USA customer place the mass order of anti-insect screen mesh for their Wireless Interconnected Smoke Detector

 is one of the fire alarm devices that is widely common used in today‘s life with the main function of recognizing and giving fire and explosion warnings.


               features of the anti-insect screen for fire alarm

Anti-insect screen for fire alarm has nice design to have the ability to sense and detect smoke - one of the most effective ways to warn of a fire today, most screens will send a signal to the alarm center on fire. Some screens are for home use, which can sound an alarm on the spot when there is a fire.

Smoke sensors typically come in a disc-shaped plastic housing approximately 100 mm (4 in) in diameter, or 150 mm (6 in) in diameter, with the common connection.

Photoelectric gas sensors and ionization smoke sensor

Regarding smoke detection technology, smoke sensors divide into two types:

• First, photoelectric gas sensors
• Second, ionizing smoke sensors

In particular, the sensor difficult to use photoelectric technology prefers and more popular application than the ionization smoke sensor. The photoelectric smoke sensor designs to detect smoke using a small light source. A lens focuses the light into a beam and a photoelectric sensor, is angled to the infrared beam.

All of the above components are placed in an optical chamber, also known as a smoke chamber. The optical chamber has a special structure, so that outside light cannot enter, but smoke can easily enter. The outside of the optical chamber has anti-insect screen for fire alarm, to prevent dust and insects from getting inside.

Working principle of anti-insect screen for fire alarm

In the normal case, the light beam generated by the infrared illuminator travels in a straight line and does not reach the optical sensor head.

Anti-insect screen for fire alarm detects smoldering fires well. Optical smoke sensors respond more slowly than ionic sensors to rapidly spreading fires. Today, some modern optical smoke sensors have very high sensitivity. It covers the range of ion smoke sensors, and can completely replace ion sensors.

Common applications of anti-insect screen for fire alarm

The most common application of the screen is for installation in room smoke detectors (ceilings), duct smoke detectors (such as ducts) for the purpose of detecting and detecting smoke and providing alarms. Warn as soon as possible;

• Firstly, prevent fire and explosion in buildings
• Secondly, apartments
• Thirdly, commercial centers
• Fourthly, in industrial parks
• Fifthly, factories
• Sixthly, factories, etc

Anti-insect screen for fire alarm systems are designed for early detection of;

• Fire
• Moreover, smoke
• Flames
• Gas
• Furthermore, carbon monoxide giving us time to evacuate safely.

Early detection is also key to protecting life and property and giving emergency responders enough time to provide timely assistance while a fire or toxic gas is still small.

In this article, we will delve into the structure, operating principle and common automatic fire alarm systems on the market.

Structure of the anti-insect screen for fire alarm system

Fire alarm systems are designed to alert us in an emergency so we can take action to protect ourselves, our families, our employees and everyone else.

• Protection mechanism: detection of fires, smoke, sudden temperature rise, leakage of toxic gas, gas, carbon monoxide.
• Similarly, warning mechanism: siren, flashing lights, emergency call.

Construction of automatic anti-insect screen for fire alarm system

An anti-insect screen for fire alarm system consists of 03 main components which are the fire alarm center, input sensor and output warning device. The central fire alarm cabinet design in the form of a cabinet has a backup battery and has phone SIM modules for emergency dialing.

Construction of fire alarm system

1. Sensor (initiating devices): is a system of sensor probes that are responsible for detecting fires or smoke. Includes smoke detector, heat detector, gas detector, carbon monoxide detector and emergency push button. Furthermore, the sensor probes will be wired to the fire alarm center.
2. Fire alarm center (central processing unit): receiving, analyzing and processing signals from incoming sensor probes.
3. Loudspeakers, fire alarms (output devices): are fire alarm devices such as fire sirens, fire alarm loudspeakers, and emergency telephone dialers.
4.

• Step 1:When the sensors detect a fire, increase in temperature, smoke or toxic gas... they immediately send a signal to the central fire alarm cabinet. Similarly, the same thing happens if the user presses the emergency button.
• Step 2: Fire alarm control panel (FACP) is the main control component of fire alarm devices. When receiving the fire alarm signal from the detector or the emergency button, the fire alarm cabinet will send a signal to the emergency alarm device (horn, light).
• Step 3:Alarm devices include:
  • Fire sirens, fire loudspeakers, flashing lights, sirens:warn people to evacuate.
  • Emergency dialing module:make a call to the functional force (fire 114) or to the person in charge to handle it.

Types of automatic fire alarm systems

Today‘s manual anti-insect screen for fire alarm systems is almost no longer common, because their limitation is having someone on duty 24/7 to press the fire alarm button when they detect a fire. Moreover, today all fire alarm systems are kind of fire alarm systems automatically.

Automatic fire alarm system is easy to divide into 04 main types:

• Conventional fire alarm systems
• Addressable Fire Alarm Systems
• Intelligent fire alarm system
• Wireless fire alarm system

We‘ll look at each type:

How does conventional fire alarm system work?

The physical cable will connect the sensor probes and the emergency push button. The signal comes to the fire alarm control panel.

Push buttons and sensor probes will be arranged in each Zone cluster to determine which Zone is alarming. Each Zone will correspond to 1 indicator light on the control panel.

When installing anti-insect screen for fire alarm, we divide the building into many small Zones and the fewer detectors each Zone has, the more accurate the location of the alarm will be.

This is very important for building management or homeowners when it is necessary to know exactly which “Zone” is experiencing a fire problem to promptly respond.

What is an addressable fire alarm system?

Addressable fire alarm system pinpoints the exact location of a fire, explosion, fire or toxic gas incident. The principle of an addressable fire alarm system is similar to a conventional fire alarm system.

The only difference of an addressable fire alarm system knows the exact location of which location is triggering the alarm (instead of just generalizing by zone area like a conventional system).
