This smoke detector adopts photoelectric detector.Photoelectric techology is more sensitive than ionization technology at detecting large particles.Fire is dangerous. We need to install at least one in our bedroom.Stairway is very important for people to rush out when fire occurs.So there must install smoke detectors.Install the smoke detector in the middle of ceiling,because smog and heat always lift up to the top of room.

*Power supply: 9V DC battery

*Static current:20uA                            

*Alarm current:10mA                         

*Alarm sonority:>85dB                    

*Working temperature:-10℃--+40℃

*Working humidity

*Photoelectric Sensor,LED indicator

 

*Test: After installation we must notice whether the led flash once about 40sec or not, if do, that shows normal.

Press and hold the test button on the cover,the smoke detector should sound.The alarm sound should be loud and pulsating.And while it alarms,the led will flash once a second.That indicates the smoke alarm is operating correctly. If the alarm makes low chirp sound every some time,it tells us to replace battery.Sometimes when you smoke, the unit will alarm, so you can just blow air to it to stop alarming.

This smoke detector adopts photoelectric detector.Photoelectric technology is more sensitive than ionization technology at detecting large particles.

* Model LX-224AC/DC can be connected with mains power(110-220V AC). The smoke detector has a built-in 9V battery as backup power.

It can work normally in the event of a power outage.

*The smoke detector is power saving.Static current is less than 100uA.Alarm current is 12mA.But alarm sonority is higher than 85db at 3meters distance.

*Test: It is important to test the detector weekly to make sure it is working properly.

1.Press and hold the test button on the cover until the alarm sounds.If it doesn’t alarm,make sure the unit is receiving power and test it again.If it still does not alarm,replace it immediately or check the battery.

2.The light flashes once every 30 seconds in normal state, the light flashes once every 0.5 second while it alarms.

3.If the alarm makes low”chirp” sounds every about 30 seconds,it tells you to exchange battery.

* Model LX-223 is a stand alone smoke detector supplied by a 9V battery.   *Photoelectric sensor,high sensitivity *Red led indicate alarm *The smoke detector is power saving.Static current is less than 20uA.Alarm current is 10mA.But alarm sonority is higher than 85db at 3meters distance.   *Test: It is important to test the detector weekly to make sure it is working properly.Firmly press and hold the test button at least 5 seconds,the smoke alarm will sound 3 short beeps followed by a 2-second pause and then repeats.The alarm may sound up to a few seconds after releasing the button.

Model LX-222 smoke alarm adopts photoelectric technology to detect smoke.It is more sensitive to slow smoldering fires and more quick to remind us. Keep our home safe.   This smoke alarm is a stand alone detector supplied by built-in 9V battery.   Red led indicates alarm.Built-in sounder will give sound output of minimum 85db at 3m distance.   The test button accuratly tests all smoke alarm functions.Do not use any other test method. Test smoke alarm weekly to ensure proper operation.
