Buzzer:

The buzzer is used for alarm by the application. It is connected to MCU pin P01/PCLBUZ1
5.1.5

Description of Push Button

The push button is connected MCU pin P137 / INTP0 via R3, and used as "Reset" function. The Interrupt function can
be found in the project file "r_cg_intc_user.c"

UM-YDETECT-IT-RL78 V1.30
Function
Power supply of the MCU and others components [MCU, Alarm/buzzer,
AVDD via L1, U1 Vin (optional), pull up resistors, R16/R10 and R13/R19]:
power from battery or power from E1 via CN01-pin 5, CN02-pin 4
Caution: Battery should never be installed when using E1 power supply or
external power supply via CN02/CN01
Current measurement of the MCU and others components [MCU,
Alarm/buzzer, L1and AVDD, U2 Vin (optional), pull up resistors] by
connection of the ampere meter
Power supply of some components [R18, R17, R15, R11, J3] on glass break
detectors board
Current measurement of some components [R18, R17, R15, R11, J3] by
connection of the ampere meter
Usage of RL78/I1D comparators
(motion detector and glass break detector board)
Comparators are not used, IVREF0 & IVREF1 are not used
(CO detector and smoke detector board)
Comment
Set JP10 potentiometer for IVREF1 (DNI_J3, pin 1) = 2.0V
Approximately (0.58*VDD) at VDD = 3.4V
(Use a voltmeter with at least 10M input impedance as lower
impedance (such as 1M ) will significantly load down the resistor bias
chain).
Set JP11 potentiometer for IVREF0 (DNI_J2, Pin 12) = 1.2V
Approximately. (0.35*VDD) at VDD = 3.4V
(Use a voltmeter with at least 10M input impedance as lower
impedance (such as 1M ) will significantly load down the resistor bias
chain).
