Bla Bla Bla *Insert non-funny joke*
Let's just get to it.
Wow, this just turned serious.
Wait, no, quick Siddhant, think of something funny.
Politicians working hard.
Hahahaha. Alright, we're good to go.
a)The Alarm set/Reciever
1.Remove 3 screws from the back and remove carefully.
2.Sit back, relax and ponder upon the simplicity of life.
b)The Hand set/Transmitter
1.Remove the 'tested' sticker as well as the screw below it.
2.Don't touch the wire.Your bomb disposal training can wait.
1.Frame - This is the outer casing of the alarm set or hand set and houses all the components. The frame should ALWAYS be made of UPVC, a special type of plastic. Some manufacturer, however don't realise this and end up sacrificing the quality of the product for more durability. This is because wireless signals cannot pass through metal, thus the signal recieved by the reciever will be relatively weak. It is thus always recommended that you buy a metal one because you are a rebel and you are proud of it.
2.Bulb - Installed on both sets, it lights up when a signal is sent from hand set or recieved by the alarm set.
3.Battery - This is present in the hand set. Usually a 9V version, it can vary to AA or AAA. As the battery gets older and more used up, the signal sent becomes weaker, so the range reduces. Also, batteries INCLUDED!!! My god GLARE you just made history by being the first company to include batteries with your product! Thank you for saving humanity!
4.Transformer - This is the part which reduces the incoming voltage from the main switch to become compatible with the alarm set in this case, 220V to 12V. More Interesting information on this in the theory.
5.Antenna - This piece, present on both the alarm set and the hand set, converts radio waves to electrical waves and vice versa. The signal transmitted can have a range of 50 to 200 feet depending upon how costly it is.
6.Circuit Board - This part has multiple components soldered on to it -
b)Potentiometers - Potentiometers are variable resistors. They usually have their maximum value marked on them in ohms.

Different parts of the Cordless Bell

6.Circuit Board - This part has multiple components soldered on to it -
a)Resistor - Resistors are one of the most used components in a circuit. Most are color coded, but some have their value in Ohms and their tolerance printed on them.

| So much variety....gotta collect em all!! |
b)Potentiometers - Potentiometers are variable resistors. They usually have their maximum value marked on them in ohms.

| Different types of potentiometers |
c)Capacitor - A Capacitor is widely used in electronic circuits for blocking direct current while allowing alternating current to pass. It is thus often used to introduce a time-delay in a circuit.
d)Transistor - A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of atleast three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal.
7.Speaker - This is the large black part in front of the alarm set, and is connected to the circuit board to sound a chime whenever a signal is recieved.
There are rarely any problems that could come up in an electric bell
1.Transformer - This the most common problem that can come up in the device. The transformer can get burnt and need replacement,
2.Antenna - The antenna is a fragile part and thus breaks easily. Taping it together is a good temporary solution.
3.Water - Water can go into the device thus short circuiting everything.
How a transformer works
Basically, a transformer changes electricity from high to low voltage using the magnetic field around it to produce voltage whenever the field is changed (by moving or by changing strength).
If there's another wire close to an electric current that is changing strength, the current of electricity will also flow into that other wire as the magnetism changes.
A transformer takes in electricity at a higher voltage and lets it run through lots of coils wound around an iron core. Because the current is alternating, the magnetism in the core is also alternating.
Also around the core is an output wire with fewer coils. The magnetism changing back and forth makes a current in the wire. Having fewer coils means less voltage. So the voltage is ‘stepped-down’.
Note - Transformers typically have cores made of high permeability silicon steel as it has permeability many times that of free space and the core thus serves to greatly reduce the magnetizing current and confine the flux to a path which closely couples the windings. Early transformer developers soon realized that cores constructed from solid iron resulted in prohibitive current losses, and their designs mitigated this effect with cores consisting of bundles of insulated iron wires. Later designs constructed the core by stacking layers of thin steel laminations, a principle that has remained in use. Each lamination is insulated from its neighbors by a thin non-conducting layer of insulation.
How the electric bell works
As the button on the hand set is pressed, the circuit board, with the help of the connected the antenna, sends out a radio waves of a unique frequency in a set radius. If the reciever of the same frequency is in range, the antenna connected converts radio waves to electrical waves to inform the circuit board which sounds the alarm with the speaker.

| Man if I had a penny for every type of capacitor...thats 1,2,3,4...30 pennies. Now that divided by 100 times current rupee rate - 64, carry over the two... Rs.18000!! Wait, no forgot to divide by 1000....Rs.18!! Goddammit. |
