1. The signal transmission of the home alarm system is much more reliable than that of the building intercom, the home alarm signal is not allowed to be lost, and the response speed is fast;
2. Security-type building intercom is communicated through intercom line. If it is a single-channel system, the system may be busy (busy).
Select security building intercom key
1. Building Talkback System Design: When choosing a security building intercom system, you must ensure the buildability of the networked system! Design must be stable and reasonable! Isolation protection and fault information forwarding must be precise and fast! It must be required that the building intercom system has a multi-channel (or independent) alarm information channel! To ensure that the alarm information can be notified to the user or the security personnel of the management center at the fastest time! Secondly, the building intercom system must take automatic circuit inspections to detect the status of the equipment and wires in the network at any time! Prevent problems such as alarm messages that cannot be transmitted due to natural and human-induced faults!
2. The management center machine and the user indoor unit are the key: The management center machine must have the principle of multi-channel working at the same time. The alarm information at any time must be given priority by voice plus character! The voice prompts can alert the security personnel present at the scene; they serve the function of warning and reminding; the characters accurately display the alarm types and addresses and types, and the security personnel make correct decisions based on the alarm address and type of the police displayed by the management center. The processing method to avoid the loss of property; followed by the front-end equipment, indoor machine user machine can be made of performance! Indoor extension must have super stability! Stable operation at any time! Precisely distinguishes the working status of each police type! The indoor user's machine is easy to operate and can be withdrawn and armed at any time for each type of police.
3, the function of the corresponding equipment must be complete: the user indoor unit, the unit door host, the management machine must have withdrawal, arming management! And can quickly and easily remove the defense; building intercom system related accessories, must have the level of intelligence, can forward all kinds of alarm, fault information function, with superior protection!
4, the corresponding alarm detector: the corresponding alarm detector must have linkage alarm function (more on-site alarm function is better); alarm detector must be stable and reliable; to reduce false positives!
5, power supply management: As the network system has automatic inspection line function; detectors may be deployed at any time, disarm, ready to work! The source of the system's capabilities - the power supply must be stable and reasonable, with a variety of fault protection features!
6, the installation of equipment: equipment involves two aspects: First, the use of wire must meet the system design requirements! The second is that the installation of equipment must be strictly implemented according to technical requirements! Ensure that the installation of each alarm detector is reasonable; ensure that all wiring ports are firm; ensure that the corresponding building intercom equipment is installed stably and reasonably.
7, as long as the above problems are handled well! The realization of security-type building intercom is very promising!
From the project cost point of view: building intercom + home alarm = security intercom, choose security building intercom system is relatively cost-effective. This is also the reason why the building intercom system of the four defense areas or more defense areas is under the influence of greenery! As a building intercom industry insider, the security defense building now has a relatively strong security requirements. We don't want to have many functions. There are many alarm detectors and many are not necessarily practical. We must be reasonable!
High Temperature Alloy is divided into three kinds of material: 760 ℃ high-temperature material, 1200℃ high temperature and 1500 ℃ high temperature materials, the tensile strength is 800 mpa. On other words,it refers to the metal material worked well in the condition of 760-1500 ℃ or above. It owns excellent high temperature strength, good resistance to oxidation and thermal corrosion resistance, good fatigue properties, fracture toughness and other comprehensive performance, this kind of material has became an irreplaceable key material in military and civilian gas turbine engine hot end components . According to the relevant theory, 760 ℃ high-temperature materials, according to the matrix elements,can be mainly divided into high temperature iron base alloy, nickel base superalloy and cobalt-based super alloy. According to the preparation process,it can be divided into deformation and high temperature alloy, casting high temperature alloy and powder metallurgy super alloy. According to the solid methods,it can be divided into solid solution strengthening, precipitation strengthening and oxide dispersion strengthened with fiber reinforced type, etc.
