Description

An alarm of fire transmitter and receiver with return function

The present invention relates to a fire alarm, and more particularly, to a fire alarm transmitter and a fire alarm receiver with a return function that can easily release the operation of the fire alarm device by the user's malfunction.

In general, large buildings are equipped with automatic fire detectors to reduce casualties in case of fire.

Fire alarm equipment automatically detects fires by using heat, smoke or flames generated by fires, and alarms people or occupants in the building by sound devices such as bells or sirens, such as receivers, detectors, transmitters, It consists of a sound device.

The receiver classifies the fire protection object for each boundary zone, receives a signal from a detector or a transmitter in an arbitrary zone, indicates a place where a fire has occurred, and generates an alarm through an acoustic device, such as a P-type receiver, an R-type receiver, GP and GR receivers are available.

The P-type receiver is a method of connecting a detector, a transmitter, a bell, and the like by a solid line, and is widely used in small and medium-sized buildings. P-type receivers are classified into 1st class and 2nd class, but rarely use 2nd class, and 1st class must be installed in building more than 4 stories.

In addition, the R-type receiver connects a repeater between the detector, the transmitter, and the receiver to receive a signal from the detector or the transmitter as a unique signal. Generally, it is used when there are many lines or when you want to centrally manage a large number of buildings in a ward, or when there is a plan to increase the number of lines.

In addition, GP and GR type receivers are gas leak detection functions added to P type or R type receivers.

The detector is divided into thermal, smoke and flame according to the detection principle, and the thermal sensor is divided into functional differential, constant temperature, and compensation. According to the method of use, it is divided into spot type and distributed type, and it is divided into air tube type, thermocouple type, and thermal semiconductor type according to the detection method or element.

The sound system generally uses 'bell', which is distinguished in volume and tone from the noise of other equipment, but the standard terminology may be used as a 'sound device' other than the bell. Other than the bell, electronic circuits are used, and they operate by transmitting a certain frequency. Acoustic devices are classified into main acoustic devices installed near the receiver and earth acoustic devices installed in the building premises, such as stairs, corridors, and aisles. There is a function to notify.

The transmitter transmits a signal to a receiver by operating a push button by a person who finds a fire before the detector is operated, and a P-type transmitter is used in Korea.

The P-type transmitter is a manual signal transmitter that is divided into 1st class and 2nd class according to whether there is a telephone communication device with the receiver, and is classified into outdoor type and indoor type according to the presence or absence of waterproofness.

3 is a view schematically showing a P-type transmitter and receiver in a general fire alarm.

Reference numeral 10 is a P-type transmitter arranged on each floor, and a predetermined number is provided for each boundary area. Here, the boundary area means the area where one line of the automated fire detection system can effectively detect a fire, and the standard is in accordance with Article 82 of the Fire Protection Standards Rules.

The transmitter 11 is composed of a telephone terminal 13 that allows the person who finds a fire to contact the operation button 12 for sending a fire signal to the receiver 20 and a telephone. An indicator 22 for indicating the operation of the transmitter 10 of the floor, an ammeter 23 for indicating the amount of power supply current of the receiver, and a function button for selecting various operations are provided.

Here, the operation button 12 is installed in a non-push (Non Push-Pull) method, so that the user can continue to emit an alarm sound even after avoiding the seat after pressing the button, of the operation button 12 To release it, the operation of the fire receiver must be taken seriously.

However, the automated alarm system is often operated not only at the time of fire but also by the mischief or malfunction of the children, and emits an alarm sound. There are many cases where people have been disguised in the form of gastrointestinal installations, noisy when the alarm bell rings, and deliberately stopped to prevent surprises by many people. Since the decomposition of the general public is difficult to continue to generate noise has a problem that gives a lot of inconvenience to the user.

Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to provide a fire alarm transmitter and a fire alarm having a recovery function that is easy to recover from the transmitter even when the fire alarm is not pressed in the receiver. In providing a receiver.

The configuration of the present invention for achieving the above object, in the fire alarm device equipped with a receiver to generate an alarm sound to the sound device by receiving an alarm signal when detecting or detecting a fire, in parallel with the return button of the receiver A plurality of connected release buttons, an operation button for outputting a fire alarm signal to the fire alarm receiver, and a telephone terminal for telephone connection to the fire alarm receiver.
