Guangzhou Yi Li Fu Electronic Technology Co., a professional burglar alarm manufacturers, security recommended brand, mainly produces active infrared radiation (on December 1, 2013 launch of the fourth generation of large screen LED digital series of infrared radio), bus alarm host , electronic fence, WISEI defender series of sub-line anti-theft alarm, VOANDOS Vian Das series laser shooting, passive infrared detectors, smoke detectors, alarms and other accessories. When As people's living standards, modern design and home decoration, people's awareness of fire prevention awareness theft more often than, therefore, network security, anti-theft window installation and reinforcement work done is perfect, however, in the event of residence such as fire When such emergencies, such families could not escape in time to do the work, there is a big security risk, in this, our company made the following thought: When families home design, set aside one or two windows do not install anti-theft network; specifically design security alarm circuit, and implement effective installation. Has been designed based on well-alarm device, install it in the right place, in order to achieve accurate real-time alarm, I think the Secretary glass break alarm sensor is preferably mounted on the same side of the wall and the glass, because both easy to detect by the Building shock was delivered, but "listening" to the sound of glass breaking, then, the sound of glass breaking alarm sensors work most effectively, it can also be installed on the adjacent wall or ceiling. Upon examination, the device can only have 90 ° angle with the glass, so the glass break alarm sensor must not be installed on the wall opposite the glass. Acoustic glass break alarm sensor scope is very small, typically up to 6m, and it must be measured along the wall surface, if mounted adjacent the side of the wall, along the wall to be a corner, then along the wall to the installation measurements. This place within a 6m, straight-line distance from the window to the fact it is less than 6m, so, in many cases, in order to get the best coverage you need more sensors. These are the Guangzhou Electronic Technology Co. ALEPH design household glass break alarm installation method, Division I professional technical team, if other problems can enter our official website consulting.

Installation and use wireless door detector is usually installed above the inside of the door, it consists of two parts: the smaller part of the permanent magnet, the inside has a permanent magnet for generating a constant magnetic field, the larger is the wireless door body, it has an internal normally open type reed switch, when the permanent magnet and reed in close proximity (less than 1 cm), wireless door detector is waiting for the state, when the permanent magnet reed leave a certain distance high-frequency radio signals, wireless door detector immediately launch itself contains the address code and the identification code (that is, data code) of 315MHz, the host of the radio signal is through the identification address code to determine whether the alarm system is the same, then according to their own identification code (that is, data code), determine which wireless door alarm, therefore, a host can be equipped with a number of Menci detectors, as long as each door sensor detector address code with the host to address the same code.
