuitry.

Such detectors are sensitive to different types of fires.

What industries implement intelligent fire alarm solutions?

Fire detection systems are installed in factories, offices, hotels, hospitals and other public buildings and manufacturing facilities. It is crucial to choose the right fire detection solution. For instance, ionisation, optical, and photo-thermal detectors may not be suitable for areas subject to steam, smoke, dirt or dust during normal use.

Moreover, when installing and choosing the proper place for such devices, it is necessary to consult national and local standards. Fire alarms are often overlooked as they are just a part of our everyday routine.  But in the case of emergency fire alarms are going to save our lives.
