Smoke detector are used to monitor the concentration of smoke to achieve fire prevention, ring smoke detector internal photoelectric smoke alarm principle, photoelectric smoke sensor is a technologically advanced, stable and reliable sensor, is widely used in a variety of fire alarm systems, performance is far better than gas-sensitive resistive fire alarms. It is suitable for smoke monitoring in indoor environments such as homes, shopping malls, hotels and warehouses.
Leiz International smoke detector are designed on the principle of photoelectric smoke detection, with built-in smoke sensors and photoelectric smoke detectors. Smoke moves upwards, and as it rises to the bottom of the ceiling and enters the interior of the alarm, smoke particles scatter part of the light beam onto the sensor. When the beam of light scattered on the sensor reaches a certain level, a buzzer sounds an alarm, at the same time as the sensor converts the light signal into an electrical signal and transmits it to the automatic fire alarm system to indicate a fire in the area.
Stand-alone firex smoke detector have the characteristics of accurate measurement, responsiveness and high stability; in line with the fire GB4715-2005 standard, ceiling-mounted, no need for commissioning, able to 360 ° all-round detection of fire; the use of patch technology can be resistant to EMI, RFI interference, once the “capture” to the object burning “signal”, the signal will be uploaded to the fire system, to ensure the continuity of information transmission.
According to statistics, the proportion of deaths, injuries and property damage caused by fires has been greatly reduced with the introduction of Smoke co detector. The National Fire Protection Association reports that in the event of a fire in a home with the recommended number of smoke alarms installed, the occupants of the home will have a 50% greater chance of escape than if the home were not installed, so it is essential to have an alarm in the home.
The correct installation of a smoke alarm is the first step in ensuring fire safety, so how should it be done? The following is a list of some of the most common methods of installing the 485 signal cable in your home.
Fix the installation base to the ceiling with screws. 4.
After installation, it is recommended to carry out a simulated fire test to test whether the alarm can be used normally.
Installation Notes
1. The alarm should be dustproof and the dust cover should not be removed until the project has been officially put into use.
2、When installed on the roof, if installed on an inclined or man-shaped roof, the alarm should maintain a certain distance from the roof Whenever the slope is less than 30°, a distance of 0.2m is appropriate; when it is greater than 30°, a distance of 0.3m~0.5m is appropriate.
3, do not install in places where smoke normally remains,Smoke alarm are strongly sensitive to smoke, so for places such as the kitchen, smoking, etc., which are prone to smoke, the alarm is likely to be false.
4. Avoid installation in places with large dust, water mist, steam, oil mist pollution and corrosive gases.
5. The temperature and humidity of the working environment of Hard wired smoke detectors should not exceed -10~50℃, avoid installing them in places where the relative humidity is greater than 95% and the ventilation speed is greater than 5m/s.
6. Avoid installation in close proximity to fluorescent light fittings.
7. It is recommended that a mock fire test should be carried out every six months to test whether the alarm is working properly.
8, Never mask Home depot smoke detectors with tape, plastic bags, etc.!
