The chime receiver can be paired with an additional 4\u20135 sensor units or doorbell push buttons.\n\nIt provides 32 chime melodies and 4 adjustable volume levels. <strong><a href=\"https:\/\/kawasan.vn\/en\/product-category\/chuong-cua-chuong-bao-khach\/\">KAWASAN offers a wide range of smart chime and doorbell models.<\/a><\/strong><\/p>\n<figure id=\"attachment_16629\" aria-describedby=\"caption-attachment-16629\" style=\"width: 600px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-16629\" title=\"Can be paired with a push button or sensor unit.\" src=\"https:\/\/kawasan.vn\/wp-content\/uploads\/2026\/10\/2-15.png\" alt=\"C\u00f3 th\u1ec3 k\u1ebft h\u1ee3p v\u1edbi n\u00fat b\u1ea5m ho\u1eb7c \u0111\u1ea7u c\u1ea3m \u1ee9ng\" width=\"600\" height=\"632\" \/><figcaption id=\"caption-attachment-16629\" class=\"wp-caption-text\">Can be paired with a push button or sensor unit.<\/figcaption><\/figure>\n<h2 id=\"C\u00e1ch_th\u1ee9c_ho\u1ea1t_\u0111\u1ed9ng_c\u1ee7a_chu\u00f4ng_c\u1eeda_kh\u00f4ng_d\u00e2y_nh\u01b0_th\u1ebf_n\u00e0o?\"><strong>HOW DOES THE B8A WIRELESS DOORBELL WORK?<\/strong><\/h2>\n<p>When the B8A doorbell push button is pressed, the signal is received and transmitted to the signal receiving unit. The electrical signal is then converted into a radio-frequency signal compatible with the chime receiver installed inside the house.\n\nWhen the chime receiver receives the RF signal, it converts the signal into a control command that activates the chime sound, notifying the homeowner that a visitor has arrived.\n\nIn addition, some devices may also include a flashing light indicator to provide a visual alert, which is particularly useful for people with hearing impairments.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>M\u00e3 s\u1ea3n ph\u1ea9m: B8AT\u00ecnh tr\u1ea1ng:C\u00f2n h\u00e0ng<\/p>","protected":false},"featured_media":28946,"comment_status":"open","ping_status":"closed","template":"","meta":{"_yoast_wpseo_focuskw":"Chu\u00f4ng C\u1eeda B8A","_yoast_wpseo_metadesc":"Chu\u00f4ng c\u1eeda B8A kh\u00f4ng d\u00e2y d\u00f9ng \u0111i\u1ec7n 220V, nh\u1eadn s\u00f3ng RF 433Mh.
