Fire detection and alarm systems are vital systems that are officially included in the regulations. In places where there are a lot of people such as shopping malls or hotels, a business license cannot be obtained without fire and alarm systems. These systems have fire detection and alarm systems, different scenarios and installations according to the structures, by preventing the loss of life and property to a large extent, by enabling the fire to be intervened quickly at the smoke stage.
The purpose of all fire detection and alarm systems is the same, but there are different systems according to the needs. These systems definitely require expert support. In addition, these systems should be legally maintained and checked.
By anticipating the danger, it has a significant effect on preventing the loss of life and property at the scene. If you wish, let’s open these systems a little more technically.
- Analog Addressable Fire Alarm Systems,
- It is listed in two different ways, Conventional and Analog Addressable.
1. Analog Addressable Fire Alarm Systems
In these systems preferred by large buildings, the device addresses of the elements that make up the fire system (smoke and heat detectors, multi-sensors, beam detectors, fire buttons and sirens, fire flashers) and the physical place where they are installed matches exactly on the flat or floor plan. In other words, it’s like we got a fire warning in the kitchen of the 4th flat of the 13th floor of the A block.
All elements such as smoke detection or devices that control the temperature rise are connected with a loop line or a ring logic on a line and send information to their own fire units. In case of any warning, the system works and gives an audible warning. The fire element, that is, the location of the installed devices and the exact naming, will be seen with that name on the fire control panel in any case. Being punctual reduces the safety of property and life to a minimum.
Fire control panels give warnings in sync with each other, by checking each other’s inoperability. At the same time, with the fire software installed on a computer, it is seen where the fire warning comes from on the screen.
These systems also warn people by making emergency announcements with voice warning systems and, integrated with Card Pass (Turnstiles) systems, enable people to evacuate easily in case of panic by automatically opening locked doors and turnstiles.
2. Conventional Fire Alarm Systems
Conventional fire alarm systems are simpler and cheaper than analog addressable systems. Conventional systems, which can only detect fires in the area where the system is installed, detect the fire through the signals of the detectors and give a warning only to that area. Conventional fire alarm systems are preferred in small buildings with low probability of fire.
Fire elements, smoke and heat detectors, fire buttons and sirens, beam detectors, fire flashers are also used in this system. The shortcoming of conventional fire alarm systems is that they react quickly to temperature rise and sometimes give false alarms.
How do fire alarm systems work?
Fire alarm systems, as we have explained before, operate with the logic of audible and light warnings by activating the warning mechanisms in case of any change in the area where the heat and smoke detectors are located.
While designing all fire systems, the competence of the job and the reference companies that the company has installed before should be checked. It is known that many of their customers are having problems in many seemingly large companies in the market right now. For this reason, a business contract should be made after the research and information is obtained by talking with the technical affairs departments of the company that makes fire systems, the workplaces they support and their previous customers.
How to Install Fire Detection and Alarm System?
The installation of fire detection systems is clearly stated in the Regulations on the Protection of Buildings from Fire as required by law. Discoveries should be taken from more than one experienced company and compared. The compliance of these systems with the regulation and the compliance of the fire elements to be used with the Pak Standards are important. Since fire projects are one of the most critical jobs, post-installation tests should be done one-on-one.
