home use smoke detector alarm JKD-610
Description
How to test the Smoke Alarm:
1) It is important to test this unit monthly to make sure it is working properly. Don’t use fire to test your alarms, press the test button on the cover of the unit until the alarm sounds. If it does not alarm, make sure that the unit is receiving power and test it again. If it still does not alarm, check your battery or replace it immediately.
2) The signal flashes once every 30 seconds and while it alarms the signal will flash once 0.5 per second.
3) If the alarm makes low “chirp” sounds about every 30 seconds, it tells you to exchange your battery.
4) Little smoke will not cause alarms, so misinformation occurs only when you blow smoke to the alarms directly or you forget to turn on your ventilated facility while you are cooking.
5) Sometimes when you smoke the unit will alarm, so you can just ventilate air to it to stop alarming.
