Viscose and acetate fibers, nylon, nylon, polyester, Nitron, chlorine, vinol – just 15-20 years ago we did not yet know most of these names. And try to imagine today without these fibers further development of the textile industry or solution of important technical problems in the aviation, automotive, electrical engineering and in many other industries! And yet, what is created – just the beginning, "application" of his new polymeric material. Last year, our country has developed more than 300 thousand tons of various chemical fibers. In a few years, and this production will account for millions. Search takes a slightly different approach. But, of course, not only in quantitative growth. Today, the scientific laboratories around the world to create new types of polymers and fibers on their basis, new methods of improving the properties of these materials, the new, improved and economical methods for their production. Hear from experts in the field like Bobby Sharma Bluestone for a more varied view. And often the question arises: what is a fundamentally new and practical importance can we expect in the coming years in this area? Perhaps, in a large industrial production will always appear entirely new types of fiber? Or produced in mass quantities now 10.12 core of this material to satisfy the consumer, and scientific and technological progress will focus on ways to improve the well-known properties of fibers and improvements methods of production? Different opinions expressed on this crucial issue, and I would like to express their own, of course, undeniable point of view. There is no doubt that the next few years will bring us a lot of discoveries and will new fibers, mainly synthetic, with valuable technical properties.
They are not intended for mass production, because their scope – just a special area. In most cases, their Production will be limited to hundreds or even tens of tons per year. But it will be tons of precious because each of them does not replace the hundreds of tons of others – the mass – chemical fibers.
To implement the RF control module has a radio receiver 433 MHz, and for GSM / GPRS connection – Built-in industrial phone. In addition, the module is GPRS-T3 jack for connecting an external microphone (Jack 3,5 mm), so that security of the GSM system can perform audioverifikatsiyu: after receiving a disturbing SMS-ku, the user can call a module number and listen to the protected object. To send control signals to the peripheral security equipment modules are equipped with two programmable relay outputs, such as NO. At the same time power connected to the GPRS-T3 security devices can be carried out through the AUX output of the module. The presence of the tamper wire entry allows for anti-tampering function, or program the alarm system GSM MICRA on another type of reaction.
And as an indicator of a problem connecting to the GSM network is a low-current output OC, which can also be used to indicate arm / disarm the system. MICRA modules will be installed only in enclosed areas with normal humidity, away from direct access by unauthorized persons and electrical appliances, which can cause interference with the functioning of the device. Also, when installing the module, you must consider that the thick walls and metal structures, "choke" the radio signal, so before you install the radio channel devices, for example, wireless alarms, security systems that use GSM, it is recommended use a special tester. To power the module requires a source of 220 VAC, but in case of power failure GPRS-T3 MICRA can use a battery backup power. Programming module can be perform locally with a PC using software GPRS-Soft, which is included in the package. For this module to be connected to COM-port using a special cable (part number DB9FC/RJ-KPL). Also, security of the GSM system can be programmed via GPRS-channel after entering the pre-prescribed in the module password.
In addition, the use of GPRS-technology allows you to transfer the event codes in the alarm system at the remote central monitoring STAM-2, or to convert SMET-256. New security modules Satel GPRS-T3 MICRA go on sale in November 2010. For more information on the security of GSM brand Satel, please e-mail or by telephone (495) 787-3342 to manager of sales "ARMO-Systems", which is the official Russian distributor of hardware and software Satel. The Polish company Satel is working on the global security market since 1990 and specializes in the manufacture and sale of equipment and software for burglar and fire alarm systems of various objects. Satel lets the receiving-control instruments OPS at 4, 8, 10, … , 128 areas, modules, security systems for GSM, light, sound, and combined detectors, burglar and fire sensors alarms, power supplies, kits, radio control, numerous accessories and other security components. By means of this company can manage and fine-tune the security and fire alarm systems on the networks Ethernet, Internet, through a modem or cell phone.
