Wireless remote control 626 alarm

Abstract

The invention relates to a wireless remote control 626 alarm which can be matched with a wireless remote controller and a wireless detector for use by matching codes. A horn is used as an electroacoustic converting device, and wireless alarm host circuits composed of a power supply circuit, a wireless receiving decoding circuit, a single chip microcomputer control circuit and a horn driving circuit are all integrated into a hollow cavity in the horn. The wireless alarm host circuits are connected with an external direct-current power supply only through one power supply line. The wireless remote control 626 alarm is used through single chip microcomputer programming and is matched with the wireless remote controller and the wireless detector for use. The wireless remote control 626 alarm can have any one function or any two functions or all of three functions including a high-volume wireless doorbell function, a wireless remote-control alarm function and a wireless remote-control alarm function.

Description

technical field [0001] The invention relates to a wireless alarm, in particular to a wireless alarm which can be matched with a wireless remote controller and a wireless detector through code matching. Background technique [0002] The wireless doorbell is composed of a button on the wireless transmitter and a ringer on the wireless receiver. When the button on the transmitter is pressed, it will emit a wireless electromagnetic wave signal, which is received by the receiver, and the bell will emit a beautiful ringtone. Remind the owner in the room that there are guests coming from outside the door. The electromagnetic wave signal of the wireless doorbell has a long transmission distance, no wiring is required, and the installation is simple, so it is widely used in residential buildings, commercial offices and other places. However, the wireless doorbell in the prior art has a relatively small volume of ringtones, so it is only suitable for relatively quiet places. The rin...

Problems solved by technology

[0007] The 626 siren is generally used as an alarm. If you want to realize the function of the alarm, you need to connect the 626 siren with a special alarm host. Installation is more troublesome

However, it is impossible to use a certain chip to decode three different coded signals. For example, the chip PT2272 cannot decode the signal encoded by the learning code, and the chip NT2185 cannot decode the signal encoded by a million sets of learning code.
