What is the working principle of the alarm system?

The working principle of the smoke alarm is that the infrared beam of the infrared emitter is scattered by smoke particles, and the intensity of the scattered light is directly proportional to the concentration of the smoke, so the strength of the infrared beam received by the photosensitive tube will change, convert it into an electrical signal, and finally convert it into an alarm signal.

Abstract: The fire alarm system is linked by different systems, so in principle, the different principles of the system are also different. For example, the working principle of the smoke prevention system is that when a disaster occurs, the operating mechanism automatically opens the air valve under the action of the smoke-sensitive alarm electrical signal, and activates the fan and smoke exhaust fan. Wait.

The alarm process of the automatic fire alarm control system is to convert it into an electrical signal through the fire detector, transmit it to the fire alarm controller, and then alarm. The automatic fire alarm system is made ofIt is composed of trigger device, fire alarm device, linkage output device and other auxiliary functions.

The alarm detector is composed of sensors and signal processing, which is used to detect the intrusion behavior of intruders. It is a device composed of electronic and mechanical components, which is the key to the anti-theft alarm system, and the sensor is the core component of the alarm detector.

design steps of the alarm system

1. Central processor: data collection and control of docking terminal equipment, master the on-site fire data and send information to the firefighter supervision department in time. ( 3) Monitor: It is used to display fire alarm information, identify the location, type, level, etc. of the fire alarm, and control the sound of the sound and light alarm.

2. Roots are neededCalculate the specific number of gas detection and alarm equipment used according to different detection areas, and select the gas detection and alarm controller host according to this specific number. After these are confirmed, they need to be installed manually. Specifically, it is necessary to go through the line and link the detection equipment. After testing, it can be put into use.

3. The system design should be standardized and practical. The design of the anti-theft alarm system must be based on the actual survey of the site, and according to the environmental conditions, the object of prevention, the scale of investment, the maintenance and the method of receiving the police and other factors.

intelligent monitoring system and alarm system

pulsed electronic fence: a kind of intelligent perimeter blocking alarm system, equivalent to the perimeter A "tansible" electronic barrier is formed on the wall, increasing the height of the wall and making it impossible for outsiders to invade.

Alarm and linkage function: Install door magnets and window magnets to prevent illegal intrusion. The management system can obtain signals through the alarm controller installed in the household room to quickly receive the police. The alarm linkage control can automatically turn on the indoor lighting, activate the alarm, etc. at the same time as the system sends alarm information to the outside.

Intelligent monitoring equipmentThe monitoring system includes lenses, cameras, brackets, power supplies, shields, gimbals, decoders, code converters, hard disk recorders, matrices and monitors and other equipment. The alarm system of alarm equipment includes front-end detectors and back-end devices.

This article will introduce a variety of functions of the intelligent security system, including alarm and linkage function, emergency help function, alarm management display function, preset alarm function, set; evacuation linkage control, post-police control processing, etc.

What parts does the fire alarm system consist of?

1. Sensors and detectors: Sensors and detectors of the fire alarm system are one of the most important components of the system. The function of the sensor is to detect abnormal conditions such as fire or smoke in the environment, and convert these signals into electrical signals for the system to process.

2. Fire detector is an important part of the automatic fire alarm system and the key to the performance of the whole system. The manual alarm button is a device that generates fire alarm signals manually, and it is also one of the indispensable components of the automatic fire alarm system.

3. Trigger device trigger device: fire detector and manual alarm button fire detector fire detector is an important part of the automatic fire alarm system and the key to the performance of the whole system. The manual alarm button is a device that manually generates fire alarm signals, and it is also an indispensable part of the automatic fire alarm system.

4. It is generally composed of trigger device, fire alarm device, alarm device, power supply and other linkage devices with auxiliary control functions.
