In the smoke detector, the fast - moving alpha particles enable the air to conduct an electric current. As long as the electric current is flowing, the smoke detector is silent. The alarm is triggered when the flow of electric current is interrupted by smoke entering the detector.
The device that senses the current flowing and trips the circuit to cut off electricity is called a Residual Current Device (RCD) or Residual Current Circuit Breaker (RCCB). It detects imbalances between the live and neutral wires, which can indicate a leakage current, and disconnects the circuit to prevent electric shock or fire hazards.
Blown fuses indicate overload in the electrical circuit. Possible short-circuit or higher input voltage.Tripped circuit breakers I guess means:A residual-current device (RCD), similar to a residual current circuit breaker (RCCB) which is used for breaking the circuit when electric current pass through a man or could cause fire/burning in the/near the electrical sockets.
Americium-241 is used in smoke detectors because it emits alpha particles that ionize the air inside the detector. This ionization process allows a small electric current to flow between two electrodes in the detector. When smoke enters the detector, it disrupts this current, triggering the alarm.
The purpose of a residual current device (RCD) is to compare the currents in live and neutral wires. These should be the same. If they are not, then current must be flowing to earth- perhaps through someone touching an exposed wire. The RCD senses the difference and switches off the current before any harm can be done.
Residual current as in a residual current device or RCD (sometimes known as a earth leakage detector), refers to the current both entering and leaving a circuit. If more current flows into a circuit then comes out (if there is a ground fault or if someone gets a shock) the RCD will switch off the circuit. Typically the current required to trip a RCD is around 5-20mA, however even 5 mA can be enough to stop your heart, so RCDs are a good safety device but should not be relied on.

When a convection current detector comes near a heat source, it will detect the movement of air or fluid caused by the temperature difference. This movement creates a convection current around the heat source, which the detector can measure to indicate the presence and intensity of the heat source.
Ionization in a photoelectric smoke detector helps detect smoke particles by creating an electric current when smoke enters the detector chamber. This current triggers the alarm, alerting people to the presence of smoke and potential fire.
Residual overcurrent protection is often provided in modern microprocessor based relays that have three phase inputs, and no neutral input. Sometimes this is provided even if a neutral input is present. It is similar to neutral overcurrent, where the neutral current is directly measured through the neutral input of the relay. for residual overcurrent, the three phase currents are vectorially summed together to form the residual overcurrent. This relay measured 3I0 current, or ground current.
A residual-current device (RCD), or residual-current circuit breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the electric currents not balanced between the energized conductor and the return neutral conductor.
The battery in a smoke detector should last a year (though the detector should be checked monthly). The detector works on "trickle" current that is always there. NiCads will lose more current than an alkaline battery from just sitting around - much more. Even a fully charged NiCad will usually not last a year in a smoke detector. Alkaline batteries will easily.
