Precautions For Installation Of Four Common Detectors
1. Installation requirements for door magnetic detectors.
The door magnetic detector is installed on the door frame of the door or window you need to control, that is, the door magnetic detector (main part, auxiliary part) is fixed on the frame of the door and window.
2. 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.
Wireless infrared detector installation requirements:
Infrared probes can only be installed indoors, and 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 air temperature changes.
a) The infrared probe should be installed in the corner of the room as far as possible to obtain the best detection range, and there should be no partitions, furniture, large bonsai, or other partitions within 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, and most sensitive to tangential movement (ie, the direction perpendicular to the radius). Choosing a suitable 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 leakage wireless alarms:
Install and use:
a. First determine the specific gravity of combustible gas and air, and then install the alarm at a suitable position within 1.5M of the gas source radius: A. Gas: lighter than air, floating at high places; B. Natural gas: lighter than air, Floating at high places; C. LPG: heavier than air, deposited at low places;
b. After the power is turned on, the alarm will sound "Di", and the power light is always on, the function light is flashing green, and goes out after about 2 minutes, indicating that it has entered the alert state. When gas leakage is detected, it will emit "Di". , Di" alarm sound, and the function light flashes red at the same time, after the alarm system is cleared, it will automatically enter the alert state;
c. If the sensor fails, the alarm will give out a long beep of "Di -", and the function light will light up in yellow. After the fault is eliminated, it will automatically enter the alert state.
4. Wireless smoke detector installation requirements:
How to install the detector correctly
a. Installation and use:
● Select the monitoring area and install the alarm on the roof or ceiling of the monitoring area.
b. Notes:
● Do not install it outdoors;
● Do not install in places with large airflows such as air supply ports, ventilation fans, and doors;
● Do not install in a place that exceeds 10 ~ 50 ℃, or is relatively humid;
● The installation location of the alarm must be greater than 0.75 meters from the corner of the wall;
● Must be dust-proof and moisture-proof;
c. Maintenance:
● Due to factors such as dust, the sensitivity of the alarm will decrease, so it must be tested and maintained frequently:
● To test the alarm once a week, press the test button;
● Clean the alarm once every six months: turn off the power supply and clean the dust with a soft brush.
