For a long time as a shut-off and control valves used valves and gate valves. Very often it was the valves and valves made of cast iron and very high quality. Many professionals who work in the field of installation and operation of various heating and water systems, are well acquainted with the problems encountered when used as a shut-off and control valves of traditional valves – the need for an annual audit for the packing seals and O-rings, cleaning disks from pollution, the complexity of the emergency line shutdown in emergency situations, lack of integrity, high percentage of failures due to a fall or accident cheeks bolts. Besides all this, the valve has large dimensions and relatively heavy weight. Today is a good alternative to conventional valves and valve – Ball cranes. Ball valves are made of nonferrous metals with thread to the pipeline are already widely used in plumbing, heating, gas, heat and power to individual nodes and industrial facilities. More information is housed here: Dell Computers. On objects of power (CHP, RTS, boilers, CHP, on the pipelines of heat networks), and numerous industrial applications where high demands for reliability, according to applicable regulatory requirements (SNP, etc.) use reinforcement from ferrous metals (including ball valves) with a socket connection to pipeline limited. Shut-off valves of non-ferrous metals do not recommended for use in pipelines with a diameter greater than 50 mm, operating at high temperatures and pressures, as the strength characteristics of the housing and the threaded connection is much lower than the reinforcement of steel and cast iron flange to the pipe and weld.
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.
