Detector-launching devices «Pulsar 31».

The UDP «Pulsar 31» combines all the functions of a mini automatic fire extinguishing system. The UDP has a two-spectrum open flame detection sensor, a signal analysis and control circuit, a powerful cascade for issuing a starting current to start a standard powder, aerosol or gas fire extinguisher, as well as its own 12-month battery power source for autonomous uninterrupted operation of the device, its own short signal loop protected by a shielded cable from electromagnetic interference, and a strong steel bracket and housing that protects the device from mechanical damage. This means that all the functions of a complete fire extinguishing system of sensors, a control panel and a starting device, and fire extinguishers are in a single device. Therefore, the first advantage of the UDP «Pulsar 31» is that one single device, supplied already assembled, saves from the difficulties of assembling a system from separate devices from different manufacturers. UDP «Pulsar 31» from the PPP plant «KB Pribor» provides a single ready-made solution for effective home protection.

The advantage of reliability and efficiency of the UDP «Pulsar 31» is provided by special developments of the PPP «KB Pribor» plant in the field of fire detection sensors. In the process of developing the most modern and protected modification of the open flame detector «Pulsar 3-015», solutions were born for 100% protection of optical devices from sunlight, lightning flashes, and radiation from electric arc and electric gas welding. These solutions are now available in the UDP «Pulsar 31» device.

The main solution for protection against powerful optical interference is the use of two optical channels with sensitive sensors for different spectral ranges and analysis of the signal ratio between these channels. The UDP «Pulsar 31» uses a reliable photodiode from the Japanese company Hamamatsu, which has shown good practical results. Another important solution is a special optical mixer that distributes radiation from the controlled area evenly to two sensitive photodetectors. This solution of the optical system was carefully calculated by plant specialists, tested in laboratories and tested in practice.

Here it is interesting to shed light on a question that many people who are starting to work with open flame detectors for the first time ask for customers: “Will your detector be triggered by radiation from the body of domestic animals, their movement, warm air vibrations, radiation from heating batteries or a gas stove, as it happens with security sensors configured for the IR range?” This question has become the most pressing today in terms of the number of calls and written inquiries from customers to the KB Pribor PPP plant. The answer is simple: “Pulsar detectors detect radiation in the near infrared range, starting from a heated body temperature of 800 degrees, and it is clear that neither domestic animals, nor heating batteries, nor even stoves produce such a high temperature. Therefore, Pulsar detectors of all modifications are completely indifferent to thermal radiation. The result is 100% protection from optical and thermal interference, that is, the device is guaranteed to be triggered only by fire.

The ease of use and simplicity of operation of all modifications of the Pulsar detectors has become a valuable advantage for customers, and this advantage fully applies to the UDP Pulsar 31. As before, the flame sensor requires virtually no maintenance, is indifferent to dust and soot, and even to the film of oil and fat on the remote element, it is enough to wipe it with a cloth once a year. For convenience, on the side surface of the UDP there are buttons «Battery control» and «Start circuit control». With these buttons, you can always check the operability of the device.

And four large high-brightness LED indicators provide good visual control of the device's operation. These indicators: «Attention», «Start», «Battery control», «Start circuit control».

The red «Attention» indicator lights up when there are at least some optical signals in the monitored area. The red «Start» indicator lights up when the device has decided on a fire and provides a 30-second delay for evacuation of people before releasing the extinguishing powder. The device can be switched off using a toggle switch hidden in the terminal box.

The UDP «Pulsar 31» is an autonomous device powered by lithium batteries. It does not require external power supply, and the service life from one set of batteries is calculated from 1 year to 3 years or even more, depending on the intensity of the device. The fact is that open flame detectors usually consume relatively much energy to analyze signals, compared to simple heat and smoke detectors, and until now there has been no solution for an autonomous flame detector on the market. Now there is such a solution. The UDP «Pulsar 31» has a special independent micro-consuming channel on modern field-effect transistors, which is constantly on, analyzes the situation in the room, and if there are at least some optical signals, it turns on, «wakes up» the main and compensation channels for flame detection with an amplification path on the latest integrated microcircuits of ultra-low consumption from Phillips and National Semiconductor. Such microcircuits for battery power supply have only recently appeared on the market, and only now has such a modern development of a micro-consuming device, equipped with a processor signal processing and a good proven amplification path, become possible.

Now, if the device is in the garage, protecting the car, then optical signals will appear there very rarely, and the «alarm clock» path will only occasionally connect powerful signal analysis tools to work, accordingly, the energy consumption will be insignificant, and the batteries will last 3 years or even more.

If the device is located in the kitchen, near the window, where there is high illumination, where the sensitive element is exposed to glare from the sun, then the device will necessarily turn on the main and compensation channels, and the consumption will increase significantly, but even with such intensive work, 12 months of work with one set of batteries are fully guaranteed!

According to today's price list of «PPP — KB Pribor», the cost of the UDP «Pulsar 31-2» already assembled with the MPP-6 «Tungus» with a volume of 6 liters is 7493.0 rubles, including VAT 18%.
