PD-SO-215 is a digital low-power smoke alarm, product

design follows the EU EN14604 standard, the use of

high-performance chip as a stand-alone photoelectric smoke

fire alarm MCU, digital signal processing makes the alarm

detection more Accurate, better product sensitivity

consistency, MCU built-in FLASH memory, store the

detector's factory parameters, maintenance information, to

achieve a strong self-diagnostic testing, circuit failure, sensor

failure, battery voltage and other parameters of the detection

and diagnosis. At the same time, adaptive compensation

function will be based on ambient temperature, external

factors such as changes in the conditions of fire sensitivity

compensation to the appropriate range, enhanced product

stability. The average standby current of the product is less

than 3uA standby power consumption, working time up to 10

years.
