Smart home system bus wiring and precautions

Wiring, embedding, and line verification

The wiring layout is usually buried in a buried manner, and the communication bus wiring requirements are separated from the strong electricity.

For weak boxes and audio/video junction boxes, refer to their actual size for excavating the wall.

After the line is laid, the line calibration must be performed first to avoid the occurrence of intermittent or short circuit in the line.

Installation wiring considerations

(1) The power must be disconnected before the strong electrical connection, and the strong electricity is forbidden to touch the bus crystal head and cause product damage.

(2) The load connection method of the smart switch is the same as the traditional switch.

(3) The communication bus uses 4x2x0.5mm2 8-core broadband communication twisted pair. The smart product is connected to the communication bus using a plug connector. The bus header is lined by the same standard broadband cable (568B).

(4) The smart transponder is installed on the opposite side of the household appliance or diagonally opposite (preferably about 2m off the ground, or with the position of the intelligent switch); or the ceiling-mounted installation.

(5) Adjustable lamps (such as incandescent lamps) should adopt thyristor-type intelligent switch control; non-adjustable lamps (such as fluorescent lamps, energy-saving lamps) must use relay-type intelligent switch control.

(6) The centralized driver should be installed on the rail in the strong box to facilitate future maintenance.

(7) For the installation of the bottom box using the national standard 86mmx86mm bottom box or 146x86 bottom box, the required depth is not less than 45mm.

(8) Keli House's dimming module is only suitable for dimming incandescent lamps with a rated voltage of AC 220V, and can't dimmable lamps such as estuary lamps or energy-saving lamps, and it can't be used for lamps that use electronic transformers for step-down ( Dimming is performed for spotlights or downlights with a filament voltage of 12V, but spotlights or downlights with a rated voltage of 220V for the filament can be dimmed.

(9) According to the division of the spotlight filament voltage, the spotlight has two specifications of AC 220Y and 12Y. Among them, the spotlight whose AC voltage is 12V is mostly powered by the electronic buck, and cannot be used for dimming, otherwise it is easily damaged by the electronic drop. Voltage regulators, if you want to dimming need to use the filament voltage of AC 220V spotlights.
