can anyone help me…i want ask few questions…
1)dont know what meaning of the seperated lines from image above?is it connected or not between D3 to N2?
2)how the current will flow to the buzzer since from what i learned, diode(D2, D3, D4, D6, D7) only allows one way current flow only.

See page 9 of manual (jumper J2)

Diodes are discrete ‘OR’. Check electronics textbook for theory of operation.
- ok i got it now…thank you
- for contact option, i have construct another circuit and connect with single pole double throw. then single throw i connect o the C then double throw to the ground and circuit. is it true i make it like that?because i not understand to much meaning for the “contact”.
3)is it this circuit function if i construct this circuit like schematic diagram given?because i have construct this circuit based diagram given it’s not function…but when i change the direction of D4 and ZD1 (zener diode), the circuit function well…
