1. The requirements on magnetic door sensor installation:
a. The door sensor detector is installed on the door frame of the door or window you need to control, that is, the door sensor detector (main part, auxiliary part) is fixed on the frame of the door and window.
b. The false alarm rate has a great relationship with the installation position. The recommended installation position should be the gap between the main part and the auxiliary part ≤ 2mm.
2. Wireless infrared detector installation requirements:
The infrared probe can only be installed indoors. The false alarm rate has a great relationship with the installation location. The correct installation location should be 2.0-2.2 meters away from the ground; away from air conditioners, refrigerators, stoves and other places sensitive to changes in air temperature.
a. The infrared probe should be installed in the corner of the room as far as possible to obtain the most ideal detection range. There should be no screens, furniture, large bonsai or other partitions in the detection range.
b. The infrared probe should be at a certain angle to the indoor walking line. The infrared probe is the least sensitive to radial movement, while it is most sensitive to tangential (that is, the direction perpendicular to the radius) movement. Choosing an appropriate installation location on site is an extremely important part of avoiding false alarms of infrared probes and obtaining the best detection sensitivity.
3. Installation requirements for household gas leak wireless alarms:
a) Installation and use:
i. First determine the specific gravity of combustible gas and air, and then install the alarm at a suitable position within a radius of 1.5M from the gas source: A. Gas: lighter than air, floating in a high place; B. Natural gas: lighter than air, Floating in high places; C. Liquefied petroleum gas: heavier than air and deposited in low places;
ii. After the power is turned on, the alarm beeps once, and the power light is always on, the function light flashes green, and then goes out after about 2 minutes, indicating that it has entered the alert state. When a gas leak is detected, it will emit a beep. , "Beep" alarm sound, and the function light flashes red at the same time, it will automatically enter the alert state after the alarm is eliminated;
iii. If the sensor fails, the alarm will beep for a long time, and the function light will be yellow and bright. After the fault is removed, it will automatically enter the alert state.
b) Matters needing attention:
i. Do not install outdoors;
ii. Do not install in places with large air flow such as air inlets, ventilating fans, and doors;
iii. Do not install in a place that exceeds 10 ~50°C or is relatively humid;
iv. Do not install in a place where there are objects that separate the alarm from the gas equipment;
v. Avoid using a large amount of solid hair spray, insecticide, paint adhesive, diluted alcohol, etc. near the alarm;
vi. If the alarm fails, do not disassemble and repair it by yourself, but notify the supplier or the nearest agency to deal with it.
4. Wireless smoke alarm installation requirements:
The correct installation method of the detector
a. Installation and use:
Select the monitoring area and install the alarm on the roof or ceiling of the monitoring area.
b. Matters needing attention:
i. Do not install outdoors;
ii. Do not install in places with large air flow such as air inlets, ventilation fans, and doors;
iii. Do not install in a place that exceeds 10 ~50°C or is relatively humid;
iv. The installation position of the alarm must be greater than 0.75 meters from the corner of the wall;
v. Must be dust-proof and moisture-proof;
3. Maintenance:
a. Due to dust and other factors, the sensitivity of the alarm will decrease, so it must be tested and maintained frequently:
b. Check the alarm once a week, just press the test button;
c. Clean the alarm once every six months: turn off the power and use a soft brush to clean the dust.
