Detailed Description

This circuit has three main parts:

1.

Alarm Audio Signal Circuit: The alarm audio signal circuit is made up of components
including U3, U6, R8, R25, E6 (E1), R11, R12, R3 and R32. P3.3 is used to control the
length of the alarm sound. R8, E1 and E6 are used to generate the rise edge and the fall
edge of the sound signal. Q1 is used to make the rise edge and fall edge of the low-
level alarm slower than those of medium/high-level alarm. D1 is used to generate the
heart beat and pulse tone. If P3.2 is high, the alarm square waveform of P3.5 will pass
and, as a result, control P3.2 to generate a "heart beat tone" or ‘‘rotary encoder tone’’.
R11, R12, R3, R32 and R18 together construct a variable voltage-dividing network
which, by controlling the state of RA and RB via U3, determines the sound volume level.

2.

RC Bandpass Filter/Audio Amplifier: A one-stage RC bandpass filter is used to block the
low frequency component of the alarm signal (700 Hz. square wave) before it is input to
the audio amplifier, LM386. This bandpass filter is made up of R13, R28, C9, C15, RA
and the input resistance R in of LM386.

3.

Alarm Indicator Control/Encoder and Key Scanning: The flashing of the alarm indicator
in red or green is controlled by the state of microchip P1.6 and P1.7. The
microprocessor scans the state of microchips P1.0~P1.2 to determine which key, or if
the encoder, is pressed. The microprocessor scans the state of microchips P1.4 and P1.5
to determine if the encoder is turned and in which direction it is turned.
