Frequently Asked Questions About Fire Alarm Systems.
In this article, we will try to answer frequently asked questions about fire alarm systems. We hope you will enjoy reading our article and find it informative.
What is a fire alarm system?
It is a security system that protects our buildings, facilities, and other areas from the material and spiritual damages that fire can cause. The fire alarm system is a comprehensive system consisting of a fire panel and various detectors that detect fire. Fire alarm systems detect fires and subsequently create an alarm to warn occupants.
How many types of fire detectors are there?
Fire alarm system detectors have different structures depending on the type of detection. Detectors that detect temperature are called temperature detectors. Detectors that detect smoke in case of fire are called smoke detectors. Detectors that detect flames during a fire are called flame detectors. There are also various gas detectors that detect explosive gases during a fire.
How does a fire alarm system work?
A fire alarm system constantly monitors signals from fire detection sensors. It compares the received data to determine if a fire has occurred. When a fire signal is detected by the detector, the fire panel creates a fire alarm according to the programmed technical details. It activates sirens and flashers and checks the control of the fire modules based on the fire scenario. In addition, the panel can generate a fire alarm based on the fire information received from fire buttons.
What kind of cable is used in a fire alarm system?
The cable used in fire alarm systems is a special communication cable. The fire alarm cable is known in the market as a 1x2x1.5+0.8 JH(st)H FE180 cable. Of course, the cable cross-section may vary depending on the distance of the loop lines and the fullness of the loop lines. The most important feature here is that the fire alarm system cable must be a fire-resistant cable. The FE180 feature means that it is resistant to fire for 180 minutes.
How and where is the fire alarm system used?
Fire alarm systems are used in almost every place today, ranging from our homes to our workplaces, factories, warehouses, apartments, and shops. By using a fire alarm system, we are able to protect ourselves against high fire risks at a low cost.
Does a fire detector detect cigarette smoke?
Smoke detectors used as fire detectors detect cigarette smoke as well as any other type of smoke. You should not smoke in areas where there are fire smoke detectors. Smoking can trigger the fire detector and activate the alarm.
Addressable Fire Alarm Systems.
A fire combination detector:
Combination detectors used in fire alarm systems are two-feature detectors that detect both smoke and temperature of the fire. In other words, a single detector is equipped with both smoke and temperature sensors. They are typically used in electrical rooms or areas related to electricity.
Does fire detectors require maintenance?
It is important to note that fire detectors used in fire alarm systems, whether they are temperature or smoke detectors, require regular maintenance. Detectors should be cleaned twice a year on average. After cleaning, the detectors should be tested, and their pollution levels should be checked and monitored through fire monitoring software. Smoke detector tests must be performed using smoke detector test sprays.
Where are flame detectors used?
Flame detectors used in fire alarm systems are specifically designed for use in certain areas. Flame detectors are mostly used in industrial facilities. If a fire has a fast-burning characteristic, meaning it rapidly rises with flames without producing smoke, then a flame detector should be used. For example, a flame detector would be the best option for detecting fires in oil and gas industries.
