A home alarm system is designed to optimize the protection of occupants and their belongings. With tools such as the remote control or alarm keypad, managing this system becomes simpler and more convenient.

The keyboard: the indispensable tool

Very practical, the alarm keypad is the component of the alarm system that allows to manage the globality of the device settings. When it is not built into the alarm unit, it must be installed nearby, since it is the main interface of the unit. Its primary function is to enable or disable the home alarm, although it also allows several other operations. For exa

The super-regenerative radio remote control circuit consists of a radio transmitter and an ultra-regenerative detector receiver. Radio transmitters: It is composed of a high-frequency carrier-frequency oscillator (usually 30~450MHz) that can produce equal-amplitude oscillation and a low-frequency oscillator that generates a low-frequency modulation signal. The circuits used to produce the carrier-frequency oscillator and the oscillating oscillator is generally: multiple oscillators, complementary oscillators, and quartz crystal oscillators. Low frequency modulated wave generated by the low frequency oscillator is generally a square wave with a certain width. If multi-path
