Abstract

The invention relates to a public safety system, in particular to a fire alarm system. The fire alarm system comprises a sensor, a spray head, an alarm device and a master control module, wherein the sensor, the spray head, the alarm device and the master control module are arranged on various positions of a house. The fire alarm system is characterized in that the sensor is provided with a wireless transmitting module, the spray head and the alarm device are provided with wireless receiving modules, and the master control module is provided with a wireless transmitting module and a wireless receiving module at the same time; the sensor, the spray head, the alarm device and the master control module are connected in a wireless and point-to-point mode; each wireless transmitting module is composed of a transmitting module and a transmitting circuit in a breakover mode; and each transmitting circuit is composed of four ports from 10 to 13 in a breakover mode, wherein the ports are provided with switching values of diodes and pull-down resistors and PT2262 chips. The fire alarm system is mainly used for indoor extinguishment.

Description

technical field [0001] The invention relates to an announcement safety system, in particular to a fire alarm system. Background technique [0002] A fire alarm system for early warning and fire extinguishing functions is usually installed in a modern building for early warning and fire extinguishing. The existing fire alarm system is usually connected with cables in the fire-proof passage, and when a fire is sensed, it will send an electrical signal to notify the fire department, turn on the sprinkler to spray water, and sound the alarm. But in some cases because of the overlong use time of the fire escape in use or damage occurs, when a fire breaks out, the cable in the fire escape is damaged and the whole fire alarm system is paralyzed and cannot reach the desired effect. Contents of the invention [0003] The invention discloses a fire alarm system to solve the deficiencies of the prior art. [0004] In order to solve the above problems, the technical solution of ...
