Introduction multiplexer demultiplexer?
A multiplexer, commonly referred as an input selector, is a circuit with many inputs but only one output: it has some data inputs, control inputs and one output, depending on the control inputs, one input from the data inputs is sent to the output .A demultiplexer is a circuit with one data input, few control inputs and many outputs, it is also known as output selector.
What is thyristors?
A thyristor is a part of a alarm circuit you use it so the alarm stays on
A logic circuit which determines if one input is equal to another is called?
A XNOR gate for comparing 2 inputs
What is a AND circuit?
An AND circuit is a circuit that takes two or more inputs, and generates an output that is the boolean AND function of those inputs. Two light switches in series, for instance, is an AND circuit because both switches have to be on for the light to be on. If the switches were wired in parallel to each other, and then in series with the light, that would be an OR circuit.
How does power supply failure alarm circuit works?
Power supplies don't fail. Idiot.

What is the main function of resistances in fire alarm circuit?
Heat changes the resistance of a circuit. The change is detected by the system, and activates the alarm.
What is thyristors?
A thyristor is a part of a alarm circuit you use it so the alarm stays on
What is the input and output of an alarm?
the inputs are the sensors that detect intrusion, the outputs are the siren and the lights
What is the inputs of a smoke alarm?
It is a thingy that rings when a fire is goingto happen or something like that.
Does a fire alarm circuit have to be in a separate conduit?
yes because of it having a signals, if it mix with power cable, fire alarm circuit get distributed.
How does the AND circuit work?
It requires two inputs before the output turns on.
Why to use pnp transistor in fire alarm circuit?
You can use a PNP or an NPN transistor in a fire alarm circuit. Both will work. It all depends on how you want to energize the alarm, and with what polarity of signal.
Alarm circuit for the train in same track?
no
What is combinational circuits in computer architecture?
combinational circuit is depend only on inputs,like sequential circuits its not depend on previous outputs.
What is a function of a resistor in a fire alarm circuit?
A resistor in a sensor circuit is used as a simple way to monitor the function of the circuit. The resistor has a calibrated and known voltage drop and current while the circuit is "normal". If there is a short-circuit, or an open-circuit, the voltage and current will change and trigger the trouble alarm.
How does the AND safety circuit work?
It requires two inputs before the output turns on.
