Door Bells

A door bell is a signaling device that sounds an audible alert indoors when the button at the entrance is pressed, announcing that a visitor has arrived. It is used on the doors of homes, offices, shops and gardens; wireless models are installed without touching the installation where cable cannot be run. This category contains Cata and ACK wireless bells with remote control, a Cata kinetic-energy bell and NisaLuce ding-dong and single-tone door bells; the products have values such as 100 m and 150 m remote control range, 38 melodies and IPX3 protection rating. Choose the bell by wired or wireless installation, a remote control range that covers the distance between the button and the receiver, the melody count and sound level, the IP rating if the button will be outdoors, and the supply method. For wireless bells the manufacturer range is generally given for open space; obstacles such as walls and metal doors shorten the distance. In a kinetic bell, the button sends the signal with the energy it generates from the pressing motion and needs no battery. A door bell only gives a call signal; it cannot replace an intercom system that lets you talk with the visitor and open the door.
