[Alarm] Fire Smoke Detector Circuit Diagram Operation System: Basic Smoke Detector Operation Circuit

As previously post describing how to use initiating device circuit IDC in basic fire alarm circuit operation, the circuit schematic above appears how can this basic fire alarm circuit system ring a bell in smoke detector using such operation.

When the voltage VZ is the same value as VS, it surely may kick an alarm response and then ring the bell. It can be happened when the pull station in the smoke detector is triggered and puts a short for terminals 1 and 2.

In the voltage sense circuitry there can be three voltage condition. voltage zone Vz can have the same voltage as voltage supply VS and then ring the bell, VS has doubled VZ means normal operation and nothing happened, and VZ has 0 in voltage which means troubled.
