Security monitoring and alarm system installation matters

1. Choose a suitable installation location

Whether the detector can work normally has a close relationship with its surrounding environment. Therefore, choosing a suitable installation location should arouse high attention from all installation personnel.

The optimal installation position of the detector should be determined by the installer according to the actual situation on the site, and there is no fixed plan to follow. Generally, it can be considered from the following aspects:

2. Objects around the detector
(1) The installation site should avoid sources of false alarms:

Avoid installing the detector directly near objects that may cause false alarms, such as cold / heat sources (air conditioners, refrigerators, heating equipment, etc.), fluorescent lamps and vents, etc., as far as possible.

(2) The false alarm factor enters the detection viewing area:

Regardless of whether it is wall-mounted or ceiling-mounted, the detection viewing area should be directed to doors and windows, moving mechanical equipment (fans), fluorescent lights, and cold / heat sources (air conditioners, refrigerators, heating equipment, etc.) False positives are very important. When installing in a building with doors and windows near the street, you should pay more attention to avoid this situation.

Basic principles: 1. Wall-mounted detectors should face indoors to avoid direct installation of doors and windows 2. Ceiling-mounted detectors should be installed as far away from doors and windows as possible to prevent the detection area from running outside 3. Detection of possible false alarms at the edge of the viewing area It is best to reserve protected areas between the factors.

note:

It is forbidden to install the ceiling-mounted detector on the ceiling close to the doors and windows unless the shielding viewing area facing the outdoor is shielded with a sticker in advance.

Is there an obstacle in the detection zone?
Is it possible for the mouse to crawl over from the detector?

note:

When installing, avoid installing the detector with the top view area directly above the shelves, furniture, mirror frames and other objects. Because the mouse may crawl over these objects, it is too close to the detector, resulting in false alarms.

3. Where to install the most sensitive

The most sensitive installation position should be selected according to the characteristics of different detectors.

Fourth, the characteristics of the wall-mounted detector:

When the target walks along the direction of cutting the infrared viewing zone laterally, the detector is the most sensitive; while walking facing or facing away from the detector, the detector's response is the slowest. The detector is the most sensitive when the target walks in the direction of parallel microwaves.
