Smoke Alarm With 10Y Sealed Battery

LM-107A Fire Detecting Alarm Use Manual

1.Brief introduction

LM-107ABCfire detecting alarm is composed of sophisticated analog circuit and digital circuit. It is a kind of low power consumption, low voltage photoelectric independent smoke alarm with 3v lithium manganese battery, this battery can last for 10 years.

2.Characteristic

◆ photoelectric smoke detection；

◆ High sensitivity；

◆ Local smoke alarm memory;

◆ within normal detection mode and low sensitivity detection mode (hush);

◆ within built-in 10 years lithium manganese batteries, battery cannot be replaced;

◆ 10 years life end warning tone

◆ low voltage warning tone

◆low power consumption.

3.Parameter

Technical parameters	Smoke detector
	Voltage	DC3V（built-in CR123A）
	Low-voltage inspection	2.2V
	current	Working current	Quiescent current
		≤120mA	≤2uA
	Status display	Normal smoke detection	LED (red) flashes once every 344 seconds, no alarm sound
		Smoke detection or key test	LED (red) flashes and continuous alarm is given
		Low sensitivity detection (silent mode)	LED (red) flashes every 10 seconds, no alarm sound, automatically cancel low sensitivity detection about 9 minutes later
		Alarm memory	LED (green) flashed 3 times every 43 seconds, and stops 24 hours later. The first time you press test/mute button after alarm is made, the detector will hint by special alarm mode.
		End of useful life	After working for 10 years, alarm sound is made, the buzzer buzzes 3 times every 43 seconds
		Low-voltage inspection	LED (red) flashes once, make “di” alarm sound for about 43 seconds
	Alarm loudness	≥85dB/3m
	Working temperature	-10℃~+40℃
	Ambient humidity	≤95%RH（no condensation）
