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
Normal operation
Optional REGC = 1.8V to AVREFP (with SW change)
Optional AIC1702L-25 output = 2.5V to AVREFP (with SW change)
Use less – no amplification of trans impedance amplifier
May bypass with Resistor to change the Impedance
Filter (R45 & C20 used) between Amp0 Out and Amp0 –
Direct connection to Ground (please check schematics for more details) - no
influence for the CO detector application
R32 is used (please check schematics for more details) - no influence for the
CO detector application
Function
Could be used when J3 is closed (please check schematics for more details).
Could be used when J3 is closed (please check schematics for more details).
Function
INTP0 is High – no operation
INTP0 goes Low – no operation
