Fire Detection Systems
Fire detection systems are systems that automatically detect potential fire hazards in your facilities and are intended to reduce potential damages and losses. These systems are permanently installed. With the aid of detectors that catch the fire early and send warning signals about it, they are turned on manually or automatically.
These detectors are activated by heat, visible and invisible smoke, or flames. Only detectors close to the fire activate and send a signal to the fire detection control panel. From here, the fire is put out by sending the necessary information to the automatic fire extinguishing system and/or the fire safety unit. After the fire has been extinguished, the system can be quickly and easily reactivated.
CONVENTIONAL FIRE ALARM SYSTEMS
Conventional fire alarm systems have been in use for a long time and have changed little over the years. They are hugely common in small spaces or where there are financial constraints. In a typical conventional fire alarm system, a push button or a conventional detector activates the fire alarm control panel, causing alarm sirens to sound to alert people about the fire. The panel is wired with conventional detectors using "zone" logic. They are coded in two states: "Normal" and "Alarm." When any detector detects, a signal with the "zone" code is sent to the panel. The detection systems of gas extinguishing systems are generally designed as conventional.
ADDRESSABLE FIRE ALARM SYSTEMS
Addressable fire alarm panels, which provide point detection, are far more advanced than their conventional counterparts. Each detection element in these systems has an address, and thanks to microprocessor technology, there is constant communication between the alarm panel and the elements, and the status of each element is continuously reported to the panel. Intelligent fire alarm systems can be programmed specifically for the area to be used. Additionally, they can be used to receive data from other systems and manage different pieces of equipment within the systems via monitoring and control modules.
AIR SAMPLING FIRE DETECTION SYSTEMS
The air sampling smoke detector is a method used to detect the smoke generated in the event of a fire. The detector, the air sampler tube, and the air sampling holes are the three main components of these detectors. The fan inside the detector draws air from the protected area into the detector through the air sampling holes. The presence and amount of smoke in the chamber inside are detected. Meanwhile, air-sampling smoke detectors first send preliminary information to the control panel and then the fire alarm signal to the fire alarm panel. As a result, different amounts of smoke are detected and reported. Air sampling systems are particularly useful in high-ceilinged telecommunications centers, cold rooms, and other locations where other detectors cannot be installed due to ceiling height.
GAS DETECTORS
Gas detectors are used to prevent fires and/or explosions in environments where flammable and explosive gas leaks are possible. Every gas type has a specific type of gas detector produced for it. Thanks to the pellistors inside, they detect gas leakage and send a signal to the relevant electronic control panel. Depending on the system's features, this control panel can also send a command to close the gas shut-off valve.
FLAME DETECTORS
Flame detectors are preferred in locations where there is a high risk of loss of life and property, such as oil and gas pipelines, turbines, oil platforms, automotive factories, nuclear facilities, and hydrogen filling stations. They perform according to the optical principle. Each combustible has a unique flame characteristic, and each flame color has a different range of wavelengths. Due to the optical cells that detect the flame, they can be activated very quickly in places where there is a risk of burning flammable materials. UV/IR flame detectors with IR, UR, or both are available.
CABLE-TYPE HEAT DETECTORS
Cable-type heat detectors (LHD) can be described as point heat detectors that are continuously arrayed in a safety cable. They are particularly used in interior or exterior areas that are difficult to maintain and contain a high level of danger. It is suitable for facilities with dirt, dust, corrosion, high humidity, extreme temperature changes, solvent vapor, radioactivity, and ATEX class. There are two different types, Analogue and Digital. Analog cable-type heat detectors work by collecting data along the cable. Temperature control is possible at any point along the cable by using digital cable heat detectors.
