For challenging projects with applications that are at the forefront in many fields, AP Sensing products have become an indispensable solution, with their ability to perform precise measurements over long distances without any problems and using only passive materials in the field.

AP Sensing, which has 20 years of experience in the field of OTDR measurement technique (optical time domain reflectometry), has entered the field of fire alarm systems with DTS (Distributed Temprature System). AP Sensing is Agilent Technologies' marketing and distribution business for DTS systems, which is the world leader in optical measurement and provides the latest opto-electronic component processing technologies.

Since its foundation, the company, which was established up to produce innovative and reliable solutions in the field of fire detection systems, has been involved in many large and prestigious projects. . AP Sensing carries out all its production and R&D activities in Germany.

AP Sensing - Fiber Optic Fire Detection Systems are designed to reduce the cost of service and maintenance and to ensure optimum reliability, even under the following adverse conditions:

• Dirt, dust and corrosive atmosphere
• High humidity and extreme temperature changes
• Solution vapor and radioactive waves
• ATEX class explosive dust and gas hazard areas

AP SENSING FIBEROPTIC TEMPERATURE SENSING SYSTEMS

These systems are especially used in difficult conditions such as highway tunnels, rail system metro lines, industrial facilities where dust, dirt and humidity are high.

The system not only detects various forms of fires quickly and reliably, but can also locate the fire with an accuracy of a few meters. Without being affected by the storm, the system can identify not only convection heat waves, but also thermal heat waves.

In addition to all these features, thanks to the capability of the sensor cable to withstand temperatures up to 1000 ° C without losing its tracking capability, the system has the ability to follow the magnitude and expansion direction of the fire for a long time.
Thanks to these features, countermeasures can be managed effectively and essential details can be given to those responsible for the incident, such as fire location, volume, heat evacuation. (This information was obtained in 1: 1 fire tests conducted by the Swedish SP Technical Research Institute.) 

AP Sensing “Linear Heat Series” - the best option for these applications.

Environmental conditions such as dirt, dust, and moisture in the environment prevent detection using traditional fire detection systems in projects such as industrial facilities, highways and subway tunnels. Traditional fire alarm techniques tend to give false alarms and cause significantly expensive maintenance costs, which are heavily affected by bad environmental conditions.

In terms of performance and technology, a fire system used in industrial facility projects where high security is needed is required to provide the following requirements:

• Low maintenance costs and security against false alarms during normal operation.
• Resistance to dirt and corrosive gases. (environmental factors such as exhaust gases, humidity, dust, dirt)
• It is not affected by high air currents and environmental factors.
• Immunity to parasite fields. (such as tunnel radio, mobile radio, fan vibration, EMC.)
• No change in sensitivity due to temperature fluctuations. (traffic accumulation, air change etc.)
• Stable system structure.
• Providing reliable alarm triggering in dangerous situations. Successfully implementing the necessary precautions in accordance with the fire fighting strategy. (Activation of audible and visual warning, taking protective
• measures such as smoke evacuation and extinguishing, etc.)
• Detection of radiant and convection heat.
• Fast and reliable alarm detection before a complete fire breaks out.
• Ability to accurately transmit specific data such as fire progress direction, alarm zone (stopped, moving in the direction of the device, away from the device) to the fighters..

As a major moment that takes fire protection to a new level in projects such as industrial facilities, highways and subway tunnels, AP Sensing - Fiberoptic Fire Detection Systems provides us with creative solutions.

Using only one fiber optic cable for thousands of points of detection is appropriate.

No region is left out of sight by AP Sensing-Fiberoptic Fire Detection Systems. The device enables continuous monitoring of the development and propagation of heats within the entire protected area in real time. By reading thousands of heat values every 10 seconds along thousands of meters of fiber optic cables, the AP Sensing 'Linear Heat Series' based on the quantum mechanical RAMAN effect and patented measurement system (Code Correlation - OTDR) generates a perfect heat profile.

We are provided with comprehensive security by AP Sensing, which uses the highest degree of system compatibility and its unique method of producing optical elements. Fault-free, continuous operation and quick assembly are completed with this system solution. Many components of the system are carefully selected, developed to provide the highest quality and the lowest failure rate

- Defining different targeted alarm criteria and sensitivities on the same sensor cable

The system allows us to define 5-parameter alarm criteria;

• Static high value
• Adaptive peak value (takes into account the temperature value of the environment, positive delta to the zone average in ° C)
• 3-stage heat curve for different temperature rise characteristics (Temperature rise rate and constant value exceeding)

Tunnel entry and exit points are more affected than the inner sections of the tunnel by temperature changes. Because of wind and air movements caused by mechanical fans, sections with constant high and low temperatures can be generated in the tunnel.
The AP Sensing 'Linear Heat Series' will identify various alarm sensitivities for different areas of the cable in order to cope with these variable temperature conditions. The system also allows the "negative" alarms used in the icing alert to be configured.

-Having a large variety of solutions for products.

The capacity of the central unit includes 1,2,4 channel options. Solutions can be provided for a wide range of products, from 1 km to 40 km in unit capacity. For projects of several variable quantities, this helps us to step forward with the most optimal solutions.

With fiber optic line control and Class-A connection, even when the fiber optic line is broken, the device will run continuously with a 100 percent redundant connection

- Even in areas with an explosive atmosphere, the sensor cable can be used without taking additional safety precautions. It has an ATEX certificate because of this functionality

The laser source (laser diode) of the unit is in 1M or 1 class according to IEC 60825-1: 2001. The laser source also conforms to FDA 21 CFR 1040.10, with the exception of Article 50 issued on July 26, 2001, prepared for laser aberrations. Reliability of the product according to IEC 60825-1: 2001, deviations according to CAN / CSA-C22.2 No.61010-04; Tested and approved according to UL 61010-1: 2004
