Description

Fire detector with condition indicator < RTI ID = 0.0 >

In general, buildings and apartments are equipped with fire prevention equipment and equipment to evolve in case of fire.

In order to mitigate the damage to the fire due to the increase in the human and material damage caused by the fire when the fire occurs due to the enlargement, And an automatic fire extinguishing system that automatically operates the fire extinguishing system when a fire is detected.

The automatic fire extinguishing system includes a sensing unit for sensing a fire, a receiver for sensing an operation of the sensing unit and generating an alarm, and an operation unit for automatically operating the fire extinguishing system in the event of a fire. The sensing unit senses heat or smoke When the fire signal is sent to the reception party, the reception party alerts the people in the building with an acoustic device such as a bell, siren, etc., and then fire extinguish material is sprayed to the fire place after the set time to evolve the fire.

A sensor unit including a body fixed to a ceiling surface and a cover including a sensing means for sensing heat or smoke while being fixed to the body and being capable of being engaged with or separated from the body; And display means for indicating that a fire has been detected through the sensor unit.

The fire detector may be a thermal sensor, a smoke sensor, or the like. Depending on the type of the sensor, a differential sensor, a temperature sensor, an ionization sensor, an ionization accumulation sensor, an AN smoke detector, Etc., and whether the normal operation of the plurality of detection sensors greatly affects the reliability of the fire sensing apparatus.

Therefore, in a conventional general automatic fire extinguishing facility, there are a plurality of fire detectors installed in every room of each floor in each place where a fire is predicted, for example, in a high-rise building, and a plurality of fire detectors installed in the fire detectors And a reception unit including a plurality of lamps and operation buttons that are turned on during the operation of the specific sensor.

When the fire detection apparatus is inspected, a plurality of inspection personnel are respectively located in the sensor of the fire detector, the reception unit, and the solenoid operation unit for operating the fire extinguishing system, and are communicated with each other using a communication device such as a walkie-talkie When a checkup person located on the detection sensor approaches a sensor near the sensor, the checker on the reception side checks whether the lamp 110 of the receiver 110 is turned on and other operations are performed, The checker of the solenoid checks whether or not the solenoid is triggered.

However, in order to check a fire detector installed at a height as high as, for example, 10 m or so, such as a parking lot, an indoor arena, or a factory facility, the fire detector with the detection sensor is equipped with a lifter Because it is necessary to use a special-purpose vehicle, the waste of resources for the operation is worsened.

At present, in Korea, it is stipulated as a law to check the fire detection device every six months in order to prevent complete fire prevention and minimize the damage in case of fire.

In the conventional inspection of the fire detection system, it is necessary to have a checker in each of the fire detector and the receiver, so that it takes a lot of time and time for the inspection and it is difficult to check the fire detector installed at a high place. Because it is close to the fire source, it is impossible to inspect the fire detector in the dangerous places such as the loss chamber or the gas chamber, and the fire detector is approaching the fire detector, so the set temperature at which the fire detector is operated can not be precisely adjusted.

As a result of the above-mentioned problems, the inspection is uncertain according to the legal inspection cycle, so that the reliability of the fire detection system is deteriorated and the fire accident can not be prevented thoroughly.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a fire detection system, which can improve the reliability of the fire detection system and thoroughly prevent a fire accident, And in particular, to provide a fire occurrence detecting means having an operation display function for displaying the operation state of the fire detector itself so that the fire detector installed at a considerable height can be easily operated without using special equipment.
