The correct installation of four common detectors

First, the door magnetic detector installation requirements 1, door magnetic detector installed in the door you need to be controlled by the door or window frame, that is, the door magnetic detector (main parts, vice parts) fixed on the door and window frame.

2. The false alarm rate has a great relationship with the installation location. The recommended installation location should be a gap of ≤ 2mm between the main part and the subsidiary part.

Second, the wireless infrared detector installation requirements Infrared probe can only be installed indoors, the false positive rate and the installation location has a great relationship, the correct installation location should be 2.0-2.2 meters away from the ground; away from air, refrigerator, stove and other air Sensitive place for temperature changes.

1. The infrared probe should be installed in the corner of the room as far as possible to obtain the best detection range. There should be no screen, furniture, large bonsai or other partitions within the detection range.

2. The infrared probe should be at a certain angle with the walking line in the room. The infrared probe is the least sensitive to the radial movement reaction, and is most sensitive to the tangential movement (that is, the direction perpendicular to the radius). Selecting an appropriate installation location on site is an extremely important step to avoid false alarms for infrared sensors and to obtain the best detection sensitivity.

Third, household gas leaks wireless alarm installation requirements 1, installation and use:

(1) First determine the proportion of combustible gas and air, and then the alarm is fixedly installed in a suitable location within 1.5M from the gas source radius: A. Gas, lighter than air, floating at a high place; B. Natural gas, lighter than air , floating in high places; C. liquefied petroleum gas, heavier than air, deposited in the low;

(2) After the power is turned on, the alarm sounds, and the power light is always on. The function light flashes green and turns off after about 2 minutes, indicating that it has entered the alert state. When a gas leak is sensed, it will be issued."嘀 嘀 嘀 嘀 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警

(3) If the sensor malfunctions, the alarm device will issue a "beep-long sound" and the function light will turn yellow. When the fault is removed, it will automatically enter the alert state.

2. Note:

(1) Do not install outdoors;

(2) Do not install in places with large air flow such as air supply ports, ventilation fans, and doors;

(3) Do not install in a place where the temperature exceeds 10~50°C or is relatively humid;

Do not install where there are objects to isolate the alarm from the gas equipment;

Avoid the use of solid spray adhesives, insecticides, paint binders, and dilute alcohols in the vicinity of alarms;

If the alarm malfunctions, do not disassemble and repair it yourself. You can notify the supplier or nearest agency.

Fourth, wireless smoke alarm installation requirements 1, installation and use: Select a good surveillance area, the alarm is fixed in the monitoring area of ​​the roof or ceiling can be.

2. Note: Do not install outdoors; do not install in places where the air flow, ventilation fan, door, etc. have a large amount of air flow; do not install in areas where the temperature exceeds 10~50°C, or relatively humid; the installation position of the alarm is away from the corner Must be more than 0.75 meters; must be dust-proof and moisture-proof;

3, maintenance: due to dust and other factors will lead to alarm sensitivity decline, it must be frequently tested and maintained; weekly detection of an alarm, press the test key can be; clean the alarm every six months, turn off the power, with Soft brush can sweep dust.

Bottom shutters door,only used at bottom of shutter door.Material thickness:1.5-3mm.
