The additional width and depth of these sinks allows plenty of room for soaking dishes, large pots and pans, and other hard-to-clean items, such as grill grates, stock pots, and baking sheets.

Typically, a farmhouse sink won`t include pre-drilled holes for a faucet. While this may seem like a bad thing on the surface, this actually provides homeowners with a bit more flexibility in choosing the best faucet for their needs.

1. According to the instructions to determine the normal installation angle Mounting height is not arbitrary, it will affect the sensitivity of the detector and the effect of preventing pets. Imagine a detector mounted at a height of 2M and a height of 2.5. When the moving object moves from the ground, the frequency of cutting the bright area and the dark area is different.
2. Should not face the glass doors and windows Passive infrared detectors are facing the glass doors and windows, there will be two problems: First, white light interference, obviously PIR has a strong suppression of white light, but after all, is not 100% inhibition. So avoid facing the glass doors and windows, you can avoid strong light interference. The second is to avoid complex environmental disturbances outside doors and windows, such as crowd movements and vehicles.
3. It is not appropriate to have a close relationship with the change of temperature for the passive infrared detectors of cold and hot vents or cold and heat sources. Hot and cold vents and cold and hot sources may cause false alarms. For some low-performance detectors, air convection through windows and doors sometimes causes false alarms.
4. It is not right for the easily swinging object http://. . Com/product/infrared_detector/
Easy-to-sweep objects will make microwave detectors work and therefore may also cause false alarms. Pay attention to the illegal invasion route.
The purpose of installing the detector is enough to prevent criminals from intruding. Before determining the installation location, the main population of the building must be considered. In fact, we have prevented entrances and exits and intercepted illegal intrusions. This has achieved our goal.
