The identification comparator circuit is by IC ₁, R ₁₈, R ₁₄, R ₁₅, D ₁, D ₂Form.R ₁₃, R ₁₄, R ₁₅Decision IC ₁The bound threshold voltage, sensor output quiescent voltage (f) is the intermediate value (4.5V) of bound threshold voltage usually, f is in the unstable variation of 1-8V, no matter at this moment f reaches high-end threshold values or reaches low side threshold values, D during as human body sensing ₁, D ₂A meeting output high level is always arranged, thereby trigger IC ₂R is adjusted in work ₁₄Resistance, promptly be to adjust sensitivity, also be equivalent to change the alarm monitoring range.

The start delay circuit is by R ₁₆, C ₇Form, as start moment IC ₂Two the input utmost points all be electronegative potential, when along with the start after passage of time, power supply then passes through R ₁₆Gradually to C ₇Positive terminal potential slowly is upgraded to noble potential, to D this moment ₁Or D ₂The output noble potential just can make IC ₂Output terminal is noble potential, thereby triggers the electronic switching circuit action.Start time delay and R ₁₆And C ₇Value be directly proportional, the start of this machine is 20 seconds time delay.

IC ₂, R ₁₈Play signal and amplify shaping operation.C after the start time-delay finishes ₇With R ₁₈Between be noble potential all the time, as D ₁Or D ₂Output high level, then IC ₂Output terminal then has the noble potential that has amplified be added to BG ₅Base stage, at this moment trigger sensitivity is very high, for fear of the false triggering that small-signal causes, R ₁8 play a role.

On-off circuit and topworks are by BG ₅And J ₁Form, usually BG ₅Be cut-off state, work as IC ₂BG during the output high level ₅Conducting immediately, then J ₁Get electric adhesive, J ₁-2 connect the road work of the alert acoustic-electric of (see figure 10), J ₁-4 connect (see figure 10) camera head circuit connection work, J ₁-1 connects the (see figure 10) bulb gets electroluminescence.

In order to make the various functions energy of machine fully automatic working, BG ₆, BG ₇, C ₈, R ₂₀Play control time action automatically.Generally because C ₈Two ends all are noble potential, BG ₇Conducting, BG ₆By (BG at this moment ₅Also end).J ₁Be failure to actuate if any signal triggering BG ₅, make BG ₅Conducting is J then ₁Get electronic work, J ₁-3 moving plate ground connection are at this moment because C ₈Discharge process, make BG ₅End BG ₆No matter conducting is BG at this moment ₅Be to end or conducting J ₁All get electricly, various functions are normally carried out, along with C ₈Last discharge finishes, and power supply passes through R ₂₀Give C again ₈Charging, after a break time, BG ₇Become conducting, BG by ending ₆Become and end (as the BG of no signal triggering at this moment ₅) J then ₁Dead electricity, all functions fail this process for controlling timing automatically, and it is length and C regularly ₈, R ₂₀Numerical value is relevant, and this machine regularly is 40 seconds.

IC ₃For integrated circuit, IC take place in alert sound ₄Be audio frequency power amplifier module, generally J ₂-1 closure, J ₁In a single day-2 disconnect (see figure 10) signal triggering BG ₅Make J ₁Get electric then J ₁-2 closures, loud chimes of doom takes place in whole alert acoustic-electric road effect, surveys to export frequently between this machine that to reach 4W many.
