I have one by the door, one at the back of the house and one upstairs. Exactly what I wanted. Bing-Bong the door-bell works... Bought for my partially deaf mum. Very load but good. Recommend putting at eye level an not too high or deaf my not always notice the bright blue light. worked straight away with my current bell so I'm happy
Bought this to be placed upstairs as the main Chime (permanently plugged in the Lounge down stairs) wasn't loud enough to be heard upstairs. Paired easily and makes the doorbell unmissable now! We were initially pleased with this item. We did not really like the sound when this bell was linked to our favourite sound for the main doorbell, but it could certainly be heard... very please with this extra door bell. it worked first time and is very useful. Excellent addition to my exsisting door bell very loud. Fast delivery and packed well. This article is about auditory signals for doorways.

Doorbell from 1884 in Andrássy Avenue, Budapest Antique mechanically operated shop doorbell A doorbell is a signaling device typically placed near a door to a building's entrance. When a visitor presses a button the bell rings inside the building, alerting the occupant to the presence of the visitor.
Although the first doorbells were mechanical, activated by pulling a cord, modern doorbells are electric — they are actuated by an electric switch. William Murdoch, a Scottish inventor, installed a number of his own innovations in his house, built in Birmingham in 1817; one of these was a loud doorbell, that worked using a piped system of compressed air.[1] A precursor to the electric doorbell, specifically a bell that could be rung at a distance via an electric wire, was invented by Joseph Henry around 1831.[2] By the early 1900s, electric doorbells had become commonplace. In most wired systems, a button on the outside next to the door, located around the height of the doorknob, activates a signaling device (usually a chime, bell, or buzzer) inside the building. Pressing the doorbell button, a single-pole, single-throw (SPST) pushbutton switch momentarily closes the doorbell circuit. One terminal of this button is wired to a terminal on a transformer. A doorbell transformer steps down the 120 or 240-volt AC electrical power to a lower voltage, typically 10 to 20 volts.
The transformer's other terminal connects to one of three terminals on the signaling device. Another terminal is connected to a wire that travels to the other terminal on the button. Some signaling devices have a third terminal, which produces a different sound. If there is another doorbell button (typically near a back door), it is connected between the transformer and the third terminal. The transformer primary winding, being energized continuously, does consume a small amount (about 1 to 2 W) of standby power constantly; systems with lighted pushbutton switches may consume a similar amount of power per switch.[4] The tradeoff is that the wiring to the button carries only safe, low voltage isolated from earth ground. A common signaling device is a chime unit consisting of two flat metal bar resonators, which are struck by plungers operated by two solenoids. The flat bars are tuned to two pleasing notes. When the doorbell button is pressed, the first solenoid's plunger strikes one bar, and when the button is released, a spring on the plunger pushes the plunger up, causing it to strike the other bar, creating a two-tone sound ("ding-dong").
If a second doorbell button is used, it is wired to the other solenoid, which strikes only one of the bars, to create a single-tone ("ding") sound. More elaborate doorbell chimes play a short musical tune, such as Westminster Quarters. Doorbells for hearing-impaired people use visual signaling devices — typically light bulbs — rather than audible signaling devices. Fully battery-powered wired models are also common, either using a two-bar design or an electric bell. These do not consume standby power, but require the user to change the batteries, which are usually large primary cells located in the bell box. In recent decades, wireless doorbell systems that do not require wall wiring have become popular. The doorbell button contains a built-in radio transmitter powered by a battery. When the button is pushed, the transmitter sends a radio signal to the receiver unit, which is plugged into a wall outlet inside the building. When the radio signal is detected by the receiver, it activates a sound chip that plays the sound of gongs through a loudspeaker—either a two-note "ding-dong" sound or a longer chime sequence such as Westminster Quarters.
To avoid interference by nearby wireless doorbells on the same radio frequency, the units can usually be set by the owner to different radio channels. In larger metropolitan cities, a trend has developed over the past decade that uses telephone technology to wirelessly signal doorbells as well as to answer the doors and remotely release electric strikes. In many cities throughout the world, this is the predominant form of doorbell signalling. As with wireless doorbells, musical doorbells have also become more common. Musical and continuous power doorbells serve as an attempt to bridge the gap between newer digital circuitry and older doorbell wiring schemes. A major difference between the standard setup of a wired doorbell and a musical doorbell is that the musical doorbell must maintain power after the doorbell button is released to continue playing the doorbell song. This can be achieved in one of two ways. For simple single-pole, single-throw doorbell buttons, the chime device employs a rectifier diode and ballast capacitor at the voltage input stage of the circuit.
Upon pressing the doorbell button, power is connected through the rectifier diode or series of rectifier diodes called a full wave rectifier, which allows the current to flow in only one direction, into the ballast capacitor. The ballast capacitor charges at a rate far greater than the rest of the circuit needs to complete a given song. Once the button is released, the capacitor retains the charge and maintains power for a short duration to the rest of the circuit. For mixed wireless and wired input doorbells, a special doorbell button is needed to maintain power continuously to the doorbell chime. The circuit is similar to the one above, except that the rectifier diode is now moved into the doorbell button housing. Pressing the doorbell button allows both negative and positive sides of the AC power signal to flow into the circuit, while releasing the button only allows either the positive or negative side to flow into the circuit. By differentiating the full and half wave signals, the doorbell is able to function as it does in the previous wired case, while also providing continuous power to the doorbell for other purposes, such as receiving wireless doorbell button input.
