12-11) MODEL OPTION CIRCUIT
1) This circuit operates with the initial power on and uses DIODE (1N4148).
To modify the option circuit,the power should be turned off before being modified and turned on after
the modification.
Refer to the table above,the default factory values are highly recommended unless exceptional cases.
12-10) Buzzer Circuit Diagram
1) The circuit is composed of like the above and MICOM controls the alarm function with 2KHz.12V is
always applied to the circuit.So,when MICOM sends alarm signals to Q801 Transistor Bass,the
transistor is turned on applying 12V to the buzzer,which operates the buzzer. 4.7Kohm of R801 is a
resistance for the production of quality buzzer sound.
