UV-IR optical detectors are a type of sensor used in fire detection systems. These detectors are designed to detect both ultraviolet (UV) and infrared (IR) rays to detect fire hazards at an early stage.
Fire detection systems are used to detect fires that can occur in enclosed spaces such as buildings or other structures and to take appropriate emergency measures. UV-IR optical detectors are one of the most important components of these systems because they can quickly detect small flames that usually occur at the initial stages of a fire.
These detectors are widely used, especially in industrial operations and high-risk areas. UV-IR optical detectors play a vital role in ensuring fire safety and are important in protecting people and property.
Detectors have been specially designed as IP67 and can stay under 1 meters of water for half an hour. The detectors also having protection for false alarms, do not react against false alarms such as sunlight, vehicle headlights, welding beam, infrared heater, cigarette ash. Along with these systems protecting the engine and the crew on military armoured vehicles, electric vehicles, buses, planes, jet planes and ships; total 40 thousand detector accomplish their duty in the field.
UV-IR optical detectors are used in military vehicles’ fire safety systems to detect fire hazards at an early stage and help ensure the safety of crew and personnel onboard. These detectors are commonly used in armored vehicles and other military vehicles in critical areas like the engine compartment and fuel tanks.
UV-IR optical detectors are also used in naval vessels. These detectors help detect fires early on inside a ship and ensure the safety of crews and other personnel onboard.
UV-IR optical detectors play a crucial role in fire safety in military vehicles and other sectors.
UV-IR optical detectors are used in fire detection systems and are widely used in industrial operations and high-risk areas. These detectors are also used in logistics centers, commercial buildings, airports, hospitals, hotels, shopping malls, and other large structures’ fire safety systems.
UV-IR optical detectors are also used in the marine and shipping industries. These detectors help ensure the safety of crew and passengers by detecting fires early on inside a ship.
UV-IR optical detectors come in different types for fire safety. Some of these include:
Conventional UV-IR detectors: These detectors detect both ultraviolet (UV) and infrared (IR) rays to detect fire hazards at an early stage. They are typically used in industrial operations and high-risk areas.
Tunable diode laser detectors: These detectors are designed to specifically detect gas fires. They can be connected directly to fire suppression systems and allow for early intervention in the event of a fire.
Linear detectors: These detectors consist of many small photoelectric cells that are interconnected. This allows for a wider detection area and greater sensitivity. Additionally, linear detectors can be used as a sensor that can locate the position of a fire.
Inductive optoelectronic detectors: These detectors consist of an electromagnetic coil that absorbs light and a photoelectric cell or photodiode. They are designed for use in industrial environments and can typically operate in dusty or smoky conditions.
The different types of UV-IR optical detectors can be selected and installed based on the needs of fire safety systems.
UV-IR optical detectors come with many features for fire safety. Some of these features include:
Dual wavelength detection: UV-IR detectors detect both ultraviolet (UV) and infrared (IR) rays to detect fire hazards at an early stage.
Fast response time: UV-IR detectors can quickly detect small flames and help take emergency measures.
High sensitivity: UV-IR detectors can detect even small flames and smoke at the initial stages of a fire.
Long lifespan: UV-IR detectors are designed to have a long lifespan and require minimal maintenance.
Durability: UV-IR detectors are produced to withstand harsh environmental conditions and resist impacts.
Self-testing capability: UV-IR detectors can self-test regularly and notify when there is a malfunction.
Easy installation: UV-IR detectors are designed to be easily mounted and installed.
The different features of UV-IR optical detectors can be selected and installed based on the needs of fire safety systems.
The Optical UV/IR Detector high speed response is being installed in military tactical and combat vehicles.
The detector is micro controller based enabling adjustment of sensitivity and other features to a specific application.
A serial communication port provides outputs for maintenance and diagnostics.
Only simultaneous detection of radiation in the UV and IR ranges of the electromagnetic spectrum (which are characteristic of fire) and above preset threshold will result in a detector output signal.
All other types of radiation sources, not identified as fires, will not be detected.
There are specific standards for testing UV-IR optical detectors. These standards are used to evaluate the performance of detectors and determine their suitability for safety purposes. Some common UV-IR optical detector test standards include:
EN 54-10: A standard for fire detection systems in the European Union.
UL268: A standard for fire detection systems in the United States.
FM 3230: A standard for factory insurance and widely used in the United States.
ISO 7240-28: A fire safety standard that is accepted worldwide.
These standards provide test procedures to determine the sensitivity, false alarm rate, environmental durability, and other performance characteristics of UV-IR optical detectors. Testing UV-IR optical detectors according to standards ensures that fire safety systems operate correctly.
UV-IR optical detectors are used for fire safety. These detectors detect both ultraviolet (UV) and infrared (IR) rays to detect fire hazards at an early stage. The tasks of UV-IR optical detectors include:
Identifying fire risks: UV-IR optical detectors continuously monitor the surrounding environment to identify potential fire risks.
Early warning: UV-IR optical detectors quickly detect small flames and provide early warnings to assist in intervention.
Ensuring safety: UV-IR optical detectors detect fires at an early stage to ensure the safety of crew and other individuals.
UV-IR optical detectors are used in industrial operations, high-risk areas, commercial buildings, airports, hospitals, hotels, ships, and other large structures’ fire safety systems. UV-IR optical detectors play a vital role in fire safety and are essential in many sectors.
