Description

An alarm for automatic fire alarm system

Technical field

The utility model relates to the technical field of alarms, specifically an alarm for an automatic fire alarm system.

Background technique

An alarm is an electronic product that is used to prevent or prevent the consequences of an event. It uses sound, light, air pressure, etc. to remind or warn us that we should take certain actions. The application number is "CN213876983U". "An automatic fire alarm system" has solved the problem that in order to prevent flying insects from entering the smoke alarm from the smoke inlet, it is usually necessary to install an insect-proof net at the smoke inlet. Although the insect-proof net isolates flying insects, dust will remain in the smoke alarm after long-term use. It will accumulate on the insect-proof net, causing blockage and affecting the normal detection of smoke. After further searching, it was found that "an automatic fire alarm system" disclosed in the application number "CN113256932B" has specific technical structure settings. It effectively solves the problem that the automatic fire alarm system cannot perform actual fire analysis at the fire warning site, and cannot select appropriate fire response measures based on the actual fire situation at the fire warning site. It is prone to excessive fire protection measures, resulting in waste of resources and losses, etc. Technical shortcomings, but in actual use, alarms with similar structures for automatic fire alarm systems still have many defects, such as: they do not have the function of escape lighting. When a fire occurs, there is not enough lighting, resulting in personnel being unable to see corridors and passages clearly. , doors and windows, etc., making it impossible to escape quickly and safely, reducing the efficiency and safety of personnel's escape; it does not have the function of actively detecting fire smoke and dissipating heat for the electronic equipment inside the device, resulting in the inability to detect fires in time, delaying people's escape The escape time and the inability of the electronic products inside the device to dissipate heat affect the service life of the device, so it is necessary to install an alarm for an automatic fire alarm system.

The installation cover provides an installation location for the smoke sensor and facilitates staff to access the electronic equipment inside the hood.

Preferably, a buckle is fixedly installed on the top of the housing, and the buckle is mounted with an installation disk through a buckle slot. The device can be installed at the bottom of the installation plate through the buckle and the slot, which facilitates workers to quickly assemble the device and remove the shell for internal inspection and partial replacement, thus achieving the function of convenient disassembly and installation of the device.

Preferably, bolts are provided inside the installation plate, and a wiring port is provided in the middle of the installation plate. Fix the mounting plate on the wall through bolts, and connect the power supply and battery through the wiring port.

Compared with the existing technology, the beneficial effects of this utility model are:

1. Detect smoke through a smoke sensor. The smoke sensor transmits the detected smoke signal to the controller for calculation. The sensor light is controlled to turn on the lighting through the calculation results of the controller. This realizes the function of escape lighting in the event of a fire and provides escape. Provides sufficient lighting for personnel to enable escape personnel to escape quickly and safely, improving the efficiency and safety of personnel escape.

2. The fan is powered on to generate wind, which can transport the air to the inside of the hood through the smoke inlet. The smoke sensor is used to detect the transported air, achieving the function of actively detecting fire smoke and expanding the detection range of fire smoke. When there is no fire, the wind generated by the fan can dissipate heat for the electronic equipment running inside the device, and the smoke exhaust vent will be used to discharge the heat energy of the electronic equipment inside the device, realizing the function of dissipating heat for the electronic equipment inside the device and improving The service life of the device.
