Connection of music alarm detection components

If different detection components are added to the alarm circuit , alarms for different purposes can be formed.
    Figure 13-44 is a music alarm circuit, using C2875E music
circuit.
    If various detection components as shown in Figure 13-45 are added to the alarm circuit in Figure 13-44 , the following various alarms will be constructed .     Figure 13-45 (a) is for magnetically controlled proximity alarm; Figure (b) is for magnetically controlled removal alarm; Figure (.c) is for temperature alarm; Figure (d) is for moisture sensitive alarm; Figure (. e) is for light-controlled alarm; Figure (f) is for sound -controlled alarm; Figure (g) is for liquid level alarm; Figure (h) is for over-voltage alarm; Figure (i) is for inductive high-voltage alarm. Alarm distance: 2.5-8m at lOkV high voltage; 5-20cm at 220V mains power.
