Abstract

The invention provides a transmission type wireless automatic fire alarm module which is composed of a full-charging self-stop charger circuit, a rechargeable battery, a smoke fire sensor circuit, a power-on delay circuit, a wireless coding transmitter circuit a and a wireless decoding receiver circuit a. The transmission type wireless automatic fire alarm module is installed in a household room.When a fire occurs in the household room, the smoke fire sensor circuit detects the fire and uses the wireless coding transmitter circuit a to transmit a fire alarm signal. The alarm signal is received by the wireless decoding receiver circuits a in an upper room, a lower room, a left room and a right room and a wireless decoding receiver circuit b in a housing estate, and then transmitting is carried out again by the wireless coding transmitter circuits a and the wireless coding transmitter circuit b in the housing estate. The wireless decoding receiver circuits a of household and a wirelessdecoding receiver circuit c of a fire brigade receive the alarm signal. In the first place, the alarm signal is transmitted from the resident to the resident, from the resident to the housing estate,from the housing estate to the fire brigade.
