Description

Wireless type fire detecting apparatus

The present invention relates to a wireless fire detection device.

More particularly, the present invention relates to a wireless fire detection apparatus in which a fire detector transmits a fire detection signal and an address signal in a wireless manner when a fire occurs, and the repeater receives the signal and retransmits it to the central controller.

In general, a sensor for detecting a fire includes a heat sensor for detecting heat generated by a fire, a smoke sensor for detecting smoke, and a steam sensor for detecting water vapor.

There are two types of thermal sensors: a constant temperature that sounds an alarm when a certain temperature is reached, and a differential that sounds an alarm depending on the rate of rise of the temperature.

In addition, the smoke sensor or the water vapor sensor includes an optoelectronic type that detects reflectance by projecting infrared rays onto smoke or water vapor, an ionization type that detects ionization by projecting α rays on smoke or water vapor, a resistance bridge type that detects resistivity, and a blocking rate of light. There is fog detection to detect.

In addition, since the fire detection device is constructed together with the electrical wiring when the building is newly constructed, there is a problem that it is difficult to change the existing building as well as the air.

Accordingly, the present invention has been made to solve the above problems, by installing at least one fire detector and one repeater in each section, when the fire occurs when the fire detector transmits the fire detection signal and the address signal in a wireless manner repeater It is an object of the present invention to provide a wireless fire detection device that receives this and retransmits it to the central controller and accordingly causes the central controller to display the situation.

A plurality of repeaters to be displayed; It is characterized by consisting of a central controller for displaying the fire occurrence state and the fire generating space by the wire detection type fire detection signal and the address signal received from the repeater.
