Where is the application of fire heat detectors ?

We all know that smoke detectors and fire optical heat detectors are used to detect whether a fire has occurred. Smoke detectors monitor the concentration of smoke to prevent fires. Temperature heat detectors detect fires through changes in temperature. According to the different detection methods, the application places of the two fire detectors is still slightly different. Here we focus on the application places of optical heat detectors.

The fire optical heat detector has two alarm methods of rate-of-rise alarm and fixed temperature alarms. The temperature sense of the alarm at a fixed temperature of 57 degrees Celsius is suitable for all places where fire will occur. When the temperature reaches 57 degrees Celsius, it indicates that the fire has occurred or is occurring or is about to happen; It is noteworthy that Pay attention to the place where the temperature changes rapidly, it is better to choose a heat detector with Rate-of-rise alarm whose temperature rising rate>8℃.

Temperature-sensitive optical heat detectors: A temperature-sensitive maintenance area is 20 to 30 square meters
Where smoldering occurs or a fire cannot be reported in time, a optical heat detector should not be selected
Where one of the following conditions is met, a temperature-sensitive fire heat detector should be selected:
1) The optical heat detector is suitable for relative humidity often greater than 95%;
2) Smokeless fire;
3) There is a lot of dust;
4) Smoke and vapor stay under normal conditions;
5) Kitchen, boiler room, generator room, drying workshop, etc .;
6) Smoking room, etc .;
7) Other halls and public places that are not suitable for installing smoke detectors

Is it important to clean the domestic smoke detector frequently?

Speaking of domestic smoke detectors, it is a common alarm device in our daily life. It plays a certain alarm role in daily fire prevention and helps reduce property damage. So is it important to clean the smoke alarm frequently?

If the domestic smoke detector sounds continuously, then there may be too much dust in the alarm, and it is time to consider replacing the alarm or cleaning it. When cleaning the alarm, close the end of the vacuum cleaner near the opening around the alarm and vacuum one by one. In this way, the dust accumulated on the alarm can be completely removed.

It is very necessary to clean the domestic smoke detector regularly. The smoke alarm has some small sieve-like shelters around the induction center to prevent small bugs and dust from entering the induction center. But dust can accumulate around the shelter, thereby delaying the movement of the air. Cleaning the alarm is easy. Just use a vacuum cleaner to suck out the air outside the alarm, and clean it at least once a year.

Do you know how a smoke optical alarm works?

smoke optical alarm realize fire prevention by monitoring the concentration of smoke. Our smoke detectors use photoelectric (optical)smoke sensors. Photoelectric smoke sensors are advanced technology, stable and reliable sensors and are widely used in various Fire alarm system

The smoke moved up and reached the ceiling. Smoke optical alarm detect fires through smoke. When you don't see the flame or smell the smoke, the smoke detector already knows. It works non-stop, 24 hours a day, 365 days a year. At the time of the alarm, it made a squealing noise until the smoke dispersed. In a real fire it worked until it was burned.

       

The photoelectric sensor measures the concentration of smoke through a beam of light and a light sensor. When the device was designed, the beam was deviated from the sensor. When the smoke enters the induction chamber, the smoke particles will scatter part of the light beam onto the sensor. As the concentration of smoke gradually increases, more light beams will be scattered on the sensor. When the beam reaching the sensor reaches a certain level, the buzzer will sound. so that means the smoke optical alarm started working...

what is the working principle of the iron magnetic contact sensor ？

The iron metal magnetic contact sensor is a small accessory can used to monitor the state of the iron door. It is mainly divided into two parts: part with leads, which is installed on a fixed door frame, and the leads are connected to the controller; the second part does not have The lead is a magnetic body with a polarity different from that of the lead. It is installed on the movable door leaf and is aligned with the lead.

 the working principle of the iron magnetic contact sensor : There is a small reed switch in the door sensor with lead wire. When the door is not in direct contact with the wireless part (the door is open), the reed switch is normally open. The output signals of the two leads are normally open. Dry contact signal; when the door is closed, the two parts of the door magnet are facing each other, and the reed switch of the lead part is closed by the action of the magnetic field. At this time, the output signals of the two leads are normally closed dry contact signals. By switching the state of the door sensor, you can easily monitor whether the door is open or closed.

When installing, you only need to open a circular hole of corresponding size in the corresponding position of the door frame and door leaf, and then install the door magnet into the hole

Home security door sensors operation principle

The door sensor system is a safety alarm system. If the home security door sensors not noticed, the door sensor will not be easy to see. The so-called home security door sensors is actually a door sensor switch consisting of two parts: the smaller part is a permanent magnet that is used to generate a constant magnetic field. The larger is the door magnet body, which has a normally open type inside. 

 
When the permanent magnet and the reed are close to each other (less than 5 mm), the door magnetic sensor is in a waiting state. When the permanent magnet leaves the reed for a certain distance, it is always open.

The magnet and the reed switch are respectively installed in the door frame (window frame) and the door leaf (window leaf), and are basically embedded (also surface-mounted), so people in the industry are generally not aware of these. 

Open the split door and the outer window, look at the top of the split door door frame and the window frame of the outer window, and you can see the round and generally white components. In fact, this is the so-called door magnet,we also called home security door sensors.

How to install a wireless door contact sensor ?
