I.Bell Wiring Materials Quiz

Electric Bell = A device which reduces the house voltage of 220 volts down to 6 volts Bell Transformer = A signaling device used to call the attention of a big number of people Friction Tape = A sticky strip of cloth used as insulating materials on electrical joints Push button = An electrical material that closes the circuit when you push it

Bell wire = Used to attach or fasten the bell wire to the wood surface Insulated staple = Used to carry electric current from the transformer to the bell Push button = Used to automatically open the circuit when released Friction Tape = Used to insulate electrical joints

Bell wire = A sticky strip of cloth used as insulating materials Friction Tape = A stranded or solid copper wire used in bell wiring installations Insulated staple = A piece of metal material with a paper or plastic insulator at the base Bell Transformer = A device which reduces the house voltage of 220 volts down to 6 volts

Bell Transformer = To call the attention of a big number of people Electric Bell = To reduce the house voltage of 220 volts down to 6 volts Push button = To insulate electrical joints Friction Tape = To close the circuit when pushed

Push button = A device which reduces the house voltage of 220 volts down to 6 volts Bell Transformer = An electrical material that closes the circuit when you push it Insulated staple = A signaling device used to call the attention of a big number of people Bell wire = Used to attach or fasten the bell wire to the wood surface

Friction Tape = A type of wire used in bell wiring installations Bell wire = A type of insulating material used in electrical joints Insulated staple = A type of electrical source used in place of a transformer Bell Transformer = A type of electrical material used to close the circuit when pushed

PUSH BUTTON SWITCH (NORMALLY OPENED) = Wires connected PUSH BUTTON SWITCH (NORMALLY CLOSED) = Wires not connected CIRCUIT BREAKER = Bell alarm annunciator buzzer BELL TRANSFORMER = AC source

The bell wire should not be installed near lighting circuits. = Prevent bell wire from high voltage lines An extra length of wire should be provided at bell terminals. = In case bell is moved to another location All bell wires should be hidden along the top surface of the wall. = Aesthetic and concealment reasons The usual size of bell wire is No. 18. = Use bigger wire if total length is more than 20

Bends should be at right angles, no diagonal wiring. = Attachment of bell wire along wood panel Kinks or deformities should be straightened using a screwdriver. = Straight wire for beauty and economy Insulated staple should be hammered with care. = Prevention of cutting the bell wire Proper insulation with friction tape for joints. = Ensuring secure connection

Location of bell near the center of the house. = Centralized sound distribution Push button installation at the front gate, minimum 5 feet from ground. = Convenience and standard height for users Parallel conductors should have equal distance between them. = Ensuring uniform and balanced connection Coil made at the bell terminals. = Extra wire in case of relocation

Pictorial drawing = Shows objects as seen by the eye with true shapes and sizes Schematic drawing = Illustrates circuit parts using symbols

Bell wire attached horizontally or vertically along wood panel. = Avoiding diagonal wiring Diagonal wiring should be avoided in bell installations. = Prevention of improper connections Straightening kinks or deformities in the wire. = Maintaining wire integrity and appearance Installing wire away from lighting circuits. = Safety from high voltage lines
